Material & 厚度
指定材料标准, 等级, 状态和标称厚度. 在询价或图纸上标明允许的材料替代, 作为等级的变化, condition or thickness may affect forming and finishing decisions.
定义零件的组装状态
展示零件如何安装和工作. 保持成型模型, 图纸和任何提供的平面图处于同一修订版本.
Bends & nearby features
Identify bend directions, angles and functionally important radii. Highlight holes, slots and cutouts near bends so their final condition and forming access can be reviewed together.
Mounting & mating surfaces
Mark the datums, hole patterns and clearances that control installation. Include the mating component or an assembly view where an isolated part drawing leaves the fit unclear.
Choose a route that fits the design and demand
The appropriate route depends on geometry, quantities, secondary operations and acceptance requirements. Cutting, bending and stamping may be considered during project review where applicable.
Cutting & bending
A route to assess for flat profiles and formed components, particularly when design changes remain likely. Discuss cutting method, bend access and any secondary operations together.
Dedicated stamping tooling
A route to evaluate when a stable design and expected repeat demand can support tooling investment. Clarify tooling cost, ownership, maintenance and the effect of future design changes.
Compare the total supply scope
Include joining, hardware, 加工完成, inspection and packaging in the comparison. A lower cost at one operation may not produce the best overall route for the finished assembly.
Define joining and finishing with the part requirements
Define these requirements before the route is agreed. Their effect on fit, appearance and inspection should be included in the quotation scope.
Joints & installed hardware
Identify weld locations, inserts, rivets or fasteners and any access restrictions. Specify alignment and any required strength or sealing tests. Confirm the assembly operations and verification included in supply.
Visible surfaces & 受保护区域
Mark cosmetic faces, acceptable edge condition, finish requirements and areas to mask or protect. State whether critical dimensions apply before or after coating, and identify contact surfaces that must remain functional.
Agree how the formed part will be accepted
Critical features need a shared reference condition. Define whether dimensions are checked in the free state, after joining or in an agreed fixture.

Dimensional requirements
Identify the dimensions and tolerances that control assembly. Review bend angles, hole locations and interface relationships as part of the complete formed geometry.
外观 & function
Clarify acceptable burrs, edge treatment, visible marks and finish variation. 如果样品或视觉标准决定验收, 确认其修订版本和批准状态.

Sheet metal project questions
Should I send a flat pattern or a formed model?
Send the formed model and dimensioned drawing, together with a flat pattern if available. Identify the governing revision and agree responsibility for the developed blank before manufacture.
Can you quote from a drawing without a fixed manufacturing route?
Share the finished-part requirements, quantity and expected repeat demand. The discussion can then identify which routes merit assessment and which details need to be resolved before a quotation is confirmed.
What tolerances should I put on the drawing?
Start with the dimensions that control fit and function. Make the measurement condition explicit and identify any governing drawing standard. Feasibility is reviewed for the geometry, material and proposed process.
When should stamping be considered?
Assess stamping when the design, expected demand and tooling investment justify a comparison. Include future changes, secondary operations and acceptance requirements; there is no single quantity threshold for every part.
What if some features need machining?
Identify the features and final tolerances in the drawing. Review the sequence alongside forming and joining, and see CNC 加工服务 for the related machining scope.
Ready to review your sheet metal project?
Send the current drawing revision, 材料, quantities and critical interfaces. The project scope, manufacturing route and acceptance requirements are reviewed before quotation.
