Thermoforming
Coextrusion Adds Shine to PP For Thermoforming Large Parts
New coextruded resin combinations are making polypropylene a contender for large thermoformed parts in outdoor uses from pleasure boats to automotive exterior trim.

As sheet extruders consolidate, they're modernizing operations to raise output and efficiency. The pressure is on to run faster, wider, with more layers and innovative combinations of materials. The challenges multiply as sheet extrusion is teamed with in-line compounding and downstream operations like thermoforming.

The buzz in thermoforming at K'98 was actually more like a hum--the sound of electric servo motors driving every motion of new or redesigned roll-fed machines. Greater speed and accuracy are said to result from the shift away from pneumatics and hydraulics, an evolution that was evident at the show in many different types of plastics machinery. A line of Dutch machines now sold in the U.S. also comes with servo drive.
