Raw Material Inspection
All incoming materials are inspected to verify material grade, mechanical properties, and suitability for pin manufacturing before production.
Dimensional Accuracy Inspection
Advanced measuring equipment is used to check critical dimensions, including diameter, length, tolerance, and geometric accuracy, ensuring consistent product performance.
Surface Quality Inspection
Each dowel pin is inspected for surface finish, machining quality, and appearance to ensure smooth fitting and reliable assembly performance.
Final Inspection Before Shipment
Finished products undergo final quality checks before delivery. Inspection records and batch control procedures help ensure product consistency and traceability for every order.
Precision Dowel Pin Manufacturing Process
Our Dowel Pins are produced through a controlled multi-stage process to maintain the required geometry and mechanical properties.
- Material Cutting
Alloy steel or specified raw material is cut according to the required blank length, with material specifications confirmed before further processing.
- Heat Treatment
Pins undergo the specified hardening process to achieve the required hardness and mechanical condition while maintaining dimensional stability.
- Precision Grinding
The hardened blanks are precision-ground to the required diameter and cylindrical geometry, providing the dimensional condition required for accurate mating-hole assembly.
- Surface Treatment
After grinding, the pins can receive the specified surface treatment or protective finish according to the application and customer requirements.
FAQ
