CoolCross simplifies same plane cooling


The latest additions to the Hasco mould components catalogue includes CoolCross, a novel device that allows injection mould cooling circuits to cross in the same plane. CoolCross makes it possible


to reduce the thickness of the mould plate, allowing the use of shorter nozzles and guidance elements, and to reduce the number of cooling channels. This is claimed to result in reduced component costs as well as faster mould construction times. The CoolCross Z99 system is claimed to allow homog- enous temperature distribu- tion to be achieved in cores or mould inserts . Cavity cooling is maintained throughout the moulding cycle and hot spots are avoided. The positive locking mechanism is also said to eliminate the risk of


Compact heating


Türk+ Hillinger has introduced the HPO heater, a compact heater element designed for applications in hot runner nozzles. The new heater incorpo-


rates a self-locking feature and revised geometry that is claimed to ensure gap-free thermal transfer from the heater to the nozzle while ensuring it can be easily removed even after prolonged periods of use. ❙ www.tuerk-hillinger.de

❙ RUD’s Tool-Mover is a portable device intended for safe handling of injection moulding tools in the toolroom and moulding shop. Equipped with a frequency- controlled drive system for maximum precision during rotation of the mould, models are available with maximum capacities of 6, 10, 16, 20 and 32 tonnes. www.rud.com


unintended closure of the channels. Hasco has also introduced the Z9672 series of deflectors, which are claimed to improve the direct cooling of core pins used to create blind holes in cavities. Manufactured in brass with Viton seals, the devices are said to improve heat extraction.


Staying in the cooling area,


the company recently an- nounced that the marking rings and system hoses for use with its Push-Lok cooling system are now available in blue, red and yellow. The simple colour options are intended to simplify cooling circuit identification. ❙ www.hasco.com


Synventive adds pin monitoring option


Synventive has added a valve pin monitoring option to its ActiveGate product line. The valve pin position


monitoring module can be added to any ActiveGate system to monitor the pin position at any point in the process. The data can be used for process management purposes or to trigger additional actions. The monitoring technology can be used with the com-


pany’s original servo-electric powered eGate systems, and with the more recently introduced pneumatically- activated nuGate and hydrauli- cally-activated hGate systems. “The ActiveGate line is


enabling technology allowing moulders to produce parts they simply couldn’t before,” says Synventive VP and General Manager Steven Gayfer. ❙ www.synventive.com


❙ ToolQuote is a mould quoting software package from Canadian company JDL Technical Services designed to provide fast and accurate costing estimates. Key features of the programme include automatic tool layout generation, creation of multiple tool profiles for quick comparative estimat- ing, and full quote history tracking. The ToolQuote software can be applied to both single and multi-cavity mould designs, says JDL. www.jdltech.ca


❙ German plasticising screw manufacturer Groche Technik has developed an ‘active’ non-return valve that is currently undergoing pilot production trials with a number of key customers. The new design uses a “spring and bolt” arrange- ment to automatically lock the non-return valve in the closed position before injection commences. This eliminates any leakage and is achieved without the use of additional electric motors or control equipment, the company says. www.gt-plast.de
