Corrugated Plastic Box Wholesaler Introduces What Problems The Hollow Board Will Encounter

Corrugated Plastic Box Wholesaler introduced why the hollow board has uneven color:

1. The cooling rate is inconsistent during the production of the hollow board. The production of hollow boards is good to ensure that the parts are kept consistent at the cooling speed, and the parts with a large difference in wall thickness can use coloring agents to cover the color difference, and the parts with relatively uniform wall thickness are gentle on the material. The mold temperature needs to be effectively controlled.

2. The resin is impacted and whitened, and the plastic hollow board contains resin, causing whitening. Shenzhen hollow board material pressure, wounds, processing (blocking) and other shocks, the places that have received great shocks turn white. 3. The colorant presents a bad phenomenon in terms of diffusion. This situation will simply lead to patterns and other conditions near the gate. 4. In terms of the shape of the part, the orientation will affect the filling of the plastic, causing some parts of the Shenzhen hollow board to show chromatic aberration. If the situation is serious, it needs to be repaired before it can be used. 5. Plastics or colorants have poor thermal stability. To ensure the uniform color tone of the plastic hollow board, the fixed production conditions must be strictly controlled, especially the amount of material, the temperature of the material, and the production cycle.
