One of the MOST ENERGY EFFICIENT designs available amongst Injection Moulding Machines incorporating Efficient and sound reduced hydraulic pump. It is consistent with Pratishna Engineer's Position as being the No.1 in Energy efficient Injection Moulding Machine technology amongst all hydraulics type machines available to customers. The advanced INJECTION UNIT make its way better then others.
The person designing the mold chooses whether the mold uses a cold runner system or a hot runner system to carry the plastic and fillers from the injection unit to the cavities. A cold runner is a simple channel carved into the mold. The plastic that fills the cold runner cools as the part cools and is then ejected with the part as a sprue. A hot runner system is more complicated, often using cartridge heaters to keep the plastic in the runners hot as the part cools. After the part is ejected, the plastic remaining in a hot runner is injected into the next part.Injection Moulding Machine Price
