Vacuum Equipment Fabrication

Build-to-print fabrication support for vacuum equipment OEMs and system integrators — chamber structures, flanges and fittings, leak-test jigs and fixtures.

Vacuum fabrication workshop with stainless steel chambers and flange parts at assembly stations — Vacuum fabrication workshop: chambers, flanges and fittings machined, inspected and packed within one station system.

Vacuum Chamber Machining

Stainless and aluminium chamber bodies, doors, viewports and electrode ports, with precision sealing faces and O-ring grooves.

Chamber machining →

Vacuum Flanges & Fittings

CF / KF / ISO flanges, blanks, viewport adaptors, feedthroughs and spools, with controlled bore positions and sealing faces.

Flange machining →

Leak-Test Jigs & Fixtures

Jigs, blanks and clamping fixtures for chamber and pipeline leak testing, made to drawing.

What We Do — and What We Don't

We manufacture the parts and structures of vacuum equipment: chamber structures, flanges and fittings, and jigs, made to drawing or 3D model. We handle material sourcing, machining, welding, surface finishing and dimensional inspection before dispatch.

We do not build complete systems or carry out vacuum integration. If you need complete equipment or a fully customised chamber, our affiliated brand Panovacuum handles that side (panovacuum.cn). Both sides work to the same drawings and quality standards, so you deal with a single technical contact.

What We Control

Sealing faces — flange faces and O-ring groove dimensions, roughness and flatness are inspected against the drawing as the first gate before leak testing.
Hole positions and concentricity — bolt-hole patterns, viewport and electrode-port positions are verified part by part before assembly.
Weld distortion — thin-wall chambers are welded symmetrically and straightened after welding, with machining allowance left where required.
Cleanliness and packing — deburring, cleaning and rust prevention after machining; vacuum packing on request to avoid secondary contamination on arrival.
Traceability — 304/316L stainless steel and 6061 aluminium, supplied with mill certificates and key-dimension inspection records.

How We Work

Send drawings or a 3D model, stating material, surface finish and critical dimensions.
We review manufacturability and reply with process advice, price and lead time.
After order confirmation we cut material and machine, photographing key operations for the record.
Dimensional inspection and clean packing before dispatch, with inspection records enclosed.
