High pressure die dasting
HPDC (High Pressure Die Casting) is a process of injecting a portion of liquid material, with a high speed and pressure into a mould made by hardened steel - to manufacutre a component with given dimensions and tolerances. Depending on the dimensions of components and number of cavities in the mould, there can be hundreds and even thousands of parts manufactured over an hour.
Since the dimensions of castings do vary - after all, produced are parts for watches and small instruments, weighing few grams up to the car structural components, or parts of car engines and transmissions, the dimensions of equipment for pressure casting vary as well.
Casting machine ready for casting consists of three parts:
1. CLAMPING MECHANISM
It is usually a horizontal press cantilever, which holds the moulds halves together, defying the considerable strength of injected metal.

2. DIECASTING MOULD (TOOL)
consisting of at least two parts (movabme and fixed), with a forming part of the shape of casting element, which can be equipped with sliding cores to produce more complex shapes.
The form is temperature stabilized (cooled and heated) and equipped with a mechanism to eject the finished casting.

3. INJECTION UNIT
it is a system that consists of a casting furnace, the injection chamber immersed in the liquid metal with the piston working in it (hot-chamber technology), or a piston chamber which is fed with molten metal injected into the mould.
ADDITIONAL EQUIPMENT
Casting machines are often equipped with auxiliary equipment such as automatic vats, automatic spraying unit (tool lubrication), robotic pickup arms. Castings can be cooled with air or water before being press-cut (trimmed) to remove the filler/inlet channel and vent system. All equipment associated with the machine is synchronized and controlled, to ensure a highly mechanized, automated and rapid manufacturing process with low commitment of the human workforce.
