Plastic injection molding is a process that forces liquid plastic into a mold to make custom plastic name plates, plaques, signs and product branding elements. Once the plastic cools and solidifies, it releases from the mold to form a variety of plastic parts for any industry. Popular uses of injection-molded include: appliance name plates, name plates for industrial equipment, car emblems, vehicle branding and license plate holders, as well as product identification for recreational products.

Injection-molded plastic name plates and other components are produced by a machine that consists of three basic components:

A mold which can be made to manufacture any size and shape that is needed
A clamping unit that clamps and holds the mold together throughout the whole process
An injection unit will then inject molten plastic into the mold, where it will remain until it has sufficiently cooled and released
The molten plastic used for injection-molded products is produced by melting small plastic pellets, which are fed into an injection machine heating the pellets to a molten or liquid form.

Once the now molten plastic pellets reach a predetermined temperature the semi liquid is forcefully injected into a mold. The speed and pressure of this process is controlled by a hydraulic cylinder that, once engaged, forces the liquid plastic into the mold.

In "dwell" phase of the plastic injection molding process, the plastic is left in the https://www.ezb2b.com/ to ensure that it completely fills the mold and then allowed to cool to the point where it solidifies and the desired object is produced. It is then ready for secondary processes as decoration, sub assembly, or shipment.

The injection-molded plastic process allows manufacturers to produce custom plastic name plates and components that would be too costly to make as intricately by utilizing traditional machining methods. Injection-molded plastics also saves time and money by allowing many pieces of the same component to be made at the same time, from the same mold; each copy identical to the one before it. This process also reduces labor costs by minimizing the need for manual labor from employees. There is also nearly no wasted material, as any unused or left over plastic can be re-cycled to be reused in the process

The History of Plastic Injection Molding

Plastic injection molding originated with chemists in Europe and The United States who were experimenting with plastics. Originally it was done by hand and pressed into a mold using Parkesine but it proved to be too brittle and flammable. John Wesley Hyatt is the official inventor of plastic injection molding and the process has a rich history with brilliant minds.

John Wesley Hyatt was a creative inventor and developed the processing of celluloid plastics. This was an amazing feat for a young printer from Illinois who took on the challenge from the New York Billiards Company to replace the ivory that was used in billiard balls.

So began his career in plastics engineering as he and his brother Isaiah started making several mixtures for checkers and other objects. After some time trying various mixtures, John mixed nitrocellulose, camphor and alcohol together. He pressed these ingredients into a circular steel mold that was heated and allowed it to cool. When the material was removed from the mold, he realized that he had successfully created a billiard ball composed of plastic. Thus began the process of plastic injection molding.
