The MicroFlow spiral, a low-volume stainless steel crosshead designed for multilayered, thin-wall extrusion, is reportedly adaptable to all extruders. It's suitable for OEM and medical fluoropolymers as well as thermoplastics extrusion manufacturers. A balance flow design offers easy assembly and disassembly of the crosshead.
The crosshead has an adjustment in the die holder, and a cartridge-style ball assembly that doesn't require the loosening of retaining screws to make adjustments. It also has a system that eliminates leakage between the deflectors and is maintained through self adjustments, thereby reducing potential errors during assembly. The spiral model is available in three standard designs?single, double, and triple extrusion capabilities?and for custom designs up to five layers.
The spiral is adaptable to all extruders and is manufactured in stainless steel to meet the requirements of medical and other FDA-type applications. A balance flow design offers easy assembly and disassembly of the crossheads. The spiral core diameter is .375 inch and the maximum product size is .5 inch. The inner layer includes a fixed center and the outer layer's adjustable concentricity function uses retaining screws.
The gum space adjustment operates via rotation of the core tube. Quick-change tooling is said to ensure easy removal of the tip from the back and the die from the front.
