Precision Machining & Contract Assembly Services

Marcus provides in-house CNC machining using more than 20 machining centres, including 3-axis, 4-axis, and 5-axis VMCs, Turn-Mill centres, and Drill-Tap centres. The team machines aluminium, zinc, and magnesium components to tolerances as tight as ±0.005mm on critical mating faces, bearing bores, threaded interfaces, and sealing surfaces, using toolpaths programmed directly from customer 3D CAD models.

Marcus supports mechanical, electro-mechanical, and semi-automated contract assembly for prototypes through high-volume OEM production. Capabilities include cable crimping, connector integration, switches, sensor housings, ultrasonic welding, crimping, plastic over moulding, inline inspection, functional testing, packaging, labelling, and fulfillment to customer standards, allowing customers to receive ready-to-install finished products from one supplier.

Marcus supports customers in electronics, aerospace, energy, industrial manufacturing, healthcare, EV, and automotive sectors. Its machining and assembly capabilities are suited to programs that require tight tolerances, validated quality systems, and dependable repeatability. This makes Marcus a strong fit for OEMs and Tier-1 suppliers seeking a manufacturing partner for both precision components and finished sub-assemblies.

Marcus operates under IATF 16949:2016 and ISO 9001 certified processes. These systems support disciplined quality planning, inspection, traceability, and continuous improvement across machining and assembly operations. Marcus also applies industry-standard methods such as DFM, APQP, PPAP, and FAIR, helping customers manage launch requirements, documentation needs, and ongoing production quality with greater confidence.

Yes. Marcus supports low-volume prototypes, pilot runs, and high-volume OEM production through a mix of in-house machining, dedicated assembly lines, and tooling support. Its semi-automated assembly lines and structured new product development approach help customers move from early validation to scaled production while maintaining process consistency, inspection control, and readiness for repeat manufacturing.

Yes. Marcus offers co-located surface finishing and treatment services that can be integrated with machined and assembled parts. Available processes include powder coating, wet painting, chrome and nickel electroplating, anodising, PVD coating, blasting, polishing, resin impregnation, chromation, and heat treatment. Finished parts are tested to standards such as ASTM B117, XRF coating thickness, and adhesion cross-hatch requirements.

Marcus helps reduce supply chain complexity by combining machining, assembly, tooling, finishing, and selected partner-network manufacturing under one coordinated source. Instead of managing multiple vendors for separate operations, customers can streamline communication, quality oversight, and delivery planning through a single partner. This approach can shorten lead times, reduce handoff risks, and improve overall program visibility.

For the most accurate review, provide part drawings, 3D CAD files, material specifications, tolerance requirements, annual volume estimates, assembly details, finishing needs, testing requirements, and any packaging or labeling standards. If the project is in development, Marcus can also support DFM discussions and tooling considerations, helping identify manufacturability improvements before production commitments are finalized.
