Xi'an plastic bucket Whether the appearance is beautiful and the color saturation of the appearance is high will directly affect the customer's purchase intention and the product quality of the plastic bucket. This will bring unnecessary losses to customers and manufacturers.

1. Mold reason

1) The cooling system of the mould leaks, and the sealing system is corroded and damaged due to the long-term operation of the mould. Water leaks at various parts of the mold. Water leakage flows into the mold, causing the barrel wall to darken. The sealant strip needs to be replaced to ensure that the water leakage problem is solved.

2) The mold exhaust system is not good, and too much gas is trapped in the mold during production, resulting in poor gloss. Therefore, the mold exhaust system should be checked and repaired in time.

2. Raw material problems

1) First, understand the performance of raw materials and adjust the process formula reasonably. For example, the poor fluidity of the sol after the raw material is heated will lead to the brightness of the barrel wall appearance. We can properly add some low-pressure resin and raise the temperature of the can body to solve the problem.

2) Due to the external influence, the raw material has a large amount of moisture, which will produce a large amount of water vapor in the production process, leading to the darkening of the barrel wall in the production process. This problem can only be solved by drying the secondary raw materials.

3) The proportion of recycled materials added in the production process of Xi'an plastic barrels is large, resulting in the decline of the brightness of the barrel appearance. Methods The problem was solved by reducing the proportion of recycled materials and adding low pressure resin appropriately.
