Extrusion Asia Edition 1-2025

22 EXTRUSION & RECYCLING ASIA 1/2025 挤压工具 D rain tubes can be inserted prophylactically to prevent or remove the accumulation of fluid in a wound. Alternatively, such tubing can also be therapeutically inserted to evacuate an existing collection of uid in a wound. Fluid is removed in order to treat or prevent infection and promote wound healing and patient comfort. Drain tubes can also be used to diagnose post-operative complications such as an anastomotic leak or hemorrhage. The Guill design has unique features that eliminate the need to weld or otherwise join sections with di erent pro les together. “Our automated extrusion process drastically changes the extruded pro le in production, with no need to join sepa - rate sections of internal pro les,” comments Tom Baldock, Sales Manager, Guill Tool Guill has engineered this new reciprocal tubing die with various features, unique to the product. The traditional tip and die assembly is replaced with a linear reciprocating as - sembly that changes the tube’s pro le within a given length. This process is repeated throughout a single extrusion run without interruption. Cutting capability, in association with the extrusion speed, cuts the nished product to length. While cost and value stream activities are reduced, qual - ity is actually improved. Only one extrusion run is needed to produce a nished product, as opposed to multiple extru - sion runs with tooling changes along with a manual assem - bly operation to connect di erent tubing shapes via sonic welds or other methods of joining. Guill’s new reciprocat - ing head eliminates this entire assembly operation. It also eliminates in-process inventory. Thus, there is no need for storage of various tubing shapes and connectors needed for assembly, ful llment of orders and replenishment of n - ished goods. Furthermore, the reciprocating head eliminates a con - necting piece, allows JIT production and products made- to-order. Lastly, it reduces total run time from receiving the order to shipping product. In the multi-layer extrusion arena, a primary focus of Guill Tool over the years, the company has also introduced the latest generation of its Series 800, the 2-to-6 layer extrusion tooling designed to produce the highest quality, highest ma - terial-e cient 1/8” to 6” OD tubing for medical and surgical applications. The redesigned Series 800 produces awless - ly smooth extrusion and layer de nition of Fluoropolymer and other materials for all multi-layer, multi-lumen medical tubing. The Guill design further allows thin layer combina - tions of polymers and adhesives to .02mm or less. Guill o ers its extensive line of crossheads and inline tubing dies in xed and adjustable center, for single or co- extrusion applications. The tooling is designed to process all compounds and features the company’s patented, pre - cision Feather Touch Concentricity adjustment, the Seal Right System, which combines with the Feather Touch sys - tem to eliminate polymer leaking. Guill also o ers its unique spiral ow distribution system. All Guill tooling is produced with rigorous computer simu - lation of the ow channels using Computational Fluid Dy - namics (CFD) programs, resulting in optimum uniform ow with no weld lines. Finally, the new Series 900 of inline tubing dies from Guill Tool & Engineering Co., Inc. o ers improved extrusion per - formance and capabilities to customize at standard, o -the- shelf prices. The new series is applicable to extrusion of hose or pipe ranging from 0.005″ (0.127mm) to 8.0″ (635mm) in diameter for all types of OEM, food service, automotive, industrial, telecom and medical applications in polymer or rubber. The Series 900 technology o ers these key bene ts: • Achieves concentricity or “product roundness” which greatly reduces material usage compared with other types of extrusion tooling Guill Series 800
