Arburg Inc. (Booth S46048) is running a toy race car on an injection molding machine equipped with a turning-cube mold that does in-mold labeling and in-mold assembly on a single press.
The Allrounder 520A press has a clamping force of 165 tons and is equipped with a small-accumulator hydraulic system. Electroform Co. Inc. supplied the cube mold. The press molds an assembled, labeled car in a cycle time of 15 seconds.
Production is divided into four steps. The mold has two adjacent cubes, one facing the rear of the machine and the other facing the operating side. The body, with the race car label molded in, is molded in the first cube. The underbody and the wheels are made in the second cube, and are preassembled to form the chassis.
Both cubes come together to complete the assembly of the car.
Each cube has four faces with identical cavities, so all four production steps take place simultaneously in each cycle. After each cycle, the cubes rotate 90 degrees to reach the next position.
An Arburg Multilift robot picks up a label to insert in the first cube, and removes the finished race car from the other cube.
The press features elements of Arburg's electric Alldrive technology with standard servo-electric drive on the main axes allowing simultaneous movements and short cycle times. Depending on requirements, the auxiliary axes can be driven hydraulically or using a small-accumulator hydraulic system.
On another press, Arburg is molding two materials liquid silicone rubber and Ultem polyetherimide into a finished outlet valve with LSR hoses for coffee machines. The two-component press is a 220-ton Allrounder 570A, arranged in an L-configuration. The thermoplastic material is injected from the rear of the machine, while the LSR is injected through the fixed platen, in the conventional manner.
