Abstract
The invention relates to a method for producing a molded plastic part, including the steps of: spraying a quasi-endless plastic tube with an annular gap of a spray head; shaping and at least partially cooling the plastic tube with a molding line connecting to the spray head. In particular, the molding line includes a number of recirculation molding jaws, the molded plastic part is configured as a repeat unit of the plastic tube shaped by the molding jaws.
Claims23
A method for producing a molded plastic part, including:
- a. Spraying of a quasi-endless plastic tube by means of an annular gap of a spray head;
- b. Forming and at least partial cooling of the plastic rube by means of a molding line connecting to the spray head, where the molding line includes a number of recirculation molding jaws and the molded plastic part is configured as a repeat unit of the plastic tube shaped by the molding jaws;
- and
- c. Severing of at least one of the repeat units from the shaped plastic tube as a molded plastic part.
Device for producing a molded plastic part, including a spray head with at least one annular gap, and a molding line mounted downstream of the spray head, where the molding line includes a number of recirculating molding jaws, characterized in that the molded part can be configured in a shape of at least one part of at least one of the molding jaws, where by means of the recirculation of the molding jaws a quasi-endless plastic tube can be configured with plastic parts in succession that are connected as one piece.
Use of a device for producing a plastic tube to produce molded plastic parts,
- wherein the device includes a spray head with at least one annular gap and a molding line mounted downstream of the spray head with a number of recirculation molding jaws,
- wherein the molded plastic parts can be severed individually from a molded plastic tube,
- wherein at least one of the molding jaws for producing a plastic tube is exchanged with a molding jaw for producing the molded plastic part.
