SHELL-MOLD CASTING FOR CAST IRON AND STEEL
The process of casting into shell molds is similar to casting in sandy-argillaceous forms. The molten metal is poured into a disposable thin-walled shell made by applying a mixture of sand and resin to the model of the desired product.
The model is reusable and is used to form several shell shapes.
Reusable templates allow you to increase production rates, while disposable templates allow you to obtain geometrically more complex and accurate products.
For casting into shell molds, we use both ferrous and non-ferrous metals, most often carbon steel, cast iron, alloyed and stainless steels, aluminum and copper alloys.
Minimum possible weight of the part:: 0,1 kg Maximum possible weight of the part: 20 kg Minimum possible sizes of the part: Depending on the structure Maximum possible sizes of the part: 1000mm, depending on the structure Minimum possible wall thickness: 5 mm Maximum possible wall thickness: No limitations Tolerance class for casting: Casting tolerance ST8 ISO 8062 Minimum possible batch: 1000 kg
Standard materials used for shell-mold casting
Grey cast iron Ductile cast iron High carbon steel Low carbon steel Carbon steel Stainless steel
Application of produced parts
- Agricultural parts
- Railway parts
- Pump housings
- Parts for oil and gas industry
- Parts for mining industry
The most common products produced by this type of casting are medium-sized high-precision products, for example, gears, housings, cylinder heads, connecting rods, levers, etc.
