ementary material to the mold cavity, and to ensure that products have a certain density and 5 dimensional tolerances). The basic requirements of the injection molded plastics, injection and molding. The plasticizing premise to achieve and guarantee the quality of the molded part, to meet the requirements of forming, injection must ensure there is enough pressure and speed. The same time, due to the high injection pressure, the corresponding cavity to produce a high pressure (average pressure of the cavity is generally between 20 ~ 45MPa), so there must be large enough clamping force. Thus, the injection unit and clamping devices are key ponents of the injection molding machine. Mainly in three aspects of the evaluation of plastic products, and the first appearance of quality, integrity, color, luster。 the second is between the size and relative position accuracy。 the third is to use the corresponding physical properties, chemical properties, electrical properties. These quality requirements are also different according to the different products using the occasion to require the scale. Defects of products is that the mold design, manufacturin g precision and wear. In fact, the technical staff of the plastic processing plants often suffer from the face of technology means to pensate for the problems brought about by the mold defects but not the effectiveness of a difficult situation. Regulation of technology in the production process is the essential way to improve product quality and yield. Injection cycle is very short, if the process conditions are handled badly, the waste will be an endless supply. Adjustment process when the best time to change a condition to observe a few times, pressure, temperature, time, all with the tone, it could easily lead to confusion and misunderstanding, a problem do not know what reason. Measures to adjust the process, means, in many ways. Example: solving products Note dissatisfaction there is more than a dozen possible solutions to choose to address the crux of the problem, two major programs, in order to really solve the problem. In addition, attention should be paid to the dialectical relationship between the solution. Such as: products the depression, sometimes to raise the melt temperature, sometimes to reduce the melt temperature。 sometimes to increase the quantity, and sometimes to reduce the feeding amount. To recognize the reverse feasibility of measures to solve the problem. Classification and characteristics Injection molding machine in accordance with the arrangement of the injection unit and clamping devices can be divided into vertical, horizontal and vertical and horizontal posite. Its own characteristics as follows: (a) the characteristics of vertical injection molding machine: 1, the injection unit and clamping devices in the same vertical center line, and the mold opening and closing along the upper and lower direction. Its covers an area of only about half of the horizontal plane, the。
