Young people use the word “extra” to denote something that’s a bit over the top. A little much.
But “More” — the newest line in Arburg’s portfolio of Allrounder injection molding machines — offers a less cynical promise: More space, more flexibility, greater ease of use. In short: More of what multi-component molders might need.
Based on the original Allrounder machines and boasting a bevy of beneficial extras, the series was slated to make its debut at Fakuma Oct. 12-16 in Friedrichshafen, Germany.
“We very much look forward to the Fakuma trade fair, at which we shall be showcasing the new Allrounder More, which covers requirements down to the smallest of details,” said Gerhard Böhm, managing director of sales and service for Arburg.
Available for now in two sizes — with clamping forces of about 180 tons and 225 tons — the modular machines are intended for the production of multi-colored or multi-component parts, such as rigid plastic toothbrushes with rubbery grips.
Each press has two electric injection units, one horizontal and one vertical; Arburg intends to eventually offer several possible injection positions, making possible all common two-component applications.
According to the company, the machines have highly dynamic electric toggle-type clamping units with energy-efficient liquid-cooled servo motors. They offer plug-in media couplings that simplify changeovers and maintenance.
To facilitate access to the mold and make mold changes easier, the presses have larger mold capacities and ejector strokes than the original Allrounders, and greater distances between tie bars than other comparably sized machines. The tie bars and moving platen have each been extended by about 7.9 inches. The distance between tie bars is about 1.8 feet, and the maximum platen daylight is 3.9 feet. The sliding guard has also been widened by 1.3 feet.
Maintenance and ease of operation are additional points of emphasis for the machines. For example, technicians can change the cylinder module in a few easy steps. In addition, the machines are designed so that material is fed outside the mold area, preventing contamination by unprocessed pellets. Hose guides optimize hose routing and prevent possible chafing marks.
