Quality Standards for Automotive Rubber Parts
ISO 9001 certified. ASTM D2000 tested. PPAP documented. Every part, every batch, guaranteed.
At Vertex Rubber India, quality is not just a department — it's the foundation of everything we do. As a leading automotive rubber manufacturer, we understand that the performance and safety of our automotive rubber components directly impact our clients' products and reputation. That's why we maintain one of the most rigorous quality management systems in the Indian rubber manufacturing industry.
Our quality system is built on three pillars: ISO 9001 certified processes, ASTM D2000 material testing standards, and complete batch traceability. Every automotive rubber part that leaves our factory has been inspected, tested, and documented.
Our quality management system is ISO 9001:2015 certified, ensuring consistent processes, continuous improvement, and customer focus across all operations.
All material compounds are tested to ASTM D2000 standard classification for automotive rubber applications — the internationally recognized standard for rubber material properties.
For OEM clients requiring Production Part Approval Process documentation, we provide PPAP Level 3 packages including design records, FMEA, control plans, and capability studies.
Statistical Process Control (SPC) is implemented across critical production parameters — cure time, temperature, pressure, and finished dimensions — ensuring consistent quality.
Our in-house material testing laboratory is equipped with advanced testing equipment to verify every rubber compound before production begins. Key tests performed:
| Test | Equipment | Standard | Frequency |
|---|---|---|---|
| Shore A Hardness | Durometer | ASTM D2240 | Every batch |
| Tensile Strength & Elongation | Universal Testing Machine | ASTM D412 | Every batch |
| Compression Set | Compression Set Fixture | ASTM D395 | Every batch |
| Tear Strength | Trouser Tear / Angle Tear | ASTM D624 | Every batch |
| Specific Gravity | Density Balance | ASTM D297 | Every batch |
| Heat Ageing | Aging Oven | ASTM D573 | Every batch |
| Oil Resistance | Immersion Test | ASTM D471 | Quarterly |
| Ozone Resistance | Ozone Chamber | ASTM D1149 | Quarterly |
Every production batch undergoes rigorous dimensional inspection to ensure all automotive rubber parts meet the specified tolerances. Our inspection equipment includes:
All raw rubber, chemicals, and metal inserts are inspected against specification before acceptance. Certificate of Analysis is verified for each shipment.
During production, operators conduct regular checks on critical dimensions, appearance, and hardness. Process parameters are monitored and recorded in real-time.
For every new production run, the first piece is thoroughly inspected for all dimensions, material properties, and visual requirements before production proceeds.
Finished parts undergo 100% visual inspection plus AQL-based sampling for dimensional and physical testing. Only parts meeting all specifications are approved for dispatch.
Each shipment is accompanied by a Material Test Certificate (MTC) documenting batch numbers, material properties, dimensional results, and quality approvals.
