“Green” prospects at Chinese show This year ’s edition of Chinaplas, to be held in Guangzhou, China, from 17-20 May, is going green – not literally, but with a focus on the environment. Besides an “eco-friendly plastics conference”, the organiser Adsale will showcase a statue made from 3,000 recycled bottles, to set a new record in the Guinness Book of World Records. The exhibition will have 2,200 exhibitors over 180,000 sq m, with exhibitors also taking up the green theme in their machinery and materials showcases. 720H with a 2100 size injection unit, featuring a highspeed, thinwall packaging application. The machine i s c h a r a c t e r i s e d b y h i g h p ro d u c t i v i t y, s h o r t c y c l e times and up to 40% energy savings due to the toggle clamping unit and servo-electric dosage drive. The Hidrive series currently comprises six machine sizes ranging from 60-500 tonnes. The servo-electric clamping units originate from the electric Allrounder A series and are complemented b y h y d r a u l i c i n j e c t i o n u n i t s f ro m t h e A l l ro u n d e r S with electro-mechanical dosage drive and positionr e g u l a t e d s c r e w. P e r f o r m a n c e - a d a p t e d h y d r a u l i c accumulator technology completes the package.

Eco-conscious materials US-based PolyOne will showcase its Stat-Tech POMb a s e d f o r m u l a t i o n s t h a t a re c o m b i n e d w i t h c a r b o n nanotube technology. These are targeted at electronic media storage, integrated circuit packaging and semiconductor devices. The new solutions offer consistent electro-static discharge (ESD) performance a n d h i g h p u r i t y w i t h n o t r a d e - o ff s i n m e c h a n i c a l performance, says the company, allowing for higher yields and cycle times. It will also display its OnColor liquid colourant system that combines metering technology with refillable, returnable containers and liquid colourants in a closed-loop system, thereby reducing wastages. Other products include the OnFlex HFFR nonhalogen TPEs for wire and cable and ECCOH SolarT LSFOH compounds, additive and colourants for photovoltaics (PVs). The company says the latter are s o l u t i o n s t h a t m e e t w e a t h e r a b i l i t y a n d re g u l a t o r y re q u i re m e n t s f or PV s such as b ack -sheet laminat es and TUV wire. The plastics industry in China has continuously maintained high-speed growth for the past 30 years and the Chinese market has become the single largest market for PE and PP with 30 million tonnes consumed in 2010. One such company benefiting from this is Borouge, promoting PE and PP pipes for a wide range of applications including cooling water transportation, sea water intakes and outfalls and effluent disposal. Wi t h t h e a d dition of new Bormod homopolymer grades, Borouge also offers solutions for CPP flexible packaging structures that enable up to 30% downgauging, to realise cost savings. A joint venture between the Abu Dhabi National Oil Company (ADNOC) and Austria-based Borealis, the company has a 50,000 tonnes/year compounding plant in Shanghai, with a second plant now planned for in Guangzhou and expected to be supplying 105,000 tonnes/year of compounded resins by 2012.

At the Chinaplas, Arburg’s Allrounder 720 H machine will show a highspeed thinwall application for the packaging sector

The independent axes movement and toggletype clamping unit ensure reduced cycle times, says the company. And the injection unit, featuring a position-regulated screw, hydraulic accumulators and servo-electric drives for mould and dosage, also contributes to reduced cycle times. Arburg’s second exhibit will be the 150 tonne Allrounder 470C Golden Edition, an entry-level h y d r a u l i c m a c h i n e . Wi t h f i x e d c l a m p i n g f o r c e / injection unit combinations, these machines are targeted at technical components, offering a competitive price/performance ratio. Swiss machine maker Netstal will present its 280 tonne hybrid-drive Elion showing a closure application. The 280 tonne model, along with a 220 tonne version, was shown for the first time at the K2010 last year. Thanks to their modular execution,

Energy saving machinery On the machinery side, German injection moulding machine maker Arburg will display an example of its Hidrive hybrid machine series, a 320 tonne Allrounder 1

Catering to LED lighting growth With the LED lighting market expected to grow at 30% over the next few years and exceed a value of US$5 billion in 2012, many machinery makers are catering to the growth and replacement of conventional light s o u rc e s , i n c l u d i n g h i g h - e ff i c i e n c y f l u o re s c e n t a n d HID fixtures. Having shown its 60-tonne insert machine first at K o p l a s i n S o u t h K o re a l a s t y e a r, w h e re i t re c e i v e d encouraging response, Engel will show it again demonstrating an LED application on a 256-cavity mould by South Korean Woosung Hitech, with a 10second cycle.

The four-tiebar 35 E with its cantilevered, two-platen clamping system will be shown with its new swivelout injection unit. This feature reduces changeover times of the plasticising unit. Austrian company Engel’s focus on energy efficiency will hone into its five exhibits including the Duo 5550/700 machine, which will be producing engine covers on a Mecaplast mould. It is equipped with the servo-hydraulic Ecodrive, which comprises a servomotor with fixed displacement, or variable capacity pump, instead of a permanently running asynchronous motor. The machine’s speed is directly linked to the drive speed and when it is not running, for example during the cooling phase, it does not c o n s u m e p o w e r.
