Batch Deflashing to Remove Mold Flashing We often hear from molders and OEMs that they have mold flashing after their injection molded plastic and rubber parts are manufactured. There are many ways for mold flashing to form on your parts during the injection molding process. Surfaces where sliding and moving parts meet will wear with […]

Sick & Tired of Paying for Issues from Hand Trimming?
Are you sick and tired of paying for quality issues caused by hand deflashing? We hear it all the time. You have a section in your manufacturing operation with a team of deflashing personnel sitting around a table. Your team may have seasoned veterans, but you still end up with a varying degree of flash […]
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 […]
Rubber Deflashing for Molded Parts: Nitrofreeze® Cryogenic Technology
Rubber deflashing is the process of removing excess material called flash, or flashing, from the surfaces of molded rubber parts. The causes of flash are numerous and include parting line mismatches, improper venting, inadequate clamping pressure, poor sprue bushing support, and excessively low viscosity. No matter what the cause, old or worn tooling is often […]
Cryogenic Deflashing for Medical Silicone Parts
Medical silicones can be molded into parts such as distal handles for surgical instruments and dental tools. There are many types of silicone rubber, but medical grade silicones need to meet biocompatibility requirements such as USP Class VI or ISO 10993. Then, after they are molded, medical silicone parts need to have a finish that’s […]
