production and smooth, flawless surfaces. Krauss- Maffei says the GX series machines come with a Speed option, which, synchronised with GuideX (a precision guide with very low resistance even at high mould load), provides extremely fast clamping movements and reduces the cycle time for large opening strokes.
cal highlight among its exhibits was a Boy 80 E hybrid with an electromechanically driven E-Drive injection unit which produced plates designed by Tide Ocean. This Swiss company has partners who collect used plastics (mainly empty PET-bottles) from the world’s oceans, islands and coastal areas. The waste plastics are sorted, washed, shredded and then transported to Switzerland. In a multi- stage process, the material is prepared without additives in a mechanical process for reprocessing. Another Boy exhibit focussed on bio-based
material. A compact production line – consisting of a Boy 35 E, a specially developed LR 5 linear handling system and a protective housing accord- ing to Euromap 78 – demonstrated the automated production of delicatessen trays made of a PLA. The trays are removed from the open mould by the LR 5 and then placed on a conveyor belt. The entire production unit only requires a footprint of less than 4.8 m².
Boy also highlighted its range of compact machines. A Boy XXS, with an 8mm diameter reciprocating plasticising screw, produced a small toothed gear with 0.2 g part weight made of PA 6. An even more compact Boy XS produced sprue- less egg cups made of biologically degradable Fibrolon with wood-fibre optics. �

KraussMaffei has extended the clamping force range of its GX series upwards and the machines are now available from 4,000 kN to 13,000 kN in clamping force. It says the key benefit of the new GX 1300 is that items such as buckets or crates can be moulded in a double cavity on one machine. The compact design of the 2-platen technology also saves installation space. The production of large buckets
requires a large capacity and high stability at the same time, as well as minimum material consumption in

Netstal, the subsidiary of KraussMaffei, has developed a new generation of its PET-Line systems for PET preform production. It is the first Netstal PET system featuring lateral removal and has full compatibility with existing side-entry moulds and after-cooling stations. The new PET-Line has received its world premiere in presentations at Netstal’s showroom in Näfels, Switzerland, and via online presentations. Like its predecessors, the new PET-Line has
reduced energy consumption. It is also equipped with a new genera- tion of aXos controller technology. The first machine in the upgraded range has a clamping force of 4,000 kN and a 6000 injection unit that enables the use of moulds with up to 128 cavities. Netstal says the coming years will see the launch of further models to optimise coverage of all com- mon beverage applications. �

Engel is expanding the E-mac all-electric machine series to include a version with a clamping force of 1,300 kN, which it is showed with other exhibits at its Live E-xperience 2020 online event from 13 to 16 October. In the demonstration, an Engel E-mac 465/130 produces actuators for connector systems of the Han-Quick Lock brand from Harting in a 16-cavity mould.
Engel says the dimensional demands on the
small precision components, which have a great variance in wall thickness despite their very low weight, are high. A very high level of rigidity is required for reliable function, which is achieved by using a PC material with a glass fibre content.
