Plastics & Rubber Deflashing

Pioneering cryogenic deflashing innovations that help protect the environment while offering you more performance, more service, more expertise and more cost efficiencies

Parts moulded from plastics and rubber can be prone to the formation of flash. This can occur in the space between mould cavity edges, otherwise known as the parting line. This space or parting line could be the result of a number of factors, including complex part geometries (i.e. many mating surfaces), old mould cavities that no longer fit together tightly, stresses generated by the moulding tool (thermal, mechanical, etc.) or simply wear and tear on the tool.

Removing flash from moulded components

Traditional flash cleaning methods involve tedious and ineffective manual processes that rely on chemicals and handheld tools. Here at Linde, we have developed automated, non-abrasive and environmentally friendly solutions that effectively remove flash from plastic parts to consistently high quality standards. These are outlined below:

  • Cryogenic deflashing based on liquid nitrogen (LIN), using freezing, tumbling and blasting action to remove flash from injection-moulded plastic parts
  • CRYOCLEAN® snow using carbon dioxide particles (dry ice) at a temperature of -78.5°C as a blasting agent to deburr/deflash plastic parts
