Box Build Assembly & Electromechanical Integration
Complete turnkey box build assembly for Australian OEMs. We integrate your cable harnesses, PCBs, and electronic components into finished, tested enclosures — ready for deployment. From 1 prototype to 50,000+ units per year.
What is Box Build Assembly?
Box build assembly — also known as electromechanical assembly or systems integration — is the final step in contract manufacturing where individual components are brought together into a complete, functional product. It takes your cable assemblies, wire harnesses, printed circuit boards, power supplies, mechanical brackets, and enclosures, and integrates them into a finished unit that is tested, labelled, and ready for installation or sale.
For Australian OEMs and product companies, box build assembly eliminates the complexity of managing multiple suppliers and assembly steps. Instead of receiving loose components and assembling them yourself, you receive a complete, tested product — reducing your overhead, accelerating time-to-market, and improving quality consistency.
Our box build services are particularly valued by customers in mining, industrial automation, medical devices, and energy systems where reliability, environmental sealing, and comprehensive testing are non-negotiable requirements.
"Box build assembly is where everything comes together. Our customers tell us the biggest value isn't just the assembly itself — it's the elimination of coordination headaches. When one supplier handles your cable harnesses, PCB integration, and final enclosure assembly, the finger-pointing between vendors disappears entirely."

Box Build vs. Cable Assembly: When to Upgrade
Cable Assembly Only
Best when you have in-house assembly capability and just need wiring sub-assemblies.
- You receive individual cable harnesses
- Your team handles final integration
- Multiple vendors ship to your facility
- You manage component inventory
Box Build Assembly
Best when you want a finished, tested product delivered ready for installation or sale.
- You receive a complete, tested unit
- Single supplier handles everything
- Reduces your assembly floor space needs
- We manage the full supply chain
Our Box Build Process
Design Review & DFM Analysis
Our engineering team reviews your design package — schematics, BOMs, mechanical drawings, and assembly instructions. We provide Design for Manufacturability (DFM) feedback to optimise assembly efficiency, reduce cost, and prevent production issues before they occur.
Component Sourcing & Kitting
We procure all components from authorised distributors and approved suppliers. Each kit is verified against your BOM with incoming quality inspection, moisture sensitivity handling, and full traceability documentation.
Sub-Assembly Manufacturing
Cable harnesses, wire assemblies, and PCB assemblies are manufactured in-house or sourced from our certified facilities. Sub-assemblies undergo intermediate quality checks before integration.
Mechanical & Electromechanical Integration
Components are assembled into the enclosure following documented work instructions. This includes PCB mounting, harness routing, connector termination, and mechanical fastening with calibrated tools.
Electrical Testing & Functional Verification
Every unit undergoes 100% electrical testing — continuity, hi-pot, insulation resistance, and power-on functional testing. Custom test fixtures ensure repeatable, reliable results across production runs.
Final Inspection, Packaging & Shipping
Visual inspection against IPC standards, cosmetic verification, labelling, and serial number assignment. Units are packaged with ESD and shock protection, then shipped directly to your Australian or international facility.
Why Australian OEMs Choose Our Box Build Service
Single Point of Accountability
One supplier, one purchase order, one quality system. No more coordinating between PCB vendors, enclosure fabricators, and assembly houses.
Reduce Overhead & Floor Space
Eliminate the need for assembly technicians, test equipment, and dedicated production space at your facility.
Faster Time to Market
Parallel sourcing and integrated manufacturing compress your production timeline compared to sequential in-house assembly.
Scalable Production
From engineering prototypes to volume production — scale up and down without capital investment in tooling or workforce.
Australian Engineering Support
Melbourne-based project management with direct communication to our production facilities. No timezone headaches.
"The transition from buying cable assemblies to full box build is a natural evolution for growing product companies. You focus on product design and sales while we handle the entire manufacturing chain. That's when our customers see the real productivity gains."

Frequently Asked Questions
What is box build assembly?
Box build assembly (also called electromechanical assembly or systems integration) is the process of integrating all electronic and mechanical components — PCBs, cable harnesses, connectors, power supplies, and mechanical parts — into a finished enclosure. The result is a complete, tested, ready-to-install product or sub-system. It goes beyond simple cable assembly by delivering a fully functional unit rather than individual components.
What is the minimum order quantity for box build assembly?
We offer box build assembly starting from 1 prototype unit. There is no minimum order requirement. Whether you need a single prototype for design validation or 50,000+ production units per year, we scale our production process to match your volume requirements. Prototype builds typically take 3-4 weeks.
Can you source all components for the box build?
Yes, we offer full turnkey box build assembly where we procure all components — enclosures, PCBs, connectors, cables, fasteners, labels, and packaging materials — from our network of authorised distributors. We also support consigned builds where you supply specific components. All sourced components include full traceability documentation.
What testing is performed on box build assemblies?
Every box build assembly undergoes 100% electrical testing including continuity, hi-pot (dielectric withstand), and insulation resistance testing. We also perform functional power-on testing, I/O verification, firmware loading where required, and visual inspection to IPC/WHMA-A-620 standards. Custom test protocols can be developed for your specific requirements.
Do you provide box build assembly for harsh environments?
Absolutely. We specialise in ruggedised box build assemblies for Australian mining, marine, and outdoor applications. We deliver enclosures rated IP54 to IP67 with proper gasket sealing, cable glands rated for dust and water ingress, conformal coating on PCBs, and temperature-rated components for -40°C to +85°C operation.
How does box build differ from cable assembly services?
Cable assembly produces individual wiring assemblies — cables with connectors. Box build takes it further by integrating those cable assemblies, along with PCBs, power supplies, and mechanical components, into a complete enclosed system. Think of cable assembly as producing ingredients, while box build delivers the finished meal. Many of our customers start with cable assemblies and graduate to box build as their products mature.
What certifications do your box build facilities hold?
Our manufacturing facilities are ISO 9001:2015 certified, and our automotive-grade facilities hold IATF 16949:2016 certification. We manufacture to IPC/WHMA-A-620 workmanship standards. For medical device customers, we can support ISO 13485 documentation and traceability requirements. All assemblies comply with RoHS and REACH directives.
