mm/s depending on the injection unit) as well as fast clamping movements. The HPS barrier screw for polyolefins allows for particularly fast melting and high shot weights due to a high L/D ratio of 26. The HPS barrier screws deliver a plasticising performance up to 40% higher than the conventional high-perfor- mance screws from KraussMaffei. The company adds that digital services control and monitor the entire manufacturing process of the IML buckets. The APC Plus machine function ensures
ingly popular.” The packaging sector in China is a stable market experiencing constant growth and evolution. “Within the Chinese plastics industry, the production of packaging parts is an important segment with highly specific needs,” says Hell. There were presentations by Engel and its partner companies Pass Card, Wetec, Borouge and Ver- straete, as well as long-standing customer Menshen. Live demonstrations showed how a two-compart- ment yoghurt cup with IML decoration from Ver- straete can be produced economically and efficiently on an all-electric E-mac 180 injection moulding machine. Pass Card’s two-cavity hot runner precision mould and Wetec’s high-speed automation were both the work of Taiwan-based companies and the product of European-Asian cooperation. In a second live demonstration, Engel showcased closures production on a tie-bar-less Victory machine, showing how the barrier-free clamping unit ensures particularly efficient production processes. KraussMaffei is launching the GX 1100 for
larger packaging and logistics applications at K2019. The new model extends the clamping force range of the GX series upwards, with 4,000–11,000 kN now available. “With the new clamping force size of 11,000 kN, we are expanding the range of our successful GX series with a specific target. We see great opportunities particularly in the areas of packaging and logistics,” says Hans-Ulrich Golz, President of the Injection Molding Machinery segment of KraussMaffei. The most recent member of the GX series has the space-saving two-platen design, the GearX and GuideX clamping elements, the modular configuration and a wide variety of equipment options, for example the particularly energy-saving BluePower servo drive. At K2019, the GX 1100-12000 will demonstrate
production of polypropylene buckets with a capacity of 20l each, injected in two cavities and decorated by IML. The shot weight is about 1.5kg with a cycle time of just 14s. The available speed option ensures fast injection speeds (up to 700

extreme consistency in component weight and thus high product quality by controlling the changeover point from injection pressure to holding pressure, as well as the holding pressure level, from shot to shot. Additionally, the dwell time of the polypropylene in the plasticising unit is monitored for the first time, which ensures a high material quality. KraussMaffei and Netstal are combining their
expertise in injection moulding machinery under the new KraussMaffei umbrella brand. With the common portfolio, the company wants to present itself even more effectively, firstly in the medical technology and packaging industries. “Under the single, strong KraussMaffei brand, we
are combining our injection moulding expertise from all application areas. We will be pushing ahead the world of injection moulding more than ever, in keeping with our new, shared motto, ‘Pioneering Plastics’,” says Golz. “The medical technology and packaging industries are the first and foremost common target. The familiar machine series (PX, CX, GX, MX from KraussMaffei and Elion, Elios, PET-Line from Netstal) and the production locations will remain as they are. The new sales organisation is arranged by economic regions so that each custom- er will have only one contact, who will provide comprehensive support. Regional subsidiaries and trade partners create more proximity to customers
