Engineering-Led Contract Manufacturer in China

Contract manufacturing of engineered components in China

A contract manufacturer that leads with engineering, not floor space

P&A International builds engineered parts and assemblies to specification — metalwork, machined components, plastics, castings and thermal hardware — through a vetted partner-factory network in China, every supplier ISO 9000 certified or better.

Founded as an engineering consultancy in 2008, we win work where drawings are demanding and evidence matters: DFM at quote, inspection data at delivery, one dedicated engineer in between.

What we build

Fabricated and machined metal components

Metalwork

Fabricated, machined, stamped and cast metal parts — see the metal hub for the full cluster.

Injection moulded plastic components

Plastics

Injection moulding from tooling to volume, with resins certified and tooling owned by you.

Thermal management heatsink components

Thermal

Heatsinks, heat pipes and cooling modules engineered to the duty.

Assembled mechanical product build

Assemblies

Multi-process builds kitted, tested and packed — one PO, one quality file.

The detailed service pages carry process depth; this page is the front door for build-to-spec work.

Engineering capability

  • Build-to-print across metal, plastic, casting, extrusion and thermal processes
  • DFM review on every quote; value engineering on standing programs
  • Tooling programs with customer ownership, storage and maintenance logging
  • Quality files: FAI, CMM, material certs, SPC, test reports as specified
  • Kitting, sub-assembly and tested-module delivery
  • Supply agreements: call-off scheduling, buffer stock, repeat batch pricing

Why engineers & buyers choose PA

For design engineers

Contract manufacturing fails at handover points — drawing to quote, quote to tool, tool to production. We staff those joints with engineers: the same person who challenged your tolerances at RFQ signs the first-article report.

For purchasing

Consolidation without opacity: itemised pricing per process, named partner classes, your tooling in your name, and inspection data with deliveries — the audit trail procurement wishes every CM provided.

3 easy steps to get started

1

Send the pack

Drawings, volumes, dates — partial packs are fine to start.

2

DFM + itemised quote

Feedback that improves the part, pricing you can compare line by line.

3

Pilot, then program

Evidence-backed first build, then supply on agreed terms.

Applications

Industrial equipment and automation hardware, energy and battery systems, lighting and electronics housings, transport and agritech components, medical hardware — engineered products where the spec is the contract.

Process depth: metal services, injection molding, aluminum die casting and thermal hardware. New to the model? Start at how we work.

Where we fit (and where we do not)

Honest fit assessment:

Engineered to drawing Core fit — tolerances, materials and evidence matter
Multi-process assemblies Strong fit — consolidation is the value
Catalogue commodities Poor fit — no engineering to add
Ultra-high-volume electronics Wrong network — we are mechanical-led

What to send us for a fast, accurate quote

The more of this you can share, the quicker we can return a proposed build plan and price:

  • Drawing pack or model set
  • Quantities: pilot, annual, program life
  • Quality documentation requirements
  • Assembly/test expectations
  • Target dates and delivery terms

Transferring from another CM? Say what broke — the proposal will address it specifically.

    Frequently asked questions

    Build-to-print or design support too?
    Both. Build-to-print is the core; design-for-manufacture input, material selection and value engineering are part of the service when you want them.
    Can you take over existing tooling?
    Yes — mould, die and fixture transfers with inspection, refurbishment and re-qualification are among our most common first projects.
    What volumes do you serve?
    Pilot batches through standing monthly programs. The network spans shops sized for one-offs and plants sized for millions — placement matches the volume.
    How do you price?
    Itemised: material, process, tooling, finishing, inspection, logistics — so comparisons are honest and cost-downs are traceable.
    What makes you different from other CMs?
    Engineering staffing at the failure points: DFM at quote, engineer-signed first articles, and one accountable person from RFQ to delivery — backed by an ISO 9000 certified or better network.
