Japanese used injection machine

Types of Japanese Used Injection Machines

Generally, the used injection molding machine is used to make a variety of plastic products such as containers, automotive parts, industrial components, packaging, toys, etc. Here are the three major types of injection molding machines:

• Plasma Injection Molding: The first one on the list is the plasma injection molding. This type of injection molding creates an object that is passive by using the plasma or ionized gas to emit energy or heat to the material. This heat will melt and mold the material into the desired shape and form through the injection of the material into the cavity of the mold. The benefits of plasma injection molding are the ability to control temperature. It also allows the use of different materials and gives precise molding. Also, the energy used in plasma injection molding is efficient and makes it eco-friendly. Additionally, this kind of injection molding produces high-quality products that require less work or processing afterward.
• Direct-Drive Injection Molding Machines: The second one is a molding machine that uses mechanical motors to directly drive the injection process. The motor then drives the screw that is used to feed, melt, and inject the materials into the molds. The use of direct-drive injection molding machines allows the motor to have a direct connection or drive to the screw that is feeding the material. This gives more accurate control and a better-response injection of the material into the mold. With this technology, the machine can quickly and precisely inject different types of materials, including those that require high pressure or speed. It makes the products smooth and perfect and makes the production process faster and better.
• Screw Injection Molding Machines: The last one is the most common kind of injection molding that uses a feeding screw to melt and inject the materials into the molds. The feeding screw helps the materials to be melted evenly before injecting the material into the mold cavity. With the help of its design, the injection process becomes more efficient and uniform, resulting in the production of high-quality plastic parts. The screw injection molding machines are typically energy efficient and used for making a large number of products that are consistent in quality. This type of injection molding is suitable for all kinds of industries such as automotive, medical, consumer goods, and packaging, to name a few.
