FAQ
Questions we are asked before an inquiry.
If your requirement is not covered here, send the drawing or specification with the form above and it is answered against the actual project.
What should we send with the first inquiry?
The details that decide the process route are the most useful: a 2D drawing or 3D model, the material or grade, the application and working conditions, the expected quantity and the delivery market. Critical dimensions, tolerances and inspection requirements belong on the drawing, because they are what the finished part is checked against. If a drawing is not ready yet, a part number, equipment model or sample photo is enough to start.
Can you review a project that has no finished drawing yet?
Yes. Many projects start from a worn part, a sample photo, a part number or an equipment model. We use whatever is available to identify the geometry, the material and a possible process route, and we tell you which details are still missing before a quotation can be prepared.
Do we need an NDA before sending drawings?
That is your decision. Project material is used only for the technical review and the quotation. Send only what the first assessment needs, and say in the message if written confidentiality terms have to be agreed before drawings are released.
What happens after we send the form?
Each inquiry is read as a technical requirement rather than as a price request. If a dimension, material or application detail is unclear, it is asked back before a process route is proposed, and price and delivery are confirmed only once the technical review is complete.
Can we discuss a sample before mass production?
Yes. Describe the validation points your team needs to confirm, such as dimensions, fit, hardness, surface condition or inspection requirements, and the sample or trial scope is planned against them.
What if we have not decided on the material or casting process?
Send the application and the working conditions, and the review proposes the material families and process routes that fit. You do not need a fixed material or process before the first conversation.
