Method of fusion welding of thermoplastic components

摘要: A method for bonding together surfaces of two three-dimensional articles foamed thermoplastic material along mutual abutting surfaces. The includes securing a pair discrete in fixture means first mounting position with the being disposed substantially mutually relationship to form juncture zone. Thereafter, heated element such as wire or knife is passed through zone at predetermined rate and into contact both surfaces, parting line separation plate preferably leading zone, thereby fusing portions edges articles. programmed motion thereafter applied least one move opposed moving second setting position. certain plane edge lagging generally parallel element, maintained entire area until fused become solidified.
