Injection molding is a shaping technology for thermoplastics, thermosets and metal with a relative low melting point. This article is In particular, about thermoplastics here.
With injection molding,( provide by an injection molding company ) plastic material which is being supplied as granules or powder, to a viscous melted mass, and this is injected under high pressure into a mold, the cavity (or cavity), the shape of the desired product. By cooling the plastic material solidifies and one gets the desired product. Injection molding is one of the most widely used design techniques for plastic parts.
The molding process
A screw (in a cylinder) (1) presses the plastic (granulate) (2) through a small injection orifice (nozzle) (3) in the die (4 & 6). Herein, there is a cavity (cavity) (5). The now molten plastic flows through the injection opening and fills the cavities of the tool. Subsequently, it is cooled. As a result, the material solidifies and takes on the shape of the tool cavities (5). The mold is, after the material has sufficiently cooled down, opened by moving horizontally the upper part (6). The product is then printed by the ejectors (markers) from the opened mold (4). Gravity is the product from the mold in a container, or products that may not damage a robot picks them from the mold. After it is closed again can be started on the next production run.
