Manufacturing of Plastic Pails or Buckets Plastic pails and containers are the most popular products used by individuals and companies for their requirements. Learn more about the making process in this article.

History of plastics can be traced back to 1800s when natural substances were combined with chemicals to form plastic products. Even though it was hailed as a revolutionary discovery, plastics did not become very popular because of its flammable characteristics. Polyesters, a much more polished version of plastics came into existence in 1833 while synthetic plastics arrived in the early 1900s. Today, plastic is one of the most used materials which are popular to make containers, plastic pails, bottles, and so on.

Raw Materials Required to Make Plastic Pails One of the chief ingredients is polymer which consists of organic molecules. Most plastics are derived from petroleum hydrocarbons and are created via a reaction between terephthalic acid and ethylene glycol. Ayva first step for creating the plastic pail is polymerizing the plastic or the polyethylene terephthalate. Once it is made, the plastic undergoes stretch blow moulding where a long parison of plastic is put into a mould, and a steel mandrel is inserted into it. Then pressurized air shoots are inserted via the mandrel which sets the mould. If you

want a flat bottom for your plastic pail, a separate bottom piece is inserted into the mould to achieve the flat surface look.

Manufacturing Process for Plastic Pails Before the pails are made, the plastic has to be polymerized which basically is a process where small molecules are combined with other larger substances. First the terephthalic acid is mixed with methanol and the reaction results dim ethyl terephthalate and water. Next step is when this solution is combined with ethylene glycol at 150 degrees Celsius which takes the form of another substance called bis 2hydroxyethyl terephthalate and methanol. The final step in this polymerization process includes the condensation of bis 2-hydroxyethyl terephthalate. After the plastic mixture reaches the required thickness, it is cooled to avoid discoloration. The pail is then removed from the mould and trimming is done to remove any leaks which happened during the manufacturing process.

The process for making plastic pails and other plastic products is very tricky and tedious. Hence, one should always seek professional help for making such products for personal or professional use.
