Arburg is bringing a complete range of plastic parts production systems to CHINAPLAS 2016, from one-off parts manufactured by Freeformer to high volume production with Allrounders injection molding machines.
A “Packaging” version of Arburg’s hybrid Allrounder specially designed for thin-walled applications in the packaging industry is presented at the show.
The hybrid Allrounder 570 H with a clamping force of 1,800kN produces four 200ml butter boxes in a cycle time of around 3.2s. A 2+2-cavity stack mold is used in the In-mold Labeling (IML) application, which allows for smaller-sized machines to be used compared with conventional four-cavity mold.
Automation is handled by a two-axis robotic system. This inserts two so-called butterfly labels on the fixed and moving mold platen and removes the finished parts from the center block.
In another demonstration, an all-electric Allrounder is used to produce pill splitters for medical use made from polycarbonate (PC) on an eight-cavity mold. The cycle time is around 25s and the part weigh is 18g. A Multilift Select robotic system from Arburg is used for demolding.
In addition, a Freeformer additive manufacturing machine demonstrates the production of pill splitters for medical technology use from PC in small volumes.
Once the supporting structures have been removed in a water bath, the two-piece articulated part can be used as a design prototype or for functional tests, for example. This means that expensive aluminum molds can be dispensed with and new products can reach series maturity much faster.
