Insulating Riser Sleeves / Direct Pour Sleeves

At Rudransh Industries (P) Ltd we understand our customer needs and are constantly doing research to offer products to suit the changing needs of the foundries. The use of riser sleeves increases casting yield by allowing smaller riser sizes than conventional sand risers and reduces cleaning costs. The riser and casting contact area is significantly reduced, thereby eliminating the need for breaker cores. The reduction in contact area also allows risers to be located over a smaller area, enabling a reduction or elimina­tion of metal padding.

Benefits

  • Improved casting yield
  • Improved metal cleanliness
  • Reduced energy costs
  • Improved metallurgical properties
  • Reduced riser contact area
  • Reduced casting cleaning costs
  • Consistent Sleeve Shapes
