Title: Method and device for molding thermoplastic resin
Inventor: KAWAHARA MASA
IPC: B29C48/86
Filed: 1986-05-20
Abstract: PURPOSE:To restrict neck-in phenomenon and improve the quality as well as the production efficiency of a product by a method wherein the surface temperature of the end of a thermoplastic resin film, which contacts with a deckle for regulating the extruding width of the film, is controlled. CONSTITUTION:The rims of a resin film 2, extruded from an extruding die 1, are held by a deckle 3, fixed to the extruding die 1 through a deckle holder 4 and bolts 6 and provided with a built-in heater, and the resin film 2 is pressed and cooled between a cooling roll 7 and a nip roll 8, then, is molded through a separating roll 9 and is discharged. The surface temperature of the deckle 3 with the built-in heater 5 depends upon the temperature of delivered resin and the thickness of a thermoplastic resin film to be molded, however, in case the temperature of the resin is 300 deg. and the thickness of the thermoplastic resin film to be molded is 20mum, for example, the surface temperature of the deckle 3 is kept within the temperature of 300-400 deg., for example. When an air cooling hole is provided at the tip end of the dickel and the temperature of the tip end of the resin film only is reduced slightly, a flow resistance with respect to neck-in may be increased and, as a result, the amount of neck-in may be reduced.
