Sheet Metal Fabrication, Laser Cutting, CNC Punching, CNC Bending, Welding

Service Categories

We offer three main categories of sheet metal fabricated parts, ranging from protective enclosures to load‑bearing structures and welded assemblies.

Metal Enclosures & Housings

Typical products: Server racks, electrical cabinets, medical device housings, charger enclosures, instrument cases, EMI/RFI shielding covers

Key features: Precise dimensions, clean aesthetics, durable surface finishes (powder coating, silk screening)

Function: Protect internal components from dust, moisture, impact, and electromagnetic interference

Structural Components

Typical products: Equipment frames, mounting brackets, base plates, robot stands, chassis supports, battery trays

Key features: High strength, rigidity, lightweight design (using ribs or folded geometry)

Function: Provide load‑bearing support and maintain alignment of assembled systems

Welded Assemblies

Typical products: Welded frames, tank bodies, hoppers, machine bases, console desks, multi‑part enclosures

Key features: Strong joints, controlled distortion, leak‑tight construction (when required)

Function: Integrate multiple sheet metal parts into a single robust structure or complex enclosure

Industries We Serve

Our sheet metal fabrication services are used across the same eight industries as our CNC machining, but here we emphasise the **structural support and protective functions** of sheet metal parts.

Automation / Robotics

Sheet metal parts: Robot base frames, controller enclosures, protective covers, mounting brackets for sensors

Role: Provide rigid support for moving parts; shield electronics from debris and coolant

New Energy

Sheet metal parts: Energy storage cabinet enclosures, battery tray assemblies, charger outer shells, inverter boxes

Role: Protect sensitive electrical components from weather, dust, and mechanical impact; ensure thermal management via ventilation design

Military / Security

Sheet metal parts: Rugged equipment cases, antenna mounts, shelter panels, weapon station enclosures

Role: Withstand extreme environments (shock, vibration, temperature); provide EMI shielding and ballistic protection when specified

Optical Instruments / Precision Measurement

Sheet metal parts: Instrument chassis, optical bench covers, mounting plates for lenses/mirrors

Role: Minimise thermal distortion; provide stable, vibration‑damped platforms; protect sensitive optics from contamination

Semiconductor / Electronics

Sheet metal parts: Equipment covers, EMI shielding cans, rack‑mount enclosures, wafer carrier boxes

Role: Electromagnetic interference suppression; cleanroom‑compatible surfaces; ESD protection

Automotive Components

Sheet metal parts: Battery pack enclosures (EV), mounting brackets, heat shields, dashboard skeletons

Role: Lightweight structural support; protect batteries from crash impact; manage heat from exhaust or motors

Medical Devices

Sheet metal parts: Cart housings, imaging equipment covers, sterilizer cabinets, patient lift frames

Role: Smooth, easy‑to‑clean surfaces (hygienic); structural integrity for mobile equipment; corrosion resistance to cleaning agents

Aerospace

Sheet metal parts: Avionics enclosures, interior trim brackets, galley structures, access panels

Role: High strength‑to‑weight ratio; flame‑retardant finishes; reliable performance under vibration and pressure changes
