Before you release the project
- Define the function, environment and the question this batch must answer.
- Specify material grade, geometry, quantity, finish and the dimensions that control fit.
- Agree the inspection method and the evidence required to accept the parts.
- Record the drawing revision and approval before production begins.
Common planning questions
Can I choose a material by name alone?
Specify the grade, condition, process and required properties. A shared polymer or alloy family name does not establish identical performance.
Which material records should I request?
Request the records relevant to the project, such as grade identification, material certificates, property data or compliance declarations, and confirm how each relates to the supplied parts.
Move from guidance to a reviewed project
Send the CAD model and drawing with material, quantity, finish and inspection requirements. Use the relevant service page to review the available manufacturing route.
