Applications : Runner bars and down sprues of different sizes and shapes are required for clustering of the wax patterns to form ‘trees’. Gravity casting is a preferred method to produce these in large numbers to support production. The ‘Sprue Maker’ is designed for gravity casting of runner bars and sprues – with or without metallic inserts. A sprue maker consists of a Wax melting chamber, Wax reservoir, Pneumatic Piston Pump, Set of sprue dies and Cooling water chamber.Melting Chamber :- The melting chamber is a wax melting device that can hold about 30Kgs of solid wax. Wax is continuously melted and flows into the wax reservoir where it is stirred continuously at a constant temperature to feed the piston pump on demand. The chamber is located at the top of the wax reservoir. Electrical strip heaters quickly heat up the Aluminium base to provide a melting rate of about 15Kgs/hr. Wax slabs are stacked in the melting chamber. Piston Pump :-The machine is provided with a temperature controlled pneumatic actuated piston pump. The pump can provide a max. discharge of 3 lpm. The molten wax is discharged from the pump outlet through a heated pipe. The delivery of the pump fills the carriage mounted dies by gravity. Dies Set :- Two sets of dies designed to carry an Aluminium metal insert for use with a Ceramic pouring cup and Plastic coated handle is supplied along with the machine as part of standard supply. Sprue moulds of client specific design can also be supplied instead on demand.Die cooling :-The dies are mounted on a rotary carriage for movement from wax filling point to immersion into cooling water chamber to stripping station. This enables quick movement and high productivity.
