How we work

From your PDF
to series delivery.

Four steps from drawing to delivery. You always know where your part stands and who will call if something needs clarifying.

  1. 01

    Enquiry with drawing

    Send DWG, STEP, PDF or DXF with quantity and target date — through the form or by email.

    Dauer≤ 2 Werktage
  2. 02

    Technical review

    Luca and Wilhelm check feasibility, material, clamping and process. You receive a quote without obligation with unit price, tooling cost and delivery date.

    Dauer48 hours
  3. 03

    First article

    First setup, sample part, measurement report. Only once the first article is approved does the series start.

    Dauer1 – 3 Wochen
  4. 04

    Series production

    Repeatable to the same programme and the same fixtures. Documented, traceable, on schedule.
