injection molding machine

Why is the extrusion volume of the   high-speed injection molding machine   too small? Some customers often report to us that the extrusion volume of the high-speed extrusion injection molding machine will gradually decrease after a period of time, mainly due to the following reasons: 1. The first reason is that the mold surface is too cold because the cold air has been turned on for a long time. At this time, we have to check whether the rubber at the exit of the mold surface has been plasticized and melted. 2. The second reason is that the start-up temperature is too low. At this time, it is necessary to check whether the temperature of each part of the extruder and die meets the standard requirements. Although the outside temperature of each part has reached the standard, the heating time is insufficient. , It will cause the internal and external temperature to be inconsistent. Check whether the heater or thermocouple is damaged. If the electrical device is damaged, repair ...

What are the product characteristics and characteristics of the vertical injection molding machine?   MH is a   Vertical Injection Moulding Machine Manufacturers . Today, MH will introduce the characteristics of vertical injection molding machine to you. The vertical injection molding machine is controlled by a microcomputer. The power system is driven by oil pressure. The plastic is heated by an electric heating ring in the barrel and sheared by the rotation of the barrel screw, and then pre-molded and melted into the cavity. After cooling, the mold is opened. The product can be obtained by the ejection action, and the vertical injection molding machine can perform manual and semi-automatic production. Product features of vertical injection molding machine: 1. Vertical column-free clamping, horizontal injection, the mold is open on three sides, and the operation is more convenient and safe. 2. The injection pressure is large, controlled by a torque hydraulic motor, the screw ...

  With the development of the plastics industry, the use of injection molding machines is increasing. However, the noise of injection molding machines has always been one of the concerns of many manufacturers and users. So how to eliminate the noise of injection molding machines? Now let the  MH injection molding machine manufacturer  introduce to you. Causes of motor noise: 1. The motor bearing is damaged. 2. The coil winding of the motor is faulty. 3. The motor wiring is wrong, and the noise increases when the system pressure rises. Troubleshooting method: 1. Replace the bearing. 2. Replace or repair the motor. 3. Refer to the wiring diagram again for wiring. Causes of vibration pump noise: 1. The oil pump motor is installed differently. 2. The coupling is loose. 3. Internal failure of the oil pump. 4. The oil level is too low, suck in air into the oil from the oil filter or the joint connection. 5. Inhale air from the motor shaft. 6. The oil filter blocks the oil filte...

Screw-locking small fixture 丨   EDM manual fixture 丨 EDM small quick positioning tooling fixture. Today's mechanical processing industry generally exists:  1. Electrode design, manufacturing, and electrical discharge machining are scattered and poorly coordinated, which makes it impossible to quickly transfer and execute each process. 2. EDM machine tools are aging, and backward managers will only complain about the poor performance of the machine tools or the small number of machine tools, instead of tapping the potential of the equipment processing technology. 3. EDM ceramic tooling fixtures have always been manually checking electrodes, which is cumbersome and inefficient. 4. The design of the electrode is not standardized, and various standards have caused a waste of electrode material, which is a great disadvantage. 5. The electrode clamping efficiency is low, the electrode calibration time is long, the time for each electrode is long, and the recheck time is long. The po...

  Everyone knows that a  vertical injection molding machine  is a kind of machine that shapes plastics. It can process and shape plastics. It is a very common machine in plastics processing. However, the vertical injection molding machine needs to be operated in strict accordance with the safety operating regulations during the operation and use process. So, what are the safe operating procedures for vertical injection molding machines? MH is a  vertical injection molding machine manufacturer . Today, the MH injection molding machine manufacturer will introduce the detailed safety regulations of the vertical injection molding machine:  A. Preparations for the safety operation regulations of the vertical injection molding machine: 1. Check whether the parts of the machine and the electrical control box are in good condition. 2. Check the oil level of the hydraulic oil, whether the oil storage is sufficient, start the motor and observe whether the oil output from ...

  After using the   liquid silicone machine , it is easy to cause mechanical failure due to improper operation. In order to prevent chain mechanical failures, today the manufacturer of MH liquid silicone machine has listed the following points for attention. Customers are welcome to discuss and make progress together. First, after spraying with a liquid silicone machine, it is important to clean the liquid silicone in the injection machine. This is very important, because after it is used, the liquid silicone in the machine must have a lot of residue. If these residues are cleaned, it will affect the next use. The remaining residues will affect the new liquid silicone, so it is very important to clean the liquid silicone machine after use. Second, when the injection machine is in use, it is necessary to regularly check whether its injection head is in good condition. If the injection head fails, the degree of injection will be greatly affected. Therefore, it is necessary to en...

  The  LSR Liquid Silicone Rubber Machine  should pay attention to maintenance and maintenance to avoid the specific measures taken to avoid chain mechanical failures. Many users do not know how to maintain the liquid silicone machine. Today, the Minghui  injection molding machine manufacturer  will introduce to you how to maintain the LSR Liquid Silicone Rubber Machine. Good to increase the service life of the machine. ▲1. Maintenance of lubrication system Before each operation, it should be clearly stipulated that the daily lubrication points should be refilled with grease for good lubrication. If the machinery and equipment have a centralized lubrication system, the oil volume should be checked regularly every day, and the oil volume should be refilled before the lower limit is specified. Lubricating grease. Lubricating oil should be added to the required position before the machine is started up for the first time. After that, it can be added every three mon...
