What is an injection molding machine? It is the thermoplastic or thermosetting material using plastic molding mold to make plastic products of various shapes of the main molding equipment. Divided into vertica l, horizontal, full electric. The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to shoot out and fill the mold cavity. History of injection molding machine. The injection molding machine was invented in the United States in 1872 and has a history of 130 years, but the screw injection molding machine has been developed in the past 50 years and become the most commonly used injection molding machine in the industry today. At present in the engineering plastics industry, 80% of the use of injection molding. The

Shrinkage rate Forms and calculations of thermoplastic molding shrinkage As mentioned above, the factors affecting thermoplastic molding shrinkage are as follows: 1.1 Thermoplastics In the molding process, due to the volume change from crystallization, strong internal stress, large residual stress frozen in the plastic parts, strong molecular orientation and other factors, thermoplastics have a larger shrinkage rate, wide shrinkage range and obvious directivity compared with thermosetting plastics. In addition, the shrinkage rate after forming, annealing or humidification treatment is generally larger than thermosetting plastics. 1.2 Characteristics of plastic parts During molding, the molten material contacts the surface of the cavity and the outer layer is cooled immediately to form a low-density solid shell. Due to the poor thermal conductivity of plastic, the inner layer of plastic parts

For the traditional injection molding machine, how to expand the space of energy saving? The energy consumption of the machine is mainly reflected in the following parts: (1) Electric energy consumption of hydraulic system oil pump; (2) The power consumption of the heater; (3) Power consumption of circulating cooling water pump. The power consumption of hydraulic oil pump accounts for more than 80% of the total power consumption of injection molding machine. So, what are the energy-saving transformation methods of injection molding machine?

Household drinking water can be divided into plain boiled water, water purifier filtered water and packaged water. At present, the sales volume of packaged water is only 15.5% of the total drinking water volume, and the development space is broad. The quality of tap water and long-term trends determine the home packaged water space. Through the comparative analysis of Chinese and American tap water systems, it is expected that it is difficult to further improve the overall quality of Chinese tap water terminal, ana lod the domestic drinking water market will remain prosperous for ng time. The water purifier market has entered a bottleneck period, while the 100 billion level barreled water market is still growing

Appropriate control of the required injection molding pressure produces a great product with good quality. The injection pressure regulation and metering system is on the hydraulic injection molding machine, and all movements are performed by the oil circuit responsible for the following operations: 1. Screw rotation in the plasticizing stage. 2. Slider feeder (the nozzle is close to the nozzle bushing). 3. Axial movement of the injection screw during injection and pressure holding. 4. Close the base material on the injection rod until the toggle rod is fully extended or the piston mold clamping stroke is completed. 5.
