Arburg’s systems to help AM users

"We have been addressing the subject of Industry 4.0 for some time now and are increasingly developing into a production system supplier for networked production in the digital factory", says Arburg Managing Partner Juliane Hehl, referring to Arburg's main focus at the Fakuma 2015. Photo: ARBURG

Arburg’s some of the plastic part producing systems for AM users are: allrounders, freeformers, the ARBURG host computer system ALS and integrated automation. Arburg’s freeformer produces complex components from common plastic granules without a mould through industrial additive manufacturing, which customise injection-moulded mass-production parts.

Unique versions of various office scissors can be made using an electrical Allrounder 370 E, which first moulds plastic handles onto the stainless-steel blades, onto which a particular code is then lasered, and optionally customised 2D or 3D lettering is applied with the laser or Freeformer.

An example of networked production is the Freeformer which enhances injection-moulded rocker-type light switches with a customised symbol/name combination in large volumes. Here also, the product itself becomes an information carrier with a code applied by laser.

Arburg’s host computer system (ALS) seamlessly documents all relevant process parameters and forwards these to a web server. A web page which displays all the relevant process data can be opened via the unique code using mobile devices. Each individual part can be seamlessly tracked in this way.

Arburg’s physical foaming of thermoplastics is an innovative application for the automotive industry. It enables significant material savings in automotive plastic parts and thus a reduction in fleet consumption and CO2 emissions.

Electrical two-component Allrounder 470 A manufactures buttons for car interiors from liquid silicone rubber (LSR). The diaphragm of the moulded part is manufactured from coloured LSR.

Hydraulic two-component Allrounder 570 S produces handles for garden saws from 40 percent glass fibre-reinforced PP and haptically appealing TPE.

Hybrid Allrounder 820 H has been specially configured in the “Packaging” version for applications in the packaging industry and will produce small folding baskets (175 x 175 x 85 mm) for fruit from PP in a cycle time of around five seconds.

Electrical Allrounder 470 A, for the field of medical technology, produces connecting pieces (Y-connectors) for infusion therapy with an 8-cavity mould from Männer. The cycle time is around 15 seconds. The highlight of this application is the side injection through a needle-type shut-off nozzle and the demoulding from three sides of PMMA moulded parts.

The micro production system based on an electric Allrounder 270 A, is equipped with a new micro injection unit and a compact, horizontal Multilift H 3+1 for the reliable separation of micro component and sprue. The system manufactures four micro counter wheels in a cycle time of 12 seconds. Nine components weigh as much as a single granule of PBT material.
