The moulded parts are placed in a perforated stainless-steel basket and inserted into a highly insulated blast chamber. Liquid nitrogen is injected into this chamber in which the basket with your moulded rubber parts is mechanically rotated to expose all parts to the blast media. Liquid nitrogen lowers the temperature (some cases up to -130°C) while freezing the rubber to make it brittle. A unique high-speed (up to 7,000 rpm) impeller directs and throws plastic shots at the tumbling parts into the rotating basket. Travelling at high-speed, these small pellets cleanly trim off the brittle flash leaving a high quality, flash less molding. The machine separates reusable media from debris (flash and dust).Parts that have thin flash can be quickly and thoroughly cryogenic deflashed.

Operation Process of the cryogenic deburring
Step A: After precooling the machine inner chamber, set the parameter on the touch screen which is suitable for the parts to be processed.
Step B: Use a barrel to contain the moulded parts first and then put into the machine basket and close the door.
Step C: Press the cycle start button on the touch screen to let the moulded parts to be processed automatically.
Step D: When one cycle is finished, press the cycle stop to stop running and take out the finished parts which are successfully trimmed. And then start another cycle.
Parameter Setting Principle
Six main parameters, temperature, wheel speed, barrel speed, and processing time, media size and quantity
Temperature: The cooling temperature to freeze the flashes
Wheel speed: Decide the power shot on the flashes with media
Barrel speed: The tumbling speed of the barrel to keep all the parts be blasted.
Processing time: Processing time depends on the processing result and quantity of the parts.
Media size: 0.5 0.75 1.0 1.2 and 1.5mm, each one has different power.
Quantity: The number of parts can be processed
We always use these 6 parameters to describe the right processing parameter and adjust gradually to find a best one.
