Medical Injection Molding and Flash Removal

Medical injection molding can produce complex and highly-precise components with part-to-part integrity across high production volumes. Whether the material is plastic, silicone, or another polymer or elastomer, medical injection molders need to avoid warping, sink marks, short shots, and residual stresses that can cause defects. Molders also want to minimize flash or flashing, excess material […]

Case Study: Cryogenic Deflashing for Silicone O-Rings

Nitrofreeze® Cryogenic Deflashing provides part molders and OEM manufacturers with a fast, consistent, and cost-effective way to remove flash from silicone O-rings. Cryogenic deflashing uses gaseous nitrogen to freeze the parts, and plastic media to break-off the surface imperfections. This safe, clean process removes both outer diameter (OD) and inner diameter (ID) flash so that […]

What Is Residual Mold Flash? Flash is excess plastic or rubber material that forms on the surface of molded parts. Flash, or flashing, affects the part’s surface finish and may also interfere with sealing. Flash is usually a cosmetic defect, but molders want to avoid the appearance of thin, unwanted lines that can suggest poor […]
