模压制品最高效的去边工艺-冷冻去毛刺系统

Most efficient deburring method for Moulded Parts-Cryogenic Deburring Machine 



The process of Cryogenic deflashing：

Low temperature liquid nitrogen will be injected in spraying mist on the moulded parts. During the conversion from liquid to gas state the extracted energy causes freezing of the burrs reaching the embrittled condition as fast as possible. The actual molded parts are much thicker and will still remain elastic and not frozen. 

The moulded parts are loaded in a barrel which will tumble itself during the process in order to ensure all parts can be blasted by suitable small size polycarbonate media.

The shock frozen burr is not as solid as the actual moulded part as it like thin glass, therefore it can now be removed by blasting media with high efficiency.

Any damage to the surface by flaking off due to the tension will be avoided.

This cryogenic deflashing process is able to remove mold flash from difficult to reach areas including cross-holes, blind holes and other difficult geometries.

Parts recommended for Cryogenic deflashing:

• O-Rings (particularly suitable)
• Moulded Rubber parts
• Rubber-Metal Compounds
• Thermoplastics including PA+GF PC+GF, PPS, POM, PBT and PEEK PTFE
• Thermalelastomer like PU,TPU, TPE and TPR
• Zinc Pressure Cast
