Mechanical Assembly (Product Assembly / Box Build)

At Precision Electronic Technologies, our mechanical assembly capability enables us to deliver complete electromechanical product builds, integrating electronics, cabling, and mechanical components into finished assemblies ready for testing and deployment.

A few years ago, Precision established a dedicated mechanical assembly facility to support customers requiring complete product builds. Due to the strong demand for this service, the facility has since been significantly expanded, enabling us to support a growing number of complex electromechanical assemblies from an increasing number of customers.

Our team specialises in high-complexity, low-to-medium volume products where workmanship, traceability, and disciplined processes are essential. This makes our capability particularly well suited but not limited to scientific instrumentation, industrial control systems, specialised monitoring equipment, sensing platforms, and other complex electronic products.

By combining PCB assembly, cable assembly, and mechanical integration under one roof, we provide customers with a streamlined manufacturing partner capable of delivering fully assembled products with consistent quality and traceability.

Mechanical Assembly Capability

Precision supports a wide range of mechanical and product assembly requirements, including:

Sub-Assembly Builds

Assembly of mechanical sub-systems and modules that integrate into larger products.

Enclosure & Housing Assembly

Assembly of product enclosures, housings, and structural components using controlled fastening processes.

Full Box-Build Assembly

Complete integration of mechanical and electronic components into finished products.

Cable Routing & Integration

Installation, routing, fastening, and management of internal cabling and harnesses.

Precision Mechanical Assembly

Careful assembly of complex electromechanical products requiring high workmanship standards and attention to detail.

Refurbishment & Recovery

Controlled refurbishment of existing products, including recovery of assemblies and recycling of materials where appropriate.

Integration with Electronics Assembly

Mechanical assembly at Precision is closely integrated with our PCB assembly services, allowing customers to consolidate multiple manufacturing stages with a single supplier.

This integration provides several advantages:

  • Better traceability across electronic and mechanical assemblies
  • Consistent build quality
  • Reduced logistics and handling between suppliers
  • More efficient product builds

We work best when involved early in the product lifecycle, supporting customers during prototyping, pre-production, and production ramp-up and full production.

Why Clients Choose Precision for Mechanical Assembly

Customers choose Precision because we are technically grounded, flexible, and genuinely invested in delivering high-quality outcomes.

Our mechanical assembly services are ideally suited to customers requiring high-complexity, low-to-medium volume product builds, where workmanship, traceability, and engineering collaboration are critical.

What sets us apart:

  •       Integrated PCBA, cable, and mechanical assembly under one roof
  •       Strong focus on high-mix, complex electromechanical products
  •       Engineering-supported builds, including practical design-for-assembly feedback
  •       Flexible production models supporting prototypes through to ongoing production
  •       Disciplined quality systems and full traceability
  •       A collaborative approach — we don’t just assemble; we work with customers to improve outcomes

Engineering Support

Our mechanical assembly capability is supported by a strong engineering function that works closely with customers throughout the product lifecycle.

We provide practical design-for-assembly (DFA) feedback, helping improve:

  •       Assembly efficiency
  •       Product reliability
  •       Component accessibility and fit
  •       Build repeatability

We add the most value when involved early, supporting prototype and pre-production builds through to full production.

Tooling, Fixtures & Assembly Environment

Our mechanical assembly area is equipped with tools and workstations designed to ensure repeatable and controlled assembly processes, including:

  • Manual and electric torque drivers
  • ESD-safe workstations and tools
  • Standard mechanical assembly tools
  • Assembly benches configured for repeatable builds
  • Inspection aids and visual reference standards

Where required, we develop simple product-specific jigs and fixtures to:

  • Hold housings securely during assembly
  • Ensure repeatable fastening and alignment
  • Protect sensitive PCB assemblies and cabling

This approach allows us to maintain consistent assembly quality across repeated builds.

Quality, Process & Workmanship

All mechanical assemblies are built using controlled documentation and defined assembly processes, supported by in-process and final inspections.

Typical quality checks include:

  • Visual condition inspection
  • Fastener presence and torque verification
  • Mechanical alignment checks
  • Housing closure and sealing verification
  • Cosmetic inspection and finish assessment

Mechanical assembly is fully integrated into our quality management system, including:

  • Product and material traceability
  • NCR and corrective action processes
  • Document control
  • Operator training systems

Our processes operate within an ISO 9001 quality framework and support ISO 13485 requirements where required by customers. These controls ensure repeatable builds and consistent product quality.

Volumes, Lead Times & Supply Chain

We support:

  •       Low-volume prototypes
  •       Small to medium production runs
  •       Ongoing production programs

Lead times depend on design complexity, material availability, tooling requirements, testing needs, and order volume.

Mechanical assembly materials may involve:

  • Customer-supplied materials
  • Precision-sourced components
  • Or a hybrid sourcing approach

Materials commonly handled include:

  • Sheet metal
  • Plastics
  • Aluminium
  • Mixed-material assemblies

Supplier quality and traceability are managed through incoming inspection, batch records, and lot tracking where required.

We work with trusted suppliers, maintain safety stock for key parts and offer alternative material options to manage supply chain risk and support long product life cycles.

Typical Products Assembled

Precision is particularly well-suited to the assembly of complex instrumentation, monitoring equipment, and specialised electronic products where reliability, traceability, and careful workmanship are critical.

Examples of the types of products we assemble include:

  • High-end multifunction measurement and control platforms
  • Mining and industrial monitoring systems
  • Environmental and underwater monitoring equipment
  • Agricultural and pollination sensing devices
  • Predictive maintenance systems for power infrastructure
  • Modular instrumentation platforms for research and development

These examples illustrate the types of complex products we support, while maintaining customer and product confidentiality.

Our mechanical assembly capability is well suited to a wide range of industries requiring precision electromechanical products and disciplined quality processes.

Ideal Applications for Mechanical Assembly

Precision’s mechanical assembly capability is best suited to complex electromechanical products where quality, traceability, and careful workmanship are critical.

  •       Typical applications include:
  •       Scientific and laboratory instrumentation
  •       Industrial monitoring and control equipment
  •       Environmental and field-deployed sensing systems
