Our Quality Assurance Philosophy
We believe that quality should never be compromised. From raw material selection to final packaging, every step in our manufacturing process undergoes rigorous checks to ensure that our cotter pins perform flawlessly in critical applications.
Stages of Our Quality Control Process
1. Raw Material Inspection
We source high-grade steel and stainless steel from trusted suppliers.
Every batch of raw material is tested for chemical composition, tensile strength, and hardness before production begins.
Only materials that meet standards are approved for manufacturing.
2. Precision Manufacturing & In-Process Checks
Our state-of-the-art machinery ensures consistent dimensions and tolerances as per customer specifications.
Automated machines and precision tools guarantee uniformity in every cotter pin.
In-line inspections are conducted at multiple stages to detect any deviations early.
3. Dimensional & Mechanical Testing
Each cotter pin undergoes dimensional verification using calibrated micrometers, gauges, and optical comparators.
Hardness testing (Rockwell & Vickers) ensures durability and resistance to wear.
Shear strength and load-bearing tests confirm that our pins can withstand extreme mechanical stress.
4. Surface Treatment & Corrosion Resistance
We offer zinc plating, galvanization, and passivation for enhanced corrosion resistance.
Deburring and smooth finishing eliminate sharp edges, ensuring safe handling.
5. Final Inspection & Batch Testing
Before dispatch, a final 100% inspection is conducted.
Random sample testing from each production lot ensures batch consistency.
Traceability is maintained with heat codes and inspection records for accountability.
6. Packaging & Delivery Standards
Cotter pins are packed in corrosion-resistant packaging to prevent damage during transit.
Barcoding and labeling ensure proper identification and easy tracking.
