Engineering & Drawing Analysis

Review customer requirements, with 2D and 3D file,checkBOM,structure and critical notes, process documentation.
What we deliver: Complete drawings, BOM, and work instructions – all reviewed for manufacturability before production starts.

Precision Cutting & Stripping

Cut wires to exact lengths and strip both ends using high-precision automatic equipment.
What we deliver: Length tolerance within ±0.5mm, clean cuts, no nicked or broken conductors – every time.

Terminal Crimping

Permanently attach terminals to wire ends using precision crimping tools, creating reliable electrical and mechanical connections.
What we deliver: Crimp height and width per specification, pull force tested and verified, no deformation or damage.

Assembly & Routing

Route, bundle, and secure each branch according to the assembly board (built to your drawing specifications), and install protective materials like corrugated tubing or heat shrink.
What we deliver: Consistent branch routing, correct outlet positions, and a clean, twist-free harness that matches your design.

Quality inspection,100% Electrical Testing

Test every single harness for continuity, insulation resistance, and dielectric strength before it leaves our production line.
What we deliver: Continuity ≤0.1Ω, insulation resistance up to spec, and no breakdown under hi-pot test – guaranteed.

Packaging & Shipping

Package products according to their characteristics (ESD bags, inner boxes, custom trays, etc.), verify quantities and labels, and prepare for shipment.
What we deliver: Secure packaging, clear labeling, and products that arrive at your line in perfect condition – ready to install.
