FEEDEX*HD Highly exothermic and high strength feeder sleeve for iron and steel castings. General Description
FEEDEX HD is a high compressive strength sleeve. Ideally suited for high pressure & automatic greensand moulding lines for ram-up applications. The novel design of these reverse taper feeder sleeves has been developed with the aid of advanced simulation techniques. The thicker wall section in the upper (cap) part of the sleeve produces an optimum superheat of the feeder metal furthest away from the casting. The thinner wall section toward the base of the sleeve is so designed to compensate for the thermal potential of the casting. The chamfer on the cap of the sleeve reduces the mechanical impact on the unit during moulding, but has negligible influence upon the thermal modulus of the sleeve.
Application
FEEDEX HD sleeves are highly exothermic with MEF about 2, suitable for the production of all types of high quality iron castings. Novel design of FEEDEX HD and breaker core, gives excellent feeding performance & knock off. FEEDEX HD feeder sleeves are well proven and established, which are used to feed all types of iron and steel castings in the modulus range between 0.6cm & 3.4cm. While selecting the sleeve size, care should be taken to ensure that casting modulus, its feed metal requirement and feeding distance criteria are satisfied.
Benefits
Very high yield High strength Small foot print Suitable for spot application Low fettling costs

Product Description
FEEDEX HD VS Sleeves - Self-centering sleeves FEEDEX HD VS Sleeves are a range of self-centering feeders, which can be applied quickly and safely to High pressure moulding lines and especially in self set moulding processes.
FEEDEX HD VS Sleeve
With Standard Breaker core
With locating pin
Application
FEEDEX HD VS Sleeves can be used with specially designed breaker core with locating pin, to enable spot feeding of even the smallest contact area. In the case of high feed metal recovery from VS feeders, the reduced modulus of the residual feeder must be taken into account.
Benefits
FEEDEX HD VS sleeves with breaker cores are self-centering feeder types. Along with appropriate locating pins, application of these sleeves with breaker cores is relatively easy for patterns on a highproduction moulding line.

Precaution
Exothermic feeders can in some cases, depending upon the degree of feed metal requirement and alloy chemistry, cause a change in primary graphite structure adjacent to the feeder. The graphite structure should always be checked to ensure correct microstructure.
Packaging
FEEDEX HD feeder sleeves are available in shrink wrapped cardboard trays. Shrink wrapped packing is done for the ease of handling and for reducing moisture pick-up in sleeves.
Storage & Shelf Life
The sleeves must be stored under dry conditions. Shelf-life is 1 year, however it is recommended to use the sleeves within 3 months.
Health & Safety
See Safety Data Sheet, copies of which are available on request.
