In injection molding technology, hydraulic systems are an indispensable component of modern machines. They provide the power and precision required to make the plastic molding process efficient and reliable. The hydraulics ensure that injection molding machines work reliably even at high production rates and that complex parts can be manufactured precisely and in large quantities.
Hydraulic systems are crucial for the process of mold clamping in injection molding machines. The hydraulic cylinders close the mold under high pressure so that the molten plastic can be injected precisely. After injection, the hydraulics ensure that the mold remains securely closed until the material has cooled and solidified.
After cooling, the mold is reopened by hydraulic cylinders and the molded part is removed from the mold through a hydraulically operated ejector. This precise process must run seamlessly to avoid production interruptions.
Hydraulic systems play an important role in the pressure control in injection molding machines. The pressure must be maintained precisely throughout the entire spraying process in order to ensure consistently high-quality products.
Axial piston pumps and internal gear pumps deliver the required pressure for the spraying process. These pumps are designed for high efficiency and precision to ensure smooth operation of the machines.
These motors drive various components of the injection molding machines to ensure the precise movements required for the production of complex parts.
These linear actuators ensure that the mold securely closes and opens. Their precision is crucial in order to avoid errors in production and to produce consistently high-quality plastic parts.
Valves regulate the flow of the hydraulic fluid in order to control the movement of the cylinders and ejectors in the injection molding machine. They play an important role in controlling pressure and speed during the production cycle.
