Precision CNC milling + professional metal welded sheet fabrication under one roof. From prototypes to production runs, we deliver tight tolerances, complex geometries, and strong structural integrity. Request your custom quote today.

We provide custom CNC milling and precision metal welded sheet fabrication services for industries ranging from automotive, robotics, medical devices, to industrial equipment. Whether you need milled components from solid blocks or welded sheet metal assemblies, our facility is equipped to handle your most demanding designs.

With advanced 3axis / 4axis / 5axis CNC milling centers and a dedicated sheet metal workshop (laser cutting, bending, welding, post-processing), we deliver parts that meet ISO 2768-fine or even tighter tolerances. Our welding capabilities include MIG, TIG, and spot welding for carbon steel, stainless steel, aluminum, and alloys.

Key Features & Benefits
High Precision CNC Milling
Achieve ±0.005 mm accuracy. Complex contours, deep cavities, and micro features are no problem. We work with over 30 materials including aluminum 6061/7075, stainless steel 304/316, brass, copper, titanium, and engineering plastics.

Professional Welded Sheet Fabrication
From simple brackets to fully welded enclosures, frames, and chassis. We combine laser cutting (up to 20 mm thickness), CNC press braking (±0.1° bending accuracy), and certified welding to ensure flatness, strength, and aesthetics.

No MOQ & Flexible Batch Sizes
Prototype (1-10 pcs), low-volume, or mass production - we adjust our process to match your budget and timeline.

Value-Added Finishes
Powder coating, anodizing, electroplating, sandblasting, brushing, passivation, and heat treatment - all in-house or through trusted partners to save you logistics.

Rapid Prototyping to Production
Average lead time: 7-14 days for prototypes, 3-4 weeks for mass production. Expedited services available for urgent orders.
