Sumitomo (SHI) Demag presents all-electric IntElect series at PLAST trade show in Milan 

#

Schwaig, May 30, 2018 – Sumitomo (SHI) Demag Plastics Machinery GmbH in Schwaig near Nuremberg/Germany turns the spotlight on the new IntElect series of all-electric injection moulding machines at PLAST 2018 in Milan. Applications will be demonstrated live on three exhibits between 29 May and 1 June on Stand D162 in Hall 24. These exhibits will include two integrated system concepts with robots and a conveyor belt. 
 
Exactly one year ago, Sumitomo (SHI) Demag introduced the second and, therefore, latest generation of IntElect all-electric injection moulding machines, which was primarily intended to impress through its compact dimensions, optimum tool protection, high-precision drive technology, greatly improved energy efficiency and ergonomics and an optimum price-performance ratio. When launched, this series encompassed five different models with clamping forces ranging between 500 and 1,800 kN. In the opinion of Product Manager Peter Gladigau, the years dedicated to the development of the highly dynamic drives proved particularly worthwhile, and the conclusions he draws are extremely favourable. “40% of the machines we sold over the past 12 months were from the all-electric IntElect series, and that's well above the Euromap average of around 20% for all-electric machines.” This latest upgrade follows the successful market launch of the new IntElect series a year ago. In order to meet the demands of high-speed applications, 2018 sees the introduction of the IntElect S (Speed), designed for thin-walled parts, which runs with injection speeds of between 350 and 500 mm/s and cycle times of between 3 and 10 seconds. Compared with the standard IntElect machine, the high-performance model offers cycle time reductions by up to one second. 
 
High-speed packaging application with extraction robot and conveyor belt
 
Sumitomo (SHI) Demag demonstrates the Speed version of its all-electric injection moulding machines in Milan with an exemplary application for the packaging sector. Oval PP lids with a shot weight of  33.5 grams are produced for food packaging on an IntElect S 180-700 with a clamping force of 1,800 kN complete with robot, protective housing and conveyor belt. The single-cavity hot runner valve gate mould is supplied by Incos Stampi srl.  The SDR 5-15 speed robot descends into the open mould from above and deposits the parts on the conveyor belt. A lid is produced at cycle times of less than 5 seconds, thanks to perfectly tuned system components. Minimal robotic action of less than one second is due, among other things, to a laser-printed gripper with optimised weight. “The newly developed high-torque drive motors achieve impressive dynamics on the axes, especially in high-speed medical technology applications or for precision Live medical technology presentation: Threaded rod for insulin pen
 
An IntElect 130-450 with a clamping force of 1,300 kN represents the medical technology growth market at PLAST in Milan, a sector which is exceptionally important for Sumitomo (SHI) Demag.  Efficient zerodefect manufacturing achieved through precision and repeatability – keywords that the German-Japanese injection moulding machine manufacturer associates with this machine. The production of a threaded POM rod for an insulin pen on a 16-cavity mould from KEBO will be demonstrated live. The mould temperature control system is from Piovan. With part weights of 1.57 grams and a shot weight of  25.12 grams, the cycle time is an excellent 10.6 seconds. 
 
Compact, efficient, automated: Carabiners produced with the IntElect2 50/360
 
Last, but by no means least, Sumitomo (SHI) Demag demonstrates the production of a carabiner made of POM using a Polyplastics dual cold runner mould on an IntElect 50-110 which, with a clamping force of 500 kN, is the smallest machine in the series.  The current IntElect generation exploits all its design advantages in the system concept. SDR 5S robots, which are new in the SDR portfolio particular for small weights, and protective housings, a conveyor belt and downstream equipment with top-mounted dryers, top feeders, a regrind metering system, cooling unit and grinders are integrated in the smallest possible space in a compact machine, which is only 400 millimetres wider than the standard model. The compact “pick & place” robot sits atop of the machine, with the necessary safety housing being integrated into the machine itself.  One minor, but important advantage should also be mentioned: CE conformity is confirmed for the entire machine and robot in a single declaration, thanks to this combined solution. A thermal imaging camera from Micro-Epsilon is integrated into the machine control system for inline process control. Parts are inspected based on stored target temperatures and rejected if necessary.
