At the Chinaplas show last month in Shanghai, Husky Injection Molding Systems Ltd., Bolton, Ont., demonstrated “the industry’s highest-output system for finished water closures,” according to Mark Fitzpatrick, business manager for closures. The system produced more than 1900 closures for water bottles per minute from a 96-cavity mold. That means less than 3-sec cycles, vs. industry performance of a little under 4 sec up to 5 sec, he said. The caps were molded with a Husky Hylectric 400 system having a 440-ton hydromechanical clamp and electric-driven reciprocating screw, as well as a mold from Corvaglia of Switzerland. Speed was improved through new control software that overlaps more functions for a faster dry cycle. The closures boast improved tamper-evidence because the band breaks before the seal on the bottle’s contents is broken. The caps produced at Chinaplas weighed less than 1.8 g, vs. a typical 2.1 g for Chinese caps. Though the design is different from Western water-bottle caps, Fitzpatrick says the cycletime improvement would apply to production here, as well. (905) 951-5000 • www.husky.ca
