How is the plastic bucket made?

- May 28, 2019-

If the plastic water bucket is used, the injection molding process can be used. The raw materials used are high-density polyethylene or polypropylene plastic, and the corresponding steel mold and plastic injection molding machine of the plastic barrel. The molding process is as follows: the plastic raw material particles are added first. In the injection molding machine, the plastic is melted by high temperature and high pressure injection into the steel mold through the heating of the barrel. After cooling, the mold is opened and the product is taken out, and the finished product is removed.

If the plastic hollow barrel (that is, the small-diameter barrel) can be manufactured by a hollow molding process, in addition to the plastic raw material, there must be a plastic extruder, a plastic hollow molding machine, etc. The molding process is: adding the plastic raw material to the extruder, After being heated and melted by the extruder, the molten parison is extruded through the die of the machine head, and then the parison is placed in the mold, and the compressed air is blown to make the parison close to the cavity wall, and the product is taken out after cooling and setting, and the burr is removed. Get the finished product.
