General Information
Barwell Freeze Trim machines are all designed and built to meet the most exacting demands of the industry. We have facilitated high productivity with a significant reduction in operational costs. Our systems are versatile, encompassing the needs to deflash a wide range of material and sizes.
Able to process a wide range of materials and available in a range of sizes, these compact units achieve fast process times and help to significantly reduce the operational costs involved in moulded product deflashing.
Incorporating the latest PLC controls coupled with a touch screen operator interface simplifies the whole deflashing process. A product database for thousands of part set-ups allows quick and easy operation when changing from one part to another
Fully enclosed construction and a patented media assist ensures minimal usage of liquid nitrogen and media.
How it works
Rubber and plastic parts are placed in a stainless steel parts basket, which rotates in a blast chamber evenly exposing all parts to the blast media. The chamber is insulated with rigid polyurethane foam to ensure stable temperatures.
Liquid nitrogen lowers the interior temperature, freezing the flashing to make it brittle. Use of high-purity, moisture-free nitrogen eliminated the need for a dryer and prevents part contamination due to moisture.
The high-speed impeller shoots polycarbonate plastic pellets into the chamber. Traveling at high speeds, these pellets cleanly trim off the inner and outer diameter flashing of parts in one operation.
The unit is fully enclosed to minimize ambient noise levels. Blast media and flash can be separated and recovered for reuse.
