Plate Design for Synchronous Valve Pin Movement

Technoject Machinery, Bolton, Ontario, which is the North American distributor for Heitec Hot Runner Systems, Burgwald, Germany, has introduced Heitec’s type 64.086 Syncro Plate for valve-gate systems, which enables fully synchronous motion. Promising valve-pin positioning accuracy down to 0.01 mm, the system features flexible valve pin arrangement with any layout within the lifting plate. In terms of actuation, molders can choose between hydraulic or electric actuators to meet specific operational needs. From a monitoring and control perspective, the system features a 100% monitoring to ensure optimal performance and minimal downtime. Users can freely adjust various parameters, including forces, speeds and travel profiles to tailor the system to the specific production requirements.

The programmable warming and cut-out thresholds of the drive system can help prevent potential issues before they arise and, in terms of integration, the network between the drive controller, injection molding machine and temperature controller can prevent operator errors, including moving pins when the hot runner system is cold. The lifting plate promises backlash-free movements thanks to the helical gearing of the drive elements.

The hydraulic or electric actuators support a maximum lifting stroke of 32 mm, while the coated drive elements and built-in central lubrication prevent wear and make the system cleanroom compatible. During startup, the optimized calibration process features freely adjustable forces, speeds and travel profiles.
