Extrusion

Our extrusion capabilities are extensive, ranging from single lumen tubing to coextrusions and multi-lumen tubing with up to 22 lumens and more possible. Extruded profiles are limited only by your imagination, plus some laws of physics. Wire or thread offers added strength, kink or stretch resistance, electrical conductivity or other characteristics if your design requires. Additional equipment includes multiple-axis laser micrometers and on-line cut-to-length machinery.

The Extrusion Process

The extrusion process begins with the blending of a two-part gumstock (catalyst and crosslinker) on a two-roll mill. The blending process yields a homogeneous compound that is formed into strips and fed continuously into the extruder. A variable speed screw feed is used to maintain proper pressure at the pin and die.

During the extrusion process, dual-axis laser micrometer checks are performed to help ensure proper dimensional control. Once extruded, the tubing passes through vulcanization ovens (HAVs), where heated air or radiant heat cures the product.
