Injection molding machine is a press machine which is used for plastic molding process. Plastic injection molding method nowadays is commonly used to create and recycle thermoplastic materials. Plastic material has manufactured for most tools in the human life. Plastic cups, keyboards, printers, bottles, and many more are home and office appliances which are from plastic or thermoplastic. Unfortunately, waste plastic can not be digested by bacteria. The invention of injection molding machine that in the past was only used for molding the raw materials, is used to recycle the waste plastic nowadays.
There are several brands or well known producer of injection molding machine. The human being need of thermoplastic based equipments and the environmental issue as the mount up plastic garbage force the industrial world to develop injection molding manufacturing. Benchtop injection molding machine is the example of small had operated molding machine or it can be said that it is home injection molding. On the other hand, Mitsubishi and Sumitomo injection molding machine are two brands that usually used for industrial purpose.
Moreover, there are two basic types of injection molding method. They are hot runner mold and cold runner molds. In cold runner mold, there is significant disadvantage of this system. This mold system will waste the plastic. However, the cold runner method is easy in operation and requires basic skill. The injection molding machine with cold runner is very simple. And the last advantage of this method is from economic side that will lead the molding cost cheaper.
In addition, the injection molding machine with hot runner also has advantages and disadvantages. The significant disadvantage of this hot runner is more expensive than cold runner. However, nowadays plastic industry uses hot runner method. Most of the injection molding machine suppliers manufactures injection molding equipments that use this method. The cavity pressure for this method has several variations.
The components of injection molding machine are injection, screw, clamping force, control panel, platen, and many more. An injection molding equipment is differed type is differed to be hydraulic, electric, horizontal, and screw type plunger; single-stage plunger, two-stage plunger. And from its size, the machine is divided into small, medium, and large size. JSW injection molding machine series is believed as one complete injection equipments and providers in size. For further information this article will review two machines bellow.
MMV Series (1450-4400 US Tons)
This injection molding machine is manufactured by Mitsubishi. This is one of the best machines Mitsubishi has. With compact design, this unit does not waste space. This is two-platen type unit with hydro mechanical clamping system. This machine has high injection speed. It has closed-loop control. This control is used for injection speed and hold pressure. It is easily change from low holding pressure to coining applications.
This injection molding machine is one of large size machine. This machine is very suitable for plastic industry. It is also environmental friendly and saves energy. It will be one good benefit to reduce cost in producing the prototype. This machine is easy to use. The injection mold detail and product specification are written in manual book enclosed.
ME II Series (390-500-610-720 Tons)
ME II series is one of Mitsubishi injection molding machine. This machine has several features. The first feature is direct drive motor which is specialized for superior injection performance. It has on board hydraulic power used for nozzle force. It is environmental friendly and consumes less energy than hydraulic machines in the market. It has jet purge for best performance. It has precise injection or clamp control. It has large platen and also ties bars distance. The MAC-VIII controller is available for this unit.
In addition this special injection molding machine is suitable for industry. It is one of large size injection molding equipment. Compared with other machines, this machine has special capability that can reduce 30 percent of dry cycle times. It make this machine has great repeatability.
