CHICAGO (Sept. 19, 5:50 p.m. EDT) — R&D Tool and Engineering introduced a quick-change lower blow system for injection stretch blow molding tools that not only can save molders time now, but also save them money on future mold purchases.
The unit allows molders to use a standard universal back plate on multiple molds, meaning that they will only need to buy a lower system for future programs, quickly swapping it out through R&D quick connectors to speed mold changes, said Bart Pace, director of sales and marketing for the Lee's Summit, Mo., company.
Beyond cost savings on future mold purchases, using the standardized base also should speed time to market for future products because there will be less work required on those tools, Pace said during a June 20 interview at NPE 2006 in Chicago.
The program will not work on every mold, but it is an option for most, he said.
R&D also introduced its Genesis hot-runner system for the injection blow mold industry. The company had Genesis available for injection stretch blow molding three years ago, and many customers involved in both molding programs wanted the expansion into injection blow molding, Pace said.
The Genesis format is designed to work on Uniloy or Jomar machines, with a proprietary melt-delivery system to balance resin flow to each nozzle.
Internal adjustable metering devices allow for a fill balance that he said is more than 90 percent accurate, for fast color changes.
