Husky’s closely-guarded HyCAP HPP closure production system uses a novel new mould technology and optimised mechanicals to cut cycle times by up to 20%
Husky’s HPP caps productivity gains
Working effi ciently means doing exactly what is needed; nothing more and nothing less. And that is the claim that Husky Injection Molding Systems is making for its new HyCAP HPP system for high output production of caps and closures. The HPP production technology was introduced at the Chinaplas trade show earlier this year. Details of the system are being kept tightly controlled prior to its full commercial launch next year; the system demonstrated in Shanghai was shielded from public gaze by an enclosure around the mould area. What the company was not keeping secret was the productivity improve- ment – a claimed 20% faster cycle time over the best closure production systems on the market today and a similar gain in energy effi ciency over its own previous best.
At the Chinaplas launch, Husky’s vice president of
marketing Jeff MacDonald said: “HyCAP HPP provides exactly what customers have been seeking – a closure manufacturing solution that combines the advantages of injection moulding with part-cost economics comparable to compression moulding.”
www.injectionworld.com The productivity data supplied by the company is
impressive. The HyCAP HPP 300 system running at Chinaplas in April was producing a 1.2g 29/25 light- weight water closure on a special 72-cavity KTW mould at a cycle time of 1.85s. Earlier the same month, but on another continent, the company ran an example of its current state-of-the-art cap production technology. That HyCAP 300 system, which was running at the NPE fair in the US, used a conventional 96-cavity KTW mould and produced 0.95g 26/22 lightweight water closures on a cycle time of 2.2s. The HyCAP system running at NPE was the fi rst
Husky closure production system to benefi t the company’s newly-acquired system capability in this sector; last year it bought Austrian closure mouldmaker KTW, adding its leading position in beverage and specialty closure mould technologies to its existing moulding machine and hot runner know-how. The new HPP system exploits that system capability further still. “The acquisition of KTW made Husky the closure
