At Marcus Hi-Tech Engineering, precision die casting is where excellence begins. We complement it with a full range of in-house secondary operations to deliver fully finished, ready-to-use components.

From precision machining and surface finishing to coating, painting, and assembly, every process is engineered to meet exact specifications and deliver superior performance in the end application.

CNC Machining

✓CNC machines — 3/4/5 axis VMCs, turn-mill, drill-tap, vertical milling centres
✓High accuracy machining for complex geometries and tight tolerance parts
✓Turnkey machining solutions for automotive, aerospace, and industrial applications

Surface Finishing & Treatments

A wide variety of surface finishing operations enhance the functionality, strength, and appearance of components:

✓Powder coating and wet painting — durable coating for protection and aesthetics
✓E-coat and chrome/Ni plating — corrosion and wear-resistant surface protection
✓Anodising — improved surface hardness and durability for aluminium parts
✓Shot / bead blasting and vibro polishing — smooth finishes, ready for assembly
✓Resin impregnation and chromation — leak resistance and corrosion properties
✓Heat treatment — improved mechanical strength and metallurgical properties

Assembly & Integration

Our semi-automated assembly lines deliver fully tested, ready-to-install mechanical and electro-mechanical assemblies, helping customers reduce supply chain complexity.

✓Mechanical assemblies and sub-assemblies for automotive and industrial applications
✓Electro-mechanical modules and plastic injection moulded assemblies
✓Integration of surface-treated and precision-machined components
✓On-time packaging, labelling, and fulfilment to customer standards

Quality Assurance in Secondary Operations

Every secondary process is governed by stringent QA/QC standards to ensure consistent quality and performance:

✓Inline inspection and sampling during production
✓Dimensional validation using CMMs and gauges
✓Leak testing for pressure-tight castings
✓Metallurgical and surface quality analysis
Why it matters

Why This Matters for Your Programme

What this capability changes for the engineers and buyers running the programme.

One Supplier

Casting through to finished, packed component.

Tight Tolerances

CMM-verified dimensional control on every batch.

Finish Range

Coating, plating, anodising, and polishing under one programme.

Reduced Logistics

Fewer hand-offs between vendors, fewer delays.

What secondary operations does Marcus provide after die casting?

Marcus offers a full spectrum of secondary operations to deliver finished, ready-to-use components. These include precision CNC machining, surface treatments (powder coating, anodising, plating, wet painting, e-coat), heat treatment, polishing, blasting, resin impregnation, and mechanical/electro-mechanical assembly.

How does CNC machining add value to the die casting process?

CNC machining brings as-cast features to final tolerance — critical bores, sealing faces, threads, and mating surfaces — so the component arrives ready to assemble rather than needing a separate machining supplier and an extra logistics leg.

Are secondary operations covered by the same quality system?

Yes. Secondary operations run under the same IATF 16949:2016 and ISO 9001 certified quality system as casting, with inline inspection, dimensional validation, and documented results.
