Advances in Porcelain Enameling

The 2002 PEI Technical Forum will highlight new developments in porcelain enamel formulations and application techniques, as well as practical tips for day-to-day operations.

Porcelain enamel suppliers and end users from around the world will gather in Cincinnati, Ohio, May 13-16, for the 2002 PEI Technical Forum, hosted by the Porcelain Enamel Institute (PEI). The forum will include a small exhibition, called the Suppliers Mart, as well as more than 30 presentations on a variety of technical issues, such as fabrication and metal preparation, laboratory investigations, porcelain enamel markets, processing methods, application and quality control equipment, and the industry as a whole.

“We cover everything from the metal to the finished product in the Technical Forum,” says Cullen Hackler, PEI’s executive vice president. “The content varies every year, but it always highlights new things that are being done or advances that the suppliers are investigating in their laboratories.”

The forum will also include training workshops on both porcelain enameling and powder paint. Following is a brief overview of what Technical Forum attendees can expect to find at this year’s meeting.

Educating the Industry

The 2002 Technical Forum will open with the Suppliers Mart exhibits and a reception on Monday, May 13. Attendees will have a chance to speak directly with the exhibiting companies and network with others in the industry. The Suppliers Mart will be open every evening from 5 to 7:30 p.m.

On Tuesday, two workshops will be held concurrently throughout the day. The Back to Basics Workshop, chaired by Holger Evele of Ferro Corp. and Tony Mazzuca of Pemco Corp., will cover the fundamentals of porcelain enameling, including substrates and selection, fabrication, metal preparation, porcelain enamel frits, wet and electrostatic powder application methods, drying and firing, defect analysis, and troubleshooting. The Powder Paint Workshop, chaired by Ken Kreeger of Nordson Corp., will cover powder materials, pretreatment systems, powder application equipment, powder spray booths, the basics of electrostatics, system efficiency and maintenance, curing, and troubleshooting.

Promoting Technological Advances

The Technical Forum will convene on Wednesday, May 15, beginning with the A. I. Andrews Memorial Lecture on “Industrial Color Control,” presented by Dr. Ralph Stanziola, Industrial Color Technology, Red Bank, N.J.

A session on fabrication and metal preparation will include talks on a “Porcelain Enamel Checklist for Fabrication,” by Larry Steele, Mapes & Sprowl Steel; “Experiences with Hydroforming,” by Steve Champlin, Vitreous Steel Corp.; and “Economizing your Quality Porcelain Enamel Pretreatment Line,” by Ken Kaluzny, Coral Chemical Co.

A number of suppliers will also discuss laboratory investigations. Papers presented at this session will include “Impact of Ground Variation on Electrostatic Porcelain Enamel Powder Application,” by Holger Evele, Ferro Corp.; “A Standard Test Method for Measuring the Adherence of Porcelain Enamel Coatings to Sheet Metal,” by George Altemus, U.S. Steel; “The Effects of Rubidium on Selected Electrostatic Powder Properties,” by Steve Kilczewski, Pemco Corp.; and “Spindle Machine for Glaze Application,” by John Evans, Ferro Corp.

Other presentations will cover equipment used in the porcelain enamel industry, powder thickness measurement, principles of electrostatic powder, and various initiatives backed by PEI.

Plant Tours and Problem Solving

The Technical Forum will conclude on Thursday, May 16. That afternoon, attendees will have the opportunity to tour either A. K. Steel Corp. or A. O. Smith Corp. (Reservations are required.) Alternatively, attendees can participate in the Troubleshooting Seminar, moderated by Anthony Mazzuca, of Pemco Corp. Seminar participants will discuss the porcelain enameling process and many common problems, as well as practical solutions. Participants are encouraged to ask questions, bring samples and participate in the discussions.
