Manufacturing Capabilities

Sheet Metal Processes from Drawing Review to Assembly

We run fiber laser cutting, CNC punching, precision bending, welding, hardware insertion, in-house surface prep, partner finishing, and assembly for industrial OEM parts. Our team gives DFM feedback before metal is cut so you can plan tolerances, finish sequence, and lead time with fewer surprises.

Equipment snapshot

5 fiber lasers (to 2000 × 4000 mm), 7 CNC press brakes (to 230T / 3000 mm), CNC punching, and multi-process welding in our 3,500 m² Dongguan facility.

Typical tolerances

Laser ±0.10 mm; bending ±0.20–0.30 mm; holes ±0.10–0.20 mm—always confirmed against your drawing, material, and geometry.

DFM / RFQ cues

Share STEP/DXF/PDF, bend notes, PEM callouts, weld symbols, finish specs, and critical faces so we can flag risk before nesting.

How we run a multi-process job

Most OEM parts we build are not laser-only blanks. A typical enclosure, chassis, or bracket stack moves through flat-pattern review, cutting or punching, CNC bending, hardware insertion, welding or grinding where required, then in-house prep and partner finishing. We keep that chain under one project owner so you are not coordinating three shops for one assembly.

Cutting and punching

Fiber laser profiles sheet to 2000 × 4000 mm. Typical capacity: stainless to 20 mm, carbon steel to 25 mm, aluminum to 16 mm. CNC punching is used when dense hole patterns, louvers, or formed features are more efficient than laser-only nesting. We review kerf, micro-joints, grain direction, and nest efficiency against cosmetic faces you mark on the drawing.

If your design mixes thick structural panels with thin covers, we split process notes by thickness so bend and weld assumptions stay realistic. Edge quality expectations (as-cut, deburred, or brushed) should be stated in the RFQ—especially for visible faces and gasket lands.

Bending, hardware, and weld

CNC press brakes to 230T / 3000 mm handle enclosure boxes, U-channels, brackets, and frames. We review bend sequence, reliefs, minimum flange length, and punch/die selection before first article. PEM nuts/standoffs, riveting, and M2–M12 tapping are inserted so panels arrive ready for line assembly.

TIG, MIG/MAG, laser, and spot welding cover structural and cosmetic weldments. Call out grind/brush zones and distortion-sensitive faces early; we will propose stitch vs continuous welds or fixture notes when the drawing leaves that open.

Drawing-dependent process ranges

The ranges below are planning values our team uses when reviewing RFQs. Final capability always depends on material grade, thickness, feature density, and your GD&T. Call out datum schemes and cosmetic faces so we can confirm process capability before we commit lead time.

Typical sheet range: 0.5–12 mm fabricated sheet (laser extends thicker by alloy)
Laser tolerance (typical): ±0.10 mm
Bending tolerance (typical): ±0.20–0.30 mm
Hole tolerance (typical): ±0.10–0.20 mm
Press brake capacity: Up to 230T / 3000 mm

DFM tips that reduce rework

Bend radius: Keep inside radius ≥ material thickness unless we confirm tooling for a tighter radius on your alloy.
Hole-to-bend clearance: Keep holes and slots far enough from bend lines to avoid ovalizing; we flag conflicts during flat-pattern review.
Hardware: Specify PEM type, grip range, and keep-out zones. Blind inserts near bends need sequence notes.
Weld access: Leave torch and clamp access on box corners; mark cosmetic vs structural seams.
Finish sequence: Note whether powder, anodize, plate, or passivate is required before or after hardware—partners handle coatings; we own prep and coordination.
Critical faces: Mark gasket lands, hinge lines, connector cutouts, and paint-free zones on the PDF.

Finishing ownership: Deburr, grind, and brush are in-house. Powder coating, anodizing, plating, passivation, sandblasting, electropolishing, screen printing, and laser marking run through qualified finishing partners—not claimed as wholly in-house.

RFQ checklist for a usable quote

Email-only RFQs work best when the package answers process questions up front. Incomplete drawings force assumptions on bend reliefs, hardware, and finish that later become change orders.

PDF plus DXF or STEP (SolidWorks welcome) with revision
Material grade and thickness; quantity by phase (prototype / NPI / production)
Bend notes, weld symbols, PEM/hardware callouts
Finish, marking, cosmetic zones, and paint-free areas
Critical dimensions, GD&T, and inspection expectations (FAI, CoC, dimensional report)
Target delivery and any export packaging notes

Quality and lead-time planning

Our ISO 9001:2015 quality flow covers IQC, FAI, IPQC, FQC, and OQC. Inspection resources include CMM, 2.5D vision, height gauges, and standard metrology when your drawing or PO requires documented checks. Available paperwork includes first-article inspection, dimensional reports, material certificates, RoHS/REACH statements, and coating reports from finishing partners when applicable.

Typical lead times (confirm against scope and finish queue): prototypes 3–12 working days; small batches 10–15 days; regular production 15–25 days. MOQ of one piece is available for fit and process checks. Child process pages below detail laser cutting, punching, bending, welding, hardware, finishing, and assembly—use them for process-specific notes, then send the drawing package for a firm review.
