Low Pressure Casting Machine
The standard in low pressure casting machines from LPM.
The 4+4 column vertical press of the low pressure casting machine is placed above the holding furnace.
By
means of a mechanical scissor lift system, the furnace can be raised to 250 mm to reach
its working position below the dies mounted in the low pressure casting
machine.
The furnace is mounted on guide ways allowing it to
move horizontally and slide out frontally for ease of maintenance. On request,
a tilting feature can also be supplied to facilitate loading operations of
the molten aluminum metal material and easy cleaning at the end of the
casting process.
The electric holding refractory
furnace, with proportional pressurization control, is brought to working
temperature by three heating elements protected by APM tubes made of
sintered steel.
 Casting ejection is hydraulically operated and a rotary arm
catches the casting 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
is PLC managed with either a Siemens controller or Allen Bradley.
Dies placement to low pressure casting machine is quick and simple with full
frontal access to the machine.
The switch and control cabinet and hydraulic pack complete the assembly.
