Full In-House Manufacturing Capabilities
Six integrated processes mean tighter control, shorter lead times and one point of contact — no sub-contracting risk.
CNC Machining
25+ CNC turning & milling centers, 4-axis drill-tap cells and gantry machining up to 3000×1600 mm. Tolerances to ±0.005 mm.
Aluminum Die Casting
In-house die-casting cells for aluminum and zinc housings and structural parts, followed by precision CNC finishing.
Sheet Metal & Laser
Fiber laser cutting, CNC punching, press-brake bending and laser welding for frames, panels and enclosures.
Surface Treatment
Multi-color anodizing, electroplating, passivation, sandblasting and powder coating — finished and inspected on site.
Mold & Tooling
Our own mold-design and tool-room build die-casting molds, jigs and fixtures — protecting your IP and your timeline.
Quality Inspection
CMM (0.001 mm), Mitutoyo gauging, granite tables and full dimensional reports with every shipment.
Built for Demanding Export Customers
One-Stop Source
Casting, machining, fabrication and finishing in one plant — fewer suppliers, fewer risks, one accountable partner.
Export Experience
Already shipping to Germany, the USA and Europe. We read English/metric & imperial drawings and quote fast.
Precision Verified
CMM-controlled inspection to 0.001 mm with documented reports — quality you can prove to your own customers.
Engineering Support
10 engineers provide DFM feedback, material advice and tooling design to reduce your cost and time-to-market.
Precision Components We Manufacture
Custom-made to your drawings. A selection of machined, die-cast and surface-finished parts from our production floor.
From Drawing to Delivery
Inquiry & DFM
Send drawings or samples. We review feasibility and suggest cost-down options.
Quote & Tooling
Transparent quotation, then mold / fixture design and build in-house.
Sampling
First articles produced and CMM-inspected for your approval before mass run.
Production
Cast, machine, fabricate and surface-finish under one quality system.
QC & Shipping
Final inspection, reports, export packing and on-time global delivery.
Measured, Documented, Guaranteed
Quality is verified, not assumed. A dedicated inspection room with coordinate measuring machines and calibrated gauging controls every critical dimension — and every order ships with documentation your engineers can trust.
