The second reason for the formation of adsorbed particles in the aluminum profile of the LED tube housing

The second main reason for the formation of "adsorbed particles" is as follow:

Influence of extrusion process

Whether the selection of extrusion process parameters is correct or not is also an important factor affecting "adsorbed particles". If the extrusion temperature is too high and the extrusion speed is too fast, the more "adsorbed particles" will be. The reason is that due to the high temperature and high speed, the flow speed of the profile increases, the degree of deformation of the mold increases, the flow of the metal is accelerated, and the deformation resistance of the metal is relatively high. weakened, it is more likely to form the phenomenon of sticking aluminum.
