Micro-Mini II™: The Next Generation In Small Extrusion Tooling Is Available Today

West Warwick, RI – Guill Tool & Engineering has introduced the Micro-Mini II™ extrusion tooling, a considerably more compact version, for even smaller applications, than its highly popular Micro-Mini™ extrusion tooling. This new model has all of the advantages of the original version, but with the advantage of producing significantly smaller products than its predecessor, and because of its smaller size is also easier to handle.


The Micro-Mini II™ is available in crossheads/inline dies to extrude product with an O.D. of 0.005 – 0.100 of an inch, as well as creating highly accurate walls of up to .0002” (0.0050 mm). The Micro-Mini II™ has overall dimensions of 1.772” (45mm) in diameter by 1.772” (45mm) in length, smaller than the Micro-Mini™, which measures 2.36” (59mm) in diameter by 2.36” (59mm) in overall length.


Specially engineered for manufacturers of medical tubing, wire and cable, electronics and tiny specialty OEM applications, the Micro-Mini II™ provides an exacting, convenient method to create the tiniest micro-sized tubing to date, with all types of compounds and expensive resin and polymer combinations. Applications are especially useful for those advanced medical projects that require tubing walls much smaller than the human hair.


The Micro-Mini™ Series is available in single layer, single layer with a stripe, co-extrusion, co-extrusion with a stripe, triple extrusion and triple extrusion with a stripe, and in unlimited custom configurations.


“It is important to note that when considering tooling, we are only restricted in how small we can go by the capabilities of the downstream process equipment that has to be utilized in these types of mini applications,” said Bill Conley, Guill Tool Sales Manager. “Yet, today at Guill, we have the technology to go even smaller in size than our Micro-Mini II™ extrusion tooling. It’s up to the process equipment companies to readily accept this challenge and develop equipment for this growing, smaller market of tiny micro products.”


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 easy self-alignment, thereby reducing potential errors during assembly.

The Micro-Mini II™ 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 a fixed center or adjustable center. Mica-band heaters are instrumental in safeguarding and enhancing the material temperature for the optimum flow of the extrusion end product.


Guill Tool also manufactures tips, dies, and breaker plates using state-of-the-art computerized CNC machining and EDM equipment. As well, engineering services using the latest CAD systems are available for custom-designing extrusion tooling products such as crossheads, tips, clamps, flanges, forming rolls, spiderless inline dies, swing gates, breaker plates, and sizing dies. Guill Tool received ISO certification in 1995, the first major extrusion tooling company to meet international standards.


The company has long been recognized as one of the leading established designers and manufacturers of custom extrusion tooling for all types of applications including: wire, cable, fiber optics, medical tube, wood composites, automotive tube, plastics compounding, custom applications, rubber, profile, industrial pipe, hose & tube, blow molding, food and packaging.  Guill Tool encourages and provides education and training for the extrusion industry by using models of plastic and aluminum heads for training, fully illustrated operating manuals for step-by-step assembly and disassembly, training videotapes, and classes on the care and cleaning of extrusion tooling.


Founded in Rhode Island in 1962 by A. Roger Guillemette, Guill Tool was established as a job shop supplying tips, dies, crossheads and replacement parts to the wire, cable, plastic and rubber industries in New England. Later, Guill Tool became a supplier for the entire United States and Canada, and today enjoys a worldwide market presence.
