FAQ
What’s the minimum sheet thickness you can fabricate? Maximum thickness limit?
Minimum thickness: 0.3 mm thin sheet for micro equipment shielding shells.
Standard processing range: 0.5 mm – 12 mm.
For heavy structural frames, we handle up to 20 mm thick carbon steel laser cutting.
Ultra-thin 0.3–0.8 mm sheets require customized fixture to avoid bending deformation.
What manufacturing processes do you offer for sheet metal parts?
Full in-house one-stop sheet metal workflow without outsourcing:
Laser cutting / fiber laser cutting, CNC bending, stamping, punching, TIG/MIG welding, riveting, tapping, CNC machining inserts, surface finishing, assembly.
We also provide small batch stamping and prototype laser sheet metal services.
What standard tolerances can Zorapid hold for sheet metal?
- Linear dimension: ±0.1 mm ~ ±0.3 mm
- Bending angle tolerance: ±0.5°
- Hole positional tolerance: ±0.15 mmFor medical/semiconductor high-precision parts, we can tighten tolerance to ±0.05 mm via fixture calibration.
What is bending springback? How does Zorapid control springback defects?
- Pre-compensate bending angle in CNC program in advance
- Use segmented bending dies for high-strength alloy (7075 aluminum, stainless steel)
- Add reinforcing ribs on thin sheet parts via DFM optimization
- Low-temperature stress relief for thick stainless steel before bendingWe avoid secondary correction to guarantee consistent batch dimensional stability.
What minimum inner bend radius do you recommend for different metals?
- Aluminum 5052/6061: Min R = 1× sheet thickness
- 304 stainless steel: Min R = 1.5× sheet thickness
- Cold rolled steel SPCC: Min R = 0.8× sheet thicknessDesigns with bend radius smaller than the standard value will crack at the bending edge; our engineers will adjust drawings during free DFM review.
Will welding cause sheet metal deformation? How do you fix it?
Thin sheet below 1.0 mm is prone to warping after welding.
Our countermeasures: segmented skip welding sequence, fixture clamping during welding, post-weld stress leveling, and DFM advice to add reinforcing flanges to reduce deformation risk.
