In rubber parts production, deflashing is key to product appearance and sealing performance. For EPDM rubber parts (such as seals, bumpers, grommets, and tube plugs), the material’s high elasticity and durability often cause problems with manual or mechanical deflashing, like uneven cuts, wrong sizes, or cracks. Cryogenic deflashing uses low temperatures to make flashes brittle, making it the best choice for complex EPDM parts.
As a professional maker of cryogenic deflashing machines, STMC not only builds multi-model liquid nitrogen deflashing machines, but also offers cryogenic deflashing services. This helps small-batch orders, trial production, or factories without their own equipment get high-quality deflashing at a lower cost.
Technical Advantage: Precise Temperature Control, No Damage
STMC uses advanced cryogenic deflashing. Liquid nitrogen cools EPDM parts to below their glass transition temperature (usually -50°C to -80°C). This makes thin flashes brittle while the main part stays unchanged. Then, high-speed media blasts the parts, making the brittle flashes fall off without harming the part. This method works for flashes, mold lines, and excess material from molding, injection, or extrusion. It is especially good for parts with holes, grooves, or odd shapes.

When to Use This Service
-
EPDM parts for cars, electrical seals, building waterproofing, or industrial dampening
-
Small batches with many different parts – high manual deflashing cost
-
Trial mold samples – need quick mold testing
-
Busy season capacity limits – temporary need for outside deflashing help
