Notes from the shop floor
2026-10-27
Chamber Material: 304L or SUS316L?
Short answer: 304L covers most standard chambers; choose 316L when the process involves corrosive atmospheres or the drawing specifies it. Unsure? Put the operating environment in your RFQ and we will advise — not guess.

FAQ
Questions equipment teams ask us
How large a chamber can you build?
Multi-ton class. Dimensions follow your drawing; a 50-ton crane supports full assembly and turnover, so large chambers ship without sectioning.
What materials do you use?
304L / SUS316L stainless steel as standard. Grades and surface finish follow your drawing and specification.
What is your leak-test capability?
Helium mass-spectrometer leak testing to the 1×10⁻⁹ Pa·m³/s order (UL1000-class), verified per chamber before shipment.
What is your lead time?
Depends on drawing complexity. The quotation includes a milestone schedule that we commit to.
What certifications do you hold?
Certification is in progress (SEMI-related standards and AWS welding systems); audits per customer requirements are welcome — details from sales.
How do I start?
Send your drawing (PDF / DWG / STEP). We perform drawing review, DFM suggestions and quotation; 3D and engineering drawings are welcome.
Is there a minimum order?
Single-piece custom work is accepted — no minimum-order gate, quoted per project.
What warranty do you offer?
Contractual warranty terms apply; every unit ships with its inspection records.
How do overseas customers work with you?
Full English process support — contact [email protected] or +1 307 533 3212; export packing and documentation supported.
What are the payment terms?
Per contract (e.g., 30/70 or agreed LC terms), flexible for industrial customers.
