Detailed explanation of material properties of plastic bucket

First of all, it is necessary to understand the function of the material and adjust the process formula reasonably. For example, the poor fluidity of the sol after the material is heated will lead to the brightness of the barrel wall appearance. Some low-pressure resins can be added properly and the barrel temperature can be increased to deal with the problems accordingly. Due to the external influence on the moisture content of the material, the occurrence of a large amount of water vapor in the production process will cause the barrel wall to be dark and not bright during the production process, and the problem can only be solved by secondary drying of the material.

In the production process of plastic bucket, the reclaim material is added, which leads to a large share, resulting in the decline of barrel appearance brightness. This problem can be solved by reducing the proportion of recycled materials and adding low pressure resin properly. The cooling system of the mould leaks water. The long-term operation of the mould results in the corrosion and damage of the sealing system. The leakage occurs in a single direction of the mould. The leakage flows into the mould, resulting in the dull wall of the barrel. The sealing strip needs to be replaced to ensure that the problem of water leakage can be solved.

It is necessary to have certain strength and wear resistance, impact resistance, good heat-resistant parts, excellent chemical resistance and small water absorption. Only in this way can it be used and satisfy the requirements of transparency for a long time. Therefore, in the whole process of injection molding, we should pay more attention to the planning of materials, equipment, molds and even products, and put forward strict or even special requirements.

The reason why the plastic bucket can be deformed is that there are few control points for the wall thickness of the plastic bucket, which causes the barrel body to be uneven. Therefore, the standard of the plastic bucket is relatively loose when it is formulated. The wall thickness of the two symmetrical points of the example is allowed to be within the scale of 2:1. In this way, plastic buckets with uneven wall thickness are often considered qualified when they are analyzed again. In practice, the plastic bucket will be deformed due to the large difference between the thickness of the bucket wall.
