Why Do Plastic Injection Molds Cost So Much?

Plastic Injection Molds

People often ask why plastic injection molds cost so much? Here is the answer –

Producing high quality plastic parts can only be achieved by using a high quality built mold. Molds for plastic injection consist of precisely machined components made from various metals such as aircraft grade aluminum or hardened mold steels.

These molds are designed and made by highly skilled and well paid people categorically called “mold makers”. They have spent years and possibly even decades being trained in the mold making trade.

Additionally, mold makers need very expensive tools to perform their job, such as very expensive software, CNC machinery, tooling, and precision fixtures. The amount of time that mold makers need to finish a plastic injection mold can range from a few days to several weeks depending on the complexity and size of the end product.
