Product Description

Precision Hinge Pin | Anti-Noise & Anti-Loosening Special Solution

Taiyuanfeng - Custom Rivet & Pin Expert

Case

The customer procured a pin with an outer diameter tolerance of +0 to -0.012mm for use in hinges. Feedback on the current product includes:
1. Two end faces are not fully formed;
2. Surface indentations are present;
3. After assembly, the hinge exhibits abnormal noise, wobbling, or imbalance.
 
Core Problem Solved
Q:Still troubled by hinge jamming/noise/loosening even with standard outer diameter tolerance (+0~0.012mm)?
A:This is often due to a recessed end face or excessive surface roughness.

Solution

We can consistently maintain surface roughness at Ra ≤ 0.3μm, ensuring zero-failure operation of the pins during automated assembly.
 
Specific Approach
1. We select 45# carbon steel material, subjecting the raw material to two-stage wire drawing to achieve a smoother and more uniform surface finish;
2. After cold heading, we inspect product concentricity and employ core-less grinding to further enhance surface roughness to within Ra 0.3μm;
3. Optical sorting machines ensure a product qualification rate exceeding 99.99%.

Through our process improvements, we have enhanced our customers' yield rates and production efficiency, reduced assembly losses by 15%, and improved the switching feel and service life of finished hinges.
