BPB Low Pressure Casting Machine for Aluminum:

The simplest low pressure casting system for routine operations.

Built in accordance with the basic concepts of ergonomics, this low pressure die casting machine features a 4+4 column vertical press and an electric holding furnace with proportional pressurization control.

 Working temperature is obtained by three heating elements protected by APM tubes made of sintered steel.

Casting ejection is hydraulically operated and a rotary arm catches the piece and removes it from the press swivelling outwards, thus guaranteeing maximum safety for the operator.

 

Thermal control of the mold is achieved through a system of 8 separate circuits (air, water, or a mix) and PLC managed.

The switch and control cabinet and hydraulic pack complete the assembly.

The furnace is raised off the floor and mounted on guideways to allowing it to travel to the back of the machine in three different positions (3-motion reverse) for easier mold changing and to facilitate replacing riser tubes directly from the operator platform (Fastube ).
