What are the different types of injection molding equipment?
Injection equipment, also called injection presses, injects molten plastics into the mold and then cools the plastic and extracts freshly produced parts. The device itself is often identified as one or more different types. Types of injection pressing equipment include vertical and horizontal presses, injection rollers and injection bolts, hydraulic and electric presses and other presses mentioned by the amount of pressure they can apply to molds. There are also warm and cold running pressing systems used with an injection device. This identifies the way in which the injection press holds the mold in the machine. For a given application, this may be a critical factor for the manufacturer. If the parts are large, gravity may be needed to help extract part from the machine. If the parts are small, you may need to extract horizontally on the table or another device for further production of parts.
the wayThe melted plastic is injected into a mold, it can also identify the type of molding device. Some species use a cylinder that collects molten plastic in the chamber, and then drives the piston down to the chamber to create pressure to insert plastic into a mold. The second system includes a long, heated barrel that contains a screw. The plastic is brought to one end and powered the barrel with a screw melting plastic as it goes. The pressure required to injure the plastic into the mold is not formed by a cylinder, but by the pressure created by the screw.
Some injection pressing device is identified as the pressure required to maintain different parts of the mold is set. In hydraulic systems, a number of hydraulic cylinders move pieces of mold and create pressure to keep them while plastic is injected. In other types of injection pressing devices, the forms are moved and held together by a number of electric motors. High pressure systems tend to use hydraulic and lower pressure systems tend to use electric;However, there is a wide area of overlapping where it can either be suitable for the application,
Forms used in injection can be two general types: hot runners or cold runners. Runners are passages in a form that molten plastic travels to achieve different chambers that they have to fill in to form part. If the forming device cools these runners, it is referred to as a cold runner system. If the runners are heating, the device is called Hot Runner System.
When defining injection devices according to the type in the plastic industry, the primary feature needed for the given application tends to determine how the machine is referred to. Those who use hot running systems often say they use the UNNER hot coating machine, although it is also horizontal and electric. Those who produce large plastic parts can refer to their machines as vertical, although they also have a hot runner and hydraulic systems. Since there are many types of injection molding devices, each equipment is in SKOTOne of many different types and can be unique, depending on the combination of the systems it has.
