Double screw angle line

I. Introduction
The traditional method of angle line is double screw granulation and single screw extrusion. Taking into account the small amount of corner extrusion, suitable for single screw extrusion. In addition, two of the mold in the traditional process there are synchronous problems, making double screw angle line process can not be extended for a long time.
The past two years, with the mold manufacturing accuracy continues to improve, as well as the continuous improvement of mold opening process, so that double screw angle line gradually mature. Many corner manufacturers begin to pay attention to the new process, and begin to try the double screw to do the corner line. In practice, fully enjoy the double screw production line of convenience, but also gradually won the recognition of our customers.
Two. Features
1. double screw does not need granulation, so that labor, electricity costs greatly reduced, and improve the market competitiveness of products.
2. double screw production angle line forming cycle is short, easy to control the quality of its finished products.
3. double screw will greatly increase the production of angle lines, save labor, electricity, and improve the cost performance of products.
4. double screw mixing, compression and melting fully, the same formula cost angle line toughness and rigidity greatly improved.
Three. Way
There are two main ways to make the angle of double screw, one is vacuum pumping, the other is water tank cooling. Vacuum way for a two, twenty-four hours output can reach 2-3 tons, the drawback is that the corner of the surface is not bright, suitable for the surface of the film line. The tank is cooled by four out of one and four corners at the same time. Its characteristic is that the angle line surface is bright, but the shortcoming is the output is low.
