K-Tron now offers plastics processors a gravimetric extrusion control package allowing the ability to control the extruder speed so that its output has a predictable and repeatable mass flow. By accurately measuring material throughput, gravimetric extrusion control can compensate for material and process variations and provide more consistent end product quality. (read more)

Different gas spring rod and body combinations are used when the K-Factor has to be lower or higher than standard (e.g., a lower or higher difference between the fully extended and fully compressed forces). (read more)

A constant force spring is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling. The force is constant because the change in the radius of curvature is constant. This is true if the change in coil diameter due to buildup is disregarded. (read more)

The K-Tron Feeder Group now offers the K-Tron Tablet Press Lubricant Feeder. An adaptation of K-Tron's sanitary pharmaceutical design twin-screw feeder, the tablet press lubricant feeder features the addition of a specialized gas venturi for aspiration of the lubricant (such as magnesium stearate) directly to the tablet press.
