Injection Molding Energy-Saving Small Tonnage Machines
Boy Machines' new BOY 55 E and BOY 90 E injection molding machines are designed to save energy with each cycle.
Boy Machines’ new BOY 55 E and BOY 90 E injection molding machines are designed to save energy with each cycle.
Compared to current technology, the “E” series machines reduce energy consumption by more than 50 per cent, savings enabled by a servomotor pump drive. The speed of the motor is only as high as the respective cycle phase requires. At all times, the motor is performing in an optimum, energy-efficient way.
Further advantages of the new drive technology are a 20 per cent reduction of the noise level, as well as improvements in precision and dynamics.
Extensive repeatability measurements showed a maximum deviation in weight of only 0.115 per cent from the average value. Due to the short response and low inertia properties of the servomotor pump drive, the operation of the BOY injection molding machines is more dynamic and agile.
By using this new drive technology, it’s possible to surpass the positive technical features of electro-mechanical machines without acquiring their disadvantages such as investment cost, spare parts cost, wear, and high connected load.
