Plastic drums are usually small and medium-sized portable round containers used to transport or store a small amount of various materials. Despite exceptions, they are usually smaller than plastic pools. They are also usually larger than plastic bottles, although there are exceptions. They can be large enough to transport emulsifiers on a commercial or industrial scale, or they can be small enough to make beach sandcastles.
Considering the reusability, light weight and low cost of plastic drums, the service life of some plastic drums may include both. However, if the plastic bucket is initially filled with consumer goods, this possibility is even greater. Most plastics are easy to recycle, which makes them attractive materials for container construction because many containers only need to be shipped or shipped once. Plastic containers are used in almost all industries, many of which are designed as buckets.
The entire manufacturing process of plastic containers includes blow molding machines or injection molding machines. Many buckets are made of high-density polyethylene. HDPE is a durable, non-reactive thermoplastic that can withstand impact and severe weather during transportation or storage. During the blow molding process, the original HDPE resin (called raw material at the beginning of the molding process) is loaded into the hopper. Then, the hopper feeds the material to the feed channel, where the large screw pushes the material toward the mold. As the screw rotates, friction and pressure work together to heat the paper.
This heating is combined with the additional heat provided by the heating element along the channel to heat the raw material to a liquefied state. At this time, the liquefied billet enters the cavity and is shaped. Compress one
