First, like some products with high surface requirements, wire cut wire cutting technology can be used to improve extrusion marks, and the die produced by wire cutting has smaller tolerance and more accuracy.

Second, the post-polishing of the mold is also a test. Good polishing will also affect the surface effect of extruded profiles. A good mold polisher can earn more than 10 thousand a month, which proves the importance of mold polishing.

Thirdly, the control of temperature and speed in the extrusion process is also an important factor to determine the extrusion lines on the surface of extrusion profiles. If the speed is slow, the corresponding extrusion line will be improved, but at the same time the efficiency is not high and the output is low; If the temperature is too low, it is easy to block the die and the extrusion lines are obvious; It is easy to deform and fracture when the temperature is too high.

Written in the back, extrusion profiles must be of good quality, and of course they cannot be separated from advanced equipment. A machine of tens of millions and a machine of hundreds of thousands speak for themselves. It is not unreasonable to say that "if a worker wants to do a good job, he must sharpen his tools first."
