What is Rapid Prototyping Injection Molding?

Injection molding is the rapid tooling technique by the infusion of plastic into the steel cavity mold which is a common use for making high-quality end parts production. It is the most efficient way to produce plastic parts in high volumes for commercial and functional using.


At Xin Pin, we offer machining and finishing services to make tools from a wide range of materials and can produce 50 to 100,000+ finished parts. With our material verification and quality processes, we can ensure your tools and parts are out of your expectations.


Specification of Rapid Injection Molding



Mold Material

Tool Steel P20, Carbon Steel S50C, Aluminium

Injection Mold Services Category

a. Rapid Tooling

Molds with steel cavity and core with a short life of 5,000-10,000 times which normally machined in 2 weeks.

b. Multi-calvity or Family Molds

Multiple identical cavities or family of parts machined into a single tool, Allows for more parts to be produced per shot, minimizing unit costs

c. Insert Molding

Inserts are placed into the mold and molding occurs around them to extend tool life for critical features. Allows for inserts such as helicoils to be molded in your design.

Standard Tolerance
