Rubber deflashing is the process of removing excess rubber known as flash from the surfaces and edges of molded parts. During rubber injection molding, flash is caused by parting line mismatches, improper venting, inadequate clamping pressure, excessively low viscosity, or poor sprue bushing support. Tooling and processing issues can also cause mold flash during injection […]

Why Medical Injection Molding Uses Cryogenic Deflashing
Medical injection molding supports the use of a wide variety of plastic and rubber materials. Examples include PEEK, polycarbonate, and LSR – just to name a few. During the injection molding process, excess material known as flash can escape the mold and mar part surfaces. The causes of flash are numerous and include parting line […]
The Five T’s of Cryogenic Deflashing Molded Parts
The Cryogenic Deflashing Process Cryogenic Deflashing is a process designed to remove molding flash created during the molding process. Molding flash can be found on molded parts along the parting lines, gate vestiges, and where pins and slides are located. In order for molded parts to complete their desired function, the residual molding flash needs […]
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 Rubber Parts
Cryogenic deflashing removes flash, a type of surface defect, from molded rubber and molded plastic parts. This computer-controlled batch process provides faster cycle times, reduced labor costs, and greater part-to-part consistency than hand trimming.
