National Hands-On Thermoforming Workshops
Heavy-Gauge/Cut-Sheet Thermoforming Workshop
START DATE & TIME:
- Tues., May 12, 8:30 a.m.
Topics include advances in raw materials and sheet extrusion; heating and cooling the sheet; and forming, trimming, and handling the part. Advanced session on raw materials; reheological properties; specialty sheet; part, mold, and plug-assist design; heating technology; advanced forming techniques; trimming technology, assembly methods; and diagnostic tools. Hands-on sessions include thermoforming process techniques and troubleshooting, materials testing, and sheet extrusion basics. Jay Waddell and special guest speakers to be announced. PLEASE WAIT TO BOOK YOUR FLIGHT UNTIL YOU RECEIVE CONFIRMATION THAT MINIMUM ENROLLMENT HAS BEEN MET. You can receive a $100 discount if you are a SPE Thermoforming Division Member (you can join 4SPE.org and use code PCW-15 for $99 rate rather than $144). SPE Membership must be for the person registering and note in comments section when registering for class (e-mail needed for confirmation).
Thin-Gauge/Roll-Fed Thermoforming Workshop
START DATE & TIME:
- Tues., June 23, 8:30 a.m.
Topics include advances in raw materials and sheet extrusion; heating and cooling the sheet; and forming, trimming, and downstream handling of the part. Advanced session on raw materials; rheological properties; specialty sheet; part, mold, and plug-assist design; heating technology; and diagnostic tools. Hands-on sessions include thermoforming process techniques and troubleshooting, materials testing; and sheet extrusion basics. Mark Strchan and special guest speakers to be announced. Please wait to book flight until you receive confirmation that minimum enrollment has been met.
