Here to emphasize that the screw and the barrel of these two important parts, one is the elongated screw rod, one is relatively small diameter and long holes, their machining and heat treatment processes are more complex, the accuracy of the guarantee will be compared difficult. Therefore, the wear and tear of these...

Injection molding machine screw is a long time in the high temperature, high pressure, high mechanical torque and high friction environment to work. The first few factors are required for the process conditions and the friction losses are inevitable. General screw surface nitriding have been carried out to improve the ...

Commonly used on the market with 45 steel screw, 40Cr steel (chrome), 38CrMoAIA nitriding steel. If your product is + glass fiber. With chrome when about 3 months will slowly fall off, the color difference. The best choice Nitriding. Stainless steel screw can not do + glass fiber. Generally non-special materials are...

First of all, we have to determine the parameters: length to diameter ratio, compression ratio, diameter, pitch, length, the model used brands, the number of,, the use of materials commonly used to understand the parameters. According to the different types of each, the use of each will be different according to the...

Screw rotating in the barrel, the friction between the material and the two, so that the gradual wear and tear of the screw and the working surface of the barrel: the screw diameter will be reduced friction, the inner diameter of the barrel due to friction increased. As a result, the clearance between the screw and the...

Corrosive, abrasive, and high temperature resistant resins may unknowingly damage the screw and barrel. For example, some engineered materials, thermoplastic elastomers, and biopolymers sometimes form a corrosive environment. In addition, reinforcing materials (such as glass fiber, glass ball, etc.), some fillers and...
