Guill Tool & Engineering: Medical Extrusion Tooling
A new ultra-low volume crosshead design for multi-layered, thin-wall extrusion accuracy is now available from Guill Tool & Engineering, based in the US. It is applicable for OEM and medical fluoropolymers and can be utilised by thermoplastics extrusion manufacturers. The new MicroFlow spiral crosshead’s engineering advantages include a patent-pending Feathertouch adjustment in the die holder, plus a cartridge-style ball assembly that does not require the loosening of retaining screws to make adjustments. It also has the Seal Right System, which eliminates leakage between the deflectors and is maintained through easy self-adjustments, reducing potential errors during assembly. This MicroFlow spiral model is available in three standard designs — single, double and triple extrusion capabilities. The MicroFlow spiral is fully adaptable to all extruders and is manufactured in stainless steel. A balance flow design offers easy assembly and disassembly of the crossheads. The MicroFlow spiral core size 9.5 mm and the maximum product size is 12.7 mm. The inner layer includes a fixed centre and the outer layer’s adjustable concentricity function utilises retaining screws.
