Uneven spraying and insufficient air volume of the air cooler! Causing uneven heat dissipation and generating internal stress leading to brittleness! You can improve it by adjusting the melt volume of the extruder, adjusting the temperature of the hot air fan, and increasing the air volume of the cold air fan!
The air cooler produced by our company has a large air volume and an adjustable outlet temperature of 5-20 degrees, which is a good helper for you to solve problems.
