FTIR Made Easy for Better Identification of Plastics

August 29, 2019, 9 AM CST
Presenter: Jeffrey Jansen

Fourier transform infrared spectroscopy (FTIR) is a powerful analytical technique for the development of polymer materials. Mastering FTIR can not only enable you to characterize materials (through changes in molecular structures) but also ease problem solving and minimize failures.

Understanding Plastic Failure Rate

September 12, 2019
Presenters: Jeffrey Jansen

When a plastic part fails, a tough question is often asked, "Why are a limited number of parts failing?". This is particularly true with seemingly random failures at significant, but low, failure rates. Two aspects are generally linked to such low failure rates, multiple factor concurrency and the statistical nature of plastic failures. Failure often only takes place when two or more factors take effect concurrently. Absent one of these factors, failure will not occur. Plastic resins and the associated forming processes produce parts with a statistical distribution of performance properties, such as strength and ductility. Likewise, environmental conditions, including stress and temperature, to which the resin is exposed through its life cycle is also a statistical distribution. Failure occurs when a portion of the distribution of stress on the parts exceeds a portion of the distribution of strength of the parts. This webinar will illustrate how the combination of multiple factor concurrency and the inherent statistical nature of plastic materials can result in seemingly random failures.

Understanding Structure-Property Relationship for Effective Polymer Selection

October 9, 2019, 9 AM CST
Presenter: Jeffrey Jansen

Being increasingly used in demanding applications, plastic materials often have to endure aggressive chemical contact, elevated temperature exposure and demanding mechanical stresses. Choosing the right material in these applications is critical to avoid part failure! But often, limited understanding of the interrelationship between molecular structure and properties acts as a roadblock

Degradation Failure of Plastics

October 10, 2019
Presenters: Jeffrey Jansen

Plastic materials offer a unique balance of strength and ductility associated with their inherent viscoelastic nature. However, they are susceptible to molecular degradation through a variety of exposures. Molecular degradation is a permanent change in molecular weight that reduces the mechanical properties and integrity of the plastic material. This degradation can occur during compounding, processing, storage, or while in service.

The various forms of molecular degradation account for approximately 20% of plastic part failure, and an understanding of the nature of degradation can help to prevent failure. Topics covered during this session will include:

Plastic Part Failure: Analysis, Design & Prevention (UW-Milwaukee at Milwaukee)

October 14-16, 2019
Presenters: Jeffrey Jansen, Dr. Antoine Rios, Dr. Javier Cruz, and Erik Foltz

Dive into a broad range of topics essential to understanding and preventing plastic failure. The most efficient and effective approach to plastic component failure is performing a systematic failure analysis following a scientific method. Someone once said, "if you don't know how something broke, you can't fix it," highlighting the importance of a thorough understanding of how and why a product has failed. With emphasis on practical problem-solving techniques, the course will utilitze case studies to comprehend key aspects of plastic failure and prevention. Gain a better understanding of why plastic components fail, and how to avoid future failures by applying the knowledge learned.

Dynamic Mechanical Analysis Webinar Through SPE

June 13, 2019
Presenters: Jeffrey Jansen

Dynamic Mechanical Analysis (DMA) is a thermoanalytical technique that measures the stiffness (modulus) and damping (tan delta) of polymeric materials to assess the viscoelastic properties as a function of time, temperature, and frequency. Polymeric materials display both elastic and viscous behavior simultaneously, and DMA can separate these responses. Polymers, composed of long molecular chains, have unique viscoelastic properties, which combine the characteristics of elastic solids and Newtonian fluids.

DMA is a very powerful tool for the analysis of plastics and can provide information regarding:

Creep Failure of Plastics

February 14, 2019, 10 AM CDT
Presenter: Jeffrey Jansen

Creep is the tendency of a polymeric material to deform permanently under the influence of constant stress, as applied through tensile, compressive, shear, or flexural loading. It occurs as a function of time through extended exposure to levels of stress that are below the yield strength of the material. Given sufficient time, this can lead to creep rupture, the failure within a material as a result of continuously applied stress at a level below the short-term tensile strength. Plastic materials are particularly prone to creep rupture through exposure to static stresses, and a recent study indicates that 22% of plastic failures are associated with creep.

The relatively high frequency of creep failure is linked to the widespread lack of awareness and understanding of the effects of time on polymeric materials, particularly at the design stage; the unique difference in time dependence between polymeric materials and metals; and the increasing use of plastic materials in diverse applications with longer time demands.

The concept of creep is extremely important to manufacturers and designers of plastic components.

How Cooling Line and Mold Design Influence Plastic Part Cost and Performance

January 9, 2018, 10 AM CDT
Presenter: Erik Foltz

Cycle time optimization is often one of the main objectives when designing and constructing the mold. However, the majority of a molding cycle is often dictated by the cooling time. Therefore, it is strange that in the mold design process the integration and design of the cooling line layout and high conductivity inserts is often left toward the end of the design process where the design envelops has been drastically reduced. It is also commonly believed that the placement of the cooling lines is the only driver for properly cooling the part, and its design only influences the manufacturability of the part. This presentation will highlight the importance of all aspects of the mold cooling design on molding efficiency, and will also highlight how decisions on this design aspect of your mold actually influence the end performance of your plastic part. These points will be illustrated through practical engineer calculations and validated through case studies.
