PVC injection molding

PVC injection molding

What is the PVC?

It is Polyvinyl chloride polymer. It is thermoplastic resin with the cheapest cost.  Natural color is white or light yellow or translucent light yellow. PVC is one of most common resin using in the world.

Mechanical properties of PVC plastics depends on the relative molecular weight of polymer, plasticizer content and filler. In general, the filler content increase, decrease of tensile strength. Without the addition of plasticizer PVC is hard plastic. Adding plasticizer, softness, elongation and freeze resistance increased;  Tensile strength, glass transition temperature, brittleness and hardness, etc. are reduced

PVC began to soften at 65-85 ℃. 170 ℃ into began to viscous flow state.140 ℃ little decomposition, decomposition rate is increased with the increase of temperature, 190 ℃ produce a large amount of HCL gas. The chlorine content of PVC was as high as 56%, which has a flame retardant and Zixi; but also has good dielectric properties of electrical insulating materials, is excellent. In addition, PVC is a poor thermal stability of the polymer, can gradually break down to release HCl in optical and thermal effect, at the same time, oxygen, ozone, cyanogen chloride and some active metal (such as copper, zinc) ions, the degradation speed

PVC injection molding parts application

PVC injection molding parts used for plastic pipe fittings, electric socket, electric box, electric meter enclosure, shoe sole， automotive plastic part, electric product enclosure and construction plastic parts(window framer, plastic accories on window, tube connector and floor board) etc.

Tips for PVC injection mold quotation and inquiry

Choose the right steel for PVC injection mold, you should choose the corrosion prevention stainless steel due the there is a little HCL gaseous fluid during the PVC injection molding. Normally you can choose 420 SS.For big amount production, if you choose the LKM steel, we suggest you choose LKM 2316(h); For ASSAB steel, you can choose ASSAB S 136(h). Regarding the DAIDO steel, you can choose NAK80 . If you just need the make the prototype mold for PVC injection molding, you can choose still the S50C and aluminum. If you can not specify this, your mold supplier will offer big difference price on your price list.

Choose the right cavity for PVC injection molding, normally the cavity quantities is based on your mold life and your plastic product, you can also choose family mold for PVC mold. Sometimes you missed to specify this, you will get lots of big difference price from China mold company.  This is very easy to specify, you can review the mold life post to learn more. You can also ask your suppliers to consider the most economical solution for the cavity.

Tell your China mold maker of the mold base steel and mold base specification(DME, HASCO or LKM or LKM EQV).  If you do not mind what kind of mold base. You can choose the LKM standard mold base thanks to this is the most economical and qualified solution for the mold base in China. For the mold base with HASCO and DME guide system and components, most of China mold supplier is custom made from the mold base company, the inferior strength is expensive and quality is not stable compare to the standard mold base.

Specify if you need hot runner system and brand. Normally for the famous hot runner system such as DME ,HASCO ,INCOE ,YUDO, Synventive, HUSKY, Mastip and MOLDMASTER etc. It is all available in China. But the cooperation between your China mold supplier and hot runner system provider is not the same. If you need the leave the mold in China for production, then your mold maker will consider this. Otherwise you should consider if you need to use hot runner to save the resin cost or your product need the hot runner to have better quality or your plastic product really need the hot runner as limited on the plastic product structure and mold design.

Clear plastic enclosures for electronics manufacturing solution

Clear plastic enclosures for electronics manufacturing solution

We will talk about clear plastic enclosures for electronics manufacturing solution from the design to the manufacturing on this post. We will show you the normal clear plastic enclosures for electronics manufacturing solution, also it is the cost saving and safety solution.

Clear plastic enclosures for electronics design

Clear plastic enclosures for electronics design is similar as the common plastic enclosures design, but you had better to have simple structure inside as possible as the structure inside of the clear plastic enclosures can be saw.  We should consider the mold ejection during clear plastic enclosures design as the worse ejection will leave the ejection pin mark insider of the clear plastic enclosure, it can be saw.

We should consider if we need ejection plate for ejection or ejection pin for ejection during the design, ejection plate for ejection will not leave the ejection mark on the clear enclosure, but we can not have lots of ribs inside of the clear enclosure, otherwise it is not possible to release the part from the mold.  Ejection pin ejection will leave the ejection pin mark on the clear enclosure, we should consider a good position to locate the ejection pin to make sure it affect the cosmetic issue as less as possible.

Clear plastic enclosures for electronics prototype manufacturing solution

Clear plastic enclosures for electronics prototype can be manufactured with plastic casting, CNC machining and SLA prototyping process. We should consider the clear plastic enclosures structure to choose the clear plastic enclosures prototype manufacturing solution. For more, please kindly review our post “Transparent plastic prototype manufacturing” .

Clear plastic enclosures for electronics mold manufacturing solution

Core and cavity steel for clear plastic enclosures for electronics mold manufacturing

This is very important to start the clear plastic enclosures for electronics mold. If you choose the wrong steel, you will waste money and time, sure you will have lots of trouble and have lots of wrong work.

1, If you order quantities is very low, something like 1000pcs each time and total demand is less than 10,000 pcs, you can consider normal steel such as P20, 2311, 2312 and 738 etc. preharden and non-stainless steel.

2, If you demand is more than 10,000pcs, we have to use through hardness 420 stainless steel.  We always suggest to use 420 stainless steel to have the good quality and save time on the polishing times.  Please kindly noted that there are lots of kinds of 420 stainless from different steel supplier.

The other things we should noted on the clear plastic enclosures for electronics mold manufacturing

• Running the mold flow and have the design for manufacture for clear plastic enclosures to find out if there is possible on flow and injection


• Use the inserts for the core and cavity as possible as the insert change will save cost than to change a whole cavity or core, please noted plastic make sure this will not affect the cosmetic surface.


• No welding on the surface core and cavity, otherwise it will be possible to see the defect on the molded clear plastic enclosures.


• Be careful to manufacture each components of core and cavity, if you made mistake, the remedial measure will less than the common mold.


• Choose the master to finish the polishing, not save cost on the polishing otherwise you will pay more


• Check the mold polishing surface before the mold trial

Clear plastic enclosures for electronics molding production

• You should have same strict quality control for the molding for this kind of molding. But you should pay more attention as below:


• Clear plastic enclosures surface


• Clear plastic enclosures welding line check


• Protect the clear plastic enclosures, you can use the plastic polypropylene sheet to cover the clear plastic enclosures, normally you can buy this common plastic sheet, you can told your plastic sheet supplier this is to use for clear plastic part surface protection. You never use the PVC sheet to protect the clear plastic enclosures, it will make the surface very bad.

Turnkey to compare plastic molded product manufacture price

Turnkey to compare the plastic molded product manufacturing price

Have you faced below issue during your inquiry

• Price is very big difference from your China mold supplier


• Unbelievable high price


• Unbelievable low price

How you can do this better to compare the mold and plastic molded product manufacturing price ?

If you are professional I think you can do this for the mold quotation

• Specify the mold steel


• Learn what steel is available in China and price level


• Specify the mold life


• Specify the mold base


• Specify the mold cavity


• Specify the resin with supplier brand


• Specify the surface fining for your product and mold

If you would like know more, read below

When you specify themold steel not just specify H13 or P20 etc., you can specify the steel like LKM H13 and Finkl P20 etc. You can specify the mold steel company brand as the price from different company are difference.

For the mold base, most of customers need the DME or HASCO standard thanks to that the components can be interchanged in North America and Europe.  To fulfill this demand China mold base supplier meet the market demand to custom make the mold base with DME components or HASCO components, this kind of mold base is still cheaper than the original mold base from HASCO or DME, but it is more expensive than the China standard mold base.

To be honest, China LKM mold base should be the best on based on economy and quality.

Custom standard mold base is more expensive than the standard one. Normally it is from two to three times more expensive.  Most of the non-standard mold base is custom made in China mold base company.

Same resin from different resin supplier is not the same.

If there is any simple way not request so professional as I just start to purchase the plastic molded products?

• You can inquiry from one of mold supplier what looks very professional


• Tell your mold company that you need economical or high quality


• Ask your mold supplier to specify the information like mold steel, mold life, mold cavity and steel supplier etc.

If you just need the plastic products and no need to move the mold in your country

Basically, tell your molding supplier:

• What kind of quantities you will order each time


• How frequency you will order


• The plastic product life (like how long you will order this product  or you would like to use this mold to produce how many parts)


• Plastic product surface finishing or secondary process


• What your plastic product used for

If it is multicavity mold or you have lots of product to make, tell your molding manufacturer:

• Plastic product color


• Potential color change for each product


• Each plastic part dosage for a final product


• Where the accurate area on your product is


• Where the fitting area for each component is

Above information will be useful for your mould supplier to specify the mold cavity such as muticavity and family mold. The mold supplier will consider the  economical and quality as well as secondary for your plastic product

We will share more details on our newsletter, may offer some toolkit to make this quotation work easier.

Transparent plastic prototype manufacturing

Transparent plastic prototype manufacturing

There are a few process to have transparent plastic prototype manufacturing as following:

• CNC machining process with PMMA


• Plastic casting process


• SLA process


• 3D printing

We can choose transparent plastic prototype manufacturing process based on your demand such as qualities, use and function etc.

CNC transparent plastic prototype manufacturing

This is common widely use transparent plastic prototype manufacturing process. If you need high quality transparent plastic prototype such as plastic lenses, transparent cover and transparent enclosure, transparent enclosure and transparent led lamp enclosure etc. You can choose PMMA CNC machining process.

Sure it is also okay to machining with polycarbonate , but the polishing process is more difficult to control than PMMA, we did not suggest to use this resin to make transparent plastic prototype for  lens or high smooth transparent part.

Plastic casting process

This process to make the RTV silicone mold to cast plastic prototype. You can lean more from our another blog, post is plastic casting prototype . You can also review resin casting on Wikipedia.org.

Plastic casting transparent prototype can be polished too, but it still worse than PMMA CNC machining prototype.

This process can make transparent plastic prototype, the material is not really resin what we used for injection molding, it is cast two kinds of liquid chemical compound into silicone mold to form plastic parts. If you need plastic parts with FDA, please do not consider this process.

Also plastic casting prototype surface finishing is worse than the PMMA CNC machining process, if you need high quality smooth transparent parts, please do not use this process.

Transparent plastic casting prototype is cheapest process to copy transparent parts. Also it can be copied complex transparent plastic prototypes.

SLA to have transparent plastic prototype

SLA rapid prototyping is a discrete layered, layer by layer stacking technology, the direct use of three-dimensional computer data is implemented as a prototype of the product, the more mature laser technology both SLA and SLS rapid prototyping, which the SLA the main material for the photosensitive resin.

SLA rapid prototype’s advantages:

A smooth surface, and good quality.

Forming high precision, and accuracy of 0.1mm;

Can be made very fine details and molding of thin-walled structures, high precision, easy post-processing.

Processing cycle is short, usually it is three days.

SLA transparent prototype manufacturing is weaker than the PMMA CNC machining prototype and transparent plastic casting prototype. Also it is more expensive than both of transparent prototypes. SLA transparent manufacturing process can have complex plastic prototype even if you have lots of undercuts.

3D printing transparent plastic prototype manufacturing

Here we just call the desktop 3D printing prototype. Generally, this process can not get a high quality smooth surface finishing transparent prototype. But the prototype is stronger than plastic casting one.

As the technique developing, we hope this process can be widely use to copy transparent plastic parts. Also right now this process is more expensive than plastic casting prototype manufacturing.

Turnkey solution to control plastic injection molding tolerance 1

Turnkey solution to control plastic injection molding tolerance

There are lots of people are talking about that how to control the tolerance for plastic molding. I combine my experience with a few exporter who have more than 20 years experience for molding industry. I hope following information will be very useful for you.

What will affect the plastic injection molding tolerance

• Plastic injection molding resin


• Mold manufacturing & injection molding project management including engineers, sales & communication etc.


• Plastic injection mold machining accurate


• Mold design concept


• Molding parameter


• Injection molding machine quality including brand, local or import one


• Injection molding machine selection including machine size, screw diameter, injection volume and clamping force etc.


• Quality control including inspection of mold components, electrode and plastic products

First of all we talk about the mold manufacturing & injection molding project management

Lots of people miss to control this on the plastic product tolerance. This is first process we should control the tolerance. We should control from the samples if you are mold factory, if you are mold or plastic product buyer, you should control this on the information offer process.

What we should offer to mold manufacturing factory and molding factory or ask from buyer to control the tolerance?

Plastic product 2D drawing: There should be tolerance label for all of the dimensions. This is target what customer need to reach. If you have surface finishing and secondary process for this products, please offer this information on the 2D drawing. Also please throw away the habit to talk to your mold manufacturing supplier for this kind of requirement on email. If not, you have risky to have your supplier to miss information if the one you are working have no good project management.

Plastic product 3D drawing : Have this drawing to provide to your plastic mold maker, then they check the details of the plastic product on the drawing. Also if your good and professional mold supplier limited on the capability, they will reply you.

I suggest you to read plastic injection mold life on our blog to know more about that the mold life for the tolerance and cost. Normally the accurate mold should be made with through hardness core and cavity. Please offer mold life for mold manufacturer.

Above process is to control the plastic product tolerance during the quotation, this is the communication process, and is the basic process to have tolerance under control.

How Seasky Tooling to control the tolerance on the quotation process?

• Lessons for all of the salesman to understand what we should ask from customer


• what we should ask based on different customers


• We clean individual cases up during our service, use this to help you and our salesman


• We have easy understanding form to collect customer demand to our CRM


• Professional engineers coordinate with salesman to check and study the information from you


• Also most of salesman have mold engineer experience

Based on above, we make sure we can get the enough information from you to proceed the quotation and assure you have no risky to miss the tolerance control.

Control the tolerance on different plastic resin

This is one of most important process to control the tolerance.  Different resin on injection molding with different dimension even if it is the same injection mold due to different resin with different shrinkage.

For the POM, PP and PE etc resin, they have big shrinkage, it is more difficult to control tolerance than PC, ABS, Nylon with glass fiber and PC/ABS etc. Normally PC, ABS and ASA etc. plastic resin with shrinkage lower than 6 ‰ is easier to control a few dimensions with +/-0.02 mm, assure it is possible to control to more accurate tolerance for a few dimension. We do not suggest to use the high shrinkage resin to have accurate plastic parts.

Control the tolerance on plastic mold design process

This is one of whole process to check the information provide by customer and manufacture the information on plastic mold design and input on plastic mold factory for mold manufacturing. Your mold supplier should consider following for the mold design and even more than these:

• Plastic resin shrinkage


• Plastic product gate location


• Safe steel for accurate dimensions


• Use the inserts as possible for the accurate dimensions


• Use the inserts as possible for the easy breaking feature of mold


• Consider the suitable injection molding machine


• Learn the plastic resin specification and input this on the mold design


• Consider the molding parameter during the mold design


• Prepare the solution to prevent the deform, short shot, burning etc. common issue during injection molding


• Mold designer have full check list to check the mold design even if you think you are very  professional


• Run the mold flow to test the mold design and plastic product design


• Optimize the mold design and plastic product design

Control the tolerance on plastic mold manufacturing process

• Choose the right process to manufacture plastic mold components


• Inspect plastic mold components including the electrodes and mold inserts


• Assure the plastic mold components is accurate


• Relieve the stress for the large mold core, cavity or mold plates after manufacturing


• Measure the plastic mold components and record


• Inspect plastic products dimensions after injection molding trial and record


• Measure deviated dimensions on the mold after mold trial. Find the clue to improve the dimensions on the mold


• Choose the right injection machine according to your injection mold including choose the right screw of injection machine based on the resin and plastic part, clamping force, injection volume, Min-Max mould thickness and ejector stroke etc.


• Record the molding parameter during mold trial, not only the parameter on the injection machine. You should also record the mold temperature, test the actual temperature of mold and set up temperature of injection machine.

Plastic injection molding tolerance control

If the mold is released for mass production, you should also control the tolerance of the injection molding parts. First of all you have to control the whole dimension, at least you should measure the biggest length,width and height of product. If this have no big change, this means your injection parameter should be correct probably.

Give more importance on the first 100 shots once you start the production. Once the mold running a few hours, the parameter should be not the same, you should check the tolerance, this is the reason why we suggest to check large size and accurate dimensions each hour. Please noted the mold trial is different as the production. Even if you got a good shot on mold trail, it is not the case you can get a good shot on long time production. Please check and record, you will learn lots of information.

Also you should measure the accurate dimension at least per hour to make sure it is correct. You can measure it more frequent based on your production quality control.

You should also check the following things during injection molding

• Plastic injection molding parts color


• Plastic injection molding parts surface finishing


• Plastic injection molding parts small feature including ultrasonic welding line, small bosses, small posts and small ribs etc.

Qualified mold supplier or just low cost mold supplier,Choice lead to succeed

Qualified mold supplier or just low cost mold supplier,Choice lead to succeed

Till now, I Hedy worked for mold manufacturing and molding international business 9 years. I discussed lots of inquiry with different customers. During the communication, I have the attitude to solve the problem of what customers faced with the other suppliers or offer hands to support for customers’ plastic product development. I also faced the situation what they ask the price lower than the plastic molding resin, but it is low probability to face the ask the price less than the mold steel[/tooltip].

I also understand sometimes you request the cost less than the resin cost for your product, normally you should choose some of equivalent resin to reach your demand or your plastic product, if there is no this kind of resin and your mold supplier offer the cost than the resin, then it is risky, then what kind of risky, one of reason maybe the molding supplier is talker.

I also hate someone to offer the high price and  himself believes that  their quality and lead time is the best. We are always to learn the solution the reduce the cost without affect the quality even if it is our competitor, we would like to learn.

What the qualified mold supplier can help you and what will be the qualified mold supplier?

Qualified mold supplier always give importance on the details to improve the customer experience and have good time control!

Time is also the cost, lots of friends miss to evaluate this during the mold supplier audit.  We can not just evaluate the lead time on the quotation what the mould supplier offered. After the T1, the mold supplier also should have the very good capability and time control to improve the mold defect or have the mold modification.

The qualified mold supplier always give importance on  the details to short time, improve the quality and save time for customers. This is to improve the customer purchase experience. For example, qualified mold suppliers always reply your email on time and also mentioned what you missed to offer for them to proceed injection mold manufacturing or injection molding. Qualified mold company will always save your files and their files for the mold manufacturing and injection molding regularly, and it is easy and very fast to offer the document what you need. Qualified mold factory will always listen your suggestion or ask your suggestion or feedback to improve their service to support you.

Exchange information faster as time goes on for injection mold company

Exchange information including the exchange the ideals for your product, mold design and data and files as well as injection mold company inner management. These things will go faster and have to be like this. This is the time control on communication and quality.

For example, the ERP system is to reduce the repeat work, short the communication time, streamline and standardize working flow and make the date more useful etc. This is also to short the time.

Long term cooperation, companies have the choice to work together have long term cooperation.  The two company will understand each other for the product development, communication solution, mold design, mold manufacturing, qualify, lead time and shipping etc.  The time to understand each other save the time to communicate in future. The two company will be like one company. Deep cooperation and resource integration will make you and your company powerful.

PC film is widely used for printing chart, pharmaceutical packaging, film type commutator.

Polycarbonate injection molding process

This is general polycarbonate injection molding process. During your polycarbonate injection molding, you should read your resin specification, your products and mold design from your polycarbonate molding supplier to set up the injection molding parameter. You can always find the the resin specification on IDES.com

Poly carbonate Drying Before molding	PC resins are hygroscopic and pre-drying is important. Recommended drying conditions are 100 – 120 C (212 – 248 F) for 3 to 4 hours. Moisture content must be less than 0.02% prior to processing.
Polycarbonate Molding Melt Temperature	260 – 340 C (500 – 644 F); higher range for low MFR resins and vice-versa
Mold Temperature For Polycarbonate Molding	70 – 120 C (158 – 248 F); higher range for low MFR resins and vice-versa, On the PC molding process, we should prepare hot oil supplies or hot water supplies for injection mold temperature control.
Fill Pressure	As high as possible for rapid molding
Injection Speed	Slow injection speeds when small or edge gates are used; high speeds for other types of gates

Steel choice for transparent polycarbonate injection mold

You should choose 420 series stainless steel for polycarbonate injection mold. There are lots of kind of 420 series stainless steel. If you need the surface finishing higher than SPI A3, you had better to choose the ASSAB S136 and NAK80. If it is SPI A3, you can choose LKM 420.  You can also see the injection mold steel post on our blog to know more for the mold steel choice.

Steel choice for opaque polycarbonate injection mold

You can choose the mold steel as the normal injection mold. Please be sure that you will not switch to have the transparent plastic molding products from this mold.  Please read more details for the mold steel choice based on mold life on post “plastic injection mold life“.

Thermoplastic injection molding

Thermoplastic injection molding

What is thermoplastic resin?

Thermoplastic resin is the plastic resin is soft after heating and hardened after cooling. Also the thermoplastic resin can be  recycling after injection molding. The thermoplastic resin is the most common plastic resin used for plastic injection molding and the plastic products used for our industry and life.

There are lots of thermoplastic resin as below:

What kind of products used the thermoplastic injection molding?

Thermoplastic molding cap

Thermoplastic injection molding cup

Most of injection molding plastic parts are used this process to make out such as plastic cups, plastic bottle, plastic caps, automotive plastic part(like handles, dashboard plastic part, automobile bumper and automotive seat plastic bracket etc.) , home appliance product plastic part, communicate plastic parts, cameras plastic parts, electronic and electric product plastic enclosure and accessories(like plastic fans, power supplier plastic enclosure, electric shaver plastic enclosure and plastic accessories, plastic socket and electricity meter plastic parts etc.)

Except for thermoplastic resin, is there any the other resin?

On the opposite side, it is the thermoset plastic resin. Normally this resin is solid and soft, and it is not possible to recycle.  The thermoset plastic resin hardened after heating. There are a few thermoset resin as following:

• Phenol-formaldehyde resin



• Bakelite



• Animoplastics



• Urea-formaldehyde resin



• Melamine-formaldehyde resin (MF)



• Melamine-phenol-formaldehyde resin (MPF)



• Epoxide resin



• Silicone (liquid or solid)

Normally these resin is to use injection molding or compression molding. On the injection molding process for this resin, there should be cooling near the runner and no heating on the injection machine barrel.
