Where the parts go

Parts for the machines that make things

  • Semiconductor equipment

    Hsinchu sits next to Taiwan’s chip fabs, and much of the supply chain here builds for the tools inside them: chamber fittings, wafer-handling brackets, gas-line blocks.

  • Automation & robotics

    End-of-arm tooling, gripper fingers, linear-axis plates, shafts and couplings. Short runs, frequent revisions.

  • Optics & instruments

    Lens mounts, sensor housings, adaptor rings, enclosures. Flatness and bore position over looks.

  • Medical & lab devices

    Fixtures, frames and manifolds for analysers and lab automation. Implants: not made here.

Routing

OP10–OP50

Five operations on every order. The batch does not run until the first-article report is approved.

  1. OP10

    Drawing review

    Every dimension, tolerance and note is read. A tolerance that is unclear or costly to hold gets a question before it gets a price.

  2. OP20

    Quotation

    Unit price for each quantity asked, lead time, Incoterm: EXW Hsinchu, FOB Taiwan port or DAP.

  3. OP30

    First article

    First parts measured against the drawing. Report sent for approval.

  4. OP40

    Production

    Batch run with in-process checks. Finishing in house or at a partner shop.

  5. OP50

    Inspection & shipping

    Final inspection, export packing, invoice and packing list. Tracking number by email.

  • Time zoneHsinchu runs on GMT+8, so a drawing sent on a European afternoon lands in the Hsinchu evening and the questions about it are waiting in a US inbox the next morning.

Request for quotation

Upload drawing for quote

Four fields required. Drawing review is OP10; the reply comes by email.

STEP, IGES, X_T, DWG, DXF, PDF or ZIP, 50 MB per file. A 3D model plus a 2D drawing with tolerances is the fastest to quote.

    One or more quantities. Each is priced.

    NDAOptional

    Datumline’s mutual NDA, or yours.

    Shared with the quoting engineers only.
