Automotive Sub-Assembly & Prototyping Services

These services typically cover design-for-manufacture review, rapid prototyping, tooling support, CNC machining, mechanical assembly, electro-mechanical assembly, trial builds, and validation testing. At Marcus, programs can also include jigs and fixtures, T0 and T1 trials, inline inspection, and documentation such as APQP, PPAP, and FAIR to support a smoother transition into production.

Yes. Marcus supports low-volume prototype builds as well as high-volume production programs. The company uses in-house tooling, machining, and semi-automated assembly lines to scale output based on program stage. This allows customers to validate early designs, refine assemblies, and then move into repeatable production without changing suppliers mid-program.

While this page focuses on automotive applications, Marcus also supports EV, aerospace, electronics, healthcare, energy, and industrial manufacturing programs. Many of the same capabilities, such as electro-mechanical assembly, precision machining, and validated quality processes, are well suited to industries that require tight tolerances, traceability, and dependable functional performance.

Marcus operates under IATF 16949:2016 and ISO 9001 certified processes. Quality support includes DFM review, APQP, PPAP, FAIR, inline inspection, functional testing, and advanced metrology such as CMM-based verification. These controls help ensure prototype and sub-assembly programs meet automotive expectations for consistency, documentation, and launch readiness.

Yes. Marcus produces electro-mechanical assemblies that combine mechanical components with electronic elements such as connectors, switches, cable crimps, and sensor housings. In-line electrical testing is used to validate performance before shipment. This makes the service suitable for functional automotive modules that require both mechanical fit and electrical reliability.

Yes. Marcus has an in-house tool room that supports die, mould, jig, and fixture design, fabrication, maintenance, and engineering changes. The team also conducts T0 and T1 trials and supports rapid prototyping. Keeping tooling development in-house improves control over timelines, revisions, and validation during early-stage automotive programs.

Marcus operates more than 20 in-house CNC machining centres, including 3, 4, and 5-axis equipment. Critical features can be machined to tolerances of ±0.005 mm on mating faces, bores, threaded interfaces, and sealing surfaces. Datum-based fixturing and CAD-driven toolpaths help maintain repeatability across prototype and production runs.

Yes. Marcus is positioned to consolidate multiple manufacturing stages under one partner, including tooling, die casting, machining, finishing, plastic over moulding, and assembly. This single-source approach helps reduce supplier coordination, shorten lead times, improve accountability, and simplify quality management for automotive OEM and Tier-1 programs.
