Project Process

StepWhat Happens
1. Drawing or sample reviewWe review the customer drawing, sample photo, or written requirements before quotation.
2. Quotation reviewMaterial, dimensions, load requirement, quantity, and application are reviewed before quotation direction.
3. Sample productionSamples can be produced from production tooling for customer approval, depending on project requirements.
4. First article inspectionThe first sample run is checked against drawing with written inspection records.
5. Process lock & repeat supplyApproved sample settings carry forward unchanged into volume production. Any process change requires re-approval.
6. Inspection & shipmentParts are inspected before shipment. Packing list and inspection report included. Material certificates available on request.

Anonymous Spring Project Example

A customer needed a custom spring for an OEM assembly and provided drawing-based requirements for review. The project was handled through drawing review, material discussion, sample production, and approval before moving toward repeat production. The customer name and detailed part dimensions are not disclosed due to confidentiality.
