Plastic Injection Molding

Injection Mold Service

At Bohao Prototyping, we specialize in producing high-quality plastic injection molded parts and mold tools. We offer machining and finishing services to make tools from a variety of materials, and can produce 50 to 100,000+ finished parts in a wide variety of plastics. With advanced material verification and quality processes we can ensure your tools and parts exceed your expectations.

What is Injection Mold?

Plastic injection molding is by far the most common way to produce large volumes of finished plastic parts for every kind of commercial and industrial use. Molten resin is injected under high pressure into the cavity of a metal die and then rapidly cooled, forming a solid shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.

Advantages of plastic injection molding

  • Thousands of plastic materials to choose from

  • Make large volumes fast

  • Stable and reliable process

  • Excellent surface quality

  • Overmolding for more design options

  • Tools can last up to millions of cycles

Which resin to use for plastic injection molding?

Multiple materials can be used for plastic injection molding.  PMMA, ABS, PP, PC, HIPS, LDPE are usually be used, we also can use other special materials. Contact our engineer to have your plastic injection molding project review.

Tooling for Injection Molding

In Bohao we use aluminum 7075, pre-hardened tool steels (for example, P20 and NAK-80) to manufacture moulds.
