Servo controls for a new hot-plate welder are said to provide twice the speed of pneumatic and hydraulic units. Model HPW1015 from Extol Inc., Zeeland, Mich., is the first standard product in the company’s formerly all-custom hot-plate line. The three-axis model has a 1 x 15 in. weld area, 6-sec cycle time, 15-in. platen opening distance, and maximum plate temperature of 800 F. Target applications include brake reservoirs, fuel tanks, coolant overflow bottles, and sun visors.
