How do we move from a drawing to repeat production?
- Define the part: provide the drawing revision, material requirements, tolerances, operating conditions and quantities.
- Review the design: agree the geometry, material and inspection requirements with our engineering team.
- Establish the production specification: identify any prototype, sample or validation work needed before release.
- Plan supply: agree production quantities, documentation and delivery requirements for the quotation.
See our CAD design capability and guide to manufacturing from drawings. Batch size, lead time and acceptance criteria are confirmed for each project.
