Tire Re-treading Machines

A cost effective all-in-one direct to casing process

PressurBuilder: Tire-retreading


The Barwell PressurBuilder is a unique and fully automated tire re-treading system with integral in-line screw extruder. It is designed specifically to provide a high quality and cost effective method of recycling truck tires.

The hot rubber is extruded, under pressure, in one accurate profile directly onto the buffed casing as the casing rotates through one complete revolution.

The method brings the buffed casing directly into the head of the extruder and forms on half of the die profile.
