technology | Moulds and components Zahoransky targets cycle savings


German mouldmaker Zaho- ransky has developed its SCPS Light mould design to allow producers of single component injection mouldings to incorpo- rate assembly or additional cooling routines without compromising cycle time. SCPS Light moulds draw on


the technologies used in the company’s TIM multi-compo- nent paternoster moulds. They allow an integrated external work station to be used for tasks such as placement of inserts or metal parts. These pre-loaded parts can then be delivered to the mould as the parts are removed from the previous cycle, eliminating any extension of the overall cycle time. Alternatively, the external


more advanced version of the Light design that allows more than one external process to be integrated into the mould- ing cycle. For example, a first station might be used to insert metal parts, a second step could allow additional cooling and/or printing of the compo- nent, a final station could be used for robotic unloading. All movements in the SCPS


station can be used to provide an additional cooling cycle. According to Zahoransky,


“outsourcing” additional operations to a dedicated station outside of the mould can lead to a substantial saving


in cycle time. And, as they are no larger than a standard single component design, the SCPS Light moulds can be run in existing moulding machines. The company also offers an SCPS Flex version. This is a


Flex system are made using servo drives to provide high positional accuracy and independence from the injection mould hydraulics. Control is also integrated into the mould, with connection to the injection machine via a standard Euromap interface. ❙ www.zahoransky.com


Roehr Tool adds to collapsible core options


Roehr Tool Corporation has extended its line of Dove Tail (DT) line of collapsible cores with the addition of a number of new sizes and configurations. The company has engineered a number of new DT Cores in the sub-10mm


category for moulding very small threaded parts for applications such as medical devices and electrical connectors. By keeping the required blanks ‘on-the-shelf’ it says it is now able to deliver DT cores in the range from 7-10mm diameter up to four weeks faster than in previously. Roehr has carried out a similar pre-engineering process with DT cores


for NPT and BSPT threaded applications. The company has also extended the number of standard pre-engineered DT Cores from four to 23. ❙ www.roehrtool.com


Husky targets costs with UltraHelix designs


Husky claims its latest UltraHelix valve gate technol- ogy offers the lowest cost of ownership on the market today. According to Dave Morton,


Vice President Americas for Husky’s Hotrunners and Controllers business, the newly introduced design is

easier to integrate into the manifold, provides a superior gate vestige, and is designed for 5m cycles without need for any repairs. The company claims the


new valve gate is manufac- tured with improved stem-to- gate orifice concentricity,

which virtually eliminates mechanical wear during use. It also uses a new removable heater design that is said to combine ease of replacement with the levels of performance expected of integrated designs. Morton says the perfor-


mance of this heater arrange-


ment, which features the thermocouple brazed into the nozzle ring, is so consistent there is no need to rebalance a mould in the event a heater has to be replaced. For the same reason, mould qualifica- tion times can be reduced. ❙ www.husky.co
