XILILAI FAQs
CLEAR ANSWERS.
BEFORE THE CUT.
Answer the questions that affect a precision project: manufacturing route, tolerances, records, timing and technical confidentiality.
What should I include with a precision-machining RFQ?
Send the 3D model together with the controlled 2D drawing whenever tolerances, threads, finishes or inspection notes are important. Include the material, quantity, delivery target and any critical-to-function features. If information is missing, engineering will clarify it against the same part record before issuing a formal quotation.
Prepare your project briefHow do you review a tight tolerance before production?
We do not treat a tolerance as an isolated number. Engineering reviews the material, feature geometry, datum structure, tool access, part size and measurement method together. Achievable critical dimensions, the manufacturing route and any required inspection are then recorded against the approved drawing revision before production release.
See our inspection approachCan I request material certificates or inspection reports?
Yes—state the exact document and standard during quotation. Depending on the agreed scope, the project can include material certificates, certificates of conformity, dimensional results, CMM data or first-article inspection records. Engineering confirms the document format, sampling level, lot traceability and any effect on price or lead time before release.
How are lead time and price confirmed?
Price and timing are confirmed after the manufacturing route has been reviewed against the approved drawing revision, quantity, material, finish and inspection scope. The formal quotation records currency, production lead time, tooling or NRE where applicable, validity and stated exclusions. A material design change or quantity change is handled through a new quotation revision.
How are my drawings and technical files protected?
Website uploads and the customer workspace are not yet open. Agree confidentiality and a file-transfer method with our engineering desk before sending technical files.
What happens if engineering needs more information?
If details are missing, our team will ask by email and identify the part or drawing revision concerned. Confirm revised requirements with engineering before quotation.
