Masterbatch for miniaturisation of fibre optic cables Smaller cable diameters are a key factor in reducing the cost of occupancy in installation conduits. In this context, a reduction in fibre optic cable tube diameter leads to a significant reduction in wall thickness. While this change implies greater transparency of the plastic material, it also poses challenges in the colouring of these components. The identifying function of the colours on fibre optic cable tubes is compromised by excessive transparency, distorting the original colours and making accurate identification difficult for installers. with Delta Tecnic to adapt to the new technical requirements generated by the miniaturisation of cables. This collaboration has resulted in an efficient masterbatch capable of maintaining the colour identification of tubes with reduced thicknesses. Jordi Pérez, Optral’s deputy director of operations, said “The quality of a fibre optic cable also lies in making Delta Tecnic has introduced a masterbatch that assists the miniaturisation of fibre optic cables

reduction in dosage of more than 25 per cent during the extrusion of minimised tubes, ensuring a balance between mechanical properties and material cost reduction. The innovation not only ensures consistency in cable properties, but also optimises the manufacturing process without sacrificing the quality of the final product.

corresponding cost savings. Typical applications for rotary heads include medical and multi-lumen tubing, and various high-end extrusions with interlocking layer or multiple striping requirements. Features offered on the new rotating extrusion dies include counter-rotating tip and die; co-rotating tip and die; ro- tating die with conventional tip; rotating tip with conventional die; crosshead or in-line; and multi-layer, striping, certain profiles and optional quick-change cartridges that minimise cleaning downtime. By using rotary dies, extruders can eliminate secondary processes and achieve cosmetic enhancement of the end product (with no weld or parting lines), as well as reducing or completely eliminating ovality. Guill Tool offers its new high-speed rotary models as turnkey packages, com plete with die cart, tools and all accesso ries for installation and maintenance. Guill Tool & Engineering Co, Inc www.guill.com it easier for the installer to identify it correctly, and in the micro-cable environment this becomes much more demanding and critical. New high performance masterbatch developments such as those provided by Delta Tecnic are necessary for the continuous improvement of our products and applications.” Delta Tecnic’s expertise enables the dispersal of large amounts of pigments, reducing masterbatch dosages while increasing tube opacity. These types of masterbatch allow for a claimed

Delta Tecnic has used its experience in manufacturing masterbatch and additives for cables to develop solutions to address this emerging issue. Its specialised masterbatch offers precise opacity and colouring functionality, ensuring that fibre optic cable tubes maintain their original visual identification, even at minimum thicknesses of 0.1 to 0.2mm.

New rotary in-line or crosshead dies at 1,000 rpm Extrusion tooling technology specialist Guill Tool has introduced a new design for its high-production rotary models, both in-line and crosshead style.

Models rpm, depending on the application, are now available in the Guill line of patented rotating tip and die designs. By rotating the tooling in relation to the material flow, a rotary head increases the wall strength of an extrusion, allowing a thinner wall with less material, and running to 1,000
