Precision Plastics for Mission Critical Parts

High-performance injection molding demands a scientific approach. We use Scientific Injection Molding (SIM) to ensure every part meets the strictest standards for precision, repeatability, and compliance. Whether you’re manufacturing medical devices, aerospace components, or critical industrial parts, our data-driven process eliminates variation and maximizes quality.

Our overmolding process allows us to combine multiple materials into a single component, enhancing functionality and performance. This process is ideal for creating ergonomic designs and improving the durability of parts. We use cutting-edge technology to ensure a seamless bond between materials, resulting in superior end products.

Insert molding integrates metal or plastic inserts into the molded parts during the injection process. This technique enhances the strength and functionality of components, making it perfect for complex assemblies. Our expertise in insert molding allows us to produce parts with embedded reinforcements, electrical components, or threaded inserts with precision.

We offer specialized medical molding services to produce high-precision, sterile components for the healthcare industry. Our Class 8 Clean Room ensures that all medical parts are manufactured in a controlled, contamination-free environment. This guarantees the highest standards of cleanliness and compliance with medical regulations.

Micro injection molding is a technique for producing tiny and precise components using minimal resin volumes in the injection procedure. Our expertise in micro injection molding allows us to create intricate parts with high accuracy, perfect for industries such as medical devices, electronics, and automotive components.
