COVO - Custom tooling engineering review checklist
https://www.chinacovo.com/quote#engineering-review

Start with a drawing, a photo or a question. You do not need every answer to contact us. For a detailed tooling review, these six inputs help define what must be checked before a quotation or drawing is approved.

1. Machine & clamping
Machine brand and model; upper and lower clamping interface; usable working length, open height and capacity from the machine documentation.
Your information: 

2. Part geometry
A dimensioned PDF, DXF or STEP file, or a clear section sketch. Mark bend sequence, inside radii, short flanges, return flanges and part-removal constraints.
Your information: 

3. Sheet material
Material grade, thickness range and strength data when available. Identify coatings, grain direction and which surfaces must remain unmarked.
Your information: 

4. Tooling setup
Existing punch and die references or profile drawings; tool height, die opening, required length, segmentation and any adapters or holders.
Your information: 

5. Acceptance criteria
Critical angles, radii and dimensions with tolerances; how the released part will be measured and the first-piece approval requirements.
Your information: 

6. Production scope
Quantity, batch size, repeat-order needs and requested delivery destination. State any open assumptions that should be confirmed before manufacture.
Your information: 

From drawing to an agreed tooling scope
1. Check whether a standard catalog tool can meet the requirement.
2. Review interface, working height, forming sequence, clearance and part removal for a custom solution.
3. Confirm open assumptions, machine/tool load limits and an acceptance plan with the buyer.
4. Agree the quotation and drawing scope before manufacture; verify the setup with a controlled first piece.

This checklist is for inquiry preparation, not a machine-specific tooling approval or a load rating. Final selection requires the actual machine documentation, tool limits and part data.
