Sheet metal chassis trays provide an open formed structure for a specified equipment assembly. The selected reference has a tray floor, bent sidewalls, tabs and cutouts; it is not a complete closed enclosure. Review the overall envelope and every mounting interface with the components that the tray will support. Confirm the material, sheet thickness, bend requirements and finish against the final drawing. Hole positions, access space and formed features should be checked together so that the supplied tray can be assessed as one assembly component.
| Product: Sheet Metal Chassis Trays | |
| Specification: | Use the approved part drawing and purchase requirements |
| Material: | Specify the metal, grade and sheet thickness |
| Dimensions: | Tray envelope, floor dimensions, wall heights, tabs and opening positions |
| Design: | Open chassis tray with bent sidewalls, tabs and cutouts |
| Manufacturing: | Agree cutting, forming, joining and finishing requirements for the selected part |
| Interfaces: | Mounting holes, cutouts and assembly contact surfaces |
| Forming requirements: | Identify bend positions, radii and the dimensions that control assembly fit |
| Finish: | Agree the required finish, appearance sample and masked areas where relevant |
| Inspection: | Confirm dimensional checks, supplied components and required documents |
| Order reference: | Keep the drawing revision, quantity and agreed specification together |





Review sheet metal chassis trays as part of the complete equipment assembly. Identify tray envelope, floor dimensions, wall heights, tabs and opening positions and confirm mounting holes, cutouts and assembly contact surfaces against the agreed drawing revision.
For a new part, provide the intended assembly interfaces, material, sheet thickness, quantity and finish reference. For a replacement, include photographs and identify which dimensions are measured and which still need confirmation. A similar-looking sample does not establish interchangeable fit.
Agree the manufacturing route and inspection scope for the selected drawing. Cutting, forming, joining and finishing requirements should identify the features they apply to. Do not infer tolerances, structural capacity or certification from the reference image or a generic product name.
Keep the enquiry, quotation and final order tied to one product reference. List the components expected in the supply and identify any parts or fixings that will be provided separately. Review proposed drawing changes before production so that they are reflected in the order record.
Compare the other Sheet Metal Fabrication products, then send Hengke Casting the selected configuration, controlled drawing and required quantity.
