Foundry

Rastgar Engineering has been producing high-quality castings and wheel hubs for the automotive sector since 50 years. We specialize in ductile and grey iron castings, ranging from 2Kg - 45Kg. Our proficient foundry team produces the finest castings through the latest molding and casting machinery. Our skilled staff, foundry expertise, and years of industry experience enable us to provide world-class iron castings to our valuable customers.
Equipped with high-pressure moulding lines and induction melting, we have a capacity of 9,000 tons/year. We are competent to produce patterns and prototypes as per the customer’s requirements. We have established quality systems at every step to ensure defect-free castings. Other facilities include:

  • High Pressure Moulding Line from Heinrich Wagner Sinto (HWS)
  • Eirich Sand System                                          
  • Metal Treatment by Sandwich Process                             
  • Metallurgical Quality Control
  • Core Shop (Fordath, Roperwerk, Vogel & Schemmann)
  • Ultrasonic flaw detection
  • Impact testing at -30°C
  • Chemical and Mechanical Testing
  • Shot-blast and Tumb-blast Machines
