The screw is the core component responsible for conveying, heating and mixing plastics in the blow molding machine. The coating or treatment on its surface has an important impact on the melting and mixing effect of the plastic in the blow molding machine. Its surface state is directly related to the extrusion process. plastic treatment effect.
The coating on the screw surface plays a key role in heat conduction and heat transfer during the plastic dissolution process. Using high thermal conductivity coating on the surface can enhance the heat transfer effect between the screw and the plastic, improve the heating speed and uniformity of the plastic, which is important for accelerating the heating process. The melting process of plastic is very important, especially in high-volume and high-efficiency production environments, to ensure the stable operation of the extrusion system.
More importantly, treating the screw surface can improve the wear resistance of the screw. During the working process of the blow molding machine, friction between the screw and the plastic is bound to occur. Having good wear resistance can effectively prolong the life of the screw. The service life of the screw can reduce maintenance costs to a certain extent and improve production efficiency.
