Mechanical Assembly
Precision assembly of metallic sub-systems using die-cast, machined, stamped, and forged parts, with inline inspection, ultrasonic welding, crimping, and functional verification for production-ready automotive assemblies.
Marcus delivers automotive component assembly services backed by 45+ years of manufacturing experience, combining mechanical, electro-mechanical, plastic over moulding, testing, and finishing under one quality-controlled supply partner. From prototype builds to OEM production, customers gain shorter lead times, certified processes, and ready-to-install assemblies supported from Coimbatore for global programs.

Integrated assembly solutions for automotive modules, sub-assemblies, testing, and production support under one certified manufacturing partner.
Precision assembly of metallic sub-systems using die-cast, machined, stamped, and forged parts, with inline inspection, ultrasonic welding, crimping, and functional verification for production-ready automotive assemblies.
Assembly of modules combining mechanical parts with electronics, including cable crimping, connector integration, switches, sensor housings, and in-line electrical testing under certified quality processes.
Dedicated semi-automated assembly lines support low-volume prototypes through high-volume OEM production, with packaging, labeling, and fulfillment completed to customer specifications.
In-house plastic over moulding integrates moulded components directly into mechanical and hybrid assemblies, helping reduce sourcing complexity and improve fit, function, and production efficiency.
Structured NPD support moves automotive assemblies from design review to production readiness through DFM, prototyping, trials, validation, and APQP and PPAP-driven launch preparation.
In-house CNC machining delivers precision features and critical tolerances on mating faces, bores, threads, and sealing surfaces before final assembly and testing.

The process starts with a detailed review of drawings, CAD data, specifications, and quality expectations. Marcus aligns assembly methods, materials, and inspection plans early so automotive programs move forward with fewer delays and clearer production controls.
