What's the difference between an electric injection machine and an oil press?
The operating interface has different places! The electric screen is generally the touch screen parameter input, not color. Manual or press?. Anyway, it's hydraulic and electric.
Motor advantages: clean, sanitary, convenient, 5S, motor stability is good, because the use of servo motors, and servo motor itself is to rely on data to control, high accuracy. As long as the material temperature rises, you can produce immediately without waiting. Disadvantages: servo motor itself is not power, general motor fixedly no great tonnage, the largest tonnage motor I contact is NISSEI NEX8000 (460T) has the advantages of hydraulic machine: pressure liquid itself is large, so the hydraulic machine power greatly, can be used in the production of precision and large parts, solid oil press more than 1000T a lot, but no motor. Disadvantages: hydraulic oil leakage, the biggest problem is that health is not easy to do. When starting in winter, there is a requirement for the temperature of the moving oil. Under normal circumstances, the temperature is low and the machine itself moves slowly and unstable. Generally, the temperature of the actuating oil should be controlled below 45 degrees.
Electric injection molding machine is a combination of electronic control and transmission of an integrated device, hydraulic press is only an action of the implementation of the body.The electric injection molding machine is small and easy to move. It is beneficial to the parallel production of many varieties and small quantities. It can save space, save energy, increase production flexibility and reduce the cost of comprehensive production.Electric injection molding machine the power system adopts full motor drive, and PLC, inverter and servo control technology, in order to achieve high precision control and substantial energy saving at the same time, to avoid the common hydraulic injection molding machine noise, heat and oil leakage phenomenon.Electric injection molding machine in injection molding structure, adopts screw plunger hybrid structure and PID temperature control, effectively ensure the stability of plasticizing and metering, from general resin to engineering plastics, injection molding can be of high quality, suitable for various fields of microelectronics, telecommunications, electrical appliances, instruments and automation devices, watches, toys and medical devices such as micro precision injection molding production.Hydraulic machine (a hydraulic machine) is a kind of special hydraulic oil as the working medium, through the hydraulic pump as a power source, by force to pump the hydraulic oil into the cylinder / piston through a hydraulic pipeline, then the cylinder / piston seal in several groups with each other, the different position of the seal is different but, all play a role in sealing, the hydraulic oil can not leak. Finally, through the one-way valve to make hydraulic oil in the tank cycle, so that the cylinder / piston cycle work, so as to complete a certain mechanical action as a productive force of a machine.
The motor has 4 servo motors, and the motor can speed up the cycle. Stability and other functions. Good motor. Anyone who has used it knows that the hydraulic press has 2 separate lines. It is the clamping circuit and the injection circuit
