Added value for procurement and engineering
For procurement
Predictable costs. One supplier.
- One point of contact from analysis to series part
- Calculation before engineering – know the costs before you commit
- Price scales for batch sizes and manufacturing processes compared
- Security of supply through stocking, call-offs and framework agreements
For engineering
Fits and lasts like the original.
- Complete part capture – geometry, material, function, wear
- 3D CAD and 2D drawings with tolerances and material specifications
- Known weak points eliminated by design on request
- First article inspection with measurement report and fitting test
Process
From original part to series part – in six steps.
With clear results after every step and a reliable cost statement before engineering begins.
