Design and engineering for the quality and efficiency of high-volume, low moisture stiff extrusion

Steele extruder designs include hydraulic die changers
and hinged mouthpieces, for quick changes and cleaning. 
Dies can be adjusted during extruder operation. 
Augers, gears, bearings, shafts, clutches and sheaves
offer long service life and easy service.

Our global leadership in stiff extrusion is built on decades of experience, originating with our hand-in-hand relationship with the U.S. brick industry.  As American manufacturers searched for improvements to the European tradition of soft extrusion, they recognized the superior efficiency of stiff extrusion and direct setting.

As the industry evolved, J.C. Steele worked to develop machinery with the strength and durability to serve its needs.  Today, more than 90% of the clay bricks manufactured in the U.S. are made with Steele machinery.  The economy and performance advantages of stiff extrusion equipment are well established in clay working, as well as resource recovery and waste management in a wide range of plastic and non-plastic materials.

Extrusion equipment that eliminates the cost of adding and removing water

J.C. Steele extrusion technology is ideal for a wide range of brick, block and tile with void areas up to 65%.  It yields superior strength and structural integrity in the “green” manufacturing state and, in many cases, a fired product that maintains truer dimensions and surfaces in its finished state.  Our stiff extrusion technologies use high torque and high pressure to produce penetrometer readings as high as 4.0-4.5 kg/cm².  Steele machinery can typically be used to extrude materials with less than 20% moisture.  Because stiff extrusion doesn’t require high levels of plasticity, Steele stiff extrusion systems are usually less expensive to own and operate than comparable technologies.

This ability to work with a wide range of plastic and non-plastic materials, coupled with minimal water addition, makes Steele stiff extrusion equipment a superior investment—our extruder designs offer a high level of agglomerated output, with lower capital and operating costs for a better return.
