Abstract
A method of scrap reduction in a wheel blow-molding device includes the steps of upwardly extruding a parison and gripping a top end of the parison in a portion of a first mold coupled to the wheel blow-molding device. Then, the parison is enclosed in a second mold coupled to the wheel blow-molding device that follows the first mold. Next, the parison is cut such that a gap in the parison is created.
Claims14
A method of scrap reduction in a wheel blow-molding device, comprising:
- upwardly extruding a parison;
- gripping a top end of said parison in a portion of a first mold coupled to the wheel blow-molding device;
- enclosing said parison in a second mold coupled to the wheel blow-molding device and following said first mold;
- and
- cutting said parison, such that a gap in said parison is created.

A mold for scrap reduction in a wheel blow-molding device, the mold comprising:
- a first half and a second half, each half having a rotation direction and a transverse direction perpendicular to the rotation direction, each half having:
- a cavity, adapted to receive a first parison;
- a parison gap region adjacent to said cavity in the rotation direction;
- and
- a parison gripping region adjacent to said parison gap region, adapted to grip an end of a second parison;
- wherein when said first and second mold halves are coupled, said parison gap regions of said first and second mold halves are in contact with one another and are adapted to prevent said first parison from being blown into said parison gap region.
