Our mechanical work-shop provides full cutting of aluminium casts and other materials (brass, steel, plactic and others).
History of our company
Tradition of Kovolit Česká dates back to 1936 when we started with building and production of drink fittings and bell-casting. Bell-casting had been done by Mr Manousek by 1953. Afer that this production was moved to Zbraslav. The production of drink fittings was finished in 1990.
Present situation
Nowadays Kovolit Česká specializes in production of aluminium sandcasting and moulds. Our 50 years´ experience in this field represents profound knowledge that can be seen in quality and accuracy of our deliveries. Total annual production is roughly 900tons of Al moulds per year. The main customers are engineering, textile and construction companies. The weight of aluminium casts are from 0.10kg 400kg. Our foundry offers models, moulds, cores and a process of sand drying. Due to customers´ wishes we also provide heat treatment, hardening, x-ray of aluminium moulds and testing of mechanical qualities of materials. A mechanical work-shop, that provides cast machining, milling, turning, grinding, drilling, varnishing and production of mechanical parts from all kinds of materials (Al, Ms, steel, stainless steel, plactic and others), is a part of our company. Kovolit Česká employs about 130 workers.
