FAQs

What is plastic injection molding?

Plastic injection molding is a manufacturing process in which molten plastic is injected into a mold cavity under high pressure to form a part. This process is ideal for high-volume production runs of identical parts.

How does the injection molding process work?

In injection molding, molten plastic is injected into a mold under high pressure. The plastic cools and solidifies, taking the shape of the mold. Once cooled, the part is ejected from the mold.

What industries use injection molding?

Injection molding is used across many industries, including automotive, medical devices, consumer products, electronics, and packaging.

What are the benefits of custom injection molding?

Custom injection molding offers several benefits, including the ability to create high-precision parts, cost-effective production for large runs, and flexibility in design for complex parts.

How long does it take to create a prototype using injection molding?

With rapid injection molding, prototypes can typically be created within a few days to a week, depending on the complexity of the design.
