The technology of mixed color injection molding machine has developed rapidly for decades, which is not only reflected in the wide application of many new processes and technologies in production. Such as: mixed two-color injection molding, mixed three-color injection molding, mixed multi-color injection molding, etc., more importantly, people's understanding of mixed color injection molding technology and the degree of mastery have made a leap. Modern color injection molding production is a large-scale continuous operation of the manufacturing method, due to the participation and participation of high technology, mixed color injection molding production method from the initial manual operation gradually transformed into group production. The production process has gradually realized mechanization and automation, and is developing in the direction of only mechanization and collectivization. To realize automatic color injection molding operation, reflecting the advantages of safety, efficiency, material saving, etc., has been the development direction of color injection molding. Mixed color injection molding, as a very important processing method in modern industry, is used to produce a variety of mixed color plastic products, with many unique advantages, its molded plastic looks beautiful, high production efficiency in the production process, is a kind of advanced manufacturing technology that can not be compared with other processing methods and can not be replaced, and has a strong competitiveness in the manufacturing industry. It is widely used in the production of plastics with appearance requirements. The basic theory of mixed color injection molding has been formed. Based on mixed color injection molding products, centered on the mold, combined with the application of modern advanced technology, stimulated and promoted by the huge market demand for products, mixed color injection molding technology plays an increasingly important role in the development of the national economy, the realization of modernization and the improvement of people's living standards

Contact switch (contactless stroke switch) instead of contact stroke control and limit protection, can also be used for high-frequency counting, liquid level control, etc., with stability, reliability, long life, repeated positioning, adapt to the harsh working environment and other advantages. Mark: PRS vertical machine adopts proximity switch to control slide stroke. (a) Electronic ruler is a resistive displacement sensor, whether it is also called a resistance meter. Logo: POS. Its working principle is: using the principle of rheostat, the line displacement is converted into the rheostat of the sensor, and converted into a voltage signal. In addition to Shunzhan horizontal injection machine, other models all use electronic ruler to detect the displacement of screw, template displacement and ejector rod displacement, so as to achieve speed control.

A thermocouple is a temperature detection component that detects the temperature at each location. It is marked with: BTT/C. Operation principle: Weld two conductors of different materials, or A and B semiconductors, to form A closed ring, when the dependence temperature difference of the two conductors A and B, due to the thermoelectric effect, electromotive force is generated between the two, and a current is formed in the loop. The working end is placed in the measured medium, the temperature is t, and the other free end of the two-color injection molding machine parameter is under constant temperature. At the working end, when the thermoelectric potential changes, the thermoelectric potential also changes, the thermoelectric potential is input to the display instrument, recorded or closed on the microcomputer for processing to obtain the temperature value.
