Grey iron and nodular iron castings Moulds and accessories, stands, beds of machine tools, tables, base plates, fixing plates, pressing tools, gearbox housings, flywheels, gears and chain wheels, pulleys, fittings, mandrels, elbows, weights, etc. Grey iron and nodular iron castings are made by uniform technological process of manual molding

into frames and to the ground (coffers) using forming mixture based on furan resins.

Steel castings Steel castings are made into CT mixtures based on sodium silicate and fenol-resol and usually they area heat-treated – normalization annealing, tempering or stress release annealing. Fluid motor boxes, pulleys, belt pulleys, grates and grate bars, chain wheels, gears and travel wheels, railway discs, slag ladles, funnels, castings for mining machines, rolls, etc.

Pattern equipment - Pattern Shop The Pattern Shop provides production of pattern equipment with dimensions up to 2 000 x 2 400x 4 500 and 3 000 mm made from wood, resin or plastics for the needs of the company´s foundry as well as for external customers. Workmanship of models in class H3, H2, H1 as per ČSN EN 12890.

In case of more demanding requirements of the customer we also cooperate with partnership pattern shops.

Castings are supplied according to the requirements of our customers • In the crude form • Heat-treated • Machined • With basic coating • Conserved • Free loaded (without packing) • On pallets or otherwise packed

Transport is ensured • By railway • By trucks • By special transport • By shipping

Material quality documents • Chemical analysis certificates • Mechanical properties certificates • Non-destructive testing – X-ray, US, magnetic method

Long term experience and know–how for production of demanding steel castings, grey iron and nodular iron castings for customers in the Czech Republic and abroad.
