Atlanta — A company from Cyprus, Cypet Technologies Ltd., has developed a new technology for one-step injection stretch blow molding — and at K 2019, it produced a giant 120-liter PET drum at the show. Single-stage blow molding machines injection mold PET preforms and blow mold them on a single machine. A conventional single stage uses a vertical clamp to injection mold preforms, then a horizontal clamp for blowing bottles. Cypet’s technology works in the opposite way. Constantinos Sideris, managing director of Cypet, described how his company’s machine works in a presentation Sept. 17 at the SPE Annual Blow Molding Conference in Atlanta. “In our technology, we mold the preforms horizontally so that the opening direction of the mold is horizontal. And we blow the bottles vertically so that again, the mold opening is horizontal,” he said. “This means that we can put the blow mold and injection mold on one and the same clamping unit, and we open and close both molds together. This is a substantial difference in the mechanics.” Sideris said the Cypet technology is patented in major countries — those that represent 80 percent of global GDP. The C...
