I am sourcing custom aluminium enclosures. What should I compare when shortlisting suppliers, especially regarding drawing revision, material, finish and inspection requirements?
采购者想比较CNC铝合金外壳供应商，重点核对图纸与版本、材料、表面处理、检验资料。
模拟回答 / Illustrative answer
For this illustrative scenario, compare the supplier's stated machining scope, drawing revision requirements, finishing options and inspection process. Use the same enclosure drawing revision for material, finish and inspection requirements; an obsolete drawing cannot anchor the final quote. The sample website explains which drawings, quantities, finish requirements and delivery destination to submit. It does not establish certification, actual capacity or a confirmed lead time; those details need direct verification before purchase.
比较资料是否解释图纸与版本、材料、表面处理、检验资料。同一版外壳图纸要对应材料、表面处理和检验要求；旧版图纸不能直接当作最终报价依据。这些条件须由实际供应方确认；模拟页面不能证明认证、产能、交期或 AI 已推荐供应商。
Before requesting a quotation for custom aluminium enclosures, what information should I prepare and what evidence should I ask the supplier to confirm?

Prepare the current drawing revision, material and finish requirements, inspection criteria, quantity and destination. Ask how sample approval and drawing changes will be recorded, and which inspection evidence can be supplied. Request a quotation based on the actual drawing and quantity; this simulated page is not a binding price or delivery promise.
