StackTeck adds servo-driven mold capability

StackTeck Systems Ltd. (Brampton, ON, Canada), a manufacturer of high-production molds and integrated molding systems for the global thin-wall packaging, food and beverage, cap and closure, and medical markets, announced it has successfully developed and implemented servo drives for two high-cavitation unscrewing molds for cleanroom applications. This technology enables a more effective arrangement of mold drive shafts, belts and pulleys.

“Servo-driven molds bring benefits to customers who are looking for efficient unscrewing mold designs that are more compact and suitable for cleanroom molding,” said Vince Travaglini, Vice President of Sales and Marketing at StackTeck. “Every customer I talk to is interested in the servo approach, and considering that it’s available at a very modest premium, we expect it will become the new standard for the industry.”

StackTeck’s servo-driven technology features a drive system that is encapsulated, making it well suited to cleanroom molding; a premium servo motor and control components from a leading global supplier; and improved energy efficiency compared to hydraulic rack-and-pinion systems. Additionally, mold maintenance requirements are significantly reduced due to the fact that it is a simple system with a single pendant and five buttons to control. The unscrewing speed is fast, accurate and controllable.

“In one case, a single-cavity prototype ran with conventional hydraulic technology with an unscrewing time of 1 second,” stated Jordan Robertson, General Manager of Business Development and Marketing. “However, when we ran the 16-cavity production mold, the unscrewing time was reduced to 0.3 seconds. That’s more than three times faster!”
