Generally, after using the air-cooled chiller for a long period of time, some problems cannot be avoided. If there is a failure, we should carefully check the operating conditions of the various parts of the injection machine. The main points are to check the refrigeration system, electrical system, air system, and water system. To judge whether their homework is normal, the editor …

injection molding conditions is the important thing for workshop owner to master. Injection molding is an industry with a wide range of knowledge, technology and practice. Plastic raw materials, toners, nozzle materials, molds, injection molding machines, peripheral equipment, fixtures, sprays, various auxiliary materials and packaging materials are used in the injection molding production process, which brings a lot of work to the management …

Injection molding machine basic structure is really important for businessman. According to the requirements of the injection molding process, the injection molding machine is a model with strong mechatronics. It is mainly composed of injection parts, clamping parts, fuselage, hydraulic system, heating system, control system, feeding device, etc. At present, common ear injection devices have single-cylinder type and double-cylinder type. …

The screw fracture temperature is also related, but it is rare, almost all of the screw itself is of poor toughness, or the screw has been used for a long time, refurbish the screw! The injection molding materials are rough. For example, adding GF [glass fiber] to the injection molding materials is the most expensive screw and machine! This injection molding material has poor …

The effect of back pressure on injection molding is very important, and it directly affects the filling of the melt and the quality of the plastic parts.   (1) Proper back pressure can improve the quality of products   ①It can compact the melt in the barrel, increase the density, and improve the injection volume, product weight and dimensional stability;   ②The …

1. Preparations before starting the china injection molding machine 1. Wear the safety protective clothing prescribed by the workshop before starting production. 2. Clean up the environment around the equipment, and don’t store anything unrelated to production. 3. Clean up the debris inside and outside the workbench and equipment, wipe the injection seat guide rail and the tie rod of …

When using an injection molding machine, the possible failures of the hydraulic system of the injection molding machine are diverse. It is the result of a combination of many factors, and the dispersion is relatively large. Therefore, when performing fault diagnosis, it is necessary to analyze the factors that cause the fault one by one, pay attention to their internal …

How does the injection molding machine screw unusual sound slip to do If the screw begins to slip during the preforming phase, the axial motion of the screw stops as the screw continues to rotate. Usually the screw slip will lead to degradation of materials before injection molding.but also short shot, extended processing cycle and other product quality problems. Influence …

1: The die must be grinded after a long time use, after grinding the edge surface must be demagnetized, can not have magnetic, otherwise easy to occur blocking material. In order to find out which parts and components have been damaged and the degree of wear, the enterprises should make detailed records and statistics of their use, care (lubrication, cleaning, …

Causes and solutions of injection machine failures 1. The oil temperature is too high The abnormal increase in oil temperature may be caused by abnormal cooling system or high heat generated by oil pressure components during operation. 1. The cooling system is abnormal 1) The supply of the cooling system is insufficient, such as the water switch is not fully …

1. Control the production of defective products, (control defective products) 2. Improve mold efficiency, mold efficiency directly affects the amount of material used. 3. Control inventory to avoid inventory caused by excessive production. 4. Cultivate the concept of cost saving for technicians, and avoid too much waste when adjusting the injection molding machine. 5. Confirm the change of the product …

1.The area of the mold opening hydraulic ring is too small Mold opening force = mold opening oil pressure ring area × mold opening oil pressure If you want to increase the mold opening force when the maximum pressure is determined, you can only increase the mold opening oil pressure ring area, and you can increase the mold opening oil …
