Explore the causes of uneven color distribution of colored endurance boards
In order to meet the requirements of different users, the color of the endurance board is not constant, it has many colors. However, during the production process, it was discovered that the color distribution of these brightly colored endurance boards was uneven. Let's explore the root cause.
The reason why the endurance board has a variety of colors is because different color masterbatches are used, so the uneven color distribution is mostly because of the color masterbatches. Caused by poor diffusion. Since the thermal stability of the color masterbatch is relatively poor, in order to stabilize the color of the board, the production conditions must be strictly regulated, especially the material temperature, material quantity and production cycle.
In addition, for colored endurance boards like this, try to ensure that the cooling rate of each part of the extruder is consistent. In any case, the shape and position of the endurance board may cause local chromatic aberration, so it needs to be corrected.
