1. Files
The best starting point is the 3D model and the 2D drawing of the part together. The model defines the geometry; the drawing defines tolerances, critical dimensions and surface requirements.
- 3D model: STEP (preferred) or IGES
- 2D drawing: PDF, DWG or DXF, with tolerances, critical dimensions, weld and surface symbols
- For assemblies: parts list and assembly drawing
- Put several files into one ZIP file
The quote form accepts files up to 3 MB. Send larger files to web@tdmtr.com after submitting the form; just mention your company and the part name in the email.
2. Material and thickness
Material and thickness drive both price and process choice. State the material standard or mill grade (for example Erdemir 7336) and the sheet thickness; for tube parts, give diameter × wall thickness. We work with sheet from 0.5 to 20 mm.
If an equivalent material is acceptable, say so; it can shorten material lead time.
3. Volumes and timing
Annual volume decides whether series production with dedicated dies or die-less prototype and small-batch methods make sense. Include:
- Annual volume and expected project life
- Batch size per order
- Number of prototypes or samples
- Target dates for samples and start of production
4. Scope of work
Tell us how far you want us to take the part. Sheet metal forming, welding and assembly, CNC tube bending, powder and wet painting and packaging can all be done in the same plant.
- Tooling: is a new die needed, or will an existing die be used?
- Surface: paint type and colour code
- Assembly: who supplies fasteners and bought-in parts?
- Shipping: packaging and delivery terms
5. Quality requirements
In automotive projects the quality expectations should be clear from the start. If there is a PPAP level, required measurement reports, special characteristics or customer-specific standards, send them with the request. We run PPAP, 8D, SPC and MSA within our ISO 9001:2015 certified quality management system.
What happens after you send it?
- Your request goes straight to our engineering team.
- The team checks manufacturability, material and process route, and contacts you if anything is missing.
- We send the quote in about 7 business days.
How a die-formed sheet metal part moves from quote to series production is covered in our guide from die to series production.
