Today,Jason Mould tell you something about plastic injection molding: past, present and future.
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:
1.
A mold which can be made to manufacture any size and shape that is needed
2.
A clamping unit that clamps and holds the mold together throughout the whole process
3.
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 mold 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
