  • Germany-headquartered KRAIBURG TPE, which recently opened a new sales office in Seoul, South Korea, will showcase its new VS/AD/HM series as part of the Thermolast K product line.

  • The introduction to the Chinese market is in response to an increasing demand for high-tech materials used in the production of consumer electronics and high-end lifestyle products, such as smartphone cases, headphones, remote controls or VR headsets.

  • Also on show will be a portfolio of premium TPE compounds and custom-engineered solutions for consumer, industry, automotive and medical applications. Features include a smooth silky surface with chemical resistance against sebum and abrasion and scratch resistance. The compounds are easy to colour and have improved adhesion performance and mechanical properties.

  • German machinery maker Arburg will display two automated hydraulic and electric Allrounders and the Freeformer for industrial additive manufacturing. These will produce smartphone covers from LSR, medical technology connectors and spare parts for the aerospace industry. Further innovative Allrounder applications featuring medical technology and LSR processing are presented by Hekuma and Mehow.

  • A 60-tonne Allrounder 370 E Golden Electric will demonstrate precision production of medical technology parts, using a two-cavity mould from Wellmei to produce Y connectors for intravenous drip therapy in a cycle time of 18 seconds. The finished PC moulded parts are removed and set down by a Multilift Select linear robotic system.

  • At the Hekuma stand, a hybrid Allrounder 520 H will use a 64-cavity mould to produce pipette tips with a capacity of 200 micro-litres from PP in a cycle time of only around 4.8 seconds. The quality control and robotic systems are supplied by Hekuma. Weighing 0.35 g each, the moulded parts are set down in trays of 96 units.

  • For LSR, a 100-tonne hydraulic Allrounder 420 C Golden Edition will produce 21 g-weight covers for the iPhone 6 in a cycle time of around 25 seconds.The mould is provided by Prover, while the LSR dosing unit comes from 2 KM. Mehow is also presenting an LSR application with a turnkey system built around a hydraulic two-component Allrounder 470 S producing wine bottle closures using a hard/soft combination (PC/LSR). Handling is performed by a six-axis robot in this case.

  • A Freeformer will produce a spare part from PC for the aerospace industry. Using 3D CAD data as a basis, the parts are produced from inexpensive qualified plastic granulates using Arburg Plastic Freeforming (APF). The Freeformer is equipped with two discharge units as standard. This enables it to process an additional component in order, for eg, to manufacture a part in different colours, with special tactile qualities or as a hard/soft combination. Alternatively, it can be used to build structures from a water-soluble support material, enabling complex part geometries to be realised.

  • Taiwan’s FCS will launch its horizontal rotary table two-component machine and servopower-saving multi-component machine. The HB-R two-platen twocomponent machine series was developed in 2012 with a clamping force of up to 1,900 tonnes. FCS says this is one of a few huge two-component injection machines in the world. This series combines the two-platen and two-component structure, horizontal rotary table, stack mould, and servo power-saving technology. FCS will be displaying HB-350RV with a Kuka six-axis robot producing two-component parts for a car sunroof application.

  • The horizontal rotary platen decreases issues coming from gravity and inertia, is able to withstand a load of up to 3.6 tonne and complete a cycle within 3 seconds, says FCS. The model is capable of producing single and dual component products, while a 350-tonne machine has the same mould loading capacity as a 1,000 tonne-dual-coloured injection machine.

  • In the dual moulding field, FCS says it has been ahead of the industry to lead the direction of innovation. Moreover, it says that the servopowersaving multi-component machine allows for a mould clamping force of up to 1,900 tonnes; and with closed-loop servo value, the single-cylinder injection structure and accurate rotary positioning clamping, the machine can perform stable actuation and precise positioning, thereby leading to high-response, highprecision and high repeatability.

  • FCS will be showing the 16-cavity FB-280RV model producing a two-component drinking water bucket lid. With the servomotor-controlled rotary table, rotary time is shortened by more than 50%, with a more stable rotary speed switch and more precise positioning. The machine also adopts a high efficiency double servopower system, which is certified as the first grade of national power saving standard (<0.40kw h/kg). Meanwhile, the accurate rotary positioning clamping protects the mould.

  • Due to many application requirements, FCS says it will have a special area to display the applications and introductions of multi-component machines to offer more wide uses for industries such as automotive, construction and aerospace.

  • China-based Wintec, a subsidiary of Austrian machine manufacturer Engel, will be showing its t-win large-scale hydraulic machine and its latest e-win all-electric. All movements performed by the e-win machines are servo-electric. The machines also reduce cycle times through the synchronous Wintec movements of the drive axles and the acceleration of the injection axis, which can be up to 22 m/s².

  • At Chinaplas, a 100-tonne e-win 1000-170 will be used to produce glass fibre-reinforced nylon windscreen wiper adaptors for cars. An Engel e-pic robot will remove the components from the mould and deposit them on a conveyor belt. The robot combines linear movements with a jib arm, saving on space.

  • Germany’s KraussMaffei will present its PX allelectric series, featuring enlarged platens, faster injection speeds and the option for operation using food-grade NSF H1 lubricants. The machines are targeted at China’s 3C industry (computer, communication and consumer electronics), connector industry, packaging for pharmaceutical and cosmetic products, automotive applications and medical technology. For clean room-compatible applications in medical technology, the PX features encapsulated drive units and ejectors and a closed lubricant circuit.

  • At Chinaplas, KraussMaffei will have a PX 50-180 SilcoSet for the manufacture of LSR nasal ventilation units for babies.

  • LSR-nasal
  • With Asia being one of the most important markets for the Wittmann Group, since it has a ten-year old facility in Kunshan for robots, temperature controllers, material loaders and granulators, its subsidiary Wittmann Battenfeld will display three machines from its PowerSeries at Chinaplas.

  • The EcoPower SE 110/350 will present a cleanroom production cell, equipped with a Laminar Flow Box supplied by Max Petek, Germany, to manufacture a closing cap from LDPE in an eightcavity mould.

  • The Combimould SmartPower servo-hydraulic machine, shown for the first time at the K2016 Wittmann-Battenfeld’s-EcoPower in Düsseldorf, will make a drinking cap made of thermoplastic/LSR in an eight-cavity mould supplied by ACH Werkzeugbau, using transfer technology. On a MicroPower 15/10 the company will show an opto-electronic application, with a barrel holder made of POM produced using a mould supplied by Wittner, Austria. This component is a focusing device used mainly in cameras to hold the lenses in place or to focus them.
