Precision CNC Machining & Manufacturing Services

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

Marcus supports customers in automotive, EV, aerospace, electronics, healthcare, energy, and broader industrial manufacturing. Its capabilities are suited to both structural and precision components, as well as finished sub-assemblies. Because machining, assembly, tooling, and finishing are coordinated under one quality framework, the company can support programs that require repeatability, documentation, and production scalability.

Yes. Marcus supports early-stage prototyping as well as ongoing OEM and Tier-1 production programs. Prototype support includes DFM review, simulation, rapid prototyping, T0 and T1 trials, and validation activities. Once the design is approved, the same manufacturing ecosystem can support scaled production with controlled tooling, inspection plans, and documented quality processes.

Marcus machines aluminium, zinc, and magnesium components in-house and also supports broader manufacturing requirements through its integrated and partner-led capabilities. Depending on the process, programs may include aluminium alloys, zinc alloys, magnesium, steels, copper alloys, plastics, and forged materials. This allows customers to consolidate multiple component types through a single manufacturing partner.

Marcus operates under IATF 16949:2016 and ISO 9001 certified quality systems. These standards support disciplined process control, traceability, inspection planning, and continuous improvement. In addition, the company applies industry-standard methods such as DFM, APQP, PPAP, and FAIR, which are especially important for automotive, aerospace, and other quality-sensitive manufacturing programs.

Yes. Marcus offers in-house surface finishing and treatment services alongside mechanical and electro-mechanical assembly. Available finishing processes include anodising, plating, powder coating, painting, blasting, polishing, and heat treatment. Assembly capabilities include sub-system integration, cable and connector work, ultrasonic welding, crimping, inline inspection, and functional testing, helping customers receive ready-to-install parts or modules.

Dimensional consistency is maintained through direct CAD-based programming, custom jigs located from defined datums, controlled machining processes, and advanced inspection methods. Marcus also uses inline inspection and metrology tools such as CMM systems to verify critical features throughout production. This approach helps maintain repeatability across batches and supports demanding tolerance requirements on precision components.

Yes. Marcus serves global customers across regions including Australia, the United Kingdom, North America, the Middle East, Italy, Mexico, Vietnam, and India. In addition to its headquarters in Coimbatore, the company works with certified supply chain partners across India, Vietnam, and China. This broader footprint helps support flexible sourcing, scalable production, and international program requirements.
