• Discuss future Webinars

Discussion items

Presentations:

• Welding Options for Coil Joining Tin Plate

  • By Deni Bellai of Miebach

    • Welding is a common method for joining Tin Plate for joining coils that will run through a continuous operation.  Within the welding options there are two methods in common use.  The coils can be joined using resistance welding or laser welding. The presentation will review both these technologies and provide some information useful in deciding which method would be most suitable for a given application.

• MSA – Tin Plating with the Best Choice of Electrolyte

  • By Brian Prybell of Quaker Houghton

    • This presentation will discuss the history of MSA in commercial tinplating touching on initial issues encountered upon market introduction and decades of continuous improvement to the electrolyte and associated plating constituents.  It will also develop the benefits MSA plating has over all other forms of electrolyte (PSA/Halogen) including cost, environmental, exposure, quality, and operating parameters.  Hassle less conversion to MSA in both time lost and capital investment are elements that will also be introduced.  MSA electrolyte is in use across 50% of the global tinning lines and interest continues to grow for economic and environmental reasons; there is no other second best choice.

• Unique Non-Woven Fabric Rolls: A Technical Overview of Strengths & Weaknesses Description

  • By Eric Almquist of Star Tool & Die

    • Process roll coverings can be assigned to three (3) surface types: rigid, deformable, & compressible.  Non-woven fabric coverings are uniquely compressible because they are uniquely porous.  The porous construction is the root of the roll covers’ strengths and weaknesses relative to more standard roll covers and surfaces.  A practically focused technical presentation can be configured to explain the four (4) typical advantages and three (3) possible disadvantages of non-woven rolls for sheet processing, including use-case overview for all lines of tin plate process, and/or including how non-woven rolls are made, and/or the factors that affect non-woven material performance, and/or details of maintaining non-woven rolls.

• World Class Safety Culture – Steelscape - Kalama

  • By Chris Carlson of Steelscape - Kalama

    • This presentation will describe Steelscape’s high performance organization that motivates people to contribute their strengths, talents and abilities to meet both individual and team needs and inspires people to attain their highest levels of performance

• Defects on Tinplate and Analysis Methods

  • By Li Sun of ArcelorMittal Dofasco

    • The presentation will include the followings:

• Introduction of the instruments in Hamilton lab and their general usage.

• Defect analysis procedures

• The common defects on tinplate products

• Examples of tinplate material characterization and defects observed from production lines and the analysis methods.

• Examples of defects on can products and analysis methods.

• Tin Code and our Sustainability initiatives in support of the global tin industry

  • By Mayra Díaz del Olmo Oliveira of International Tin Association Ltd

    • As the spotlight on responsible and sustainable mineral sourcing is increasing, we take a look at what this means for companies – and how to leverage tin supplier information and tools to manage risks, increase credibility, and drive improvements for people and the environment.
