"I don't like to build what people want; I like to build what they need," Robert Schad told PlasticsToday upon the public debut of his new hybrid molding machine company, Athena Automation (Toronto, ON), at an open house coinciding with the recent Plast-Ex 2013 show (May 14-16; Toronto, ON).
Most anyone in the plastics processing industry will recognize the name of the iconoclastic founder of Husky Injection Molding Systems, which the German-born Schad built into one of plastics' most dominant injection molding machine makers, especially in the PET preform and closures market.
If Schad sounds a bit like Apple's Steve Jobs he has good reason. The visionary, no-nonsense leader recognized the virtues of vertical integration early on, meaning Husky not only made injection molding machines, but also molds, hot runners, robots, and auxiliaries.
Schad eventually left behind the company he built after selling his majority stake in 2007 to Canadian private-equity investment firm Onex in a deal worth C$960 million overall. "It didn't work out to stay," he says simply.
But Schad found he couldn't leave behind what he'd been doing since founding Husky in 1953 as a small machine shop. Originally intending to build air-boats after Husky, his attention soon returned to the plastics processing machinery he knows so well, and the Athena concept was born in 2008.
"When I started, I set some very precise goals," he says of Athena. "I would either accomplish them or give up."
"The main idea is to build a simple, cost-effective platform with energy consumption similar to all-electric injection molding machines. It can now be automated with the features needed all built into the machine. It's simple to install, and can be customized very quickly and cost effectively," Schad says.
The Athena line utilizes servomotors in a hybrid platform to achieve repeatability and accuracy "as good as or better" than all-electrics while maintaining low energy consumption in part due to the active power supply that regenerates braking energy. The machines have a small footprint with large daylight and are quiet, operating at under 70 dB.
The Athena machines will range from 150 to 500 tonnes, with screw diameters of 30-120 mm.
A clean-slate, and cleanroom-ready design philosophy are at the heart of the Athena approach. The machines are built on a one-piece base and feature distributed controls interconnected by a PowerLink bus. All machines feature 150 mm of floor clearance for easy cleaning. All service connections (water, air, vacuum, electrical) are located at the injection end of the machine. Services are pre-routed through the machine base.
Also standard are two-platen electric clamps with non-lubricated tiebars and a closed loop, leak-free oil return system for hydraulic components.
A wide range of options include a fully integrated high-speed, side-entry robot, stack-mold carrier, integrated dual injection, and integrated hot runner and robot control, meaning the machines can quickly be adapted for in-mold assembly and rotary cube automation.
