Plastic injection moulds are usually made from hardened or pre-hardened steel, aluminium and/or beryllium copper alloys. Steel moulds cost more but are often favoured due to their high durability.

The advantages of China plastic injection moulding die focus on high precision and repeatability, speed, low cost per part and a large selection of available plastics. It is customisable. Disadvantages include higher initial costs and lead times than some other processes.

Plastic injection moulding processes can cost from US$3,000 to US$100,000 or more. Simple moulds typically cost between US$1,000 and US$5,000, while larger, more complex, high-volume or multi-cavity moulds can cost US$20,000 to US$60,000 or more.

The life span of a typical China plastic injection mould varies from a few hundred to over a million cycles. The lifespan of an injection mould depends on factors such as its environment, maintenance, construction, SPI classification and injection mould factory.

Plastic injection molds are used to produce plastic parts and products. The molten plastic is injected into the mold cavity, where it takes on the shape of the cavity. After the plastic cools and hardens, the mold can be opened and the part removed.

Plastic injection moulds are used to manufacture a wide range of products, from plastic household products and spectacles to automotive parts and toys. The versatility of the technology means that it can be used to produce small and large items with high precision. In addition, plastic injection moulding is a relatively quick process, which helps manufacturers keep up with the demand for their products.
