Hydraulic Injection Moulding Machines

Hydraulic transmission of ZOWEITE® hydraulic injection moulding machine made in China: it takes hydraulic oil as the working medium, changes the mechanical energy of prime mover into the pressure energy of hydraulic oil through the power element (oil pump), and then converts the pressure energy into mechanical energy through the control element, and then drives the load to realize straight-line or back movement with the help of actuator (oil cylinder or oil motor).

Hydraulic transmission of Hydraulic Injection Moulding Machines: it takes hydraulic oil as the working medium, changes the mechanical energy of prime mover into the pressure energy of hydraulic oil through the power element (oil pump), and then converts the pressure energy into mechanical energy through the control element, and then drives the load to realize straight-line or back movement with the help of actuator (oil cylinder or oil motor). The force and speed of the actuator are adjusted through the remote control of the control element and the flow conditions. When the outside world disturbs the above system, the output of the actuator generally deviates form the original setting value, resulting in a certain error.

● What is the hydraulic control of Hydraulic Injection Moulding Machines

● The hydraulic control of Hydraulic Injection Moulding Machines is the same as hydraulic transmission. The hydraulic system also includes power components, control components and executive components, which also transmit power through oil. The difference between the two is the hydraulic control feedback device. The function of the feedback device is to feed back the output of the actuator(mechanical quantities such as displacement, speed and force) and compare it with the input(which can be variable or constant). The thicker deviation the output of the actuator change or remain constant. It is a closed-loop hydraulic transmission system, also known as hydraulic servo system or hydraulic servo system.

● The transmission system of Hydraulic Injection Moulding Machines uses on-off or logic control elements. Its control purpose is to maintain the stability of simple change direction of the set value, also known as set value and sequence control elements.

● Servo control elements are used in the control system of the hydraulic injection molding machine, which has feedback structure and is controlled by electrical devices. It has high control accuracy and response speed, and the controlled pressure and flow often change continuously. The output can be amplified.

● Proportional control is a kind of control between the above two. The proportional control valve used is an electro -hydraulic control element developed on the basis of on-off control element and servo control element. It combines some characteristics of the above two types of elements, and the on-off control used for manual adjustment can not meet the requirements. However there is no need for the servo valve to meet.

● What is the production process of Hydraulic Injection Moulding Machines?

● The ZOWEITE® Hydraulic Injection Moulding Machines uses a hydraulic cylinder to clamp the two halves of the mold together under high pressure. The plastic substrate particles 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 parts are removed and the process is repeated.

● To prevent the mold from being pushed open by injection pressure causing excessive material to “flash” around the parts, the clamping unit of Hydraulic Injection Moulding Machines must be able to supply enough locking force to keep the mold shut during injection. Roughly 3-4 tons of clamp force per square inch of cavity is needed for parts with thin wall sections and deep draw depths. For thick wall sections and shallow draw depths, about 2 tons per square inch is needed.


Today’s Hydraulic Injection Moulding Machines are able to control clamp forces up to and exceeding 8,000 tons and can create parts weighing in at more than 50 pounds. Hydraulic molding is a popular choice for the automotive industry, which requires the production of large, heavy parts such as bumpers. Like our machine GF2300 injection molding machine is a specially designed machine for plastic car bumper.
