Precision Sheet Metal Fabrication · Semiconductor / Gas Cabinet / Medical

Xingyuan Electric (Suzhou) is a precision sheet metal manufacturer for semiconductor, specialty gas and medical industries, building equipment shells, frames, structures and specialty gas cabinets (GC). With 52 staff, 5,000+ m2 and 20+ laser/CNC machines, we cover cleanliness and ESD, surface treatment, tolerances and inspection, support build-to-drawing and DFM cost-down, with factory visits welcome.

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.

Where precision sheet metal sits in advanced manufacturing

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.

Semiconductor equipment sheet metal: cleanliness & ESD

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.

Semiconductor project: Send spec, clean class, material and ESD requirement — we assess process and QC.

Specialty gas cabinet (GC): safety & compliance

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.

GC customization: Tell us gas type, pressure, material and interface standard — we assess.

How sheet metal quoting works

ItemWhat drives price
MaterialGrade (SPCC/aluminum/stainless), thickness, utilization
ProcessCut (laser/punch), bend count, weld difficulty, deburr
FinishCoating/electrophoresis/passivation, pre-treatment, film
QCCMM, gas-tight test, cleanliness, traceability
QtyBatch amortizes tooling; one-off higher unit cost

Surface treatment selection

Powder coating

Most common; RAL colors; weather and appearance; for shells and frames.

Electrophoresis

Even film, good inner coverage; for complex, anti-corrosion parts.

Passivation/oxide

Stainless and aluminum corrosion/conductive treatment for semiconductor and conductive use.

Tolerances & inspection

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.

Process & DFM cost-down

Review

Engineers review manufacturability: bend sequence, weld access, tolerance optimization.

DFM

Simplify structure, unify material/process without hurting function to lower unit cost.

Sample & mass

Sample confirm then mass; small batches supported; 7-15 days typical.

FAQ

What cleanliness do semiconductor parts need?

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.

What material for a gas cabinet?

Usually 304 stainless, gas-tight welds with inspection, sealed door and penetrations, selected by gas and pressure class.

What drives sheet metal price?

Material grade and thickness, process complexity (cut/bend/weld), finish, QC and quantity. Send drawing or list for a quick quote.

How to choose surface treatment?

Shells: powder coating; complex anti-corrosion: electrophoresis; stainless/aluminum conductive: passivation or oxide.

How are tolerances accepted?

Per drawing with CMM and gauges; stress relief after welding; reports and traceability for critical parts.

Do you offer DFM cost-down?

Yes. At review we propose bend sequence, weld access and tolerance optimization to lower unit cost without hurting function.

Can we visit the factory?

Yes. Based in Lili Town, Wujiang, Suzhou; customers from Suzhou, Wuxi, Shanghai, Kunshan can visit, inspect and sample.
