IML Systems with Vision Inspection Beck Automation of Switzerland (U.S. office in St. Louis; beckautomation.com) is now offering turnkey in-mold labeling (IML) systems with integrated, flexible vision inspection systems from Intravis GmbH in Germany (office in Norcross, Ga.; intravis.de). No longer just for premium IML systems, optical inspection has become a "must- have" feature, according to Beck Automation. The IMLWatcher vision system (also available separately from Intravis) can check for label presence, label identity, label position, blow-by, pin marks, wrinkles or blisters, contamination, printing defects or misalignment, and label edge defects. Accuracy is 0.1 mm (for a 50 x 50 mm label) and maximum test speed allows imaging intervals as short as 20 millisec. Flexible software is said to adapt to a wide variety of IML tasks. Distance between the labeled part and camera lens can be freely adjusted by means of a servo to compensate for different sizes of parts. Overall, the system can inspect a wide range of objects such as lids, tubs, trays, buckets, and all common types of labels, including bands and bottom labels. Processing Technologies International LLC (PTi), Aurora, Ill., has launched the Super-G High-Speed Extruder line for processing sheet from PP and HIPS. Two models are available that reportedly deliver significant performance advan- tages and overcome the limitations of competitive machines. The Super-G SGHS3000-36D has a 500-hp motor and runs at up to 1000 rpm, while the Super-G SGHS3000-42D has a 600-hp motor and max. speed of 1200 rpm. While each is capable of running even faster, PTi sets the maximum rated speed at an upper motor- load threshold of 85%. For processing PP, the Super-G SGHS3000-36D puts out around 3000 lb/hr. The extruders boast an oversized feed section, which promotes higher regrind feed rates (up to 70% or more), along with a streamlined feed hopper with support, delivery chute, and tramp-metal protec- tion. Feed screws are removed from the back. Other key features include an easy- cleanout vent chamber and linear-bearing barrel-glide support (patent pending). Special air-cooled heater and blower assemblies limit the exterior heater temperature for safety and efficiency to less than 110 F while competitive models can get up to 500 F. The extruders feature carbide-lined barrels and Colmonoy hard-faced screws, instead of the case- hardened screws featured on competitive models. These extruders are said to deliver not only high speed but improved melt quality as a result of PTi's Super-G Lobe screw technology. The machine is said to be very energy efficient (i.e.; PP at 6-7+ lb/hr/hp) and features a compact footprint of 17.5 × 4.5 ft (5.3 × 1.4 m). A Model SGHS3000-36D will be ready later this spring for demon- strations and customer trials at PTi's new Technology Development Center. 630-585-5800 • ptiextruders.com INJECTION MOLDING EXTRUSION High-Speed Sheet Extruders for PP, HIPS 66 APRIL 2017 Plastics Technology PTonline.com Keeping Up W it h Technolog y
