From the toothbrush that you simply use in the morning to the plastic-type 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 supplied a more efficient and productive approach to mass producing products that we make use of each and every day. Plastic mold injection functions by heating a plastic material and treating it into a mold cavity. This really is ideal because it can create stronger and more precise products. Previously, the process almost certainly involved large amounts of the plastic material which were stamped or cut out. This allowed for wasted plastic and decrease quality. Mold injection allows any leftover plastics to be melted again and reused.

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

Regardless of the product, whether small or large, a mould cavity can be created for it as well as an injection molding machine built for this. Whether it is a small plastic toy or a body panel for a car, the advantages of mold injection have changed the manufacturing processes since its beginning.
