The key to improving the production efficiency of plastic barrel: the purchase guide of injection molding machine barrel screw

The key to improving the production efficiency of plastic barrels: Injection molding machine barrel screw purchase guide In the plastic processing industry, injection molding machine barrel screw is one of the very important components. The correct selection and use of the barrel screw can significantly improve the production efficiency and product quality of the plastic barrel. This article will introduce a barrel screw -- 45 cone double, and provide you with injection molding machine barrel screw purchase guide. The 45 cone double barrel screw is a high-quality screw specially designed for injection molding machines. It adopts a 45-degree taper design, which can provide a larger screw length and increase the mixing time of molten plastic, thereby improving production efficiency. At the same time, the 45 cone double barrel screw also has better plasticizing effect and uniform plastic distribution, which can produce higher quality injection products. So, in the purchase of injection molding machine barrel screw, we should pay attention to what factors? First of all, to consider their own production needs of the barrel screw specifications. The production of different plastic products requires different screw diameters and lengths. Too large or too small screw diameter will affect the plasticizing effect and production efficiency. The choice of screw length needs to be determined according to the injection capacity and barrel length of the injection molding machine. Secondly, to understand the material of the barrel screw. The barrel screw is usually made of high-strength alloy steel or stainless steel to ensure its wear resistance

What is the role of injection molding machine barrel screw

The barrel screw of the injection molding machine will be damaged during use. You can surfacing wear-resistant aluminum alloy in part of the screw teeth of the barrel screw of the injection molding machine, or you can improve the wear resistance and corrosion resistance according to the size of the screw. Of course, this method generally has special standards, and the production and processing costs are very high. The barrel screw of the injection molding machine is an indispensable part of the injection molding machine.

The screw of the injection molding machine barrel has good mixture melting.

The liquid raw materials are added to the barrel screw extruder according to certain preparation, and the polycondensation reaction is generated under the influence of stirring and tooth combination, and the excess combustion heat is emitted according to the barrel. Basically, 95% of the twin-screw extruders are all used for the production of final granular products such as mixing, stripping back, reflecting extrusion, etc. The requirement for product dimensional stability is low. The twin-screw extruder can also closely combine mixing and molding. According to the use of specific engines and suitable mid-and downstream machinery and equipment, finished products can be produced in a more effective way, which can produce plastic films, plates and pipelines.

Comparison and difference between injection molding machine barrel screw and extruder screw

There are many differences between the barrel screw of injection molding machine and the extruder screw. The following is a brief introduction to the comparison and difference between the barrel screw of injection molding machine and the extruder screw. Injection molding machine barrel screw and extruder screw on the processing data are also different, the viscosity of the material is not the same. The barrel screw of the injection molding machine requires that the plastic raw material can flow in the mold, and the extruder screw is generally bent and narrow, so the fluidity of the plastic raw material must be better.

What are the methods to improve the performance of injection molding machine barrel screw?

Injection molding machine barrel screw performance improvement method: When inorganic minerals slide at high speed on the surface of the injection molding machine barrel screw, the scraping effect is not small. Therefore, the injection molding machine barrel screw speed should not be adjusted too high. Remove moisture, the moisture contained in the plastic has a certain impact on the wear of the screw surface of the injection molding machine barrel. The damage of the debris in the plastic to the barrel screw of the injection molding machine is self-evident (the cylinder will also be damaged at the same time). Therefore, a magnet bracket must be installed to strictly manage and monitor the material.
