German mold tooling components producer Hasco Hasenclever GmbH & Co. KG has introduced a flexible mold-temperature control line.
Hasco featured the new line and other mold components at its booth at Expoplast 2012, held Nov. 14-15 in Montreal.
“It reduces pressure loss because there are no sharp angles,” said Christoph Pischel, business development manager for North America, in an interview at Hasco's booth. “It's less costly to make [than conventional mold-temperature control lines drilled into mold plates].”
Pischel said the TempFlex products cool quicker than conventional channels embedded in the mold because the flexible lines are made of braided stainless-steel hoses with quadratic cross sections and change direction through arcs rather than abrupt corners. The Lüdenscheid, Germany, company says the lines are simple to assemble and adaptable to the desired groove process.
“Elaborate, deep-hole bores and high pressure losses due to 90-degree deflections are a thing of the past,” Hasco claims. According to the company's calculations, deflecting the coolant in the new lines through 10 arcs rather than through 10 conventional 90-degree deflections results in 300 percent less pressure loss.
TempFlex is available in metric and Imperial measurements. Hasco claims the lines can be retrofitted onto existing molds plagued by insufficient cooling performance.
