Production engineering

We guarantee professional support and consultancy by highly qualified personnel with many years of experience in design of castings and model equipment.


Castings are shaped and manufactured in a manual forming shop using self-hardening mixtures based on furan resin, the quality of forming mixture is tested and evaluated in our own sand laboratory.

Surface treatment

We paint castings in sealed boxes, mostly using two-component and special paints. Viscosity and composition of paints is regularly monitored. We check the thickness of applied layer with special meters.


We provide heat treatment and machining of castings in the modern heavy mechanics operation at our parent company TOS VARNSDORF a.s.
