Top quality

Steel casting solutions

We manufacture top quality carbon and alloyed steel products using three different casting processes:

Chemical Sand Casting

Our chemical sand moulding line, which offers greater stability, is the perfect choice for top quality castings in highly demanding markets

Investment Casting

When accuracy is needed, our lost wax line can ensure the repeatability, dimensional accuracy and correctness of the parts throughout the project
