Sub-Assembly & Full System Build
From board to box โ we build the bigger picture.
At SMS, our full system build, or box build, is where your vision truly comes to life. This isn’t just assembly; it’s a seamless process that delivers a complete solution, ready to impress your customers and capture your market.



We support everything from electro-mechanical integration to full product build, packaging, and labelling, with total traceability throughout. Our flexible lines and modular workflows allow us to scale to your requirements, reduce handoffs, and maintain full visibility through each step of the process.
The result? Reduced lead times, lower risk, and a manufacturing partner whoโs as invested in the finished product as you are.
