EX101: THE ART AND SCIENCE OF EXTRUSION MACHINERY FOR WIRE AND CABLE

Instructor:
Dr. Stéphan Puissant, Process Manager, Maillefer SA, Switzerland

Description
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.

The high signaling and clock frequencies used in communications systems means that there are more sources of noise and distortion for modern electronics engineers to consider as part of their circuit design or measurement protocols. This course provides an introduction to Signal Integrity with a focus on the cable / connectivity industry.

The indicative content is:
• Time and frequency: bandwidth and spectra
• Shannon’s law, the evolution of coding schemes and inherent noise sensitivity
• Real components: understanding resistance, inductance and capacitance. Impedance and resonance
• Single ended and differential signaling: differential and common mode
• Ground and power planes are not perfect: switching noise, ground bounce
• Transmission lines in time and frequency. Lossy and lossless. Reflections, dispersion, eye diagrams, jitter, time domain reflectometry
• Crosstalk: Inductive and capacitive coupling
• Scattering parameters and de-embedding
• Vias
• Understanding limitations of measuring equipment (rise times and bandwidth of scopes, loading of probes, etc.)
• Application impact. Techniques used to manage the impact of noise in communications systems.

This course is suitable as a refresher for experienced professionals, but mostly as an essential overview for engineers within the first few years of working in this field and who want to develop an understanding of the essentials of Signal Integrity.
