KALMINEX 2000 are accurately formed, highly exothermic and insulating shapes suitable for feeding all grades of cast iron and steel. They are available as open or blind sleeves in the diameter range of 35 – 120 mm and can be used in both side feeder and top feeder applications. Developed for ease of application to highspeed, automated greensand moulding systems using the “insert” technique, the sleeves are applied to a cavity, pre-formed in the cope mould by a specially designed pattern. This allows an accurate fit of the sleeve into the cavity. KALMINEX 2000 sleeves can also be easily used for ram-up applications.

Although primarily designed for use on repetition castings, KALMINEX 2000 are also used extensively for jobbing foundry applications. The sleeve material has a density of 0.6 g/cm³ and therefore has good insulating properties. In addition, the liquid metal is heated by an exothermic reaction.

They are positioned on the pattern and rammed-up in situ. Suitable vents to facilitate mould gas removal on casting can be drilled through to atmosphere.

KALMINEX 2000 sleeves are frequently applied in combination with breaker cores. A wide variety of breaker core shapes, apertures and materials have been developed to suit the needs of individual foundry applications.

In vertically parted processes, KALMINEX 2000 and KALMIN S sleeves are placed in a specially designed cavity and can be used for top riser or side riser application. For horizontally parted shell moulds a suitable cavity is formed in the invested shell mould. Conventional breaker cores can also be used for top riser applications to improve knock-off.

		the exothermic reaction and high insulation factor ensure that feeder volumes are minimised, substantially improving yield
		fettling costs are substantially reduced, especially where breaker cores are used
		isolated sections can be adequately fed, reducing the need for expensive padding
