Sleeves

Exothermic and Insulating Feeder Sleeves for Iron and Steel Castings


Highly exothermic and insulating feeder sleeves are designed for use in iron and steel casting applications. These sleeves are engineered to deliver consistent and repeatable performance, validated through stringent quality control procedures at all stages of production. They promote uniform and directional solidification, resulting in improved casting yield and a reduction in riser metal requirements.

Product Range – Feeder Sleeves

The feeder sleeves are available in both Exothermic and Insulating configurations, in the following size ranges (in inches):



Exothermic Sleeves

The Exothermic sleeves are available in open, blind, oval and V-notch configurations, in the following size ranges (in inches):

  • Sesmin – Ex 160 (S)
    Size range: 1″ to 6″
    Type: Highly exothermic
  • Sesmin – Ex 150 (S)
    Size range: 7″ to 16″
    Type: Mildly exothermic Insulating Sleeves
  • Sesmin – In 130 (S)
    Size range: 2″ to 16″
    Type: Highly insulating


Insulating Sleeves

The Insulating sleeves are available in open, blind and V-notch configurations, in the following size ranges (in inches):

  • Sesmin – In 130 (S) (pictures
    Size range: 2″ to 16″
    Type: Highly insulating


Application Recommendations

  • Sesmin – Ex 160 (S) sleeves are highly exothermic and insulating feeder sleeves, recommended for all grades of iron and steel castings.
  • Sesmin – Ex 150 (S) sleeves are mildly exothermic and insulating feeder sleeves, suitable for all iron and steel casting applications.
  • Sesmin – In 130 (S) sleeves are highly insulating feeder sleeves, specifically recommended for steel and alloy steel castings

Technical Benefits

  • Significantly improves casting yield
  • Reduces fettling and finishing costs
  • Enhances overall foundry productivity
