Precision CNC Machining Services — 3/4/5-Axis Milling & Turning
±0.01mm Tolerance | Aluminum, Stainless Steel, Titanium & Engineering Plastics
Our CNC machining services deliver complex metal and plastic components with tolerances down to ±0.01mm. Equipped with 3-axis, 4-axis, and 5-axis CNC machining centers, we handle everything from intricate aerospace brackets to high-volume automotive housings with consistent dimensional accuracy. Maximum part size 1,200 x 800 x 600mm.
We specialize in aluminum 6061-T6/7075-T6, stainless steel 304/316L, titanium Grade 5 (Ti-6Al-4V), brass, copper, and engineering plastics including PEEK and POM — combined with a mandatory DFM review on every new project to reduce your cost and lead time before the first chip is cut.
Typical applications: aerospace brackets, medical device housings, automotive EV components, industrial automation fixtures, and robotic joints.
3-axis, 4-axis & 5-axis CNC centers for complex geometries, undercuts, and compound angles
±0.01mm standard precision | Surface finish Ra 0.4 – Ra 3.2
Prototype lead time 3–7 days | Production volumes from 1 piece to 100,000+
DFM review included — clients average 15–25% cost reduction
Custom Sheet Metal Fabrication Services — Laser Cutting, Bending, Welding & Finishing
TRUMPF Fiber Laser Cutting (up to 25mm) | CNC Press Brake Bending (up to 4,000mm) | AWS-Certified Robotic TIG/MIG Welding
Our custom sheet metal fabrication services combine TRUMPF fiber laser cutting, CNC press brake forming, and robotic MIG/TIG welding to produce precision structural components and assemblies for industrial machinery, EV applications, and automation enclosures. We cut carbon steel up to 25mm, stainless steel up to 20mm, and aluminum up to 16mm, with maximum bending length of 4,000mm and press force up to 300T.
From simple brackets and chassis panels to complex multi-part weld assemblies, our sheet metal team manages the full production workflow — cutting, bending, welding, and surface finishing — delivering batch-consistent quality with full dimensional documentation on every shipment.
In-house surface finishing: powder coating, anodizing (including hard anodizing), zinc plating, nickel plating, passivation, and laser engraving — eliminating the need for secondary suppliers.
TRUMPF fiber laser cutting — carbon steel up to 25mm, stainless steel up to 20mm, aluminum up to 16mm
CNC press brake bending up to 4,000mm length, 300T press force, ±0.2° angle tolerance
AWS D1.1/D1.2 certified robotic & manual TIG/MIG welding — NDT inspection available

Sheet size up to 1,500 x 3,000mm | Nitrogen cutting for oxide-free edges
High-Volume Metal Stamping Services & Progressive Die Tooling
Progressive Die Stamping, Deep Drawing & Blanking — 10,000 to 1,000,000+ Pieces Per Run
For high-volume OEM production requirements, our metal stamping services deliver repeatable precision at scale. We specialize in progressive die stamping, deep drawing, blanking, and multi-slide forming — producing clips, contacts, brackets, and hardware components for the automotive, electronics, and consumer products industries. Typical production volumes range from 10,000 to 1,000,000+ pieces per run.
Our in-house tooling team designs and maintains custom progressive dies, reducing per-unit cost significantly at volumes above 10,000 pieces. All stamped parts undergo dimensional verification and material certification as standard. In-house die design and maintenance reduce per-unit cost on repeat orders.
Materials processed: copper, brass, spring steel, carbon steel, stainless steel, and aluminum — with material thickness typically 0.2mm to 6mm. Tooling lead time: 2–4 weeks for new progressive dies.

Why Global OEMs Choose Our CNC Machining & Sheet Metal Fabrication Services
Engineering-First Manufacturing, Documented Quality & One-Stop Production — From Prototype to Mass Production
We don’t compete on price alone. OEM clients in 20+ countries return for one reason: we reduce engineering risk between design and production — across both CNC machining and sheet metal fabrication.
Before production begins, our mechanical engineers review your CAD files for tolerance stack-ups, unnecessary features, and material substitution opportunities. Written DFM feedback is delivered within 2 working days of file submission. Clients who adopt our recommendations average 15–25% cost reduction and 20–30% shorter lead times. Lower piece-part cost and faster delivery — validated across hundreds of CNC and sheet metal projects.
Our ISO 9001:2015 quality system covers every stage from raw material procurement to final inspection — for both CNC machined components and sheet metal fabricated assemblies. Every production is verified on our Hexagon CMM coordinate measuring machine. We provide First Article Inspection (FAI) reports, Mill Test Reports (MTRs), and RoHS/REACH compliance declarations as standard. Documented quality from the first piece to final shipment.
CNC machining, sheet metal fabrication, metal stamping, surface finishing, and final assembly under one roof eliminates supplier coordination overhead. One purchase order, one point of contact, one quality system. Most clients reduce their supply chain from 3–4 vendors to 1. Fewer suppliers to manage, faster turnaround, and one point of accountability — from design to delivery.
