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 […]

Dry Ice Deflashing vs. Cryogenic Deflashing

What’s the difference between dry ice deflashing vs. cryogenic deflashing? Both are used to remove mold flash from plastic or rubber parts. Dry ice deflashing uses compressed air to propel a stream of solid carbon dioxide (dry ice) particles that blast away surface defects. Cryogenic deflashing uses gaseous nitrogen to freeze parts so that mold […]

Cryogenic Deflashing for Molded Parts

Cryogenic deflashing for molded parts removes mold flash from hard-to-reach areas such as cross-holes, blind holes, and other difficult geometries. During the plastic or rubber molding process, flash or flashing can occur anywhere that metal meets metal – especially as mold tooling wears. Plastic and rubber molders can remove these surface defects through hand or […]
