    The ** of single-screw extruder is about tens of thousands of yuan per unit, the cheap one is one or two thousand yuan, and the expensive one is one or two hundred thousand yuan. The first single screw extruder is affected by many aspects, such as brand, category, specification, market, etc. Before choosing to buy, it is necessary to understand and compare in many aspects.

    The single-screw extruder is mainly used for extruding soft and hard PVC, polyethylene and other thermoplastics, and can process a variety of plastic products, such as blown film, extruded tube, pressing plate, drawn ribbon, etc., and can also be used for melt granulation. The plastic extruder has advanced design, high quality, good plasticization, low energy consumption, and adopts involute gear transmission, which has the characteristics of low noise, stable operation, large bearing capacity and long life. If you want to know more about the single screw extruder and **, you can consult the company, thank you!

    I wonder if your new screw is for nylon? In addition, you can try to lower the temperature of the feeding section, if you want to change to a new screw barrel, you can find me.

    This is a common problem with LCP and PC. Do you do nylon will also have this problem? Where is your company? If it's close, I can help you take a look, I'm a vertical injection molding machine manufacturer. If you need it, come to me.

    You can see if there is plastic at the mouth of the barrel, if not, just knock the hopper with something and poke it with a thin iron bar.

    If the material particles are too large and can't go down the screw, insert the hopper with a long iron or knock the lower part of the hopper with something to make it vibrate, and the material will be OK when it goes down to the screw.

    Jinxin provides you with:

    1.If the new screw is not cut, it may be that the design of the screw is not appropriate, and some plastics need to use special screws.

    3.The plastic particles are too large, resulting in bridging phenomenon, and the plastic can be crushed again.

    4.The barrel discharge port is blocked, and it is checked if there are any melted plastic blocks stuck here.

    5.The temperature control is not accurate, and the temperature at the rear end of the barrel is too high.

    6.The screw and barrel are worn, resulting in plastic leakage and not being conveyed to the front end of the barrel.

    7.The screw is covered - the plastic wraps around the screw and rotates together.

    When the temperature is low, just adjust the temperature of the machine.

    You check whether the material port is blanking, if it is not blanking, it is a screw package, you should reduce the temperature of the first area of the barrel, and at the same time use slender plastic products or plastic film to forcibly stuff the screw inlet, and use a plastic rod to pound it into the screw groove, so as to remove the molten plastic wrapped in the screw; Secondly, check whether the pre-plastic motor is wired correctly to avoid causing the screw to reverse. If the screw material port is unloaded and cannot be stored, it is the nozzle flowing outward, and the nozzle should be pressed against the closed mold for pre-plastic storage. In addition, if the viscosity of the molten material is low, the back pressure of the screw is too large, which will also cause the material to be stored and cannot be stored, so the back pressure can be appropriately reduced.

    In short, when encountering a situation, it is necessary to analyze it specifically and find out the cause of the problem in order to solve the problem.

    Summary. The reason why the screw of the injection molding machine does not move: the melting temperature is too low and the temperature is not enough.

    It is possible to increase the temperature of the injection molding melt. The control valve line is damaged, and the damaged line is repaired from the new. If the ruler fails, replace the failed ruler.

    The back pressure is too large, the back pressure adjustment is divided into two ways, hand adjustment and electronic back pressure, the hand adjustment is a hand adjustment rotary switch, adjustable large and small, and the electronic back pressure can be completed by directly entering the number on the computer. When adjusting the back pressure when melting, you can observe the glue discharge of the nozzle or observe the back pressure gauge of the machine. The screw of the injection molding machine is stuck.

    Clean up the plastic residue inside the stuck screw.

    Can you tell us more about that?

    Specifically, depending on what the material is, there are many reasons, 1 The pressure is too small, 2 The back pressure is too large, 3 The melt temperature is too low, 4 Whether the solenoid valve is stuck, etc., The answer is in your etc., the reason is that the screw is stuck, and I have done a good job of the person who asked the question.

The low-pressure injection molding process is a packaging process method that injects the encapsulation material into the mold and quickly cures and molds (5 50 seconds) with a very low injection pressure to achieve insulation, temperature resistance, impact resistance, vibration damping, moisture resistance, waterproof, dustproof, chemical corrosion resistance and other effects. Henkel Technologies offers high-performance Technomelt series specialty hot melt adhesives for this process, which are mainly used in the packaging and protection of delicate and sensitive electronic components, including: printed circuit boards (PCBs), automotive electronics, mobile phone batteries, wiring harnesses, waterproof connectors, sensors, micro switches, inductors, antennas, ring cables, etc. >>>More
