The advantages of utilising multi-component electric injection moulding system has always been recognised especially in areas that demand precision and optimised performance.
Arburg has launched a new series for production-efficient multi-component injection moulding: the Allrounder More, with its particularly flexible configuration, can now be perfectly adapted to specific customer and market requirements. The machines offer increased space for larger moulds, greater modularity during assembly, as well as numerous optimised features for greater ease of use and simple maintenance. The machine takes centre stage at Arburg’s exhibit during the Fakuma 2021.
“Multi-component injection moulding is a very significant and very demanding process. As a pioneer in this sector, we have more than 60 years of technical applications-based expertise. Our ultra-modern range of machines has been developed upon this foundation”, explains Gerhard Böhm, Managing Director Sales and Service at Arburg. The new Allrounder More, presented at Fakuma, covers requirements down to the smallest of details. The first machines will be available to order from October 2021.
Electric clamping and added details
All Allrounder More machines are equipped as standard with a highly dynamic electric toggle-type clamping unit with energy-efficient liquid-cooled servo motors. At series start, the machines have two electric injection units and a clamping force of either 1,600 or 2,000 kN, as required. In future, it will be possible to select injection positions using modules. At series start, one horizontal and one vertical injection unit (V-position) will be available as standard. Horizontal L-shaped (L-position), parallel vertical or parallel horizontal (P-position), and angular (W-position) injection units will additionally be available as options. This will enable all common two-component applications to be realised.
The new machine also offers plenty of free space for mould and ejector. This is because Allrounder More machines provide significantly more space for moulds, rotary units, media connections and a usable ejector stroke. The tie-bars have been extended by 200 millimetres as standard and the moving mould mounting platen has also been enlarged by 200 millimetres. The distance between tie-bars is 570 x 570 millimetres, and the maximum platen daylight 1,200 millimetres. The sliding guard has also been widened by 400 millimetres. Together, all these features facilitate accessibility to the mould area.
Special emphasis has been placed on ease of maintenance and use. Among such features are plug-in media couplings for electrics, water and hydraulics. The cylinder module can be changed in a few easy steps. The vertical injection unit can be conveniently positioned on a support frame, placed on the ground and transported separately from the machine if required.
The material is fed outside the mould area so it cannot be contaminated by granules. Hose guides optimise hose routing and prevent possible chafing marks.
With its numerous improvements to details and modular design, the new Allrounder More series meets all the requirements of a modern multi-component machine. It offers customers from a wide range of industries added flexibility for precision configuration and greater efficiency in the production of high-quality plastic parts made from different materials and colours.
Digitalisation and sustainability
Arburg is focusing on "The best of both worlds": "arburgXworld" and "arburgGREENworld" at its Fakuma presence, which intends to provide visitors with everything there is to know about digital, sustainable and production-efficient plastics processing. Arburg puts a great deal of know-how into its customer portal "arburgXworld" and the development of new digital services and features that bring real added value, such as the "AnalyticsCenter" for process analysis. In future it will also be possible to integrate machines and peripheral devices from other manufacturers into the central platform.
The sustainable production of plastic parts and their return into the recyclable materials cycle (Circular Economy) is illustrated by Arburg through innovative application examples. These include separation by type using a digital watermark ("HolyGrail2.0" and "CurveCode") during production of IML and espresso cups. A real eye-catcher are "green" sunglasses made of bio-based PA12 and produced on a sophisticated turnkey system.
Aside from the Allrounder More series that will premiere at the exhibition, other Arburg highlights are the planetary roller screw drives developed and produced in Lossburg and the trendsetting Gestica control system. A total of nine machine exhibits will demonstrate innovate applications and processes at the trade fair stand. On view will be the efficient production of IML cups for the packaging sector, of blood tubes and 2k fluid housings for the medical sector, as well as the injection moulding of LSR face masks and the industrial additive processing of LSR materials and original plastic granules.
