How to produce bucket
If the plastic bucket can be manufactured by injection molding, the raw material used is high-density polyethylene or polypropylene plastic, and there must be a corresponding steel mold for the plastic bucket and a plastic injection molding machine. The molding process is as follows: First, the plastic raw material particles are added to the injection molding machine, the plastic is melted by the barrel heating and injected into the steel mold at high speed and high pressure. After cooling, the mold is opened to take out the product, and the burrs are trimmed to obtain the finished product.
If plastic hollow barrels (ie, small-caliber barrels) can be manufactured by hollow molding process, in addition to plastic raw materials, plastic extruders, plastic hollow molding machines, etc. are also needed. The molding process is: adding the plastic raw materials to the extruder, heating and melting by the extruder, extruding the molten parison through the die of the head, and then putting the parison into the mold, blowing in compressed air to make the parison close Mold cavity wall, take out the product after cooling and shaping, trim and remove burrs to get the finished product.
