AFCIFEED 51

• AFCIFEED 11 is Insulating compound whereas AFCIFEED 21/ 61 are so designed that they are exothermic as well as insulating in their net effect & AFCIFEED 31/ 41/ 51 is a special range of highly Exothermic compound. The initial exothermic reaction results in increment of heat to some extent that prolongs the solidification period of liquid metal thereby creating pressure at the top of the riser. In their second stage it acts as an insulating barrier for a long time thus increases the feeding performance of the riser. The efficient metal feeding consequently results in higher yields leading to high metal saving ,Instruction for use of AFCIFEED 11/ 21/ 51
• Place a quantity of AFCIFEED 11/ 21/ 51 on the top of the riser so as to provide a cover of 25-30mm depth.
• Allow the exothermic-insulating reaction to proceed.
• Top up with more metal if necessary.
• In case of Heavy castings if necessary top the riser again with AFCIFEED 11/ 21/ 51.

Instruction for use of AFCIFEED 31/ 41/ 61 :

• AFCIFEED 31/ 41 is a range of MOULDABLE EXOTHERMIC compound available in POWDER form that can be moulded to the shape as per requirement.
• AFCIFEED 61 is an Exothermic cum Insulating compound available in Square shape in different sizes as per suitability.

According to riser peg design, AFCIFEED 31 / 41 / 61 of proper dimension should be mounted on riser prior to moulding. For optimum riser performance hot feeding and anti-piping compound such as AFCIFEED 11 and AFCIFEED 21 must be used. When the molten metal reaches to riser height in the mould, the exothermic reaction starts on contact with the sleeves. The exothermic reaction results in increment of heat to some extent and also acts as an insulating barrier for a long time thus increases the feeding performance of the riser. The efficient metal feeding consequently results in higher yields leading to high metal saving.

Consistent Advantages:

• Productions of sound castings free from defects.
• Useful particularly where box parts or casting design makes risering difficult.
• Increase in feeding efficiency and yield, through minimum heat loss and heat dissipation
• Reduction in riser sizes improves the foundry yield through metal saving, higher product output per mould due to higher saving in riser metal, savings in high value metallic inputs, drastic reduction in fettling costs.
• Because of better feeding the rejection due to shrinkage defects are reduced.
• Use AFCIHOLD an excellent Slag holding compound that ensures clean metal surface free from Slag by coagulating the impurities & also imparts an insulating effect.

• AFCIFEED should be kept in tightly closed box/ bag in a cool and dry place to prevent it from moisture contact and avoid external contamination.
• AFCIFEED 11/ 21/ 31/ 41/ 61 are exothermic-insulating compound and AFCIFEED 51 is highly exothermic compound, hence should be kept away from flame or from other ignition source.
• Coating and torching of AFCIFEED 31/ 41/ 61 should be avoided inside the mould.
• Damage and displacement of AFCIFEED 31/ 41/ 61 should be prevented while making moulds.

• AFCIFEED 11/ 21/ 31/ 41/ 51 is available in 50 Kgs. BAGS.
• AFCIFEED 61 is available in Corrugated Boxes.
