Our extensive range includes models suitable for both soft and stiff extrusion and most extruded sections eg: clay brick, hollow block, tile bats or sewer pipe at hourly capacities of between 5-80 tonnes per hour (green ware).

All Craven Fawcett worm sections are subjected to a combination of in-house treatments to ensure energy minimisation, longevity and component quality. After being cast, each worm section undergoes a unique heat treatment process in our own high temperature ovens in order to ensure an even distribution of chrome throughout the component.
