Why partner with us

We supply engineered subcomponents and subassemblies from prototype to series ramp. Expect tight tolerances, clean documentation (FAI/FAIR/PPAP), and stable delivery programs (Kanban, VMI, call-offs). Your drawings and 3D models become dependable modules—build-to-print or build-to-spec—with manufacturability feedback up front.

  • Predictable lead times with expedite options

  • Quality you can audit: ISO 9001 workflows, full metrology, 3.1 material certs

  • Data security: NDA/NNN, controlled access, revision control

  • EU-centric logistics: Switzerland/DACH operations, Incoterms EXW/FCA/DAP/DDP

Packaging, labeling & logistics

ESD-safe packing, protective foams and trays, barcode/QR serialization, kitting by work order, consolidated shipments. EU customs paperwork (HS codes, EORI) and shipments under EXW/FCA/DAP/DDP. Consignment stock and local buffer options available.

Supply models

  • Prototype → pre-series → series ramp

  • Blanket orders with call-offs, Kanban/VMI, EDI/MRP integrations

Industries we support

Medical devices, aerospace & defense, automotive & e-mobility, industrial equipment, robotics & automation, consumer electronics, lab instruments, marine, energy, oil & gas, chemical processing, food & beverage equipment.

Engagement model

  1. Share your package: STEP + drawings (GD&T), BOM, annual volume/EAU, target lead time, critical features.

  2. DFM & quotation: risks, alternates, and pricing across standard vs. expedite lanes.

  3. Pilot lot / PPAP: T0/T1, inspection reports, capability data, packaging spec.

  4. Release & supply: blanket/kanban setup, labeling, delivery cadence, change control (ECR/ECO).
