Injection molding is a manufacturing process that uses heated plastic to create objects of a fixed shape. The process is extremely versatile and can be used to create a wide variety of objects. In order to get the most out of injection molding, it is important to use the right tools and techniques. In this blog post, we will discuss the 4 ways to drive injection mold processing. Then explain how they work so you can decide which method is right for your business!
There are 4 main ways that injection molding machines can be driven: Electro-Hydraulic Drive, electromechanical Drive, Pneumatic Forming, and Extrusion. Each of these has its own advantages and disadvantages.
4 Ways To Drive Injection Mold Processing
1. Electro-hydraulic drive
Electro-hydraulic drive is the most common type of drive used in injection molding machines. It uses a hydraulic system to generate the power needed to operate the machine. Hydro-static pressure is generated by a hydraulic pump driven by an injection molding motor or a water pump. A hydraulic cylinder or piston connected to the moving part of an injection mold (such as a moving mold) is driven by the rated pressure produced by the hydraulic pressure transportation and control system. By producing pressure, the hydraulic pressure system controls the translation and direction of the rotating mold. Injection molded parts are made by further compressing the material once it has been formed. The advantage of this system is that it is very efficient and can be used to create very complex objects. However, the downside is that it can be expensive to maintain and repair.
2. Electromechanical drive
Electromechanical drive is another common type of drive used in injection molding machines. It uses an electric motor to generate the power needed to operate the machine. It is the electric motor that drives the transmission mechanism in presses, friction presses, roll forging machines, etc., to provide power and rotation, and to move the mold directionally. It also transfers the driving force onto the mold for injection molding of raw materials using sliders and other moving parts. The advantage of this system is that it is more affordable than electro-hydraulic drive. This system is less efficient than electro-hydraulic drive and can only be used to create simple objects, but it is much simpler and easier to maintain.
3. Pneumatic forming
Pneumatic forming is a type of injection molding that uses air pressure to drive the machine. It is typically used for smaller objects because it cannot generate as much power as the other methods. Generally used to process blisters and form molds. In other words, air pumps generate negative pressure when the mold is stationary. This causes the plastic sheet to be directly sucked onto the surface of the mold when the mold is in the fixed state. Blow molding is the process of creating a certain air pressure gas through an air pump. Blow into the cavity of the hot-melt plastic or hot-melt glass blank to expand, deform, and attach to the surface of the mold cavity to form a product. The advantage of pneumatic forming is that it is very cheap and easy to maintain. However, the downside is that it is not as precise as the other methods and can only be used to create small objects.
Extrusion is a type of injection molding that uses a screw to force the plastic through a die. It is typically used for larger objects because it can generate more power than the other methods.
Extrusion is a type of injection molding that uses a screw to generate the power needed to operate the machine. As the mold moves relative to the machine head, various parts are formed by the movement of the mold and passing through the mold through extrusion. Extrusion machine screws extrude plastic into the mold and pass it through the surface of the mold as plastic is extruded into the mold. Once cooled, the plastic is shaped into the desired profile. Continuous forming is carried out by pulling the extruded profile forward using the pull mechanism. The main advantage of this system is that it is very efficient and can produce a lot of power. However, the downside is that it can be quite expensive to purchase and operate.
4 ways to drive injection mold processing-conclusion
In conclusion, there are 4 main ways to drive an injection molding machine: electro-hydraulic drive, electromechanical drive, pneumatic forming, and extrusion. Each of these has its own advantages and disadvantages. You should choose the one that is right for your business based on your needs and budget.
