SELECTION & ORDER BASIS
Specify the application before the model.
A custom-part RFQ begins with controlled technical input: drawing revision or sample, material, tolerances, critical features, process preference, finish, inspection plan, prototype quantity and annual demand.
Send drawings or samples with material, tolerance, surface treatment, testing, annual quantity and target delivery requirements.
ZECH supports industrial distributors and project buyers with model matching, catalog specifications, packaging confirmation and order-specific documentation. Final technical details are confirmed with the quotation.
DIRECT BUYER ANSWER
How should buyers specify custom metal manufacturing?
For a comparable custom-manufacturing quotation, send the drawing revision or sample, material specification, critical tolerances, process preference, finish, heat treatment, inspection plan, marking, prototype quantity, annual demand, packing and target timing.
Review the process
Describe material, geometry, mechanical requirements, finish and volume before selecting forging, casting, stamping or machining.
Define the program
State tooling expectations, prototype and annual quantities, inspection documents, packaging and delivery target.
INDEXABLE PROCUREMENT FIELDS
Information used to confirm the correct model.
These fields are reviewed item by item. They are not a substitute for the final quotation, applicable standard or engineering confirmation.
Technical input
Drawing revision, 3D model or physical sample with critical dimensions and tolerances identified.
Material and process
Material specification, forging, casting, stamping or machining preference and heat-treatment requirement.
Finish and inspection
Surface treatment, critical inspection points, test documents and marking requirement.
Commercial program
Prototype and annual quantities, packaging, destination, target timing and tooling expectations.
TYPES & CONFIGURATIONS

BUYER COMPARISON
Compare configurations before requesting prices.
This table defines the information needed for a comparable quotation; it does not replace the selected product standard or application review.
| Configuration | Typical purchasing context | State in the RFQ |
|---|---|---|
| Closed-die forging | Parts whose approved geometry, material, mechanical requirement and volume support a forging route. | Drawing, material, tolerances, heat treatment, tooling, inspection and annual quantity. |
| Precision casting | Parts whose geometry and material are reviewed as suitable for the selected casting process. | Drawing or model, material, tolerance, surface, test requirements, tooling and volume. |
| Stamping or machining | Sheet-metal or machined features reviewed against thickness, material, tolerance, tooling and production quantity. | Drawing, material or sheet thickness, critical dimensions, finish, inspection, quantity and packaging. |

PURCHASING FAQ
Before you request a quotation.
Final product suitability and commercial terms are confirmed against the selected model, application and order requirement.
What files are needed for a custom metal part quotation?+
Provide a controlled 2D drawing and, where available, a 3D model, material specification, tolerances, critical features, finish, inspection needs and quantity forecast.
How is forging compared with casting or stamping?+
Process selection depends on geometry, material, mechanical requirements, tolerances, surface requirement, tooling and expected quantity. ZECH reviews the supplied part before confirming a route.
Can ZECH work from a physical sample?+
A sample can support identification and discussion, but approved drawings, material, tolerances and acceptance criteria are still needed before production confirmation.
What quantities should be included in the RFQ?+
State prototype or trial quantity, first-order quantity and expected annual demand so tooling, process and packing can be reviewed on the same basis.
