In advanced manufacturing, sheet metal carries the rack, shell, shield, cable tray and load structure. Semiconductor equipment is sensitive to particles, ESD and outgassing; gas systems to sealing and corrosion; medical to appearance, cleaning and traceability. Choose a shop by process (welding, deburr, cleaning), finish and QC — not just price.
The enclosure is not just "wrapping the device" — it becomes part of the clean environment, EMC and safety compliance. Xingyuan's laser cut, CNC punch, CNC bend, laser weld, aluminum weld and in-house coating line builds precision structures and gas cabinets, with build-to-drawing and DFM cost-down.
Shells and structures need controlled particle shedding, burr and static. Our approach: laser cut for clean edges and low burr, CNC bend for springback and consistency, post-weld stress relief and polish, ESD coating or conductive oxidation for key parts; low-outgassing stainless and aluminum with clean packing and process isolation.
GCs carry toxic, flammable or corrosive process gas. Key is sealing, corrosion resistance and relief: 304 stainless, gas-tight welds with inspection, sealed door and penetrations, with relief and exhaust预留. We select material by gas type and pressure class, with mounting holes and earthing.
| Item | What drives price |
|---|---|
| Material | Grade (SPCC/aluminum/stainless), thickness, utilization |
| Process | Cut (laser/punch), bend count, weld difficulty, deburr |
| Finish | Coating/electrophoresis/passivation, pre-treatment, film |
| QC | CMM, gas-tight test, cleanliness, traceability |
| Qty | Batch amortizes tooling; one-off higher unit cost |
Most common; RAL colors; weather and appearance; for shells and frames.
Even film, good inner coverage; for complex, anti-corrosion parts.
Stainless and aluminum corrosion/conductive treatment for semiconductor and conductive use.
Tolerances are controlled by bend springback, hole accumulation and weld distortion; key dims are accepted per drawing with CMM and gauges. We confirm tolerance and acceptance at drawing stage, relieve stress after welding, and provide reports and traceability for critical parts.
Engineers review manufacturability: bend sequence, weld access, tolerance optimization.
Simplify structure, unify material/process without hurting function to lower unit cost.
Sample confirm then mass; small batches supported; 7-15 days typical.
Control particle shedding, burr and ESD: laser cut for clean edges, post-weld relief and polish, ESD coating or conductive oxide for key parts, low-outgassing stainless/aluminum with clean packing.
Usually 304 stainless, gas-tight welds with inspection, sealed door and penetrations, selected by gas and pressure class.
Material grade and thickness, process complexity (cut/bend/weld), finish, QC and quantity. Send drawing or list for a quick quote.
Shells: powder coating; complex anti-corrosion: electrophoresis; stainless/aluminum conductive: passivation or oxide.
Per drawing with CMM and gauges; stress relief after welding; reports and traceability for critical parts.
Yes. At review we propose bend sequence, weld access and tolerance optimization to lower unit cost without hurting function.
Yes. Based in Lili Town, Wujiang, Suzhou; customers from Suzhou, Wuxi, Shanghai, Kunshan can visit, inspect and sample.
