Description

OEM Cast Iron Products

Sand casting process offers the greatest flexibility and the most cost-effective tooling. Our sand casting foundry is equipped with a complete metallurgical laboratory to determine the chemical and mechanical characteristics of each melt and to analyse the metallugic condition of the molten metal before pouring. Microsections are examined under the microscope to obtain final information on the solified casting. We issue 3.1 certificate for each delivered part on customer request.
