Wayne Machine & Die Co. of Totowa, N.J., said its Yellow Jacket vertical extruders have excellent balanced weight distribution to help prevent tip overs, a safety problem with vertical extruders.
Typically, Wayne Machine said, vertical extruders with in-line gearboxes have all the weight of the mechanical section on one side of the post. The Yellow Jacket positions the motor on the opposite side of the extrusion processing section for more balance.
This layout also allows the use of double-reduction helical gearboxes with shaved ground and hardened gears, instead of soft-gear or enveloping worm-type gearboxes.
The helical gearbox delivers more power to the screw, with less wasted energy converted into heat from friction.
Wayne Machine said processors now can coextrude engineering resins and high-fill materials, which require high levels of screw torque.
The single-post series comes in screw diameters of one-half inch, five-eighths inch, three-fourths inch, 1 inch, 1¼ and 1½ inches. Double-post machines come in 2-and 2½-inch sizes.
