Aluminum CNC Machining & Die Casting Services

Marcus offers cold chamber die casting and low pressure die casting for aluminum components. Cold chamber die casting is suited to high-pressure production of structural and industrial parts, while low pressure die casting is ideal for dense, heat-treatable components with reduced porosity. The team also supports tooling, machining, finishing, and validation as part of a complete manufacturing solution.

Marcus supports a wide range of aluminum alloys depending on the process and application. For die casting, compatible alloys include ADC10, ADC12, A380, A384, AlSi10MnMg, LM2, LM6, LM24, and LM25. For low pressure structural applications, A356 and A357 are preferred. Alloy selection is guided by strength, finish, machinability, and end-use requirements.

Marcus performs precision CNC machining on aluminum components using in-house 3, 4, and 5-axis equipment. Critical mating faces, bearing bores, threaded interfaces, and sealing surfaces can be machined to tolerances of ±0.005mm. Custom jigs and datum-based fixturing are used to maintain positional accuracy and repeatability across production runs.

Yes. Marcus provides integrated die casting and CNC machining support, which helps reduce supplier handoffs and improve process control. Customers can source cast aluminum parts, precision machining, tooling, finishing, inspection, and even assembly through one partner. This single-source model helps shorten lead times, simplify coordination, and improve consistency from prototype through production.

Yes. Marcus supports early-stage development as well as repeat production. The company offers DFM review, simulation, rapid prototyping, T0 and T1 trials, and validation before scale-up. Once approved, programs can move into medium or high-volume manufacturing using in-house casting, machining, finishing, and quality systems designed for repeatable output.

Marcus offers in-house surface finishing and treatment options including anodising, powder coating, wet painting, chrome and nickel electroplating, cathodic e-coat, blasting, polishing, chromation, resin impregnation, and heat treatment. Parts are pre-treated before finishing, and testing can include ASTM B117 salt spray, XRF coating thickness, and adhesion cross-hatch checks with batch certificates.

Marcus operates under IATF 16949:2016 and ISO 9001 certified processes. Quality planning and validation can include DFM, APQP, PPAP, FAIR, in-line inspection, and advanced metrology such as CMM. Depending on the program, the team also uses OES, leak testing systems, and air plug gauges to verify dimensional accuracy, material integrity, and functional performance.

Marcus supports customers in automotive, EV, aerospace, electronics, healthcare, energy, and industrial manufacturing. These sectors often require lightweight, durable aluminum components with tight tolerances and reliable finishing. The company’s combination of casting, machining, tooling, and quality control makes it suitable for both cosmetic and structural applications across demanding production environments.
