Whether you’re developing a new product requiring flexible or elastomeric components or evaluating liquid injection molding partners, our team is here to help. Below are answers to common questions about our liquid injection molding capabilities and manufacturing process.
Liquid injection molding (LIM) is a manufacturing process that uses liquid silicone rubber (LSR) or other elastomeric materials injected into a mold cavity to produce flexible, durable, and precise components. It is commonly used for medical devices, seals, gaskets, and other demanding applications.
We primarily process liquid silicone rubber (LSR) and other elastomeric materials. Our team can help recommend the right material based on your application's performance, flexibility, and regulatory requirements.
Hi-Rel Plastics is certified to ISO 13485, ISO 9001:2015, and AS9100D, supporting medical, aerospace, defense, and other quality-critical manufacturing programs.
