Call it IMM alley: In the 240 block at one end of the São Paulo Expo center, injection molding machine (IMM) makers Wittmann Battenfeld, Engel and KraussMaffei are lined up, side by side, displaying their wares to Plastico Brasil visitors, which were plentiful on day two of the show. Arburg, Sumitomo (SHI) Demag and Brazil’s own Romi stood apart in other parts of the hall, but all of these companies shared a common purpose: To showcase their newest technologies to a market seen by many to be in full economic recovery.
Wittmann Battenfeld (Vienna) features a MacroPower machine with integrated robotics and the Unilog B8 control system powered by the company’s own 4.0 technology at booth F242. The MacroPower 650/3400 with a 6,500-kN clamping force is molding wheelchair wheels in a 75-second cycle time. The mold is supplied by Technoplast Brasil and automated insert molding of the metal parts and wheel removal was designed and developed by Wittmann Battenfeld’s Brazilian subsidiary.
Right next door, at booth E242, Engel (Schwertberg, Austria) is running an e-motion 440/160 molding polypropylene ice cream cups in a four-cavity mold with a total shot weight of 14.8 grams. Thanks to in-mold labeling (IML), the cups are ready-to-fill when they leave the integrated production cell. The cycle time is 2.2 seconds. IML technology makes it possible to change cup decoration without interrupting production, said Engel.
The system setup is a model of European collaboration: The mold is supplied by French company Simon; IML automation is developed by Germany's Beck automation; the labels come from Belgium’s Verstraete; and the polypropylene hails from Austria’s Borealis.
Another block over at booth D242, KraussMaffei (Munich, Germany) is showcasing its all-electric PX 160-540. The machine achieves injection speeds up to 500 mm/second and is suited for thin-wall molding applications. At Plastico Brasil this week, it has been purposed to mold ice cream cups from polypropylene supplied by Braskem (which supplied resin to many of the machine makers at the show). Cup samples filled with tasty treats are being handed out at the welcome desk.
In-mold labeling is also a star attraction at the Arburg booth (I106). A hybrid Allrounder 720 H (P) with a clamping force of 2,900 kN is equipped with a hot-runner mold from Brazilian company RK Ferramentaria. The machine produces six 250-ml polypropylene tubs in a cycle time of around five seconds. Each part weighs 13 grams. Automation systems provided by partner company Campetella handle the insertion of IML labels from Verstraete into the mold and stack the finished tubs on a conveyor belt.
Local hero Romi (Santa Bárbara D’Oeste, Brazil) displayed its machines on a 500-square-meter prime piece of real estate on the show floor. One of the highlights at booth E106 is the EN 220 machine with the “stop and go” system that improves speed and precision while lowering energy consumption. The machine is suitable for PVC production, PET pre-molds and multi-material and multi-color injection molding, said the company.
At booth B070, Sumitomo (SHI) Demag (Schwaig, Germany) is running a Systec SP 350-1450 machine. The hybrid drive concept reduces production-related energy costs by as much as 60%, according to the company. The System SP series was tailored to accommodate the requirements of the packaging industry.
Plastico Brasil, which runs through March 29 at the São Paulo Expo exhibition center, is an initiative of the Brazilian Machinery and Equipment Builder's Association ABIMAQ and the Brazilian Association of the Chemical Industry (ABIQUIM) and is organized by Informa, the publisher of PlasticsToday.
