Injection mold cost

Injection mold cost

Every customer would like to have reasonable injection mold cost and high quality injection mold.  Then how we can calculation plastic injection mold cost? First of all we should know what kind of cost include in the injection mold making and what will affect the injection mold cost.

What is injection mold cost?

• 
  
  

  Injection mold manufacturing

  
  

  Injection mold steel



• Injection mold base


• Injection mold manufacturing


• Injection mold trial resin


• Injection mold trial


• Injection mold design


• Injection mold transport


• Injection mold profit


• Core and cavity surface finishing


• Risky cost of injection mold manufacturing and mold trial


• Injection mold tax and Vat cost

What will affect the injection mold cost?

• Plastic product size and concept;  This is one of major factor to affect the injection mold cost as the mold size is depends on the plastic product size and plastic product structure.  For example, plastic product with under need to make mold with slider or  angle lifter will make the mold size bigger and more manufacturing process, and also increase the risky of the mold manufacturing and mold trial.


• Injection mold steel type;


• Plastic molding resin


• Injection mold life


• Injection mold base type


• Surface finishing of core and cavity


• Customers’ injection mold specification

Corrosive plastic resin such as PVC and POM etc request to have the anti-corrosion steel( stainless steel). Generally, the stainless mold steel is more expensive than the common steel.

The mold life is one of major factor to affect the injection mold cost too, you can review our post”injection mold type” to understand the details, different mold life request different injection mold steel, mold design and manufacturing process.

Why injection mold base type will affect the mold cost? It is very often for US and Europe customer to use the DME or HASCO standard mold base, that request the DME or HASCO standard guide system and mold base price is a little bit more expensive than China standard mold base even if we can custom the guide system in China local mold base supplier. Anyhow there are more and more China mold base supplier are willing to customize the DME and HASCO mold base, this will make the mold cost have less different by using standard or non-stand China mold base.

Why surface finishing of core and cavity affect injection mold cost?  The surface finishing of core cavity is also the surface finishing of plastic molding product such as texture and polishing. For example, if it is transparent plastic product mold, then it request stainless steel (AISI 420 or AISI 420ESR) and mirror polishing for the core and cavity, so there is more steel cost and polishing cost.

How can I control the injection mold cost if I am not professional for the injection mold technique?  Please do not worry about this, during the quotation process, Seasky Tooling will consider all of the factor of mold making and choose the most suitable and reasonable solution for customers based on customers’ request such as plastic products production demand, surface finishing, plastic resin and plastic product function etc.

The end we think it is very important to find most honesty and professional injection mold maker for your plastic injection mold making, then you can get reasonable and high quality mold with less work and risky.

How to reduce plastic mold making and plastic molding parts cost?

Plastic mold making and plastic molding cost control

Plastic mold making

1. On the plastic mold making process, to choose a most reasonable mold making process and make effective time line schedule for each mold making process is really good solution to reduce cost of  plastic mold making and plastic molding parts.

2. Sure quality control for each mold making process and every type of molds making is really important to reduce the cost of molds and production.

3. Choosing the best mold making process is another good solution to reduce the cost of plastic mold making and plastic molding parts too.

For example, if the demond of a big plastic molding cover which just have hollow feature is only 1000 parts, then we can choose the thermoforming process to make plastic molding parts.Thanks to the thermoforming technology,it is much more cheaper than plastic injection mold.

4. Sometimes, we can also consider to use the compression molding process to produce rubber parts to reduce the mold and rubber parts cost.

5. Choosing the proper steel for mold making based on different resin and demond of plastic molding parts is also very inportant thing to reduce the plastic mold making and plastic molding parts cost.  For example, if it is ABS molding parts, it’s not cost-effective to choose ASSAB S136 to make the core and cavity of injection mold, we can choose H13 or P20 steel instead.

There are also lots of solution to reduce the injection mold and injection molding cost such as optimizational mold design and  effective company management etc, but anyhow, any improvement or solution should be in the premise of quality assurance.

Seasky Tooling is not only able to offer the simple mold and production quotation, mold making and production, but also able to offer the most cost-effective solution to reduce the cost of plastic mold making and plastic molding parts.

Injection mold cooling

Injection mold cooling

Injection mold temperature

Injection mold temperature is critical in producing qualified plastic parts.

Part cooling and solidification

Mold temperature is critical in glossary and residue strain of plastic part.

Uniform mold temperature reduces the effects of warpage.

Commonly controlled by water, hot oil of hot water cooling channels.

Injection molding cooling

On the injection molding process, above information is very inportant to get qualified plastic parts, based on different resin, we can choose hot oil, hot water, water or cold water to control the injection mold temperature. Also we can use the different mold temperature to fine tune the warapage, reducing cycle time, gloss surface finishing and shrinkage as well as dimensions. Before the injection molding, we have to read the resin specification to have the suggested mold temperaturer and cycle time to prevent resin degradation. On the transparent polycarbonate injection molding, if the resin is degradated, the plastic parts will have yellow color, this also happen on the other resin, we should be easier to discover this issue on the transparent molding parts.

Injection mold cooling

Cooling: Amorphous Resin

Mold temperature determines cooling time and therefore degree of crystallinity

Cooling trough the crystallinization range too quickly will result in reduced crystallinity(Quenching)


Injection mold cooling

Plastic injection molding dark streaks solution

Plastic injection molding dark mark appearance

• Streaks ranging in color from dark to black.

Dark streaks caused by deposits of thermally damaged material from the hot runner

Plastic injection molding dark mark cause

• Processing using a screw which is too deeply flighted in the feed section (air intake)


• “Dead spots” in the plasticizing unit or hot runner system


• Defective nonreturn valve


• Screw decompression is too great or too fast


• See diesel effect

Plastic injection molding dark mark correction

• Raise temperature in feed section so that melting is earlier; use more suitable screw


• Check plasticizing unit and hot runner for zones of impeded flow and if necessary correct them


• Replace defective nonreturn valve


• Shorten the path for screw decompression or decompress a reduced rate


• Improve mold vent operation or design

Plastic injection mold venting system design and manufacturing

Plastic injection mold venting system design and manufacturing

What is injection mold  venting and why vent?

Mold venting is a process that is used to remove trapped air from the closed injection mold and volatile gas from the processed melting plastic. Without mold venting, the trapped air will compress as plastic tries to force it out of the mold and the air will ignite, burning the surrounding plastic and causing charred areas on the plastic molded part. Trapped air also keeps the plastic from filling in those areas of the mold cavity where the air is trapped so a non-filled (or short) part is molded. Volatile gases will be absorbed by the plastic and will cause voids, blisters, bubbles, and a variety of other defects.

 

Seasky Tooling plastic injection mold venting system design and manufacturing

 

Runner venting

1.  All of the end of the runner and runner slag have to be vented.


2. There should be enough venting for cavity; Also there should be venting at the opposite side of the gate, air trapped area and aftermost plastic resin flow.


3. To lead the venting on core pin and inserts out of injection mold.


4. Preferentially use grinding machine or EDM machine to manufacture venting.


5. Venting require as below, different resin with different venting depth.
