Xi'an plastic bucket It is mainly used for storing and transporting various liquids. They have good characteristics for packaging of special dangerous goods. They are not fragile, rusty and light in weight. They also have excellent oil resistance and strong corrosion resistance. It is mainly used for packaging dangerous goods that need heat insulation, moisture resistance, pressure resistance and corrosion resistance. The plastic bucket is mainly made of polyethylene, polypropylene, polyester and other plastics by blow molding, injection molding, blister and roll molding. It is mainly used for the storage of liquid and solid goods in chemical, pesticide, medicine, food, hardware, electronics, electromechanical and other industries. The specification range is 0.25l-220l open and close plastic bucket and 1000L container plastic bucket. It can be used for goods storage or transportation turnover. At present, the production capacity of plastic barrels produced by rotational molding process can reach 50 tons. Many people will reflect that the plastic bucket will become brittle after a long time, so how to prevent the plastic bucket from becoming brittle?

Plastic bucket manufacturer Fragile plastic buckets are sometimes used during use. The fragile plastic bucket is easily damaged, which is not conducive to long-term use. The embrittlement of plastic barrel is closely related to the selection of production mould, raw materials, production machinery and production process. Today, the plastic bucket manufacturer will introduce you how to prevent the plastic bucket from embrittlement from the production technology.

1. The temperature of cylinder and nozzle is too low, which needs to be increased. If the material is easy to degrade, raise the temperature of the barrel and nozzle.

2. Reduce the back pressure and rotation speed of screw preform to loosen the material slightly and reduce the plastic degradation caused by shear overheating.

3. Mold temperature is too high, and demoulding is difficult. The mold temperature is too low, the plastic is cooled too early, the fusion is poor, and it is easy to crack, especially polycarbonate and other high melting point plastics.

4. Cavity and core shall have proper demoulding slope. When the core is difficult to demould, the cavity temperature should be increased to shorten the cooling time. When the cavity is difficult to remove, reduce the cavity temperature and extend the cooling time.

Plastic bucket manufacturers can improve the above production process, improve product quality and prevent brittleness.
