Plastic is a kind of polymer material that can be molded into any desired shapes by applying heat and pressure to it. It has thermal plasticity and becomes malleable when heated. Because plastic becomes soft when heated, it is easy to process. It then hardens when it cools.
Injection molding is a type of molding that takes advantage of this characteristic. Plastic that has melted at high temperatures is injected into a mold and cools to form molded products. Probably two-thirds of today's molded products are made by using this method.
The dedicated robots that take the plastic out of the molds are called take-out robots. Nowadays, many injection molding machines are equipped with take-out robots. These robots not only take the molded products out of the mold, but also transfer them to subsequent processes. For example,take-out robots can take products from the mold and then put them on conveyor belts. Conveyor belts move products to the inspection station for workers to inspect.
Take-out robots are gradually applied to performing more and more functions.
