Quality Isn’t a Final Step.
It’s Built Into Every Step.
For tier-1 automotive assemblers, bearing manufacturers, and aerospace suppliers, material consistency is non-negotiable. At Priya Industries, every meter of wool felt is governed by strict German DIN and American ASTM protocols.
The Zero-Defect Quality Cycle
Raw Wool Purity & Micron Grading
Every raw wool consignment is inspected for staple length, crimp elasticity, and vegetal purity before entering the carding line.
Continuous Density Monitoring
Sensors on our hydraulic pressing and steam lines verify web compaction every 30 seconds to prevent thickness drift.
100% Optical Caliper Stamping Audit
Precision die-cut washers, gaskets, and slit rolls are inspected under digital optical calipers for dimensional tolerance within ±0.2mm.
Lab Mechanical & Chemical Testing
Destructive and non-destructive testing for tensile strength, elongation recovery, oil wicking rate, and pH neutrality.
Certificate of Analysis (CoA) Signoff
Our quality head signs off a dedicated batch test certificate detailing specific density, thickness, and ash content for every dispatch.
Barcoded Traceability & Barrier Packaging
Every crated roll or component box is barcoded for lot traceability from raw shearing farm to client receiving dock.
Internationally Certified Laboratory Standards
We maintain full laboratory equipment to test density, compression recovery, tensile break load, oil retention, and chemical neutrality before releasing any shipment.
German Technical Felt Standards
Defines wool percentage, density classification (F1 through F55), hardness, and permissible moisture content for engineering felts.
American Standard Test Methods for Wool Felt
Specifies tensile breaking load, thickness under specified pressure foot, oil absorption capacity, and chemical resistance.
Automotive Felt Specifications
Standards for anti-rattle NVH pads, bearing lubrication seals, flammability limits, and dust exclusion gaskets in motor vehicles.
Indian Technical Felt Specifications
Comprehensive guidelines for raw wool blending, chemical testing, density classification, and tensile strength standards.
