Types Of Used Injection Molding Machines

Used Injection Molding Machines

When there a need to produce parts in large volume, injection molding is the answer to the manufacturing process. Injection molding is used in mass production processes where the product is created several times in succession. Injection molding is achieved using an injection molding machine. An injection molding machine also known as Press is an electronic device in which melted granules are put in casts to design products of various shapes and sizes. There are different types of injection molding machines classified primarily by the type of driving systems they use. The system can be mechanical, electric, hydraulic, or hybrid. Below are the types of used injection molding machines.

The first type of used injection molding machine is the hydraulic injection molding machine. These machines have been the only option available to the molders until the first electric injection molding machine was introduced. Hydraulic presses use the hydraulic principle as the mode of operation. The high clamping force generated by these machines makes them essential in big part production. Although not nearly as precise compared to other machines, hydraulic injection molding machines are the predominant type in most parts of the world.

The second type of used injection molding machine is the mechanical injection molding machine. These machines use the toggle system for generating tonnage on the clamp side of the machine. Tonnage is crucial of all used injection molding machines as it prevents the clamp side of the machine from opening due to pressure generated by injection. In case the tool half opens, flashes will be created on the plastic product.

The last type of used injection molding machine is the electric injection molding machine. They are also known as the electric machine technology and was first introduced in 1983 by Nissei Plastic Industrial Co. These machines use electricity for their operation. Electric presses are quieter, faster, and have a higher accuracy even though expensive as compared to the other used injection molding machines. These machines reduce the cost of operation and also solve some of the environmental concerns surrounding the hydraulic injection molding machine.
