Thinner, stronger packaging films
Hall 10.2, booth A41
ExxonMobil Chemical deliver solutions for the entire value chain, including opportunities to improve performance, reduce total costs and help meet the growing trends for sustainable solutions. Metallocene polyethylene (mPE) and Exceed mPE resins and Vistamaxx propylene-based elastomer (PBE) are used for a broad range of flexible packaging applications. They may allow converters to develop downgauged flexible films with good mechanical properties and sealing strength which can then enhance package integrity. This makes these brands suitable for a broad range of film applications in consumer and retail packaging, industrial packaging and agricultural films.
Adding Vistamaxx PBE to an existing stretch hood film formulation being used at an ExxonMobil Chemical plant in Belgium is said to deliver up to 16% reduction in material use. Tests undertaken by ESTL of Belgium indicate that 25kg sacks of polymer pellets are kept secure and stable on the pallet. The modified three-layer film structure comprises 100% Exceed mPE resin in the outer layers and 15% Vistamaxx PBE and 85% Nexxstar EVA copolymer resin in the core. The Exceed mPE resin-based skin layers are said to deliver toughness, improved resistance to hole formation and tear propagation and good optical properties. Nexxstar EVA copolymer resins provide high holding force and stretch capability. The addition of Vistamaxx PBE in the core layer allows elastic recovery to be enhanced. The film met the application’s stretch ratio target of 55% and was thinner than the original film, having been downgauged from 100 to 90µm.

Flame retardant, scratch resistance, co-adhesion with nylon
Kraiburg TPE will be introducing three new products within the Asia-Pacific region. These products are characterised by good properties such as flame retardant, scratch resistance, CO/NY (co-adhesion with nylon).
The FR/AP series is a newly developed halogen-free intumescent flame retardant based on phosphorus and nitrogen synergism, and the flame retardant effect is achieved through intumescence. When exposed to flames, the thermoplastic material will foam. When this happens, the carbon foam layer will protect the polymer with its heat insulating effect, limiting oxygen access to prevent the thermoplastics from dripping. The overall results of this HFFR compound showed good flame retardant consistency and processability. The FR/AP series is also said to offer a new dimension of colourability especially for the manufacture of electrical and electronic components, injection moulding parts for construction areas such as switchboxes, cable distributors as well as indoor applications, including automotive, ship, aircraft and many other applications.
The new SCR series is said to offer good scratch resistance, such as mechanical stress with the scratching motion of a sharp edge or rounded object. Besides scratch-proof feature, the SCR series is said to offer a good surface finish that attracts little dust. According to the company, it has also demonstrated excellent mechanical properties with equally good PP adhesion. It has colourable natural compounds that allow product designers flexibility when designing specialised applications like automotive indoor parts, anti-slip mats, soft touch push buttons, switches, handles, and more. Other applications for the SCR series include the manufacture of products for the building industry such as screwdriver, toolbox and so forth. For the consumer industry, it includes everyday products that demand superb scratch resistance like mobile phone casing parts, covers, ski and hiking sticks, etc.
The new CO/NY series is said to feature good nylon/PA bonding with TPE compound, even with softer compounds, and to have good adhesion in co-injection and insert moulding. It offers product designers flexibility and versatility as the CO/NY series’ natural compounds make it easy to colour, has tactile surface with a soft touch and good flow characteristics. Its wide hardness ranges from 40-90 Shore A and it is currently UL 94 HB listed (pending).
The CO/NY offers a wide range of applications in different industries, including the manufacture of handles for hand tools, power tools, over-moulded housings for the building/construction industry, electrical and electronic components, seals and diverse design and functional elements for the consumer industry and durable components like air inlet piping, cowl, stop button, door sill and more for the automotive industry.
Optimised IV tube manufacturing
Hall 1.1, booth M51
Maillefer has announced new features for its PML extrusion lines for the production of medical intravenous PVC (IV) tube. The advantages are increased speed and product optimisation that are carried over to the manufacturing processes located downstream.
A smooth and glossy IV tube surface has the undesirable effect of surface tackiness, which is accentuated when conditioned on coils. The winding and later unwinding operations are slowed as a result. Maillefer has added features to its extrusion technology that result in a tube surface with lower adherence. The positive gain is felt on the extrusion line speeds and on the following operation being sourced with coiled tube.
Three conditioning possibilities are available from the line: a full length coil, a multiple length coil and individual cut lengths. The classic method calls for tubes of long length wound into coils through use of a fully automatic dual coiler at the end of the extrusion line. The delivered coil then needs to be unwound and cut into individual lengths during the assembly step. Another solution is to deliver short lengths produced directly on the extrusion line with an integrated cutting machine. The third solution innovates by combining both methods. Here, short tubes are prepared online, while maintaining a tractable tube for coiling. The advantage is having easy-to-handle coils while delivering tube that is easily separable.
Maillefer’s PML 032 line is geared for a speed of 300m/min. The line is said to operate at constant speeds, even during coil transfers. Available control features include process monitoring, data logging, event alarms, recipe storage, scheduler, report generator and video monitoring. According to Maillefer, the entire line is designed and built to the strict requirements of the medical device industry.
Premiere of all-electric injection moulding machine in China
Hall 4.1, booth J4
Innovative system solutions for more efficient processes and a greater competitive advantage are the focus of the Engel trade fair booth. Live on show: the new all-electric Engel e-mac injection moulding machine, demonstrating its capability in the manufacturing of electronic mass products. At Chinaplas 2013, the new model series is celebrating its first airing in China.
An Engel e-mac 50/50 will be producing holders for semiconductor chips made of polyetherimide, an application that poses an extremely tough challenge in terms of the injection moulding machine’s precision. The holders measre 26 by 23mm, but the critical factor above all others is the thin wall thickness of just 0.65mm and the mesh structure to be created with an inner edge length of 0.42mm. Despite these exacting requirements and the hard-to-handle raw material, the e-mac achieves a cycle time of just 19s in this application. With an acceleration of over 20m/s2, according to Engel, the injection axis of the Engel e-mac is now the world’s fastest of its kind. Additionally, the synchronous movements of the drive axes ensure fast cycle times.
Due to its compact footprint, the Engel e-mac saves shop floor space and is frugal in its use of resources. From injecting and metering to mould and ejector movements, all drives in theEngel e-mac are servo-electric. They are operated by a modern axis system solution involving a stabilised intermediate circuit. The braking energy is recovered and fed back into the grid. The Engel e-mac series has four machine sizes with clamping forces of 50, 75, 100 and 180t. Equipped with the proven CC 200 control unit, the Engel e-mac offers complete modularity and automation technology integration capability. While the Engel e-motion machines have established themselves in medical technology and in fast running applications in the packaging industry, the Engel e-mac is said to be an economical alternative for applications in technical moulding and the electronics industry.

Optimised modules and clearance classes are available to meet specific application requirements, depending on viscosity and throughput. Maag’s Extrex pumps are designed to withstand differential pressure of up to 400bar and discharge pressure of up to 500bar.
Compact system for laser plastic welding
Hall 5.1, booth L 27
LPKF launches the volume-production version of the LPKF InlineWeld 6200. This system enables strong reliable laser welds to be created even when only a small footprint is available for the equipment. The system can be used integrated within the client’s own production set-up.
The LPKF InlineWeld 6200 succeeds the tried-and-tested LPKF InlineWeld 6600 (formerly known as LQ-Integration), and requires even less space. It consists of two components: the control unit measures a mere 40 x 53 x 60cm (w x h x d). This contains the control electronics and the laser source, all housed within a maintenance-friendly 19” rack system. The control unit can be positioned outside of the actual working area independent of the head module which does the welding, for instance, either above or below the component handling equipment. The control has a field bus interface to communicate with master computers and transfer the tracking data.
The head module is permanently connected to the control unit and consists of a laser scanner and the clamping tool. Thanks to its small footprint of only 330 x 370mm it can be positioned within even the most restricted spaces.
The LPKF InlineWeld 6200 is equipped with a tool that is also designed for laser protection (laser class 1). The tool holder holds the components to be welded. The maximum welding contour dimensions are 100 x 100mm. The upper drawer is used for the fast, tool-free swap-ping of the clamping device.
The flexible welding unit can be integrated on rotary tables or conveyor belt systems within fully-automatic production systems. It can also be used economically and productively in partially automatic production layouts, for example, with manually-fed drawers.
The laser welding system is equipped with laser sources with outputs of up to 120W – the power required depends on the intended components, the production set-up and the specified cycle times. The glass protecting the optics is said to be easily cleaned because it is also located in an easily accessible drawer. Every LPKF laser welding system is supplied complete with efficient software to define the welding contours.
