Sand preparation

Vulcanus Castings makes huge demands on the casting sand. The casting sand largely determines the quality of the casting in terms of dimensional accuracy, surface quality and formability. Vulcanus Castings works with a closed green sand system, which prepares 100 tonnes of casting sand per hour. The casting sand is upgraded to the desired properties with each round. This process is fully automated, with each mixer being adjusted. Due to its complexity, the process is continuously monitored, data is analysed weekly, and an extensive sand sample is carried out every month in order to maintain optimum sand quality.

Casting

The moulds at Vulcanus Castings are made using an air impulse casting machine. This means the moulds are compressed with an air impulse. This is an automated process with a capacity of 100 moulds per hour. The moulding box size in this casting line is 1000*800*300/300.

Core maker

The core determines the cavity in the casting. Vulcanus Castings has a core factory with various cold-box core shooting machines, up to 40 litres. Vulcanus Castings has plenty of knowledge and experience in the field of making cores, which means they are able to produce very complex cores by using various types of sand and additives, and by formulating core packages. In addition, the cores are coated to achieve a high-quality surface finish.

Foundry

After the moulds have their cores, the moulding boxes are automatically closed and prepared for casting. Vulcanus Castings has a fully automatic casting machine. The casting machine has a buffer of 10 tonnes of liquid iron, which is replenished by transport pans from the smelter. The temperature of the liquid iron in the casting machine is continuously measured and can be adjusted where necessary with induction heating. A thermal and spectral assessment of the iron is carried out every half hour. The quality of the liquid iron is therefore 100% guaranteed.

Finishing

The poured moulds will cool for about two hours on the cooling track, after which the products are shaken out of the sand mould, blasted clean and deburred. The products are then assessed by skilled personnel for their visual, mechanical and metallurgical properties. Finally, the Vulcanus Castings paint shop offers the application of a coat/lacquer to the casting at the desired specifications.
