The next step is to select the appropriate plastic material for the product. The mould is then machined to exact specifications using high-precision equipment. This involves creating a 3D model of the desired product and using this model to create the mould. The first step in the plastic injection moulding process is to design and fabricate the mould. The process of plastic injection moulding can be broken down into several stages, including mould design and fabrication, material selection, injection moulding machine selection, injection moulding, and post-processing. In the following years, the process was improved and expanded, leading to its widespread use in a variety of industries. He then went on to patent the first injection moulding machine in 1872. He was looking for a substitute for ivory, which was becoming scarce, and discovered that he could use celluloid to make billiard balls. Plastic injection moulding was invented in the late 19th century by American inventor John Wesley Hyatt. A Brief History of Plastic Injection Moulding In this guide, we will take a deep dive into the world of plastic injection moulding, including its history, the process, the materials used, and its benefits. This manufacturing technique is widely used for producing various consumer goods, including toys, packaging materials, household items, and automotive components. Plastic injection moulding is a process that involves injecting molten plastic into a mould, which then cools and solidifies into the desired product shape.
