How we work

From spec to delivery.

No rigid process — we adapt to your project.

1
Spec & Consultation — Analysis of your requirements: installation context, environmental conditions, standards, quantities, target unit cost.
2
Development & Design — Schematic derivation, bill of materials, 3D cable routing, material selection per operating conditions.
3
First Samples & Approval — Prototype with first-sample test report. Iterative optimization until customer approval.
4
Series Production — Laser soldering, crimping with force-distance monitoring, automatic laser stripping. All in our own factory.
5
100% Final Inspection — Continuity testing, insulation testing, high-voltage testing, visual inspection. Every single unit.
6
Warehouse FrankfurtDelivery from Frankfurt warehouse — Just-in-time call-offs, kanban systems, individual packaging per customer specification.
Mainstar delivered our first samples within three weeks — including test report. After one iteration the harness was series-ready. That saves us months compared to other suppliers.
