Mixing Process

The most critical process in rubber product manufacturing is mixing process. Diatax has got the strong know-how on formulations & Mixing Technology which is acquired by the company over a period of time

The batches for mixing the Raw Materials are weighed electronically so that precise quantities are supplied for mixing. Our company uses Dispersion Kneader and Mixing Mills to ensure, the required quality of the rubber compound, to be used in the manufacturing process.

The mixing is done at controlled temperature. The next step is done after a set ageing time in which the mass of raw compound is again rolled with curing agents (accelerators). This compound is then moved through rollers to give sheets of desired thickness.

The compound is then tested in the laboratory for various routine type tests depending on the specifications. A few of examples are hardness tests, rheological tests, compression set tests, ageing tests in air and various other media.

Moulding And Finishing Process

At Diatax We have complete range of moulding technology –

  • Automatic Rubber Injection Moulding
  • Rubber Transfer moulding
  • Vacuum compression moulding.

Special controlled processes are developed by Diatax to produce such high performance critical products.

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

  • Tumbling in abrasion media
  • Cryogenic Deflashing

DIatax Aims to be the partner of choice for the supply of high quality precision moulded rubber products. to ensure we achieve our aim we constantly review our manufacturing and quality processes whilst developing new and enhanced formulations.

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.


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
