The basic operation involved two halves of a mold, mounted on supporting platens, being clamped together at high pressure using hydraulic cylinders. Plastic substrate pellets were melted in a special screw device and the liquid injected under pressure into the mold cavity as fast as possible.

These types of machines employ hydraulic cylinders to clamp together two halves of a mold at high pressure. Plastic substrate pellets are then melted, and the liquid is injected into the mold cavity. Once the plastic has cooled and hardened, the mold halves are separated, the part is extracted, and the process is repeated.

When pump pressure has been build up in the cylinder, the MP-intensifier will automatically increase the pressure as required. This setup is also used in the reverse setup, where high pressure is required to initiate the movement of a cylinder, e.g. in core pulling in a plastic injection molding machine.

Here, the equipment cost is relatively high but the main attraction is the amenability of the injection-moulding process to a high production rate. In injection molding, a definite quantity of molten thermoplastic material is injected under pressure into a relatively cold mold where it solidifies to the shape of the mould.

The dual control moves actuators quickly into position to minimize machine cycle times, then provides pressure control to ensure tight process control. Die casting and injection molding machines place some hefty demands on hydraulic systems. They must operate with high repeatability to ensure high product consistency and low scrap rate.
