Boltless Flat Die Opens Faster
Without changing the inner workings of the die, Extrusion Dies Inc., Chippewa Falls, Wis., has come up with a revolutionary way to assemble flat dies without bolts. The closing mechanism replaces conventional die bolts with rods actuated by hydraulic toggles to hold the die halves together.

How to Get 50% Higher Output Of Large PVC Profiles
With the right combination of die and cooling technologies, there’s no reason why extruders of large, complex PVC profiles cannot get up to 50% faster throughput than they are now used to.
Read MoreDie Drawing Makes ‘Plastic Steel’From Wood-Filled PP
A developer of new plastics technologies is applying low-temperature die drawing to take advantage of a new raw material: expanded, oriented, wood-filled polypropylene (EOW-PP).

NPE will show higher outputs of practically everything, as advances in grooved feeds, servo drives, screw torque, mixing screws, dies, and downstream cooling, cutting, and handling make everything run faster. Running faster in turn requires a higher level of control, or you can just make a whole lot more bad product faster.
