THE GENERAL DESCRIPTION OF CRYOGENIC DEBURRING AND CRYOGENIC DEFLASHING TECHNOLOGY

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 deflashing:

• O-Rings (particularly suitable)
• Moulded Rubber parts
• Rubber-Metal Compounds
• Thermoplastics
• Zinc Pressure Cast

NANJING PEGE TECHNO MACHINE CO., LTD  provides cryogenic deflashing services that are both fast and cost-effective at removing residual flash created during the molding process.


COMMON QUESTIONS REGARDING THE NITROGEN DEFLASHING MACHINE

  • Who uses Cryogenic Deflashing?

NANJING PEGE provides cryogenic deflashing services to molders and OEM manufacturers that make injection molded, extrusion molded and compression molded parts.

  • What materials can we deflash?

Most rubbers, plastics, and composites have been successfully deflashed with cryogenic deflashing.

Common candidates include silicone rubber, FKM, EPDM, neoprene, LSR, fluorosilicones, ABS plastic, PEEK, Delrin and other acetals, nylon, PPS, HD/PEs, PEIs including Ultem, Vespel, polypropylene, zinc, and polycarbonate.

  • How do we deflash the parts?

We provide multiple methods to remove flash from molded parts. The location and intensity of the residual mold flash will determine which process is the most suitable.

Our Cryogenic Deflashing process utilizes gaseous nitrogen as a cryogen to freeze the parts while they are tumbled and blasted with plastic media. This cryogenic deflashing process is able to remove mold flash from difficult to reach areas including cross-holes, blind holes and other difficult geometries.
