Injection molding has changed the efficiency of manufacturing for many of the products that you use every day. From the toothbrush that you use in the morning to the plastic fork you used to eat your lunch. Even the sunglasses that you wear were probably created using plastic injection molding.
Plastic injection molding machines came about in the 1930's. They have provided a more efficient and productive method of mass producing products that we use each and every day. Plastic mold injection works by heating a plastic material and injecting it into a mold cavity. This is ideal because it can create stronger and more precise products. Previously, the process most likely involved large amounts of the plastic material that were stamped or cut out. This allowed for wasted plastic and lower quality. Mold injection allows any leftover plastics to be melted again and reused.

You may not be aware of plastic injection molding machines, but almost everything around us is made by means of Plastic Injection Molding. It is the most fundamental process in the manufacturing of plastic parts. It is done by shoving melted plastic in to a mold cavity until it cools and forms a specific plastic shape. Plastic injection molding is very effective when the plastic parts that need to be produced are too complex or expensive to do by machine. With plastic injection molding, many parts can be made simultaneously, using the same mold.
Injection molding is a rather a modern way to manufacture parts. It is a quick and swift process and is used to produce huge numbers of items like high precision engineering components to disposable consumer goods. It is often used in mass-production and prototyping. It helps in manufacturing such small products as bottle tops, toys, containers, model kits, etc.
