Benefits of Plastic Injection Molding

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.

Sunglasses are a good example of the benefits of mold injection. Many quality sunglasses will use mold injection to create their lenses and frames. This allows each lens to be nearly identical to the other, as they were both creating in a mold cavity. This is true with the pieces of the frame as well.

Regardless of the product, whether small or large, a mold cavity can be created for it and a injection molding machine built for it. Whether it is a small plastic toy or a body panel for a car, the benefits of mold injection have changed the manufacturing processes since its inception.
