About us

A machining partner that answers engineering questions before quoting

WenCNC Precision Manufacturing produces custom parts from drawings: CNC machining, sheet metal fabrication, surface finishing and inspection, delivered as one order.

What we do

We manufacture custom parts for customers who need them made correctly the first time: product development teams, machine builders, OEMs and equipment operators. The work covers 3, 4 and 5-axis CNC machining, CNC turning, sheet metal fabrication and finishing, from a single prototype to low-volume production.

The parts we are asked to make are usually the awkward ones — thin walls, tight datums, cosmetic surfaces, finishes that have to match between shipments, or geometry that cannot be reached in three axes. Those parts are decided at the planning stage, which is why an engineer reviews every RFQ before a price is issued.

How we work

Machining, sheet metal, finishing and inspection are planned as a single sequence. That avoids the usual failure mode of splitting a part across suppliers: a bend allowance agreed between one vendor and rejected by the next, or a coating that closes a thread because nobody owned the masking decision.

  • One contact. Quotation, engineering questions and delivery documents come from the same team.
  • Written quotations. Unit price, tooling (if any), lead time and shipping terms are confirmed in writing.
  • Documented quality. Inspection plans, dimensional reports, material and finish certificates on request.
  • Prototype-to-production continuity. The process that passes validation is the process that runs the batch.

What we need from you

A drawing or 3D model, the material, the quantity, and the finish. Anything else — a critical tolerance, a cosmetic surface, a documentation requirement — should be written down at the RFQ stage so it is priced and planned for, rather than discovered at inspection.

Languages and communication

We work in English and Chinese. Technical drawings, tolerance callouts and inspection reports are handled in English, and we will confirm our understanding of any ambiguous requirement in writing before production starts.

Why customers keep their parts with us

Engineering review before machining

Every RFQ is reviewed by an engineer for manufacturability, tolerance cost and material alternatives, so you know where the cost is before you commit.

Prototype to production continuity

The same process, fixtures and inspection plan scale from 1 piece to low-volume runs, so the part that passes validation is the part that ships.

Tight tolerance control

Parallel-machined fixtures and in-process inspection on 3, 4 and 5-axis centres hold accurate datums across the batch.

Wide material availability

Aluminium, stainless steel, carbon steel, brass, copper, titanium and engineering plastics are sourced against your specification, with certificates on request.

Finishing in the same supply chain

Anodizing, powder coating, plating, polishing and painting are managed together with machining, so colour and appearance stay consistent between batches.

Clear communication

One English-speaking contact for quoting, engineering questions, production status and shipping documents — with proactive updates when something changes.

How an order runs

  1. 1

    Send drawings

    Upload STEP, IGES, DXF, PDF or native CAD files with material, finish and quantity.

  2. 2

    Engineering review

    We check manufacturability, tolerances and finish, and suggest alternatives where they reduce cost.

  3. 3

    Quote and approve

    You receive a written quotation with unit price, tooling, lead time and shipping terms.

  4. 4

    Production and inspection

    Machining, fabrication and finishing run against an agreed inspection plan.

  5. 5

    Ship and support

    Parts are packed, documented and shipped; we stay available for any follow-up revision.
