S. S. KHARDEKAR INDIA PVT. LTD.
1) Filtration:
The Filtration effect is due to the mechanical entrapment of inclusions. The change in flow & pressure through the filter causes the contaminants (Inclusions) to stick to the filter labyrinth (Web of pore).
VUKOPOR Filter has maximum open pore structure (minimum internal blockages). This enhances the filtration efficiency & flow rate. It also reduces entrapment of air bubbles into the metal downstream. It changes Turbulent flow to a Laminar flow. It also reduces the oxide formation within the filter.
2) Feeding :
Once Filtration takes place Ceramic Foam Filter floats at top & Feeding action starts. Feeding effect is due to nature of both highly Insulating & high refractoriness 1400-1500OC of the Sleeve. It improves the temperature gradients within the castings & promotes the Directional Solidification.
1. Conventional ACEFEED-DP :-It can be used as Ram up or insert applications. It is suitable for Jolt squeeze molding machine, hand molding & for High Pressure & Disamatic Molding machine.
2. Insert types ACEFEED-DP :-In this type of ACEFEED-DP, ceramic foam filter is placed into the seat provided at the top of the sleeve. It can be usedin insert applications in the pre-formed Mould cavity in the upturned molding system. The sleeve is located below the down-sprue. It is available in 50, 70 & 90 dia.
3. Neck down type ACEFEED-DP :-It is mainly used for top feeder application where feed metal requirement is higher. It is directly placed on the casting surface with or without breaker core.
