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.

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.

Polycarbonate can be used for helmets, protective masks, sunglasses and sports goggles.

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“.
