Two injection moulding machines at Plast Milan: a small giant and a big dwarf

From 5th to 8th September 2023, the internationally important plastics trade fair Plast Milan is going to open its doors. The German machine manufacturer BOY will present two of its injection moulding machines on the booth of its Italian representative ST.A.TE. Technologies srl in hall 24 / booth B121: The BOY XS E and the BOY 100 E hybrid – the smallest and one of the largest models in BOY’s product portfolio.

 A BOY 100 E hybrid produces Polypropylene (PP) gift boxes in combination with the BOY-Handling LR 5. The “hybrid” in the machine name characterizes the option servo-electric injection unit. In this specially developed injection unit with the international size SP170, the injection and metering movements are driven electro-mechanically via two servo motors. The rotational and axial movements of the injection unit are performed by two servomotors, which are completely detached from the machine hydraulics.

The independent operation of the injection unit is particularly advantageous for short cycle times and high metering volumes. The BOY 100 E hybrid with a clamping force of 1000 kN and a compact footprint of 4 m² demonstrates the visitors to Plast Milan how space-saving the BOY LR 5 linear handling system can be positioned on the injection moulding machine. In combination with the required protective housing, BOY will present a fully automated production unit on a footprint of barely 9 m².

On the new BOY XS E, baby bottle nipples are made of silicone. The new injection moulding machine – designated successor of the highly successful BOY XS – has now the proven servo drive of the BOY E series. Energy efficiency, high dynamics and extremely smooth running characterize the compact injection moulding machine with 100 kN clamping force. The BOY XS E demonstrates its strengths mainly in micro injection moulding and sprueless production in single-cavity moulding. The new BOY machine model is optionally available with two different clamping platen configurations. In the standard version for conventional mould sizes up to 160 mm (diagonally up to 205 mm clear width between the tie bars) as well as with a special mould holder 75 x 75 mm for micro moulds of many well-known standard manufacturers. Even in the standard version, the BOY XS E offers the advantage of an injection unit that can be adjusted in height by up to 25 mm, thus enabling decentralised gating.
