In recent years, hydraulic injection molding machines have become increasingly popular. They offer a number of benefits such as:
- Greater clamping force - Hydraulic machines can provide greater clamping force than electric machines, making them suitable for the production of parts of different sizes and thick-walled products.
- Ease of Maintenance - Hydraulic systems are more familiar to many operators and technicians, which can make maintenance and repair easier.
- Reliability and Durability - Hydraulic machines typically handle heavy and long-lasting loads well, making them reliable in intensive production environments.
- Versatility - hydraulic machines can be more flexible in terms of adaptation to different types of forms and production processes.
What are the features of the device and operating principles of a hydraulic injection molding machine? What are its advantages and industrial applications?
Design and operation of a hydraulic injection molding machine
Hydraulic plastic processing machines consist of several main parts:
Plasticization system
Responsible for plasticizing the material - dissolving and mixing it, and then pressing it into shape. The injection molding machine and its operating principle are based on the use of a screw, which feeds the material into a cylinder, where it dissolves under the influence of friction and high temperature.
Closing system
A highly durable system that is responsible for opening and closing the mold and keeping it tightly closed during injection. Its durability and stability are especially important when we have fast movements, heavy shapes and precision production.
Hydraulic systems
In hydraulic injection molding machines, hydraulic cylinders and pumps are responsible for moving the screw, mold and other elements. Hydraulic pumps create fluid pressure, which then transfers this pressure to hydraulic cylinders, causing them to move.
Control systems
The injection molding machines are also equipped with a touch screen control system, a temperature control system and a mechanical and pneumatic part release system. All these elements together create a complete machine necessary for the production of plastic products.
The injection molding machine operates through the interaction of multiple coordinated hydraulic boosters. Thanks to automatic control and monitoring systems, injection molding machines are capable of processing plastics with a very high level of accuracy and repeatability, which is necessary in modern production.
When and why should you choose a hydraulic injection molding machine?
Such equipment is indispensable in the production of polymer parts, when high locking force is required for the production of large and heavy products. In addition, the hydraulic type of injection molding machine is chosen when working with thick-walled and massive forms, which require significant effort to fill and maintain the form.
Such devices are indispensable when reliable operation under heavy and prolonged loads is required.
