Guill Tool & Engineering recently unveiled its Micro-Mini II extrusion tooling — a compact version of the popular Micro-Mini extrusion tooling — intended for micro applications, and for use with all types of compounds and expensive resin and polymer combinations.

Available in single layer, single layer with a stripe, co-extrusion, co-extrusion with a stripe, triple extrusion and triple extrusion with a stripe, the Micro-Mini II is specially engineered for manufacturers of medical tubing, wire and cable, electronics and tiny specialty OEM applications. The tooling is particularly well suited for advanced medical projects requiring uniform tubing walls smaller than a human hair.

This new model has all of the advantages of the original version, the company said, but with the additional benefits of producing significantly smaller products than its predecessor and offering increased ease of use.

The Micro-Mini II is available in crossheads/inline dies to extrude product with an O. D. of 0.005 to 0.100 inches, as well as creating highly accurate walls of up to .0002 inches (0.0050 mm). The unit has overall dimensions of 1.772 inches (45 mm) in diameter by 1.772 inches (45 mm) in length.

The Micro-Mini II’s new die/crosshead engineering advantages include a patented FeatherTouch adjustment in the die holder, which 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 self-alignment, which reduces potential errors during assembly.

The die/crosshead series is fully adaptable to extruders one inch in diameter and smaller, and is manufactured in stainless steel or Inconel to meet the requirements of medical and other FDA-approved applications. The Taperlock design offers effortless assembly and disassembly of the crossheads. The tooling is available with either a fixed or an adjustable centre. Mica-band heaters safeguard and enhance the material temperature for the optimum flow of the extrusion end product.
