Features & benefits
Main benefits of using FEEDEX sleeves:
- Very high yields
- Highly exothermic
- High strength
- Suitable for spot application
- Low fettling costs
High exothermic spot feeder sleeves
FEEDEX high strength exothermic sleeves for iron castings
The primary use of FEEDEX sleeves is on modern high-pressure automatic greensand moulding lines which place extra demands on ram-up feeder sleeves.
These products must be able to withstand the highest moulding pressures, yet be simple and convenient to apply. FEEDEX sleeves provide the highest compressive strength resistance and can be applied easily using a wide range of application technologies.
FEEDEX K sleeves are fitted with a patented collapsible metal core, which allows precise spot feeding on the smallest casting section. In addition, the core is designed to ensure an optimum feeder knock-off after casting. FEEDEX K sleeves can be applied on horizontal and vertical high pressure moulding lines.
The self-centring FEEDEX VAK feeder sleeves are designed for ram-up applications in greensand moulding lines. In combination with the appropriate support pin, the FEEDEX VAK sleeves can be easily applied on fast cycling automatic moulding lines. The new FEEDEX VAK generation is also produced with the proven FEEDEX HD formulation, a low fluoride containing, high exothermic and high strength feeder material. The VAK /61 series is designed for moulding machines with standard moulding pressure and the VAK /62 series for extreme moulding pressures.
FEEDEX HD V feeders are thick walled highly exothermic sleeves. The small feeder volume and small riser-to-casting contact area make them especially suitable for use on casting sections with a limited sleeve application area. FEEDEX V feeder sleeves can be used in both mass iron and jobbing applications.
FEEDEX HD VS is a range of self-centering feeders, which can be applied quickly and safely to automatic moulding lines. They can be used with specially designed spring pins and locating cores, to enable spot feeding of even the smallest contact area.
FEEDEX FEF is a unique fluoride emission free, low VOC highly exothermic, high strength feeder sleeve material, ideal for high pressure casting, to support greensand foundries committed to reducing environmental impact and costs as their need for high performance spot feeders continues to step up.
