Repair of the barrel The inner surface of the barrel is harder than the screw, and its damage comes later than the screw. The scrap of the barrel is the increase in the inner diameter due to time wear. Its repair method is as follows: 1. For the barrel with increased diameter due to wear, if there i... Read More
The combined working quality of the two parts of screw and barrel has an important influence on the plasticization of materials, the quality of products and the production efficiency. Their work quality is related to the manufacturing accuracy and assembly clearance of the two parts. When the two pa... Read More
1. Check out the debris in the plastic guess. Generally speaking, there is no debris in the fresh plastic purchased originally, but through transportation, weighing, drying, color mixing, especially the addition of recycled materials, it may be mixed with debris. It is as small as metal scraps, as l... Read More
1. Each plastic has an aspirational plasticization processing temperature scale, and the barrel processing temperature should be controlled to make it close to this temperature scale. Granular plastics enter the barrel from the hopper and firstly reach the feeding section. Dry friction will inevitab... Read More
The screw of the extruder and the screw of the injection molding machine are both plastic processing machinery. They sound a little similar, but they are actually different. There are many differences between the plastic extruder screw and the injection molding machine screw. The following will be i... Read More
