<p>The precision<a href="https://www.hisson.com/product" rel="noopener noreferrer" target="_blank"><strong> injection molding machine</strong></a> is a machine and equipment suitable for the production of precision plastic products. So how to determine that this injection molding machine is a precision instrument. The following will be discussed.</p><p> </p><p>Usually there are two basic indicators for precision injection molding machines, one is the deviation of the finished product size repeat, and the other is the deviation of the finished product repeat weight. The former is because the size and thickness of the finished product are more difficult to compare. The latter represents a comprehensive level of injection molding machines. The weight repetition error of ordinary injection molding machines is about one percent, and the more sophisticated instruments can reach 0.8 percent.</p><p> </p><p>More precise injection molding machines also require injection molding machines with higher injection pressure and higher injection speed. This requires the pressure, flow, temperature, etc. to be accurate to a corresponding accuracy, to ensure the reproduction of the finished product process and the accuracy of the product repeat.</p><p> </p><p>According to the instructions of the <a href="https://www.hisson.com/" rel="noopener noreferrer" target="_blank"><strong>injection molding machine manufacturer</strong></a>, when using the injection molding machine, the temperature of the injection molding machine should be prevented from being too high, because if the temperature of the injection molding machine is too high, it will cause greater harm.</p><p> </p><p>1. Excessive temperature of the injection molding machine will cause deformation of the machine due to heat, and its moving parts will be stuck due to the smaller gap between them, which will lead to poor work quality.</p><p> </p><p>2. If the temperature of the injection molding machine is too high, the viscosity of the oil will decrease and leakage will occur. Because the viscosity of the oil decreases and the lubrication effect becomes worse, its frictional resistance will increase, which will lead to increased friction.</p><p> </p><p>3. The high temperature of the injection molding machine will cause the rubber seal to deform. After the deformation, it will accelerate the aging, will reduce the characteristics of the seal and the service life, and cause the leakage of the medium.</p><p> </p><p>4. If the temperature of the injection molding machine is too high, it will accelerate the deterioration of the oil due to oxidation. This precipitate can block the small holes and the valve, causing the valve to be stuck and unable to perform normal work.</p>
