Runnerless Molding: improving silicone part integrity while reducing waste

Runnerless Molding using silicone rubber requires a carefully coordinated control of temperature, pressure, seam tolerance, injection time, and cure time. Dymotek excels at controlling all these variables through a special design and air-control process that produces runnerless or bracket-free molded parts. This procedure offers you significant cost-savings because it eliminates the excess bracket or runner which is often created through conventional material injection methods—eliminating waste and utilizing virtually 100% of the costly raw LSR (Liquid Silicone Rubber) material.

By creating your silicone parts through runnerless molding, we also eliminate the time and resources that would be needed for bracket removal. Finally, our runnerless molding process greatly improves on part quality and accuracy by delivering a mold-perfect finish that’s free of the imperfections and variables common with runner-attached parts.
