In an unprecedented move, for the first time a new machine from Arburg is celebrating its world premiere not in Germany, but on the international stage. The new Allrounder 720 E Golden Electric with a clamping force of 310 tons (2,800 kN) extends the product range of the electric series of the same name upwards and is the highlight at NPE2024 during May 6 through May 10 in Orlando, Florida. Streamlined in terms of installation area and price — this summarizes its main advantages. The new injection molding machine continues to stand out for its electric precision and process stability and offers high component quality with low investment costs and short delivery times.

Slim in design and price

Arburg has optimized the design so that the new Allrounder 720 E Golden Electric, with a width of just 6 feet (1,848 mm), has a significantly reduced installation area compared to other machines in its class. This has been achieved, for example, with a new safety door featuring recessed handles. At the same time, the stroke has been widened to 55.1 inch (1,400 mm) to gain better access to the ejector area.

Due to its smaller installation area, the new Allrounder fits into existing production grids and lines. Thanks to the new design, more machines can be set up in injection molding production, resulting in an increased output per square foot.

Reliable, stable machine technology

The Allrounder 720 E Golden Electric features high-quality machine technology to ensure stable and reliable plastic parts production. This includes a toggle-type clamping unit and direct drives from the subsidiary AMK. With an electric mold height adjustment system, mold installation heights of up to 31.5 inch (800 mm) are possible. The drive components are optimized for a clamping force of 310 tons (2,800 kN). The proven high-quality Arburg plasticizing with the "aXw Control ScrewPilot" ensures reproducible injection and excellent molded part quality. Optimized mold venting with two-stage mold locking also plays a part in this.

For convenient maintenance, the new electric Allrounder has the same easily accessible control cabinet concept as the new hybrid machines. Lubrication unit and optional pneumatics are located on the operating side. The parts chute in the machine base has been widened to 33.5 inch (850 mm), making it easily accessible.

Attractive price/performance ratio

The electric machine is not limited to a specific product and has short delivery times, which is particularly advantageous when it comes to urgent replacement purchases and capacity expansions. It is equipped with the Selogica ND control system as standard. If required, additional options and functions such as core pulls and heating and cooling circuits can be easily integrated and programmed. As a result, the new electric injection molding machine produces a wide range of plastic parts flexibly, efficiently and reliably.

Flexible automation and application

The Allrounder 720 E Golden Electric can be automated with all robotic systems from Arburg — from simple sprue pickers to Multilift linear robotic systems and six-axis robots. The exhibit is equipped with a Multilift V 30. The new 'golden' electric machine is interesting for almost every industry. It is particularly suitable for less complex products and cycle times of around 15 seconds or more. Typical areas of application include dimensionally stable housings for electromobility, thick-walled closures for household goods, precision components for medical technology and the construction, leisure and technical injection molding sectors.

At NPE 2024, the Allrounder 720 E Golden Electric with a clamping force of 310 tons (2,800 kN) and a size 800 injection unit will be producing razor covers from PP. A 24-cavity mold from Hack will be used. The cycle time is around 8.5 seconds and the molded part weighs 0,04 ounces (1,2 grams).
