Rubber Component Finishing Process

At Harkesh, 2 proven methods are inbuilt in the finishing process of rubber components, commonly also known as – Deflashing:

  • Tumbling in abrasion media
  • Cryogenic Deflashing

Tumbling

The product is placed inside a chamber which rotates at a high speed. The shape of the chamber helps the tumbling action within the enclosure. The chamber is filled in with the product, liquid and a suitable abrasion media in appropriate proportion. This method has been developed using in-house technology and desired results are obtained in a cost-effective manner.

Cryogenic Deflashing

The product is placed in a chamber with suitable media and is turned at a specific RPM. The temperature of the product is brought down to sub-zero level, using liquid Nitrogen. The chamber is fitted with squat impellers which help tumbling with media. The flash becomes brittle and is separated from the product. This method gives excellent results. The selection of this method is opted for depending on the part material, quantity and cost
