News from Husky Injection Molding Systems Ltd. includes a two-platen press design with improved hydraulics, a nozzle tip and a PET preform shuttle.
Husky designed its Index Shuttletable post-molding device to work with its Index high-volume injection preform molding machines. It prevents blemishes caused by free-dropping the preforms onto a conveyor. The device shuttles preforms out of the molding area to a transfer table that cools and delivers them to a take-off robot.
The Shuttletable replaces the final cooling stage on the revolving-mold Index system, increasing cooling and reducing overall cycle time. The preforms also stay properly oriented for downstream operations such as gate cutting, thread recrystallization and blowing them into bottles.
Quadloc injection presses, in clamping forces of 1,500-8,800 tons, are based on Husky's two-platen design, first introduced in 1995. Improvements include a Polaris control and, in the hydraulics, the latest Moog servo-valves. The Bolton, Ontario, press maker says new ejector valves can do “controlled aggressive” acceleration and deceleration at high speed, to protect molds better and reduce part damage. Updates to the position transducers improve accuracy and repeatability.
Husky has expanded injection unit capacities, now offering 38 different combinations of clamp and injection units.
To boost energy efficiency, a modular power concept lets molders pick the right power level for each application.
Electric screw drives are available.
The UltraFlow nozzle tip yields a part with an improved surface finish and a uniform color, even when molding with metallic- and platelet-filled resins. By thoroughly mixing the resin using its interior helical grooves, UltraFlow prevents weld- and flow-lines that begin in the runner system.
In global developments, Husky has established four regional offices in China—in Shanghai, Zhuhai, Beijing and Chengdu. Husky plans to add more than 20 marketing and manufacturing support people in China. The Shanghai facility includes a 10,000-square-foot technology center with six machinery bays able to handle presses as large as 1,000 tons.
Husky also established a Systems Group in Hong Kong to do engineering and project management services, such as designing integrated work cells and turnkey factories, and to do factory audits.
