Why ASEAN for sheet metal and stamping
Thailand's automotive supply chain built one of the deepest metalforming bases in Asia: fiber lasers, CNC press brakes, progressive-die stamping lines and robotic welding cells, run to Japanese OEM discipline. Vietnam adds cost-competitive capacity around Hanoi and Ho Chi Minh City. For brackets, enclosures, chassis and assemblies, buyers typically save 20–40% against domestic fabrication with automotive-grade process control.
Product scope
- Laser cutting & bending — mild steel to 25 mm, stainless to 20 mm, aluminium to 12 mm; ±0.1 mm typical laser tolerance.
- Stamping — progressive and transfer dies, 25–800 ton presses, deep drawing.
- Welded assemblies — MIG/TIG/spot/robotic, with jigs and CMM inspection.
- Finishing — powder coating, e-coating, zinc plating, anodizing, passivation, silk-screen.
How to specify for a clean quote
Quote from 3D STEP files plus 2D drawings with tolerances, material grade and thickness (name the standard: ASTM A1011, JIS G3141, EN 10130), finish spec with coating thickness and color standard (RAL), and annual volume. Mark critical dimensions and cosmetic faces. Drawings without a finish callout are the number-one cause of quote-to-production drift in this category.
Tooling: own it, register it
Stamping dies run USD 2,000–20,000 depending on stations; press-brake and laser work needs no tooling. Pay for dies outright, mark them with your asset tags, and record them in a tooling agreement — ownership clarity is what lets you move suppliers if quality drifts. Ask for die-life guarantees (typical: 500k–1M strokes) and per-piece pricing that excludes amortization so you can see true part cost.
QC checkpoints
- First-article inspection with full dimensional report (CMM for formed parts) before production release.
- Material certificates per lot; coating-thickness and cross-hatch adhesion tests on finished parts.
- Salt-spray hours specified and tested (e.g. 500–1,000 h for outdoor powder coat).
- Packaging that isolates cosmetic faces — interleaving, foam, VCI for corrosion-prone steels.
Cost and MOQ benchmarks
Laser/bend parts: no MOQ beyond a small setup charge at the better shops. Stamping: economical from ~10,000 pcs/year. Indicative savings land at 20–40% versus US/EU job shops on parts over ~USD 5 each; below that, freight eats the advantage unless parts consolidate.
FAQ
Can ASEAN shops hold ±0.05 mm?
On laser-cut flat dimensions, yes; across bends, specify tolerance-per-bend and expect ±0.2–0.3 mm unless you pay for machining datums.
Do factories work from my CAD?
Yes — STEP + PDF drawing is standard. Native files are not required and NDA-gated sharing is normal practice.
How is stainless protected in transit?
PE film on cosmetic faces, dry container with desiccant, and VCI packaging — specify it, sea air is unforgiving.
