Injection mold cost estimation

  • Part size——large parts require larger mold sizes, so injection mold steel cost is higher.

  • Part material——the part material selection also influences the injection mold cost, if the plastic is corrosive such as PVC then stainless steel will be required to avoid the cavity from damage, and the price is high.

  • Part finish requirement——if the part has a high gloss surface requirement, take the auto light cover, for example, S136 steel and careful polish technical are required, injection mold will be expensive.

  • Production volume——high volumes will require multiple cavities so the mold size is bigger. High volume requires a mold that runs in the long term, so high-quality steel is required which increases the injection mold cost.

  • Country of manufacture——labor cost is different in different counties, countries with lower labor costs are able to make an injection mold at a lower cost, injection mold price in China is about 60% of the price in western countries.
