Injection Molding
Processes
Make the move from prototyping to on-demand manufacturing for affordable, high-quality molded parts within days. Better yet, your prototyping tool is free once you shift to an on-demand manufacturing tool.

Plastic injection Molding
Our plastic injection molding service delivers high-precision,durable parts for both low and high-volume production.With a wide selection of materials and advanced molding techniques, we ensure efficiency and consistency across industries.

Silicone Rubber InjectionMolding
Ldeal for flexible, heat-resistant,and durable components, our silicone rubber injection molding process produces high-quality parts within two weeks. Perfect for medical, food-grade, and sealing applications, it guarantees superior elasticity and longevity.

Insert Molding
Insert molding enhances part strength by integrating metal or other materials directly into plastic components.This method is ideal for electrical connectors,automotive parts, and structural applications requiring superior durability and performance.

Over Molding
By bonding multiple materials together, our over molding process improves grip, durability, and aesthetics. lt's perfect for soft touch handles, protective casings and multi-material assemblies, enhancing both functionality and user experience
