ISO-CERTIFIED · IP-PROTECTED · BRITISH-MANAGED

Precision product assembly in China, with built-in IP protection.

Custom contract assembly with a focus on quality, transparency, and IP security. A British-owned and managed facility in Zhuhai, backed by the C2W Group's 20 years of China manufacturing heritage.

Your Partner for Contract Assembly in China

A trusted partner for IP-sensitive, complex builds.

Shield Works operates out of a modern 100,000 sq ft facility in the heart of Zhuhai, a key manufacturing hub in China's Greater Bay Area. As a British-owned and managed enterprise, we combine Western standards of service with on-the-ground manufacturing expertise to run high-quality, IP-secure assembly.

Our facility includes dedicated assembly rooms, semi-automated and automated assembly lines, ESD-controlled zones for electronics, private fingerprint-access rooms for high-security projects, and smart software systems that offer clients real-time oversight of their production line. We assemble for companies that cannot afford a leaked design or a failed batch. IP protection and quality control sit at the front of every line, not bolted on at the end.

SMT and PCB assembly, through-hole work, and cable and wire harnesses, checked in line so every board is verified as it is built.

Already in production elsewhere? We disassemble, rebrand and repackage existing stock to your latest spec.

Before a unit is built, our DFX team pressure-tests the design, so cost, tooling and quality risks are caught on paper, not on the line.

Our Contract Assembly Approach

From project brief to shipped units, in three managed steps.

  1. Tailored project planning

    Every contract assembly project begins with your product. Whether your build is manual assembly by trained technicians or requires automation, we assess your requirements and determine the most effective process to bring it to life.

  2. Agile, scalable execution

    Our team is adaptable and continuously evolving. We regularly add new training, equipment, and specialised processes, so we can align quickly with your needs, whether that is a new in-house design, reassembly with firmware updates, or transitioning your existing operations from another facility.

  3. Quality assurance & real-time data

    Experienced supervisors oversee every stage. Our software systems provide live reporting and real-time visibility into your production, with precise quality checks and strict timeline adherence, so you stay focused on your core business.

Black-Box Assembly

Built-in IP protection, by structure.

Many of the products we assemble coordinate multiple suppliers and sensitive technologies. For those builds, Shield Works runs a true black-box environment, where only you and our vetted upper management ever see the full picture.

Every build

  • Only you and vetted upper management know the full product
  • Operators only see the components for their specific task
  • Segmented workflows with secure, role-restricted access

IP-sensitive builds

  • Dedicated private rooms with on-site CCTV security monitoring
  • Fingerprint-access controls limit entry to essential personnel
  • Binding NDAs signed with a British-owned and managed company

Why Choose Shield Works

In-house assembly, or Shield Works.

If you run assembly internally and feel the squeeze on cost, scale, or flexibility, transitioning to Shield Works gives you a controlled, cost-efficient environment that improves visibility, accelerates timelines, and lifts product quality.

Managing assembly in-house

  • Rising fixed costs and overhead
  • Limited ability to scale with demand
  • Capital tied up in space and equipment
  • Longer lead times and tighter bottlenecks
  • Quality control resting entirely on your team
  • Full supply-chain complexity carried in-house

  • Variable cost that flexes with demand
  • Scale up or down by run, with no capex
  • Internal space and headcount freed up
  • Just-in-time deliveries and shorter lead times
  • Dual-layer QC, verified independently by C2W Group
  • IP protection with dedicated, access-controlled zones
  • 100% British owned and managed, fluent English
  • Transparent, real-time production tracking and reporting
  • Flexible support for urgent orders and late-stage design changes
  • 20 years of China manufacturing experience through the C2W Group
  • Integrated upstream sourcing and downstream logistics

Frequently Asked

Contract assembly, answered.

What is contract assembly?

Contract assembly means outsourcing the build of your product to a specialist partner. Shield Works receives your components, or manages their supply, assembles to your specification under documented quality control, and ships finished, inspected units. You keep full ownership of the design and IP throughout.

How does Shield Works protect my IP during assembly?

Through a black-box model. Operators only see their assigned task, sensitive sub-assemblies are compartmentalised, and suppliers never receive full designs. IP-sensitive builds run in fingerprint-access rooms under NDA. See the full IP protection model.

What production volumes do you handle?

From prototype builds and low-volume runs through to ongoing mid and high-volume production. We scale the line setup to your order profile rather than forcing a fixed minimum.

How is quality controlled?

Dual-layer QC. Shield Works runs internal incoming, in-process, and final quality checks against an agreed inspection plan. A quality engineer from the C2W Group, our parent company, then independently verifies the batch and reports directly to you. More on quality inspection and testing.

Why not go direct to a factory or use a freelance agent?

A direct factory optimises for its own throughput and rarely offers Western-standard QC, IP control, or transparent reporting. A freelance agent has no facility of its own. Shield Works is a British-owned facility with its own controlled floor, its own quality team, and a single point of accountability from brief to shipment.

Can you take over assembly from our current manufacturer?

Yes. We regularly transition existing operations into our facility, including reassembly with firmware updates and process improvements, with minimal disruption to your supply.

What is out of scope?

We assemble consumer electronics, industrial hardware, and mechanical and electromechanical products across plastics, metals, composites, and electronics. We do not handle clothing, footwear, cosmetics, chemicals, food, or pharmaceuticals, and we do not take on defence work of any kind, including weapons, munitions and explosives.

What happens after I submit a brief?

We look at your specification and parts list, assess fit, and reply to most enquiries within 24 hours. If it looks like a fit, we review the project in detail and put NDA and IP scoping in place, then set up a call to confirm fit before we come back with a proposal. All work runs under a paid engagement. Submit your project brief.
