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.

Open Top Insulating Sleeves
Bimex 200
For Aluminium Castings
Bimex 200 insulating sleeves are specifically for aluminium sand castings. They are a 'body soluble' insulating material and provide good insulation and feeder properties. Available from 1 inch to 12 inch
Open Top Insulating Sleeves
Bimex 230
For Iron & Copper Alloys
Bimex 230 Insulating sleeves can be used for a wide range of non ferrous from aluminium through to copper alloys and even cast iron. Made from 'body soluble' material with good wall strength they are ideal for all round use for a foundry making multiple alloys and wants to buy just one grade of sleeve.
Open Top Insulating Sleeves
Bimex 400
For Iron & Steel Castings
Bimex 400 Sleeves are for higher temperature metals like iron and steel. They have strong wall strength and excellent insulating properties to feed the casting and help prevent shrinkage porosity in castings. Available from 1 inch to 24 inch dia.
Open Top Insulating Sleeves
Bimex 400 Domes
For Iron & Steel Castings
Bimex 400 Dome Sleeves are for higher temperature metals like iron and steel. They have strong wall strength and excellent insulating properties to feed the casting and help prevent shrinkage porosity in castings. Available with and without breaker core.
Open Top Insulating Sleeves
Bimex 820
For Magnesium Castings
Bimex 820 are insulating sleeves containing an inhibitor specifically for foundries casting magnesium alloys. Available in a range of sizes. Contact for more info.
Open Top Exothermic Sleeves
Bimex 369
For Iron & Steel Castings
Bimex 369's are an exothermic sleeve for iron and steel castings where maximum feed characteristics are essential. Available in a wide range of sizes.

A Range of Exothermic Powders to Boost Feeder Temperatures
Tested thoroughly for performance
Select from a range of highly exothermic and insulating grades
Low Fume grades for improved atmospheric conditions.
ALUMINIUM AND COPPER ALLOYS
Highly Exothermic Topping Compound
Exofeed AL412
Fast Firing
Exofeed AL412 is a fast firing highly exothermic topping powder for non ferrous small feeders
Highly Exothermic Topping Compound
Exofeed AL413
Fast Firing & Insulating
Exofeed AL413 is a medium exothermic topping powder with excellent insulating properties.
Exothermic Topping Compound
Exofeed AL414
Fast Firing & Insulating
Exofeed AL414 is a lower fume, exothermic topping powder for large feeders but has long lasting insulating properties.
IRON AND STEEL
Highly Exothermic Topping Compound
Ecofeed Fe431
Fast Firing
Fe431 is a fast firing, very exothermic topping powder for smaller feeders (1 inch to 4 inch). Its produces slightly more fume that the other 2 grades but benefits from very hot temperatures.
LOW Fume Topping Compound
Ecofeed Fe433
