Raw materials for forged rolls, raw material for shear blades and shearing knives

The most important aspect of tool making is selection of right material from right source. The main parameters which have to be ascertained in the raw material are –

  • Composition
  • Segregation
  • inclusion level
  • Grain size
  • Carbide distribution
  • Degree of spherodisation.

Following inspection are carried out for all different size of bars of same heat
     

  •     PHYSICAL INSPECTION AND SURFACE DEFECTS
  •     CHEMICAL COMPOSITION
  •     MICRO STRUCTURE
  •     MACRO STRUCTURE
  •     HARDEN ABILITY
  •     ULTRASONIC TESTING

      
Approx 90% of our raw material are bought directly from the manufacturers. we avoid raw material procurement from Stockists/ Traders to achieve maximum cost control and quality.
