All-electric KraussMaffei PX series sets a course for China

 |  Subj: Press-releses

Premiere in China: 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 molding 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 molding machines in China. "The new PX series features an unprecedented combination of the advantages of an all-electric injection molding 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 favorable working height of 130 cm, which remains the same for all clamping forces, ensuring perfect accessibility of the mold 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 demolding and peripherals, as well as easy accessibility. The automation system with a six-axis robot ensures accurate demolding 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 mold closes extremely tightly and an injection molding 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 molding machines. In addition to processing thermoplastics, multi-component injection molding or processing silicone, APC plus can also be used for special applications such as thin-walled parts or cascade injection molding. APC is also ideal for use with recycled materials. More than 1500 APC applications on the market mean that injection molding 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 mold 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-mold 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.

Premiere of new small linear robots
The new LRX 50 ensures reliable component demolding. It is part of the new generation of small KraussMaffei linear robots that feature a new, progressive design with a decentralized control cabinet concept and freestanding x-axis. They offer high flexibility in processes such as simple retrofitting of sensors or expansion of media circuits. Rack-and-pinion drives used in place of toothed belts offer fast, high-precision movements in all axes. A revised thermal and protection concept for the electronic components with an IP54 protection rating rounds off the new concept and provides high levels of availability and dependability.

The removal gripper produced through the 3D printing process is especially lightweight and can be manufactured quickly and easily while ensuring weight optimization. In addition, the lightweight gripper can be perfectly adapted to the 3D contour of the component. Simple integration of cavities offers additional advantages. In this way, the hose connections can be simplified, for example, producing a compact gripper without protruding edges. The use of cavities for additional rigidity is also possible.In addition to Roctool, other partners at KraussMaffei trade show exhibits include Wacker Chemicals, Piovan, Elmet and Covestro.
