Sheet Metal Fabrication

Sheet Metal — Precision Metal Forming

Sheet metal fabrication transforms flat metal sheets into finished parts through cutting, bending, folding, roll forming, welding, and riveting. Unlike castings, forgings, or machined parts, the material thickness remains constant throughout. Sheet metal parts are widely used in enclosures, brackets, chassis, panels, and structural components across electronics, telecom, automotive, and industrial equipment.

Material Selection
SPCC — Cold-rolled, ≤3.2mm, electroplating/painted, low cost
SHCC — Hot-rolled, T≥3.0mm, flat panels, low cost
SECC/SGCC — Galvanized, N-grade / P-grade
CU — Brass/red/beryllium, conductive, Ni/Cr plating, high cost
Aluminum — 6061·5052·6063·hard Al, chromate, anodizing
Stainless — Mirror/brushed/matte, no surface treatment, high cost

▶ Vacuum Casting

Vacuum Casting

Vacuum casting is a cost-effective alternative to injection molding for small-batch plastic parts. A silicone rubber mold made from a CNC or SLA master pattern faithfully reproduces every structural detail and surface texture. Each silicone mold produces 10–15 copies, ideal for prototyping, sampling, and bridge production.

Materials

Polyurethane resins from Japan's Hei-Cast and France's Axson — simulating ABS, PMMA, PC, PP, PA, silicone, TPU. Options: transparent, colored, soft rubber to rigid plastic, high-temp (120°C), UL94-V0, glass-filled.

ABS (Black/Natural)
Tolerance: ±0.15mm/100mm, up to ±0.05mm
Mold Life: 10–20 copies
Storage: ~30 days
PC / PMMA (Transparent)
Max: 2.0M×1.2M×1.0M
Lead Time: 7–10 days for ~50 pcs
Silicone / TPU (Soft)
Min Wall: 0.5mm (optimal 1.5–2.5mm)
Finishing: Painting, silk screen, plating

🔬 Three Key Steps
Step 1Master Pattern

We machine or 3D print (SLA/SLS) your CAD drawing into the initial master pattern. After post-processing for structure, fit, and surface finish, it is ready for mold making.

Step 2Silicone Mold Making

The master is suspended in a box, silicone is poured over it and vacuum-degassed. Cured at 40°C for 8–16 hours. Once cured, the master is removed, leaving the cavity ready for casting.

Step 3Part Replication

Resin is poured into the mold inside a vacuum chamber, then cured in an oven. Small parts: 1–3 hours; large parts: 3–6 hours. After curing, the part is removed. Repeat the cycle.

▶ 3D Printing

Metal & Plastic 3D Printing

3D printing is a revolutionary technology that produces parts directly from your CAD data — including geometries that cannot be manufactured by any other method. The process produces solid, complex geometries with internal lattice structures, conformal cooling channels, and other features impossible with traditional machining. Parts are built rapidly with minimal material waste, making it ideal for aerospace, medical, automotive, and other next-generation engineering applications.

Key Benefits
Fully Dense Metal: Complex geometries with precise internal features impossible by machining alone.
Minimal Waste: Rapid builds with less raw material while maximizing strength.
Conformal Cooling: Improved thermal performance, ideal for aerospace and automotive.
Multi-Part Build: Multiple identical parts built simultaneously on one platform.
Applications
✈️ Aerospace
Lightweight lattice structures, complex ducts
⚕️ Medical
Custom implants, surgical guides, prosthetics
🚗 Automotive
Conformal cooling channels, lightweight parts
⚙️ Industrial
End-use parts, jigs, fixtures, tooling inserts
