Faprosid High Denity MT Feeder Sleeves John Winter

Highly Exothermic Feeder

MT / MTV High Density

For Iron & Steel Castings

MT High Density Feeders offers:

  • Yield improvement means reduced energy costs. 

  • Smaller contact area on the casting means ease of knock off and reduced dressing times. 

  • High density feeders can be placed directly on an area to target shrinkage.

  • Smaller feeders can sometimes increase the number of castings on a pattern plate.
