The history of plastic molding dates back to the 19th century, when the first synthetic plastic was invented. This plastic, known as parkesine, was created by Alexander Parkes in 1856 and was made from cellulose treated with nitric acid.
In the early 20th century, further innovations in plastic molding occurred, including the development of Bakelite in 1907 and the creation of polyethylene in 1933. These new plastics were stronger and more durable than parkesine, and they quickly found a wide range of uses in various industries.
During World War II, plastic molding technology advanced even further, as the need for lightweight and durable materials for military equipment increased. After the war, plastic molding became an integral part of many industries, including automotive, packaging, and consumer goods.
Today, plastic molding is an essential part of many manufacturing processes, and it continues to evolve and improve through the development of new technologies and techniques. From its humble beginnings in the 19th century, the plastic molding industry has grown and flourished, becoming a vital part of modern life.
