The SPE Library contains thousands of papers, presentations, journal briefs and recorded webinars from the best minds in the Plastics Industry. Spanning almost two decades, this collection of published research and development work in polymer science and plastics technology is a wealth of knowledge and information for anyone involved in plastics.
The SPE Library is just one of the great benefits of being an SPE member! Are you taking advantage of all of your SPE Benefits?
in the Beginning - Initial Meeting: • Highlight major design objectives • Review possible product configurations • Define major product requirements • Review schedule • Investment & cost • Discuss marketing objectives. Current Products – vacuum formed & sheet metal construction
Regulations can be found in all industries: Automotive, Small Off Road Engine (SORE), Marine, Large Spark, etc. This presentation will focus on fuel tanks for the Small Off Road Engine (SORE) Industry. So what is a Small Off Road Engine (SORE) Application?
Copolymers of Nylon 6 - Benefits: • Good Gasoline Permeability • Long Term Heat Stability • Great Design Flexibility • Good VOC Behavior. Nylon 669: • Excellent Resistance to Hydraulic Fluid • Higher Wear Resistance • Extruded Monofilament • Much Lower Costs than High Number Nylons.
Why Polyethylene? • It is easy to mold. • It is widely available in rotomolding grades. • It has good physical properties. • Cost – offers a cost competitive solution to end users. • Knowledge and Confidence - molders are very familiar with it. • Market Identification – end users know rotomolding is a Polyethylene based industry and therefore design products to suit the capabilities of the material.
Teknor Apex Company Capsule: • Founded 1924 • Privately held company, for long term growth and stability • Fully equity financed • Worldwide production, marketing, sales, R&D • Continuous growth through re-investment of profits • Employing ~2,200 staff • Acquired DSM Sarlink TPVs November 2010 • Acquired Viking Polymers rigid PVC February 2014 • Acquired PTS April 2016
Threaded Inserts: • “How strong is this insert?” • “What is the Torque Strength of this insert?” • Mechanical bond between insert & substrate • Typically Threaded for secure attachment of bolts and fittings • Failure is dictated by their ultimate function!
Process Management & Control: • Classic Temperature & Control • Temperature Profile & Layer Maturation • Process Management System • Process Temperature Profile via Batch Instrumentation • Process Temperature Control via Non-Contact Instrumentation
How does craft beer relate to our industry? • Companies have the same equipment, but use it differently based on the products that their customer’s demand. • Both industries are very open and collaborative. People freely share their operational ideas and innovations. • Key characteristics are closely monitored in both industries. • Particle size distribution matters. It causes molding issues in roto, and prevents you from getting your grist into the mash in brewing. • The operational set-ups are dependent on product mix. • Both processes are hot and physically demanding. • Both industries have a limited number of raw materials, and it’s up to the designer to use those to create different and wonderful products. • Both industries have to innovate to succeed.
Presentation Outline: • Brief Overview of Solvay • The Need for UV Protection of Plastics • Definition of UV Rating for Rotational Molding • UV Ratings in North America and Europe • Correlating UV Rating with Expected Service Life • Primary Weathering Factors • Correlating Accelerated Testing to Outdoor Exposure • Polymer Testing for UV Rating • Other Considerations for the Rotational Molding Market • Out of Mold Color, Gas Fade, Processing Window, and Cycle Time • Summary

When designing plastic parts that are to be 3D printed, the designer must consider certain unique characteristics of the plastic printing process. These characteristics imply that different techniques must be used during design of 3D printed plastic parts than what might be used during design of injection molded plastic parts and design of 3D printed metal parts. This session will discuss some of the unique aspects of designing plastic parts for 3D printing as well as unique aspects of the preparation for printing these parts.
Cellulose nanocrystal (CNC) thermoplastic urethane (TPU) nanocomposites offer a wide range of unique thermal and mechanical properties. This paper focuses on solution mixing and melt processing considerations for producing cellulose nanocrystal (CNC) thermoplastic urethane nanocomposite filaments which can subsequently be printed using a fused filament fabrication (FFF) machine.
The case study will provide the roadmap as to how HP’s MJF technology will be used to manufacture components for manufacturing. This case study will go through the different phases of the process that enabled 3d Printed content for the next series of MJF 3d Printers. Including the steps of Assessment, Design, Economics, and manufacturing.
Multi Jet Fusion is new to the additive manufacturing industry, but the capabilities enable the process to be used in the manufacture of production quality components. This technical session will present a deep dive into the technology and illustrate how it achieves the value proposition and how to unlock value with the technology. Additionally, applications that are enables by Multi Jet Fusion will be discussed.
