BOY’s love model trains! CHRISTMAS this past year was exciting for everybody, but especially so if you were the lucky recipient of a model railway from Märklin. Despite modern electronic toys, the products of traditionrich Märklin of Göppingen remain in high demand worldwide. And supporting the production of these timeless models is German company Dr. Boy GmbH & Co. KG. During 2010 BOY delivered two injection moulding machines with clamping forces of 350 kN and two BOY 22 A machines (clamping force 220 kN). In December Märklin gave BOY a followup order for two more BOY 35 E machines. The energy efficient BOY E-series machines convinced Märklin that they had established the right direction for the future. “The BOY 35 E with the servo drive fits like a glove into our production”, said Wolfrad Bächle, managing partner and responsible for the production at Märklin. “Since we have an enormous number of plastic parts for our railways, railway cars and rail material, we also have a large number of moulds. All of them fit without problems in the BOY 35 E, as the four tie-bar machine has extremely generous distances between the tie bars and platens,” he added. The BOY 35 E is the most compact in its tonnage range and requires a footprint of only 2 m². The machines run in a three-shift operation under full steam. In addition to some of its other features, the extremely low energy requirement of the machine has helped decrease production costs. www.dr-boy.de

Threaded nozzle for hot runner systems Nozzle design provides leak-proof operation SYNVENTIVE Moulding Solutions has introduced a new leak-proof threaded nozzle, the 09E, for use with its line of ‘Plug ‘n Play®’ unitized hot runner systems. The 09E threaded nozzle is available with both thermal gate and valve gate options. It features a 9mm internal flow bore (with 30mm mould cut-out) and is ideal for medium-sized part applications with maximum shot weights of 250 grams per nozzle. Since these nozzles are threaded directly into the hot runner manifold, a leak-proof system is provided without critical stack-up dimensions that must be maintained. These nozzles are externally heated and are available in lengths from 60-400mm. The heaters
are easily replaceable and have integrated, replaceable thermocouples. The 09E nozzles are the latest addition to the Synventive ‘Plug ‘n Play’ hot runner system product line. Synventive ‘Plug ‘n Play’ systems are fully preassembled and tested, and are shipped ready to install in the mould. As such, they greatly reduce the amount of time normally spent assembling, adjusting, and mounting the hot runner system into the tool. Synventive ‘Plug ‘n Play’ systems are designed for use in demanding applications including automotive, premium consumer and electronics. www.synventive.com
Borouge invests in complete pipe extrusion line for new innovation centre BOUROUGE has ordered a complete polyolefins (PO) pipe extrusion line from KraussMaffei Berstorff for its new Innovation Centre in Abu Dhabi. The order package comprises the KME 60-36 B/R single-screw extruder in the successful 36D Series, the KM-RKW 32 and KM-RKW 33 pipe heads, and corresponding downstream components for the diameter range from 12 to 63 mm. Borouge chose KraussMaffei Berstorff because of their extreme efficiency and high flexibility in the use of different materials. The system will

be used in the innovation centre’s laboratory to test development stages of various PO materials such as HD-PE, LD-PE, PP-HM or PP-R and also produce pipes of 12 to 63 mm at line speeds of between 2.8 and 100 m/min. The line is equipped with two pipe heads in order to ensure a quick and flexible product change. Borouge’s Innovation Centre will work together with the European innovation centres of Borealis as well as with local and international educational institutions such as the Petroleum Institute of Abu Dhabi, to further develop the competence of polymer science in the United Arab Emirates.
