Technology / product information

Precision machining of pins for cable connectors. High-difficulty processing for small-diameter, deep-hole, and slit crimping pins, provided with Japanese-quality standards from Vietnam.
Overview
This product line consists of precision connector pins used for assembly into cable harnesses and connectors. They are small-diameter pins with deep holes along their length, making them prone to deformation, cracking, or vibration. This requires advanced precision machining technology and strict quality control. Additionally, when the pins require a slit at the tip for crimping, the process is fully handled from CNC machining to end processing, quality inspection, and mass production.
Features
- Supports high-precision machining for φ1.5–φ3mm long pins with deep holes
- Compatible with high-conductivity materials for connectors, such as brass and phosphor bronze
- Slit cutting and crimping allow for press-fit applications
- Systems in place to remove chips and burrs from horizontal and vertical holes
- Long-term repeat order track record: high-reliability parts with over 10 years of continuous supply
- Gold plating available; stable supply ensured through process-by-process quality control
