Home drinking water is a rigid and long-term development of the big market. 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

So, no matter for the injection molding machine manufacturer or user, how to ensure the stable and continuous production of the injection molding machine is a very worthwhile goal to achieve. From the user’s point of view, selecting the correct injection molding machine model and effectively implementing regular preventive maintenance is the easiest way to ensure that the injection molding machine can continue to work normally without interruption. The so-called preventive maintenance is a series of prevention and inspection, which can find out the potential danger of failure in advance and effectively prolong the working life of the parts.
Read more →Types of Injection Molding Machine is the basic plastic injection molding machine knowledge. We will talk about the injection molding machine types topic in two directions: injection molding machine driving technology and mechanism constructions. Fistly, we will talk the types of injection molding machines named by driving system`s technologe or method. There are Hydraulic Injection Molding Machines, Electric Injection Molding Machines and Hybrid Injection Molding Machines. Below table will show you these three types of injeciton moulding machine`s characteristic: Secondly, There are two types of injection molding machines that are classified primarily by the mechanism construction: horizontal type of injection molding machines and vertical type of injection molding machines. The current mainstream of injection molding machines is horizontal, and one of the factors is the difference in clamping

Here we would like introduce the cause and treatment of injection molding machine hydraulic oil leakage, and how to find out and fixed the oil leakage issues. 1. General overview Injection Molding Machine Hydraulic leakage is a common fault phenomenon in injection molding machines, mainly due to the pressure difference generated when the liquid flows in the hydraulic components and pipelines, and the existence of gaps between components. In addition, harsh working conditions will also have a certain impact on the sealing of the injection molding machine. Once the hydraulic system leaks, it will cause the system pressure to fail to build up, and the injection machine hydraulic oil leakage will also cause environmental pollution,

There are some precursory information will be shown when injection molding machines errors occurred. These precursory information is also called potential fault, which identifies physical parameters indicating that a functional failure is about to occur, functional faults indicate that the injection molding machine has lost the predetermined performance standards. The change of the injection molding machine errors rate with time is often called the tub curve. The failure rate of the injection molding machine is roughly divided into three phases: early fault, occasional fault period and lossy fault period. 1. Early fault period The injection molding machine is in an early failure period, and the failure rate is high, but the
Read more →The injection molding machine barrel and screw make up the extrusion system. Like the screw, the barrel also works under high pressure, high temperature, severe wear and certain corrosion conditions. During the extrusion process, the barrel also has the function of transferring heat to the material or transferring heat away from the material. A heating and cooling system is also installed on the barrel, and the machine head is installed. In addition, the feeding port should be opened on the barrel. The geometry of the feeding port and the selection of its position have a great influence on the feeding performance. The smoothness of the inner surface of the barrel, the grooves on the inner wall of the feeding section, etc., have a great impact on the extrusion
