Quartz sand production for foundry

We started producing coated sand in 1966 and became one of its largest producers in Europe. The sand is used to make cores and masks following the Croning process.

We produce coated sand for grey and nodular cast iron, aluminium, non-ferrous metals, and cast steel.

Packing: coated sand is filled in reusable metal containers (1m3), large bags (1 and 1.5t), and 25-kg paper bags.

Sieved casting sand is used to make moulds and cores following different procedures: Cold Box, Croning, Furan, and CO2

• Grain Size: 0,18 – 0,71 mm (MSP-50)

• Grain Size: 0,125 – 0,50 mm (MSP-30)

• Grain Size: 0,09 – 0,355 mm (MSP-22)

• Grain Sizee: 0,09 – 0,355 mm (MSP-20)

• Grain Size: 0,09 – 0,25 mm (MSP-18)

• Grain Size: 0,0 – 0,18 mm (MSP-15)

• Grain Size: 0,063 – 0,71 mm (MAP-1/S)

• Grain Size: 0,063 – 0,355 mm (MAP-5/S)

• Grain Size: 0,063 – 0,355 mm (MAP-5)

• Grain Size: 0,063 – 0,71 mm (MAP-1)

Refractory mass is acidic and based on quartz sand with 0.0–10.0mm large grains.

Clay content ranges from 45% to 50% and moisture content from 16% to 18%. Natural quartz clay is used for enclosing casting pots and cupola furnaces. It is refractory and plastic.

Packaging: in large 1500kg bags
