From Tabletop to Poffertjes
In a total of 14 exhibits (eight at the own booth), Dr. Boy GmbH & Co. KG of Neustadt-Fernthal, Germany, presents its competence as a machine manufacturer for nearly all capacities and series, starting with the compact Boy XXS and Boy XS, going on to encapsulating and additive injection machines, and culminating in the Boy 100.
The new Boy XXS tabletop machine (63 kN clamping force) produces small toy figures from foamed PP. Here the machine’s mold changing system enables short tooling times, an important advantage for small series and prototyping.
The processing of PEEK material on the Boy XS (100 kN clamping force) and the use of a novel mold concept on a Boy 35 E are further applications being demonstrated. The energy efficient approach of Technologiebüro Hein works with partial temperature control of the mold – in the shown process of a 3D printed metal mold insert.
In under 45 s, a Boy 35 E VV will mold a Poffertjes silicone baking pan. An Igus robot (Type: Robolink 5) removes the molded silicon form from the mold and lays it on a conveyor belt for cooling.
In combination with an additional Boy 2C S injection unit, a Boy 60 E produces a two-component bottle spout. The Boy 60 molds the transparent part of the spout from NAS, then the Boy 2C S encapsulates the bottle spout with two TPE sealing lips. The finished part is subsequently removed from the mold by the Boy LR 5 removal handler and set down on a conveyor belt.
Above and beyond that, Dr. Boy as producer of automated injection molding machines in the clamping force range up to 1000 kN is emphasizing a fast running application. Dosing caps for insulin pens are produced on a Boy 100 E (1000 kN clamping force) in a large-volume 48-fold mold. At the start of the injection molding cycle, dual servo pumps installed in the machine enable nozzle system pressure and high pressure to be built up in parallel. At the end of cycle, both, mold opening and closing functions can be performed in parallel by the dual servo pumps.
