EX101: THE ART AND SCIENCE OF EXTRUSION MACHINERY FOR WIRE AND CABLE
Dr. Stéphan Puissant, Process Manager, Maillefer SA, Switzerland
The complete extrusion process is complex and involves a lot of machines having each a different function. The heart of the process being extrusion, we focus in this course on the extrusion group, i.e. extruder and cross head (distributor and tooling).
The single screw extruder seems to be a very simple machine. However, the extrusion process is complex as it is governed by interacting laws from different mechanical engineering fields i.e., thermodynamics, flow mechanics, properties of solid and molten polymers etc. Therefore, in a first step, the physical characteristics (viscosity, conductivity, melting) of polymers used in extrusion are presented. These properties will be the keys to understand the functioning of the thermoplastics extrusion process.
The material basis being covered, the focus will shift on the functioning of the single screw extruder. There the 3 functional zones of the extruder are introduced. For each zone, we will see its functioning in relation to material properties. This mechanism having been described, we will obtain some hints of the optimal screw designs (for some broader plastic families!), so as solutions which may be used to solve problematic issues.
After being plastified (molten), the polymer will be formed in its final shape by some extrusion head. In this part of the course, the basics of distributor design according to the materials are presented. After discussing the effects of distributor geometries, we will also compare different tool designs. And the influence of temperature settings on concentricity, adhesion and surface quality will be shown.
For each of the different items (extruder, X-head, even cooling) evoked in the course, we will try to give some practical hints in relation with a more theoretical approach.
This course is intended for people involved in extrusion and who want a basic analysis tool for identifying potential machinery bottlenecks due to the extrusion group, so as to solve some issues which are hampering the productivity and quality.

FO209: THE RELIABILITY OF OPTICAL FIBERS AND PASSIVE FIBER COMPONENTS IN LONG AND SHORT COMMUNICATION NETWORKS
Tarja Volotinen, Expert, Tarja’s Consulting AB, Hudiksvall, Sweden
The mechanical and optical reliability during the past over 35 years in service are overviewed for optical fibers, splices and passive fiber components. The failure mechanisms that are possible in fibers, and also the methods how they can be decreased or avoided in the networks are presented.
The reliability requirements and survival estimates for communications links, ranging from the thousands of kilometers overseas connections to the short, a-few-meters – hundreds-of-meters datacenter and cloud networks are described. The physical and chemical conditions that the fiber materials and cable structures need to withstand are also described.
The lifetime calculation method (IEC TR62048) and the test methods (according to the relevant FOTPs, IEC and other standards) to characterize the mechanical properties of the fibers and components are described in detail. Special care is used to understand the strength of the high strength parts and weak spots of optical fibers, and how the test data needs to be analyzed for the lifetime and failure rate estimation in different networks and service environments (chemical and physical).
Furthermore, this course also presents the optical and mechanical worst case failure modes (e.g. attenuation increase, hydrogen aging and fiber glass surface corrosion etc.) that might occur in the case unsuitable materials and manufacturing methods are used. Finally, the typical reliability of fibers in appropriate cable networks, which now provide us all the broad band communication worldwide are presented. – The course is based on the literature data.
This course is designed for engineers of manufacturers, network and system designers and operators.
