Foundry

Rastgar Engineering has been producing high quality castings for the automotive sector since 50 years. We specialise in ductile and grey iron castings, ranging from 2Kg - 45Kg. Our proficient foundry team produces finest castings through 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 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
