Capabilities
How we make rubber parts at our factory in New GIDC, Gundlav, Valsad: from the sample mould and the compound to the checked, finished part.
Our capabilities
In-house tool room
Sample moulds for new parts are made in our own tool room, which can shorten development time where the part allows.
In-house laboratory
Compounds and moulded parts are checked in our own laboratory, which helps us hold strict quality standards from batch to batch.
In-house compounding
Rubber compounds are mixed in-house and matched to the job the part has to do.
Mould design
Moulds are designed for each new part, from your drawing or from a sample.
Reverse engineering
Worn or imported parts with no drawing are measured and remade to match.
Rubber bonded to metal
Rubber moulded onto metal, wood or engineering plastics, so the two work as one part.
Fabric-reinforced parts
Fabric-reinforced rubber for parts that must hold shape under pressure or load, such as diaphragms and liner rings.
Material selection support
Technical help choosing the right rubber for the medium, temperature and movement.
Choosing a rubber compound
The right compound depends on three things: what the part touches, the temperature it works at, and whether it moves or stays still. Tell us those with your enquiry and we will recommend the compound.
| Code | Compound | Typical range | Typically chosen for | Avoid with |
|---|---|---|---|---|
| NR | Natural rubber | −50 to +80 °C | Elasticity, tear and abrasion resistance, vibration damping | Oil, fuel, sunlight and ozone |
| NBR | Nitrile | −30 to +100 °C | Mineral oil, fuel, grease, water | Sunlight and ozone, brake fluid |
| EPDM | Ethylene propylene | −40 to +130 °C | Water, steam, weather, ozone, brake fluid | Mineral oil and fuel |
| VMQ | Silicone | −55 to +200 °C | Heat and cold, lighting fittings, static seals | Abrasion, tearing, high-pressure dynamic seals |
| CR | Neoprene | −35 to +100 °C | Moderate oil plus outdoor weather | Strong acids, fuels |
| FKM | Fluoroelastomer | −20 to +200 °C | Hot oil, fuel, many chemicals | Hot water and steam, ketones |
| FFKM | Perfluoroelastomer | −15 to +300 °C | Aggressive chemicals at high temperature | Cost-sensitive general duty |
| PU | Polyurethane | −30 to +80 °C | Abrasion and cut resistance, high load | Hot water and steam, strong acids |
Ranges are typical values for each family of compounds, not test data for a specific grade. The limits for your part depend on the grade chosen and are confirmed with the quotation. FKM is the generic name for fluoroelastomers.
1 · What it touches
Oil and fuel point to NBR or FKM. Water, steam and weather point to EPDM. Aggressive chemicals point to FKM or FFKM.
2 · How hot or cold
Silicone covers the widest range of temperatures. FKM and FFKM take high heat with oil and chemicals.
3 · Moving or still
Seals that move need tear and wear resistance, so silicone suits static seals better than moving ones.
From drawing to production
Drawing or sample
Your drawing, an old part or a photo with sizes.
Material selection
Compound chosen for what the part touches, the heat and the movement.
Tooling
Sample mould made in our own tool room.
Moulding
Parts moulded, and bonded to metal or fabric where needed.
Inspection
Compound and parts checked in our own laboratory.
Production
Approved sample first, then repeat batches.
