Lehmann & Voss’s Luvocom XTF is a new generation of polymers lubricated with a proprietary PTFE formulation. Said to exhibit significantly increased wear resistance, especially at high loads, compared to standard formulations, they open up opportunities in automotive, industrial and oil and gas market applications, as well as high precision machined components via stock shapes. Benefits also include short running-in behaviour and the PTFE remains intact with the polymer during injection moulding. The first compounds in the series are based on PEEK, with other formulations to follow.

Extrusion Machinery • With a rising demand for hygiene products and especially for breathable film, Windmöller & Hölscher (W&H) will show blown and cast film lines. Formerly produced on cast film lines, breathable film output is now shifting towards blown film featuring enhanced properties, less thickness and therefore also material and cost savings. In general, breathable film is produced by embedding small particles of calcium

Gneuss, which has established its Multi Rotation System extruder for processing PET reclaim without pre-drying, will show the SFpvc, the latest addition of screen changers for PVC. It is characterised by the adaptability to match the individual extruder and robust drive system to handle contamination surges. This model has proven itself in recycling of PVC plastic windows.

Injection Moulding Machinery • Arburg will launch its Freeformer for additive manufacturing for the Asian market. It will demonstrate the potential of plastic Freeforming for functional parts as one-off items or in multivariant small-volume batches, manufactured from standard granulate based on 3D CAD data, without a mould. The company says it can achieve far more than a simple 3D printer.

The granulate is first melted in a plasticising cylinder. The second discharge unit can be used to produce multi-component/colour parts. One Freeformer will combine a TPU material with a special supporting material – a first in additive manufacturing. Possible applications include bellows, hoses, sleeves, or flexible parts for robotic grippers. The supporting structures can subsequently be removed in a water bath. Last year, the Freeformer received the internationally renowned Red Dot Award for industrial design, next to top brands such as Apple, Audi and Adidas. Arburg demonstrated the process for the first time at the Fakuma 2014 (Germany) producing an office scissors with individualised lettering.

Arburg will also present the hybrid Allrounder 570H designed for thinwall packaging applications. A 2+2-cavity stack mould is used

Arburg will present a medical technology application, in which prefillable syringe barrels made from COP are manufactured as a substitute for glass

for the IML application, which compared to a conventional four-cavity mould, permits the use of a smaller machine. It will produce four 200 ml margarine tubs in a cycle time of around 3.2 seconds. The automated process is performed by a two-axis robotic system.

It inserts two so-called butterfly labels on both the fixed and moving mould platens and removes the finished parts from the central block.

It will also display an electric Allrounder 470E demonstrating the production of prefillable syringe barrels made of COP (cyclic olefin polymer), which is transparent and has similar barrier properties to glass, but almost unbreakable and more costefficient. In a subsequent step, the syringe barrels can be pre-filled, assembled and packaged ready for use. The Multilift Select robotic system from Arburg is used to remove the barrels.

German Machinery and Technology Other European Machinery • Extrusion machinery manufacturer battenfeld-cincinnati Extrusion Systems has been active in China for 19 years. At Chinaplas, the company will introduce its new management, and the extended turnkey LeanEX extrusion line for pipe diameters up to 400 mm.

In March, Toni Bernards was confirmed as CEO and Bruce Lamont as COO of battenfeld-cincinnati’s Chinese subsidiary. In addition, Bernards will also serve as Head of Global Sourcing for the group.

Bernards explains on the Chinese market: “We have a strong position in the market and an experienced team of engineers and sales people. The market situation is becoming more difficult as overall growth rates in China decrease. However, last year, 75% of customers ordering with us were new customers. This is a good basis.”

Following customer demand in Southeast Asia, South America, Africa, the Middle East and Russia, battenfeld-cincinnati China has extended its basic line solution for PO pipes to four sizes: 63, 160, 250 and 400 mm. The lines are equipped with the LeanEX extruders in one of three sizes: LeanEX 60-30 (output HDPE 350 kg/ hour, PP-R 280 kg/hour), LeanEX 75-30 (output HDPE 500 kg/hour, PP-R 400 kg/hour) and LeanEX 90-30 (output HDPE 800 kg/hour, PP-R 640 kg/hour). LeanEX turnkey lines cater to companies that need a low cost line for small, standard pipe applications. They are offered in a basic package with limited options, a smaller control panel and control system, as well as locally sourced screws, barrels, motor and drive. The pipe heads are from the standard helix series.

The company also recently introduced solEX single-screw and twinEX twin-screw extruders to the local market. These machines are equipped with energyefficient AC motors and, in combination with gravimetric dosing systems, can save up to 3% material in PE pipe extrusion, while consuming about 200 kWh less than the average local extruder when producing 1 tonne of PE pipe. It will show a solEX 60-40-C and a twinEX 93-28-C at Chinaplas.

Meanwhile, for thermoforming sheet extrusion, last year, battenfeld-cincinnati sold the fourth sheet line with high-speed extruder and Multi-Touch roll stack in Asia

to Chinese company Guangdong Huasheng Plastics, Shantou. With a capacity of 1,400 kg/hour, this line replaces four to six of the previously used Chinese lines.

It can produce sheet ranging from 350-2,500 microns in thickness.

MAY 2015

Swiss company Maag will show the new design of its underwater pelletising system, Sphero S, making it ideally suited for masterbatch and recycling applications with medium outputs between 700-3,000 kg/hour.

Improvements include a new frame that allows it to be mounted on a single mobile structure for a reduced footprint. The design of the cutter head facilitates startup, to ensure less agglomeration and production of evenly shaped pellets.

The Baoli line of dry-cut strand pelletisers for the Chinese market are manufactured in Maag-Automatiks's local facility. The series is available in three basic machine sizes with operating widths of 100 mm, 200 mm and 300 mm.

Another highlight will be the extrex series gear pump and filtration system for extrusion, compounding and recycling applications. It generates the required pressure for downstream processing with energy efficiency, while at the same time reducing the burden on the upstream extruder by eliminating pulsations and pressure surges.

Maag’s extrex EA is a localised extrusion pump that is assembled at its facility in Lingang near Shanghai, with key components, such as gears and bearings made in Maag’s European facility. Maag is now extending the EA pump with the sizes extrex 36-EA and 110-EA for an output range of up to 4,200 kg/hour.

Recycling equipment supplier Erema's focus will be on its new Intarema system featuring the core technology Counter Current. The Austrian firm says it has already sold 150 systems worldwide since the launch in 2013.

As the trend is continuing in Asia, too, Erema will present an Intarema 1007 TVEplus system with a melt filter SW4/104 RTF as an exhibit. With an output of 300-350 kg/hour, the system will be shown operating to demonstrate the recycling of heavily printed LDPE materials.
