Easy-to-install manifold and smarter controls at Chinese fair.

At April’s Chinaplas show in Shanghai, Husky Injection Molding Systems, Bolton, Ont., introduced two new hot-runner products. One is the Unify manifold system (photo), designed for simple, one-step installation without preheating, reducing installation time by up to 70%. Water, hydraulic, and electrical services are attached to a rigid frame precisely matched to the manifold layout, allowing easy installation directly into the mold. Husky’s patented Ultraseal technology is said to ensure leak-free nozzle alignment to the gate without preheating and to eliminate risk of damage to the tips during installation.

Craig Reynolds, Husky’s director of business development for hot runners and controllers, called the Unify line a re-entry of sorts by Husky into the automotive market. Recently, the company has stressed its focus on packaging and medical markets. While those are growing segments in China, the country’s automotive industry remains dominant. “We realized we were probably a little hasty in exiting all automotive,” Reynolds said at the show. This summer, the company will introduce new valve-gate technology it says “will make vestige marks disappear.” Reynolds said the new technology will produce a mark like that of an ejector pin.

Also at Chinaplas, Husky introduced the Altanium Matrix2 hot-runner temperature controller, offering additional functionality over the firm’s Neo2 and Delta3 systems, with control for two to 254 zones. The system has a 19-in. color touchscreen and automatic storage and recall of previous job setups. It is described as being “smarter and more intuitive than other controllers on the market,” shortening the learning curve for new users. Integrated mold protection prevents material degradation, and real-time power-deviation monitoring automatically detects signs of melt leakage or heater failure.
