Whether it is the simple enclosure of a PCB assembly within two plastic mouldings or the fabrication of a complex metal card frame, CEMS has the necessary skills and equipment to provide their customers with a high level box build service.


CEMS has extensive experience of the manufacture of Mechatronics based systems. The moving harmony of mechanical parts, electronic controls and interlocks demands a precision mechanical assembly skill-set coupled with competence in electronic assembly and wiring.

Low Cost Sourcing

CEMS have extensive experience of off-shore sourcing, which offers the benefits of attractively priced low cost sources for PCBs, sheet metal fabrications, CNC machined metal parts, plastic mouldings and cable assemblies.

Cable Assemblies

CEMS is capable of producing cable assemblies from the simplest form of a few wires stripped, twisted and tinned at each end to large and complex bundles of different ID marked wires and cables, laced and terminated on large military connectors, with many years of experience in the field. CEMS produces, amongst a wide range of critical applications, wiring harnesses for civil and military aircraft including the long established Wire Wrap technology.


CEMS manufactures a wide range of sub-assemblies including PCBs with various brackets and fitments, chassis containing PCBs, backplane and PSU, to precision machined metal parts containing sophisticated state-of-the-art electronics.

Subsequent full system integration times and costs are reduced by sourcing pre-tested sub-assemblies and at CEMS there is a wealth of experience and investment aimed at satisfying that requirement.
