Zetwerk uses industry-leading die casting methods like High Pressure Die Casting (HPDC), Low Pressure Die Casting (LPDC) and Gravity Die Casting (GDC), with capacity ranging from 80T to 3500T. Shaped in a variety of metal alloys like aluminum, zinc, copper, brass and bronze alloys, die cast components are formed in precision steel tools, moulds and dies as per volume, size, weight, geometry, complexity and surface finish requirements.
To smoothen the parting line and remove gates, overflows and flash, die-cast components are vibrated and tumbled. Thermal deburring is used to remove burrs and other imperfections from die cast parts.
Secondary Operations and Machining
Die-casting components are drilled, tapped, reamed and post-processed by precision CNC machining to meet design criteria and dimensional tolerances required for performance and quality.
Further finishes are added to die-cast components to remove impurities, improve wear resistance and durability and add surface texture through shot blasting.
Plating and Painting
Zetwerk offers combined conversion coatings and functional finishes to die castings to serve as base coating under paint or as final surface finish. Aluminum die casting includes anodized black, anodized clear, anodized clear hard coat, and chromate (Zinc die castings only). Cosmetic finishes are often painted through powder coating or liquid painting for fine, medium and coarse surface finishes.
Quality Control and Assembly
Zetwerk’s Quality Control includes testing and heat treatment of cast components. Salt Spray tests and Hydrostatic and Pneumatic pressure tests determine the corrosion resistance of the die casting. For ease of assembly, Zetwerk also offers the produced parts in a sub-assembly along with hardware and other components necessary for assembly.
