Rubber Mixing Process

Two types of rubber mixing processes are used at Harkesh. We are currently using in excess of 75 compound formulations and the process of development of new ones as per customer requirements is continuously on-going. Technical assistance with respect to compound development, production and testing is taken as per customer needs. The Synthetic Rubber elastomer, fillers like carbon black and other chemicals as per the formulation are weighed with a computer aided semi-automatic weighing system.

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.

Moulding Process

We choose the most well – suited technical method out of the 3 industry relevant options at Harkesh LLP:

✓ Automatic Injection Moulding
✓ Semi-automatic Vacuum Compression Moulding
✓ Compression Moulding

All the methods have their advantages and limitations. The choice is driven by the volume, nature of material, cost of raw material, required speed of production and the complexity of the product size/shape. The final aim of the process is to deliver the required quantity consistent with quality standards, thus creating value for the customers in mutually signed – off budget.
