Sheet Metal Design Guidelines

Designing for manufacturability reduces costs, improves quality, and accelerates lead times. Our engineering team reviews every project for DFM optimization—but these guidelines help you create production-ready designs from the start.

📐

Bend Radii

Minimum inside bend radius should equal material thickness for steel, 1.5× for aluminum to prevent cracking.

Min Radius = 1.0T (steel)
📏

Hole-to-Edge Distance

Maintain minimum distance from hole edge to bend line to prevent distortion during forming.

Min = 2.5T + Bend Radius
🔩

Hole-to-Hole Spacing

Minimum spacing between holes prevents material deformation and ensures punch tool clearance.

Min = 2× Material Thickness
↔️

Flange Height

Minimum flange height ensures proper forming without material tearing or springback issues.

Min = 4T + Bend Radius
🎯

Feature Proximity

Keep features (holes, slots, tabs) away from bends to maintain dimensional accuracy.

Distance = 3T minimum
📊

General Tolerances

Standard tolerances for laser cutting, bending, and assembled dimensions.

±0.1mm to ±0.5mm typical

Standard Manufacturing Tolerances

The table below reflects our standard and precision capabilities. Standard tolerances apply unless tighter values are specified on your drawing. Tighter tolerances may increase cost and lead time — specify them only on functionally critical dimensions.

Feature / Process Standard Tolerance Precision (on request) Notes
Laser cutting — linear ± 0.10 mm ± 0.05 mm For material thickness ≤ 3 mm
Laser cutting — hole diameter ± 0.10 mm ± 0.05 mm Holes < 1 mm not recommended for laser
CNC punching — hole position ± 0.10 mm ± 0.05 mm Relative to datum
Bending — angle ± 0.5° ± 0.25° Springback varies with material and thickness
Bending — flange length ± 0.20 mm ± 0.10 mm Measured from bend line to edge
Overall dimensions (< 300 mm) ± 0.20 mm ± 0.10 mm Cumulative tolerance applies for multi-bend parts
Overall dimensions (300–1000 mm) ± 0.30 mm ± 0.15 mm Use datum references for critical fits
Overall dimensions (> 1000 mm) ± 0.50 mm ± 0.25 mm Large parts may require fixture verification
Flatness 0.5 mm / 300 mm 0.2 mm / 300 mm After leveling; thin sheets may require fixturing
Hardware insertion position ± 0.15 mm ± 0.08 mm PEM / clinch nuts, studs, standoffs
Welding distortion ± 0.3–0.5 mm ± 0.15 mm Precision achievable with fixtures and laser welding
Powder coat thickness 60–80 μm 40–120 μm range Adjustable per specification

Frequently Asked Questions

Common questions from engineers and procurement teams about our sheet metal fabrication services.

Don't See Your Question?

Our engineering team is ready to help.

What file formats do you accept for quoting?

+
We accept STEP, STP, IGES, DXF, DWG, and PDF drawings. SolidWorks, AutoCAD, Pro-E, and UG native files are also supported. For fastest quotes, 3D STEP files with 2D drawings showing critical dimensions are ideal. If you only have a sample or concept sketch, our engineering team can help develop production-ready drawings.

What is your minimum order quantity?

+
No strict MOQ. We welcome prototypes starting from 1 piece. For simple laser-cut and bent parts, orders of any quantity are accepted. For parts requiring progressive dies or custom tooling, the MOQ is typically 500–1,000 pieces to justify tooling investment. Optimal pricing generally starts at 500+ pieces per run.

What are your standard lead times?

+
Prototypes: 7–14 days. Standard production (laser cutting + bending): 2–3 weeks. Complex assemblies with multi-process operations: 3–4 weeks. Add 3–5 days if surface finishing (powder coating, plating) is required. Rush services are available for urgent projects — contact us for expedited timelines.

Do you provide surface finishing services?

+
Yes — surface finishing is one of our core in-house capabilities. We operate a 525-meter automated powder coating line with Swiss Gema spray guns, handling up to 15,000 m² per day. Available finishes include powder coating (RAL/Pantone colors, gloss to matte), zinc/nickel/chrome plating, anodizing, e-coat, brushing, and polishing. Parts ship finished and ready to install — no secondary supplier coordination needed.

How do you ensure quality?

+
We are ISO 9001:2015 and IATF 16949:2016 (automotive) certified with a multi-stage QC process: incoming material inspection with mill certificates, first article inspection (FAI) for all new parts, in-process checks at every manufacturing stage, and 100% final inspection before packaging. Our QC lab includes 2× CMM machines (Serein Croma), optical projectors, salt spray testers, material testing machines, and coating thickness gauges. PPAP documentation and full dimensional reports are available on request.

What is the maximum part size?

+
Laser cutting: 3,000 × 1,500 mm. CNC bending: up to 3,000 mm length (AMADA RG-100). Largest stamping press table: 5,000 × 1,800 mm. Powder coating: maximum part size 2,200 × 1,500 × 600 mm. For oversized parts, contact our engineering team to discuss feasibility.

What materials do you work with?

+
We regularly process cold rolled steel (SPCC/DC01), galvanized steel (SGCC/DX51D), stainless steel (304, 316), aluminum (5052, 6061), copper, and brass. Material thickness range is 0.5 mm to 6.0 mm. We can source specialty alloys on request. Our engineering team can recommend the best material for your specific application, balancing cost, performance, and manufacturability.

Do you offer design assistance or DFM review?

+
Yes — every quote includes a free DFM (Design for Manufacturability) review from our engineering team. We use AutoForm simulation software to analyze forming and stretching before tooling. If we identify opportunities to reduce cost, improve quality, or simplify manufacturing, we'll share specific recommendations within 24 hours. This typically saves clients 15–30% on production costs.

Can you handle both prototyping and volume production?

+
Absolutely. We support the full product lifecycle — from single prototypes for design validation through to high-volume production runs. Our facility houses 76 stamping presses (110T–1,200T) with a daily capacity of 480,000 press strokes, alongside laser cutting and CNC bending for lower-volume work. Many clients start with prototypes and transition seamlessly to production with us once designs are finalized.

How do you handle shipping and export?

+
We ship worldwide via express courier (DHL/FedEx/UPS, 3–5 days), air freight (5–10 days), and sea freight (LCL or FCL, 20–35 days). Trade terms include FOB, CIF, and DDP. All shipments include commercial invoice, packing list, certificate of origin, and material certifications on request. Custom packaging is designed for each product to prevent damage during transit. We photograph all shipments before dispatch for your records.
