Design Tip: Cutting corners on injection-molded parts

Proper placement of corner radii and fillets in injection molding design creates strong, high-quality, cost-effective plastic parts. Sharp corners have their place. Without them, we wouldn’t have triangles, all birthday cakes would be round, and it’d be darned tough to scrape a piece of gum off your shoe. But sharp corners can spell trouble when injection molding plastic parts, and product designers …

Rubber Molding Guide

Organic Rubber Injection. Organic rubber injection starts with more efficient material preparation. The material is mixed, and then stripped into continuous strips and fed into a screw which charges a barrel as needed with a pre-defined amount of material. When the mold is closed, the material in the barrel is injected into the mold cavities and cured. Benefits of injection molding include:

Rubber Injection Molding & Molded Rubber | Molding Process

The process of injection and injection-transfer molding starts with efficient material preparation. To begin, the material is mixed in bulk and then stripped immediately into continuous approx. 1.25" wide & .375" strips. These strips are then fed into a screw which, in turn, fills a barrel with the appropriate predetermined amount of rubber material.
