injection molding machine

  In the plastics processing industry, the   vertical injection molding machine   is the most used injection molding equipment. The output of vertical injection molding products accounts for more than 30% of the total plastic products. It is characterized by easy production automation, a short production cycle, and adaptability. Robust and high-end production power, but the vertical injection molding machine has a problem working, which is generally a process problem. What are the influencing factors of the vertical injection molding machine not forming? 1. The injection speed is slow, and the injection speed has a very prominent meaning for some of the shape messy, the thickness change, the finished product with a long process, and the high viscosity plastic such as the resistant ABS. When the high pressure can not be used to fill the finished product, a high-speed injection can be considered to solve the shortcomings of filling dissatisfaction. 2. The injection pressure...

Why is the extrusion volume of the   high-speed injection molding machine   too small? Some customers often report to us that the extrusion volume of the high-speed extrusion injection molding machine will gradually decrease after a period of time, mainly due to the following reasons: 1. The first reason is that the mold surface is too cold because the cold air has been turned on for a long time. At this time, we have to check whether the rubber at the exit of the mold surface has been plasticized and melted. 2. The second reason is that the start-up temperature is too low. At this time, it is necessary to check whether the temperature of each part of the extruder and die meets the standard requirements. Although the outside temperature of each part has reached the standard, the heating time is insufficient. , It will cause the internal and external temperature to be inconsistent. Check whether the heater or thermocouple is damaged. If the electrical device is damaged, repair ...
