The adoption of SolidWorks has also allowed World Kitchen to eliminate its reliance on outside design contractors, which generates additional cost savings. Finding this thermal balance produces high-quality glass and prevents the glass from melting the metal molding components that we use in manufacturing.” “This is why it is so important to have accurate water flow and cooling. If the forming equipment is too hot, the glass will fuse itself to the metal, making it impossible to remove from the mold,” Cooley explains. “If the forming equipment is too cool, the glass will have a wrinkled appearance.
This thermoforming process runs 24 hours a day, seven days a week, at speeds of 20 to 50 pieces per minute, depending on product size.Īccording to Senior Mold Designer Mark Cooley, using 2-D techniques required a cumbersome trial-and-error process to achieve the optimal thermal balance and smooth production runs. At a temperature of 1150☌, molten glass flows around bends before it falls into a mold, where a press forms the glass into various bakeware shapes. Until 2006, the Pyrex plant used 2-D design tools to develop its products in conjunction with a trial-and-error approach to its thermoforming manufacturing process. The company also manufactures other well-known brands of dinnerware, cookware, cutlery and household tools-including CorningWare®, Corelle®, Revere®, EKCO®, Baker’s Secret®, Magnalite®, Chicago Cutlery®, OLFA® and OLO®. World Kitchen, LLC, produces its tempered, heat-resistant Pyrex bakeware in a facility that has manufactured glass products since 1889.
