KraussMaffei is presenting its new all-electric PX series for the first time at Chinaplas in Guangzhou (May 16-19, 2017, Hall 15, Booth J 41). Two selected production lines at the KraussMaffei booth demonstrate the unique combination of maximum precision and flexibility in an all-electric injection moulding machine.

All machines are also equipped with the advanced APC plus function, which provides extreme weight consistency of parts and maximum process reliability. KraussMaffei will provide an additional highlight by presenting its new generation of small LRX linear robots for the first time.

The new PX – the all-electric benchmark

The new KraussMaffei PX series is now setting new standards for all-electric injection moulding machines in China. “The new PX series features an unprecedented combination of the advantages of an all-electric injection moulding machine with maximum modularity. Our customers benefit from high precision, productivity and flexibility in all production phases,” states Jörg Wittgrebe, Vice President Sales at KraussMaffei in China.

The selection includes enlarged platens, faster injection speeds and even the option for operation using food-grade NSF H1 lubricants. The wide selection of clamping unit and injection unit combinations is a unique feature on the global market and offers plastics processors in China maximum flexibility. “We see plenty of potential for the new PX series in the 3C industry (computer, communication and consumer electronics), the connector industry, packaging for pharmaceutical and cosmetic products, automotive applications and medical technology,” Wittgrebe adds.

For clean room compatible applications in medical technology, the PX features encapsulated drive units and ejectors and a closed lubricant circuit. In continuous operation, the PX features an ergonomically favourable working height of 130 cm, which remains the same for all clamping forces, ensuring perfect accessibility of the mould and nozzle for setup or during production.

PX 50-180 SilcoSet – high precision in silicone processing

The primary requirements for medical technology applications include high precision, process reliability and compliance with cleanrooms. At Chinaplas, KraussMaffei is presenting a PX 50-180 SilcoSet for the manufacture of liquid silicone rubber (LSR) nasal ventilation units for babies.

The modular concept of the new PX series is particularly useful in processing complex material. The compact design provides plenty of room for demoulding and peripherals, as well as easy accessibility. The automation system with a six-axis robot ensures accurate demoulding of the parts, which are then unloaded and placed in storage compartments.

Reliably process LSR with APC plus

KraussMaffei’s new APC plus function takes on a particularly important task in this application. It compensates for the batch fluctuations commonly encountered when processing LSR. “LSR processing is especially demanding.

The consistency varies from water to honey, and demands absolute platen parallelism to ensure that the mould closes extremely tightly and an injection moulding process that is matured to the finest detail,” states Wittgrebe.

As the process progresses, APC plus monitors the viscosity of the material and corrects the filling volume even in the shot. The process as a whole is made even more precise; the part weight remains constant. APC plus is even able to compensate for any potential preliminary cross-linking of the silicone.

KraussMaffei’s intelligent APC machine function is ideal for all hydraulic and KraussMaffei all-electric injection moulding machines. In addition to processing thermoplastics, multi-component injection moulding or processing silicone, APC plus can also be used for special applications such as thin-walled parts or cascade injection moulding. APC is also ideal for use with recycled materials. More than 1500 APC applications on the market mean that injection moulding is generally more stable and precise.

PX 160-540 with inductive DMH – as stylish as film, but more efficient

New surface effects with precision structures and a hologram appearance are created on a PX 160-540 with inductive DMH technology (dynamic mould heating) that operates with a RocTool at the KraussMaffei booth. The components with the premium quality surfaces are created in a one-shot process, without any additional effort or money whatsoever invested in film decoration or painting. As a result, additional in-mould decoration steps such as preforming, punching and feeding have been omitted.

KraussMaffei is presenting two different design variants at Chinaplas using a finisher as an example. The PX 160-540 produces components with surfaces in a high-gloss finish using structure effects and a hologram structure.
