Precision Investment Casting Parts Custom & OEM

Marcus supports investment castings in carbon steel, duplex steel, copper alloys, and super alloys. Material selection depends on the part’s strength, corrosion resistance, temperature exposure, and end-use environment. For OEM programmes, we can also align casting choices with downstream machining, finishing, and assembly requirements so the final component performs reliably in production and service.

Marcus supports investment cast parts up to 120 kg through its certified partner network. This range suits many industrial, automotive, aerospace, healthcare, and engineering applications that require complex geometry and good dimensional consistency. During review, we assess part size, wall thickness, tolerances, and finishing needs to confirm the most practical manufacturing route for your programme.

Yes. Marcus supports both fully custom components and OEM production requirements. We work with customer drawings, 3D CAD data, and technical specifications to plan tooling, casting, machining, finishing, and inspection. This helps buyers source parts that match application needs while also simplifying vendor management through a single manufacturing partner for multiple downstream operations.

Yes. Marcus provides in-house CNC machining to finish critical features after casting, including bores, threads, sealing faces, and mating surfaces. This is especially useful when cast geometry must be combined with tighter dimensional control on selected areas. Integrating machining with casting support can improve consistency, reduce logistics between suppliers, and shorten overall production timelines.

Marcus operates under IATF 16949:2016 and ISO 9001 certified quality systems. Depending on programme requirements, processes can include DFM review, APQP, PPAP, and FAIR documentation. Inspection and validation are built into production planning so customers receive parts with stronger traceability, controlled process discipline, and documentation suited to regulated or performance-critical industries.

Typical tooling lead times for investment castings are around 4 to 6 weeks. Actual timing depends on part complexity, tooling design requirements, approval cycles, and whether machining or finishing fixtures are also needed. Early DFM review can help reduce delays by identifying geometry, tolerance, or manufacturability issues before tooling is released for production.

Yes. Marcus offers in-house surface finishing and treatment support, including plating, anodising, powder coating, blasting, polishing, chromation, and heat treatment. These processes can improve corrosion resistance, wear performance, appearance, and assembly readiness. Keeping finishing close to casting and machining also helps maintain better control over quality, scheduling, and batch traceability.

Marcus supports customers in automotive, EV, aerospace, healthcare, electronics, energy, and industrial manufacturing. Investment casting is well suited to applications that need complex shapes, repeatable quality, and efficient material use. By combining casting with machining, finishing, and assembly support, we help OEMs and engineering teams source parts that fit broader production and performance goals.
