SAND CASTING

Zetwerk’s sand casting services are a cost-efficient method for producing small and large parts from various ferrous and non-ferrous alloys. The process is calibrated to produce large scale workpieces in high volumes and for short run work.

SAND CASTING

METHODS

Zetwerk utilizes green-sand, no-bake, CO2 and shell molding techniques to produce complex parts from grey iron, ductile iron, carbon steel, alloy steel, and stainless steel grades as well as from non-ferrous metals, such as aluminum, brass, bronze and copper.

CASTING CORES AND PATTERNS

Zetwerk’s core-making capabilities cater to all shapes, sizes and configurations. Production shell core boxes (cast iron or aluminum) and CO2 cores are used for developing prototypes. To create new patterns, new core tooling and mold patterns are designed from customer drawings and made precise and accurate through CNC machining. Existing shell core tooling and mold patterns are transferred and adapted for production

FINISHING TOUCHES

Proof machine and finish machine are used to smoothen the rough surface of sand cast parts, improve profile and tighten dimensional tolerance. Heat treatment is applied to achieve the desired mechanical properties as well as the requisite surface treatment. Zetwerk also offers assembly services in which the produced parts are put together in a sub-assembly along with hardware and other components necessary for assembly.

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.
