The difference between parallel and cone bai twin screw extruder du 1. Diameter: The diameter of the parallel twin screw is the same, and the diameter of the small straight end of the conical twin screw is different from the diameter of the big end. 2. Concentric distance: the center distance of the flat twin screw is the same, the two axes of the conical twin screw are at an angle, and the size
The conical twin-screw extruder has the characteristics of uniform plasticizing and mixing, high output, stable quality, wide range of adaptation, long service life, and direct struggle of PVC. Equipped with corresponding measuring head die and auxiliary machine, various thermoplastics, especially PVC powder, can be directly extruded from tube sheets, rods, films and special-shaped plastic product
What points should be noted when plasticizing the barrel screw? There are two main treatment processes for barrel plasticization, one is heat treatment and the other is nitriding treatment, so when we carry out these two treatments, what points should we pay attention to? What points should be noted when plasticizing the barrel screw? 1. Check if toner is added to the raw material
Analysis of the causes and solutions of the slip of the injection molding machine barrel screw After using the injection molding machine barrel screw machine for a period of time, some users will find that they have encountered the phenomenon of screw slipping. Professionals said that the slipping situation is often caused by difficulty in pressing materials and the adhesion strength between
How to prevent the barrel screw from being worn? If there is a difference in the expansion coefficient between the barrel and the screw, the gap between the screw and the barrel will change, causing damage to the barrel and the problem of screw bite. How to prevent the barrel screw from being worn? "" The screw and barrel will wear due to the relatively hard and tough particles, so t
How to choose the screw of injection molding machine? For an injection molding machine, the screw is a very important component. In the operation of the equipment, it can play many roles, including melting, compacting, stirring, and applying pressure to the plastic. These processes require the use of all screws The rotation is completed in the barrel, so you must choose a good choice for this a
What are the factors that affect the plasticization of the barrel screw? The main factors affecting the plasticization quality of the barrel screw are: aspect ratio, compression ratio, back pressure, screw speed, barrel heating temperature, etc. 1. Length-diameter ratio: the ratio of the length of the screw to the diameter of the screw in the reasonable work of the screw. 2. Compr
How to improve the production efficiency of screw barrel The screw of the injection molding machine is an important part of the plasticizing part of the injection molding machine. The quality of the screw barrel is of vital importance for improving the quality and quantity of the products molded by the injection molding machine. How to improve the production efficiency of screw barrel
