  Plastic extrusion equipment is used in the process of plastic processing and production. The occurrence of plastic defects is also very troublesome. So what is the cause of this phenomenon and how should we deal with it? The answer is as follows.
  
  1. Plastic extruder has the following forms of poor plasticization:
  
  The main results are as follows:
  
  (1) The toad skin phenomenon exists on the surface of the plastic layer.
  
  (2) The temperature control is low, the meter pointer reflects the low temperature, and the actual measured temperature is also low.
  
  (3) The plastic surface is black with small cracks or small particles, but the plasticization is not good.
  
  (4) The plastic seam is not good, and there are obvious marks.
  
  2. Reasons for poor...    less

  1. Due to the low air or oil pressure, the automatic screen changer of the rubber extruder will be slow or even inoperable. In addition, the air and oil leakage of the cylinder and the hydraulic station will also cause this problem. . Facing this kind of problem, the relevant operators need to check the sealing condition of the power system of the screen changer and the air cylinder or hydraulic cylinder to avoid the recurrence of this kind of problem.
  2. When the torque of the extrusion system of the rubber extruder is too large and the main motor and the input bearing are not connected together, the safety pin or safety key of the rubber extruder may be cut off. At the same time, firstly check the preheating time and observe whether the heating value meets the requirements. Secondly, check the extrusion system to observe whether the screw is stuck by metal or other objects.
  3. In the daily work of the rubber extruder, sometimes the extrusion...    less

When the equipment is in production, some products need to use a vented rubber extruder for extrusion production, and some need to use a pin rubber extruder for production. We have to choose equipment according to the production process of the product. The screw length to diameter ratio of the rubber extruder is also designed according to different rubbers. Like the extrusion production of silicone rubber extruder, the silicone rubber extruder designs the extruder screw according to its production characteristics. The screw length to diameter ratio of the silicone rubber extruder is 1:14 or 1:16. The screw length-to-diameter ratio of the ordinary cold feed rubber extruder is usually 1:20. So we have to choose the rubber extruder according to the specific types of products and rubber types. Hebei Weiyuan Rubber & Plastic Equipment Co., Ltd. is a manufacturer...    less

  Why Does the Rubber Extruder Overload?

  The rubber extruder overload is a descriptive term for a state or condition where the main motor driving the extruder is surpassing full load.

Although potential factors that result in an extruder high motor load are listed below, it is possible that the main cause is simply that an under-powered drive motor was supplied for the application. If many of your products are pushing operating parameters to near the full load mark, I would suggest considering installing a larger motor. It is advisable to contact the extruder manufacturer to make sure that larger motors can be installed without exceeding the design limitations of the complete drive system. A guide to trouble-shooting excessive motor loads includes the following checklist:
  
  •
  Ensure that the dry feed system is delivering the correct feed rate and that the feed rate is consistent. Excessive dry feed rates can lead to high motor loads.
  
  •
  Lack of adequate process steam injection into the extruder barrel can also result in high motor loads....    less

  Controls Are Available For The Feed Zone Of Epdm Extruder

It is an important part of the overall extrusion process. There are specific controls that can be adjusted to control the feed and forward conveying of the plastic through the barrel of the extruder.
  
  The feed zone has several control variables affecting the forward conveying of the plastic. These are:
  
  The method of feeding the plastic into the extruder
  The feed zone temperature
  The screw temperature
  Extruders can be filled with plastic raw material in two ways. They can be flood-fed or starve-fed.
  
  Most single screw extruders are flood fed. This means they rely on gravity to entirely fill the feed section of the screw with the raw material.
  
  Extruders can also be starve-fed. This means the plastic raw material is fed into the extruder at a metered rate. Starve feeding can provide a more consistent feed rate. It is sometimes done to eliminate a surging problem.
  
  The...    less
