图纸与询价
如何准备准确的制造询价资料
完整的询价资料可帮助制造团队理解零件、识别风险，并提供更准确的工艺、成本和交付反馈。
核心提示: A clear CAD model is essential, but the drawing, material, quantity, finish and critical requirements often determine whether the quotation reflects the actual project.
3D CAD文件
Provide the native or neutral CAD model when available. Common formats for discussion include STEP, STP, IGES, X_T and SLDPRT.
二维工程图
Use a controlled 2D drawing to communicate dimensions, tolerances, GD&T, threads, notes, standards and revision status.
材料、数量与工艺
State the required material and standard, quantity, anticipated annual volume and manufacturing process if known. If the process is uncertain, describe the part function and priorities.
关键特征与表面处理
Call out critical dimensions, assembly interfaces, threads, inserts, surface finish and cosmetic zones. Explain the application and operating environment where relevant.
检验、包装与交期
Specify requested inspection or documentation before quotation. Include packaging needs, target timing and any customer approval requirement. Availability is confirmed by project.
版本控制
Clearly identify the current revision and superseded files. One controlled source of requirements reduces avoidable questions during review.
