Types of plastic machinery
Characteristics of injection molding machine control system:1. 、 adopt advanced computer control of famous factory;2. self diagnostic fault function;3. direct input pressure, speed, time, travel and temperature data;4.LCD color liquid crystal display (pictured below);5. centralized lubrication;6. pressure coupling circuit saves power;7.24 V DC oil pressure directional valve coil never damaged;8. die cooling water regulator;9.M.C.B. insurance electrothermal control;10. advanced computer control system, large screen display, operation interface, easy to use cylinder;11. high-precision electronic ruler stroke control, accuracy up to + 0.1mm;12. improve reproducibility by using pressure and oil feedback;13. mechanical, electrical, hydraulic 3 heavy safety devices, in any case can ensure the safety of the operator (PD60-PD148 matching oil pressure);14. improve the reproducibility and operability by installing superior position sensors;15. using closed-loop control to achieve ultra precision forming.
There are many kinds of plastic machinery. According to the processing process is divided into extruder, injection molding machine and blow molding machine three major categories. In the screw extruder is under the action of the molten plastic extrusion through fixed shape extrusion, water cooling after cutting in the traction machine under the same section is mainly used for a variety of products. A large number of continuous production, such as pipe, rod profiles, also can be used for plastic modification and granulation.The basic mechanism of extrusion is simple - a screw rotates in the barrel and pushes the plastic forward. The screw is actually a ramp or slope that is wound around the center layer. The aim is to increase the pressure to overcome the greater resistance. Is an extruder, there are 3 kinds of resistance to overcome: solid particles (feed) on the cylinder wall friction and screw rotation before laps (feed) the mutual friction between them; melt in the cylinder wall adhesion; melt pushed forward when the resistance of the internal logistics.It is divided into single screw extruder and twin screw extruder. The injection molding machine is injecting molten plastic into the mold, cooling after the product. The use is very extensive, according to the different use of plastic, where is different. The injection molding machine is used in processing machinery and plastic processing industry the largest amount, not only a large number of productsCan direct production of injection molding machine, and it is composed of injection stretch blow moulding equipment key.
