Product Assembly
At Cranfield Group, product assembly transforms injection moulded parts into functional, finished products. Our assembly services represent the crucial final steps that add value, ensure quality, and deliver solutions ready for immediate use. Whether you need simple two-part assemblies or complex multi-component products, we manage the entire process with the same precision we apply to moulding.
Our assembly capabilities complement our injection moulding services, providing a true single-source solution. We take ownership of your assembly challenges, managing everything from component compatibility through to final testing, ensuring your products are built right first time. This integrated approach eliminates the logistics complexity of multiple suppliers whilst maintaining quality control throughout the assembly process.

- Quality Integration – In-process inspection and functional testing at every stage, catching issues before they become problems.
- Reduced Total Cost – Eliminating inter-supplier transport, reducing inventory, and streamlining quality management delivers real savings.
- Problem-Solving Approach – When assembly challenges arise, we find solutions quickly, keeping your production moving.
Our Product Assembly Capabilities
- Joining Technologies – We employ various methods to create permanent and semi-permanent connections between components. From welding technologies that create seamless joints to mechanical fastening systems, we select the most appropriate method for your product requirements and production volumes.
- Component Integration – Our assembly processes bring together multiple elements to create functional products. This includes integrating metal inserts with plastic components, combining rigid and flexible materials, and incorporating bought-in components such as electronics or mechanical parts into your assemblies.
- Quality-Controlled Assembly – Every assembly operation follows documented procedures to ensure consistency. Whether assembling two components or managing complex multi-part products, we maintain precision throughout the process with appropriate testing and inspection at each stage.
- Flexible Assembly Solutions – Our assembly capabilities scale from manual operations for intricate or low-volume products to semi-automated processes for higher volumes. We adapt our approach based on product complexity, volume requirements, and quality specifications, always focusing on delivering reliable, cost-effective assembly solutions.
