One-stop precision sheet metal manufacturing
Medical and semiconductor equipment runs on surfaces and tolerances that have to be documented rather than asserted. Cleanable stainless housings, instrument enclosures and precision machined or ground components, delivered with the inspection record the sector expects.
Data centers, industrial automation, ventilation and filtration, medical equipment, semiconductor tooling, marine equipment and new-energy charging infrastructure.
Four things that decide whether a metal enclosure project lands on time and on budget.
Tolerances we can hold
±0.1 mm on laser-cut features and ±0.3 mm on formed parts, verified before dispatch.
Quality you can audit
ISO 9001 processes, first-article inspection and a measurement report with every series batch.
One supplier, five processes
Cutting, bending, welding, coating and mechanical assembly under one roof — no hand-offs between vendors.
Built for export
Export-grade packing, customs documentation and container loading planned for Europe and North America.

Medical instruments and semiconductor tools are the two environments where surface finish, cleanliness and dimensional stability stop being cosmetic. One is inspected closely by clinicians and patients, the other by process engineers chasing particles. Both punish a housing that was finished by eye. We build instrument enclosures, patient-facing terminals and tool frames where finish and flatness are specified, measured and recorded.
Four requirements that come up on almost every medical or semiconductor programme.
Flatness and stability
An optical bench that moves with temperature will not hold focus. Bases and mounting faces are machined or ground after forming, and stability is designed in with section and material rather than corrected with shims in the field.
Cosmetic surface standard
Brushed, polished and coated surfaces are matched across every panel in the build, and the grain direction is set so it reads the same on all faces. Cosmetic faces are masked through every downstream operation.
Cleanability and particle control
Surfaces that face the process are free of open seams, crevices and unsealed fixings where particles collect. Assemblies are cleaned before the enclosure is closed, not after.
Traceability
Every part is traceable through MES to its electronic quality record, and inspection reports, hardware records and test results ship with the batch — which is what an audit actually asks for.
Optical sorter cabinets, infeed frames and buffer hoppers for Tomra (Norway). Anti-stray light precision is achieved through bending tolerance, robot seam welding and matte black interior coating. Highlights: precision light sealing, 6.5 m gantry machining in one setup, matte black interior.
Deep-drawn fan scrolls, guide rings and impeller shrouds for Ziehl-Abegg (Germany). One-piece forming means fewer seams and smoother inner walls, so pressure loss and noise stay low. Highlights: one-piece deep drawing, robot circumferential sealing weld, accurate balance datum.
Vertical collector housings with conical dust hoppers and support frames for Camfil (Sweden). Fully welded gas-tight construction with machined sealing flanges. Highlights: gas-tight welding, anti-bridging hopper forming, machined flange faces, outdoor-grade coating.
Laser machine control cabinet and sealed top housing (sheet metal structure only) for Trumpf (Germany). Sealing is continuous across the top joint so the IP66 rating carries across the whole cabinet. Highlights: IP66 sealing, sealed top transition, oil-resistant industrial coating.
Split upper and lower equipment frames with a machined mounting plate between them for AP TECH (Korea). The 6.5 m gantry mills the mounting face in one setup and assembly gaps are held uniformly. Highlights: gantry-machined mounting face, granite plate fitting, assembly gap control, rigid vibration-damped frame.
Sectioned conveyor frames, support structures, side guarding and drive housings (sheet metal structure only) for Vanderlande (Netherlands). 8 m rail-mounted robot welding keeps long sections straight and interfaces interchangeable. Highlights: long-section robot welding, interchangeable section interfaces, outdoor salt-spray coating.
Quality is measured, not claimed. A precision inspection system compares 40 million measurement points against your CAD in 0.1 seconds per part, and every batch is documented under our ISO 9001 system. Reference customers include TOMRA, TRUMPF, RITTAL, ZIEHL-ABEGG, CAMFIL, VANDERLANDE, MAHLE and WEISS TECHNIK.
There is no fixed MOQ. Prototypes and small batches from one piece are accepted, and unit prices fall as volume grows. One-off tooling cost is quoted separately.
Yes. We regularly work under NDA and produce strictly to customer drawings. Files stay on an internal server and are never shared with third parties.
A first-article sample is typically ready in 7–10 working days, and series production runs in 3–5 weeks depending on quantity and surface finish.
