Quality
Excellence in Every Product — Driven by Quality
At KD Polytech Manufacturing LLP, quality is not just a process — it’s our promise.
Every hose, belt, and assembly we produce undergoes strict testing and inspection to meet international and Indian automotive standards.
Quality you can Trust
Our Commitment to Quality
We at KD Polytech follow a robust quality management system that ensures reliability, consistency, and performance in every product we manufacture.
- All raw materials and compounds are tested in-house before production.
- Finished goods — hoses, assemblies, and belts — are validated as per OEM and BIS/SAE/DIN standards.
- Continuous improvement through R&D and material innovation.
- All testing is carried out using NABL-approved test equipment under Indian Quality Standards.
- Every product batch carries a traceable quality record.

End-to-End Quality Process
Raw Material Testing
• Dimensional checks during extrusion and curing. • Adhesion and surface finish validation.
In-Process Quality Check
• Dimensional checks during extrusion and curing. • Adhesion and surface finish validation.
Final Product Testing
• Each batch of hoses, assemblies, and belts is tested under real-world simulated conditions. • Only after passing all tests do products move to packing and dispatch.
Advanced Testing Infrastructure
Our in-house laboratory is equipped with modern instruments for physical, chemical, and performance testing.
All machines are NABL-approved and calibrated to ISO & BIS standards
