Ideal way to clean flashes of polyurethane bumpers or PU bumper for Automotive shock absorption

CRYOGENIC DEFLASHING/DEBURRING MACHINE APPLICATION ON THE POLYURETHANE BUMPERS DEBURRING PROCESS

Cryogenic deflashing/deburring machine is applied to deflash or remove the flashes of polyurethane bumpers for Automotive shock absorption.
We will explain how the cryogenic deflashing machine can efficiently remove the flashes of PU bumpers.

A.Processing Parameters Description

Cryogenic deflashing/deburring process has 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 0.8 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.

B. Part Description

Refer to the parts we receive, we think that it is suitable for the cryogenic deflashing machine as the material, size, shape are all Ok.

--Material is good and suitable for cryogenic deflashing

--Size is a little small, which is also Ok

--Flash condition is relatively good as it is flat and thin, most is less than our requirement 0.2mm.

 The processing result is relatively good according to our experience and inspection.
