Interplastica 2017: Arburg heralds a “golden” electric era

22 January 2017

Arburg launched the “Golden Electric” machine series onto the market in spring 2016 to facilitate the cost-effective entry into electric injection moulding production. Like their successful “Golden Edition” hydraulic counterparts, the new electric machines offer an excellent price/performance ratio thanks to consistent standardisation, e.g. a fixed combination of distance between tie-bars, clamping force and injection unit size.

High-performance, precise, energy efficient
The Allrounder Golden Electric is available in four machine sizes with clamping forces from 600 to 2,000 kN.
The double five-point toggle system ensures fast, high-performance cycles. The play-free spindle drives operate with high precision. The position-regulated screw ensures high moulded part quality.
The new electric machine series also features liquid-cooled motors and servo inverters and offers benefits in terms of energy efficiency, short dry cycle times and high reproducibility. Compared to hydraulic standard machines, the high efficiency of the servo motors, continuous power adaptation and energy recovery during braking provide for energy savings of up to 55 percent. The machines are also easy to maintain thanks to swivelling injection units, plug-in cylinder modules and further improved lubrication and cooling.

Ideally suited to high-quality technical parts
The entry-level electric machines are mainly used in the cost-efficient and reproducible manufacturing of high-quality technical parts. At the Interplastica 2017, Arburg will demonstrate the manufacture of syringe barrels with Luer lock threads for the medical technology sector: An Allrounder 520 E Golden Electric with a clamping force of 1,500 kN and a size 400 injection unit will produce eight moulded parts from PP in a cycle time of approximately ten seconds. The 8-cavity mould from Tim Plastik is equipped with hot runner technology.

Allrounders for the medical sector
In addition to the standard range, Arburg offers special clean room solutions. The modular product range enables Allrounder injection moulding machines and production cells to be very precisely tailored to customer requirements and the application at hand. This includes the high-performance electric Alldrive series, which is optionally available in a clean room version and in a stainless steel version with a clamping unit.
A clean-air module with air ionisation above the clamping unit provides for low-particle air in the working area. Thanks to preliminary and HEPA filters, it ensures a high level of air circulation and neutralises electrically charged moulded parts. Liquid-cooled drives, which are standard at Arburg, also contribute to low-emission production. Moreover, FDA/NSF H1-compliant lubricants are exclusively used.
