Wax Runner Extruder

WREX1989-008

In lost wax casting process, the injected wax patterns have to attach on wax runner to make a cluster, that wax runners are produced by the wax runner extruder.

In the steps of lost wax casting process, the wax patterns have to be coated with ceramic materials, but due to small sizes it is hard coat each separately so the best way is to make a tree of the similar parts, which required runners to attach the wax part on it. The wax runner extruder uses to develop runner in different sizes from 10 mm round / square shaped to 100 mm round / square / triangle shaped, in different length as per requirement. It is provided with 2 heat zone, one at wax tube and second at extrusion port, the hydraulic cylinder can produce 15 tons of pressure to extrude runners in continuity, the wax tube of 125 diameter can hold 2 wax billets at a time, hyd. system provided with sufficient pressure and flow control ensures high pressure. Eclectic control panel and foot padel controls the heat zones and revers forward operations, equipped with best make switch gears and wires, also ensure machine and company wiring safety

It operates manually, by paling round shaped wax billets in wax tube and closing the safety gate, the machine come in to position of extrude. By pressing forward foot switch hydraulic cylinder moves forward with pre set presser and flow, due o heater temperature wax billet takes form of die shape and start extruding until whole wax finish off, the long runners need to cut with any sharp knife in to required length. The hyd. Cylinder returns back to the reset position and the cycle repeats for more extrusion.
