Our 12kW fiber laser cuts mild steel to 25 mm, stainless to 20 mm, aluminum to 20 mm, brass to 12 mm, copper to 8 mm. For thicker materials we use plasma cutting (up to 50 mm steel) or waterjet (any thickness, any material) — both available in-house.

Standard bend tolerance: ±0.1° on bend angle, ±0.1 mm on flange length. Tighter is possible (±0.05° on critical-fit parts) but requires CMM verification + sometimes a custom bend tool. We always achieve tighter tolerances on shorter flanges (<100 mm); long flanges (>1 m) hold ±0.2 mm typically due to material springback variation.

Cold-rolled steel, hot-rolled steel, galvanized steel, stainless 304/316, aluminum 5052/6061, brass C260/C360, copper C110, and pre-plated steels (aluminized, electrogalvanized, tin-plate). Material thickness range: 0.5 mm to 25 mm for laser cutting; 0.8 mm to 8 mm for press brake bending.

Yes. AWS-qualified welders for both. Aluminum TIG using AlSi or 5356 filler depending on the alloy combination. Stainless TIG with matching filler (308L for 304, 316L for 316). We can also do MIG aluminum on production-volume frames. Visible-surface welds are dressed smooth or polished to spec. Spot welding for thin-gauge enclosures.

Yes. Powder coating (any RAL or Pantone color, hot-cured to 200°C), wet paint, electroplating (zinc, nickel, chrome, gold), anodizing (Type II decorative, Type III hard-coat) for aluminum, passivation for stainless, silkscreen and pad printing for branding and labels. We pre-compensate dimensions for plating thickness so finished parts hit drawing.

Yes. We stock PEM nuts, studs, standoffs in the most common sizes (M3-M8, #4-40 to 1/4-20 imperial). Self-clinching hardware installed on cold-press for repeatability. Heat-set inserts for plastic parts. Loose hardware can also be included in the shipment if you prefer to install yourself.

Single-piece prototypes typically $30-$300 depending on material, complexity, and finish. Low volume (10-100 pcs) drops to $15-$150/piece. Production volumes (500-5,000 pcs) range $3-$60/piece. Material thickness, bend count, weld inches, and finish are the main cost drivers. Send your DXF for an exact quote in 4 hours.

Best: DXF (flat pattern) — fastest to quote and cut. Also accepted: STEP / IGES (3D), SolidWorks, AutoCAD DWG, PDF (good drawing only, for simple parts). We can convert from 3D to flat pattern for you at no charge if needed, but providing the DXF saves you time on quote turnaround.

Yes. Complex welded enclosures, frames, machine bases, weldments. Pre-fit / tack-weld review available — we'll send photos before final welds so you can confirm fit. Robotic MIG for high-volume frames; manual TIG/MIG for prototypes and short runs. Stress-relief annealing on heavy weldments by request.

Standard lead times: 5-7 working days for prototype/low volume, 10-15 days for production runs (500-5,000 pcs), 15-25 days for large enclosures with multi-finish and assembly. Rush (24-48 hour) available for simple laser-cut parts when capacity allows. Quote response within 4 hours of file upload.
