Dr. Boy & Co. GmbH, the specialist in small-tonnage injection molding machines is getting bigger — in press sizes, that is.
Fakuma 2018 will mark the world premiere of Boy's largest press to date, the Boy 125 E, with a clamping force of 125 metric tons. Fakuma visitors will be able to see it at Booth 7101, Hall A7.
What's the motivation for a bigger Boy? According to company officials, in recent years, there has been a lot of innovation in multi-component injection units. Other Boy models are already used with many third-party machines, the company said.
Multicomponent molds — some of which have been designed to handle up to six-injection units, Boy said — require larger machines. They have rotary platens.
At Fakuma, the 125 E will mold two-component cups by first injection molding the cup body, then partially overmolding them in the same mold. The gripper head of a Boy LR5 robot will reposition the pre-molded cups in the mold, remove the finished two-component parts and place them on a conveyor belt in the protective housing of the LR 5 automation cell.
Boy's 125 E has a clear width of 470 millimeters (18 inches) between the tie bars instead of the previous distance of 430 mm. The maximum platen distance has been extended to 825 mm (32.5 inches) as standard, to accept rotary platens.
The Boy 125 E will be integrated into full production next spring.
Boy will show other new products involving that LR 5 removal handling at Fakuma, with a telescopic version, shown on a Boy 35 E. The compact linear handling system is especially good for production sites with low ceilings.
Boy will show three LR 5s at its booth.
