Precision Investment Casting Services Lost Wax

Precision investment casting, also called lost wax casting, creates detailed metal parts by forming a ceramic shell around a wax pattern, then melting the wax out before pouring metal. The process is ideal for complex geometries, fine surface detail, and components that need tighter dimensional control than many conventional casting methods can provide.

Marcus supports investment castings in carbon steel, duplex steel, copper alloys, and super alloys through its certified partner network. This material range makes the process suitable for demanding applications in aerospace, industrial manufacturing, energy, automotive, and healthcare, especially where strength, corrosion resistance, or temperature performance are important.

Marcus can support investment cast parts up to 120 kg. This allows the process to cover a wide range of precision components, from smaller intricate parts to larger engineered castings. During project review, the team evaluates geometry, wall thickness, alloy selection, and downstream machining needs to confirm the best manufacturing route.

Yes. Marcus provides in-house CNC machining with more than 20 machining centres, including 3, 4, and 5 axis capability. This allows cast parts to be finished with tight tolerances on critical features such as bores, threads, sealing faces, and mating surfaces, reducing the need for multiple suppliers and improving dimensional consistency.

Marcus operates under IATF 16949:2016 and ISO 9001 certified quality systems. Depending on the program, support can include DFM review, APQP, PPAP, FAIR, inline inspection, and advanced metrology. This structured approach helps customers maintain traceability, validate production readiness, and reduce quality risk across prototype and serial production stages.

Yes. Marcus supports tooling through its dedicated Tool Room and structured new product development process. Services include CAD/CAM integration, simulation, DFM review, rapid prototyping, T0 and T1 trials, and engineering change management. This helps customers refine part design early and improve manufacturability before committing to full-scale production.

Marcus supports customers in aerospace, automotive, EV, electronics, healthcare, energy, and industrial manufacturing. Investment casting is especially useful in these sectors because it can produce complex shapes with repeatable quality, while also supporting secondary machining, finishing, and validation requirements often needed for regulated or performance-critical applications.

Yes. Marcus serves customers across India, the United Kingdom, North America, Australia, Italy, Mexico, Vietnam, and the Middle East Asia region. With headquarters in Coimbatore and a broader manufacturing partner network across India, Vietnam, and China, the company is structured to support global sourcing programs with coordinated quality and supply management.
