How to request a vacuum chamber quotation: a drawing is sufficient
Drawings are accepted in PDF, DWG or STEP format. Within 48 hours we return a feasibility assessment, DFM recommendations, a price and a delivery date.

Quotation & delivery
Quote spreads usually reflect how much information the drawing carries, not machining rates.
2 articles in this series
Three quotes for the same chamber drawing can differ by a factor of two. The reason is rarely the machining rate and usually the completeness of information: material and plate thickness, tolerances on key dimensions, seal type, weld and leak-test standards, and the deliverables list. With the information complete, quotes become comparable and lead times calculable. This series covers what to submit, what to agree, and what to inspect against.
What this series covers
- A quotation request needs at minimum: material and thickness, key dimensions and tolerances, seal type, surface treatment, quantity and required date.
- Weld acceptance standard and leak-test criterion belong in the drawing or technical agreement; without them each shop applies its own habit and results are not comparable.
- Agree deliverables up front: inspection report, leak-test record, material certificate, weld records. A missing item stalls acceptance.
- All seven inspection gates are signed off and filed, with the report travelling with the unit, so records exist when a customer audits.

Seven checks a vacuum chamber has to pass
A welded chamber is not a deliverable chamber. Seven checks are carried out, each signed off and filed, and the report is dispatched with the unit. Records remain available for customer audit.

What should be supplied with a quotation request?
Assembly and key-part drawings with material, thickness and tolerances; seal construction and O-ring or metal-seal specification; surface treatment and cleanliness requirements; leak-test criterion; quantity and required date. A 3D model helps, but the tolerances and technical requirements on the drawing are what quoting is based on.
Can a leak-test report be supplied with the chamber?
Yes, and it is best specified in the technical agreement: instrument model, background, test pressure, reading, acceptance value, tester and date. A bare "passed" without background and acceptance value is not usable as evidence in a customer audit.
