Husky Injection Molding Systems has upgraded its HyPET system with the aim of eliminating waste and variability in the preform manufacturing process.

The HyPET system includes a simplified user interface and operator control, improved flexibility for mold changes and faster cycle time options.

Husky said combined with an electric screw drive, these improvements result in up to 5% lower energy consumption than the previous generation HyPET system.

All components of the system, including the hot runner, mold, machine, robot and post-mold cooling, are designed to work together as a fully integrated workcell.

It is capable of outputs from 360 to 110,000 preforms per hour and is available in seven sizes ranging from 90 to 650 tonnes (100 to 715 tons) for molds between two and 192 cavities.

Minimise variability

Robin Lovell, business manager for PET systems at Husky, told the aim of the system was to maximize quality, efficiency and minimize process variability.

“As the only supplier to provide a complete fully integrated preform injection molding solution, Husky is able to streamline how each discrete component works together to deliver industry-leading performance.

“We have made system level improvements to our High Performance Package (HPP) system that optimizes management of the melt stream from pellet to part, resulting in higher preform quality and a significantly improved ability to mold thinwall preforms.

“For example, for a 500 ml still water application it is possible to manufacture a preform with a side wall as thin as 1.5 mm and thread wall of 0.8 mm.”

HPP system

Many of the technologies from the HyPET High Performance Package (HPP) system have been added to HyPET’s components and sub-systems.

This allows molders to leverage the preform quality, ease of operation and process repeatability benefits that have been proven on several hundred HPP systems, said the firm.

Commonality between the two product versions also means reduced training time and maintenance costs and savings in spare parts inventories. 

Husky added that it is designed towards compatibility with future technology developments.

Lovell said they see an increased need to maximize the productivity of the installed base of equipment in the field. 

“We will be launching a range of services and products focused on doing just that, enabling customers to increase the operational efficiency of the existing equipment they have already had great success with.”
