从单个机加工件到多供应商的成套项目——每个合作都从一张图纸开始，以一份你可以核查的文件结束。
A standing presence on the factory floor for buyers running several programmes at once.
Milestone checks, dimensional reports and consolidation before anything is released.
Samples and first article inspection approved before the batch runs, with tooling ownership written into the order.
Three to five comparable quotes, itemised, so you can see what you are actually paying for.
Shortlist, licence and capacity checks, and an on-site visit before you commit.
一个 STEP 文件、一份 PDF 或一张零件照片就够了。48 小时内你会拿到供应商短名单、分项比价和一份切实可行的时间表。
