Request a quote

What to send with your drawing

A complete request gets a usable price the first time. Missing information is the main reason a quote comes back with questions instead of a number.

Checklist

  1. 2D drawing (PDF/DWG) and 3D model (STEP/IGES/X_T) if available
  2. Material grade, or the function if the material is still open
  3. Quantity for the first order and the expected annual volume
  4. Critical tolerances and the features they apply to
  5. Surface finish and colour, plus which faces must be masked
  6. Assembly context — what the part mates with, and how
  7. Target date and destination country for shipping

Files can be sent by email or WeChat. NDA available on request; drawings are not shared outside the quoting team.

Accepted files: STEP, IGES, X_T, DWG, DXF, PDF, ZIP. Photos of a sample part work if there is no drawing, but the quote will carry a note about assumed dimensions.

What happens after you send

  1. 01

    Review

    We check geometry, tolerance stack-up, material and finishing, and reply the same working day with any question that would change the price.

  2. 02

    Quote

    A price broken down by material, machining, finishing and inspection, with lead time and shipping terms. Valid for 30 days.

  3. 03

    Sample

    On approval we cut the first article, measure the critical characteristics and send the part with the inspection report.

Questions buyers ask before the first order

What is the minimum order quantity?

One piece. Prototypes are quoted with the set-up and programming cost included, so the piece price is naturally higher than a batch price. There is no mould or tooling charge for machined parts.

How fast can I get a quote and a sample?

Quotes are typically returned within 24 hours of a complete drawing package. Samples usually take 3–7 working days, depending on material availability, the number of operations and whether finishing is sub-contracted.

Can you work to ±0.01 mm?

±0.01 mm is a realistic typical tolerance on milled and turned features, and ±0.005 mm is achievable on turned diameters after review. Whether a specific tolerance is feasible depends on feature geometry, material and set-up, so it is confirmed at drawing review rather than promised up front.

Do you supply material and finishing certificates?

Yes. Material certificates are available for the grades we purchase, and first article inspection reports are issued on request. Finishing is carried out by qualified partners and their certificates can be supplied with the batch.

How do you handle shipping and payment for overseas orders?

Export packing is quoted with the parts. Shipping is arranged by air, sea or express according to the Incoterm agreed at quotation. Payment terms are agreed per order, with a deposit for first-time production runs.

Can you keep our drawings confidential?

Yes. Drawings are held by the quoting and engineering team only, are not published, and are not shared with third parties except the finishing partners required to complete the order. An NDA can be signed before files are exchanged.
