Plástico Brasil 2017: Arburg for efficient part production

Plástico Brasil 2017: Arburg for efficient part production
Arburg will be presenting cost-effective moulded part production at the Plástico Brasil 2017 in São Paulo (Brazil) from 20 to 24 March 2017. An Allrounder 470 E Golden Electric from the new electric entry-level machine series will produce covers for toothpick dispensers on the Arburg stand (no. F188). A hybrid Allrounder 720 H will demonstrate the cost-effective production of picnic plates.

"In addition to electric machines, fast, production-efficient solutions are of great interest for the packaging industry. We will be showing both at the Plástico Brasil," explains Alfredo Fuentes, who has been at the helm at Arburg Ltda. in Brazil since January 2017. "After two difficult years, we expect to benefit from a positive business environment in 2017. Our 16-strong, highly qualified team at Arburg Brazil offers customers excellent service, expert advice and reliable premium products."

Entry into electric injection moulding production

Arburg added the "Golden Electric" machine series to its range in spring 2016 with an aim to facilitating 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.

This will be demonstrated by Arburg at the Plástico Brasil 2017 with an Allrounder 470 E Golden Electric. This machine has a clamping force of 1,000 kN and size 290 injection unit, and will use an eight-cavity mould from Btomec to produce toothpick dispenser covers made from PP weighing 1.5 grams each.

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 dual 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 standard hydraulic machines, the high efficiency of the servo motors, continuous power adaptation and energy recovery during braking achieve 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.

Automated packaging solution

With a population of more than 200 million inhabitants, Brazil requires new solutions for packaging and products in the food, drinks and cosmetics sectors. Arburg is demonstrating a production-efficient application with a Packaging version of the hybrid Allrounder 720 H. This high-performance machine with a clamping force of 2,900 kN and a size 1300 injection unit will produce 18 gram picnic plates (diameter 150 millimetres) from PS in a cycle time of around 4.5 seconds. Arburg relies on Brazilian partners for this high-volume packaging industry application: the 4-cavity mould is from RK Ferramentaria and the automation for the removal and set-down of the moulded parts comes from OK.

Packaging version of the high performance machine

Arburg supplies Packaging (P) versions of the hybrid and electric high-performance Hidrive and Alldrive series. The efficient high-speed machines provide high productivity for applications in the drinks industry, while at the same time reducing energy consumption, and excel in their precisely matched combination of distance between tie-bars, clamping force and opening stroke. Further highlights include fast, precise, energy-saving mould movements thanks to servo-electric toggle-type clamping units, high plasticising flow rates thanks to barrier screws and servo-electric dosing drives, dynamic position-regulated screws and effective injection volume flows.
