How We Manufacture Rubber Components of All Sizes
When you think of rubber components, the first thing that might come to mind is a small O-ring or gasket. But at Harkesh Rubber LLP, from micro-precision parts to large-diameter seals, our manufacturing capabilities are designed to deliver reliability, performance, and consistency.
Here’s a peek into how we make it happen.
1. Understanding the Requirement
Every project starts with understanding the application, environment, and performance expectations.
Small parts often require high precision for sealing, insulation, or vibration damping.
Large parts may need strength, flexibility, and resistance to extreme conditions such as high pressure, temperature variations, or chemical exposure.
Our engineering team works closely with clients to select the right material and design, ensuring every dimension and property is fit for purpose.
2. Material Selection & Formulation
We work with a wide range of polymers, from Nitrile (NBR) and EPDM to Fluoroelastomers (FKM) and Silicone, customizing compounds to meet specific industry standards.
For sub-zero applications, we develop low-temperature resistant compounds.
For high-performance environments, we use heat- and chemical-resistant blends.
Our in-house compounding ensures consistent quality from batch to batch.
3. Precision Moulding
Whether the component is small or large, the moulding process is critical:
Micro & small components: Manufactured using compression, transfer, or injection moulding, with tight tolerances and minimal flash.
Large components: Produced with careful temperature and pressure control to ensure uniform curing.
4. Finishing & Quality Checks
Post-moulding, each part undergoes specialized finishing:
Cryogenic deflashing for small components to remove micro burrs without affecting dimensions.
Manual trimming & inspection for large components to maintain edge integrity.
We use automatic visual inspection machines for precision parts and rigorous manual checks for bigger components.
