Gear Pump Preformers and Extruders

Gearing up for increased business or have long production runs? A Gear Pump Preformer will provide you with a continuous production capability, reduce machine set-up and negate the need to pre-heat rubber on a two-roll mill.

Gear Pump Preformers and Extruders

Barwell Gear Pump Continuous Rubber Preformers

The Barwell Gear Pump Preformer is a fully automated and highly advanced screw extruder with gear pump technology, specifically designed to provide high levels of control and processing flexibility. The range is ideal for the preforming or extrusion of almost any form of rubber compound.

Excellent for long continuous production runs or for profile extrusion requiring greater dimensional stability.
Suitable for the production of rubber preforms/blanks, pellets, and also strips and cord extrusions
A fully automated processing method which reduces user dependence and increases productivity
Technologically advanced processing provides optimum levels of dimensional stability, product consistency, accuracy and superior quality
An intelligent process that ensures very high-temperature control providing versatility at low temperatures
Enables extrusion, cutting and check-weighing in one precise and efficient process
A cost-cutting solution reducing material wastage and labor costs as well as negating the need to pre-heat your rubber on a two-roll mill
A safe, reliable and user-friendly system
