Hot runner mold design is made to put into injection molding machine production, the choice of injection molding machine is quite important also. All of the injection molding machine automatic cycle ability, applicable to hot runner system. In the choice has the following relevant factors injection molding machine to consider:
1 the addition of hot runner hot runner mold, more block flow plate, so a corresponding increase in the thickness of the mold,  pay attention to select the injection machine installation height.
2 measurement of the volume of injection molding machines, to take into account the large volume of plastic flow in compression.
3the depreciation for the hot runner mold, injection molding machine to promote the continuous operation, start to reduce the use of multi-stage cycle.. Number of devices used to ensure the automatic operation of the mold, the first choice is easy to control the robot or the robot, such as:
1)the need to place the product insert, label or sheet until the mold.
2) extrusion of plastic parts or accelerate their ejection.
3) control the movement of plastic parts and accessories to reduce the startup time.
4)  heat the mold before starting the injection molding machines .

With the increasing demands for product appearance,electrical and electronic plastic parts become more complex in structure but also to keep the small size of the development. Precision injection molding technology in this area played a major role in the advanced precision molding technology greatly improves the quality of plastic parts, reliability, performance, reduce production costs and improve production efficiency, has great significance.
Injection technology is a method of manufacturing plastic products, the use of pressure injection of molten plastic into the plastic mold, cooling forming a variety of plastic parts you want to get a technical. Currently the most commonly used plastic is polystyrene. According to the International Mould & Plastic Hardware Industry Suppliers Association official Luo Baihui introduced, with the "3C" product development, precision injection molding precision injection molding machine as a key basic equipment, the size of the molding product repeatability, internal quality and repeatability and forming the three aspects of efficiency has been greatly improved. Compared to conventional injection molding equipment, precision injection molding machine really introduced for precise control products and precision production. Precision injection molding of plastics unit is to improve the quality of plastics, injection repeatability and quality of products within the three key components. Currently, the device mainly to the high-speed, high-voltage and fast response of the target development.

 Creep is a frequently phenomenon appeared in hydraulic transmission and it is abnormal. Slight creep will result in machine shakes; this phenomenon naked eye is very in cognizable.  But prominent flow will produce beats and a big distance movement. Creep phenomenon is not a good thing, so it is very important to eliminate creep phenomenon to improve hydraulic system stability and machine tool precision.
