Abstract
An extruder die assembly for coating wires is disclosed. The extruder die assembly includes a head, a wire guide, and a die. The head includes an injection gate. The die has a guide receiving area. The wire guide has wire grooves arranged in a side-by-side relationship and parallel to each other while being spaced relative to each other. The wire guide inserts in the die. The die inserts in the axial opening of the head. The head receives wires through the axial opening. The injection gate receives molten plastic that gets distributed around the wires which are moved axially within the axial opening. The coated wires exit through the die while being arranged in a side-by-side contiguous relationship to provide contact areas between adjacent coated wires.
Claims20
An extruder die assembly for coating wires, said extruder die assembly comprising:
- a head comprising an axial opening and an injection gate;
- a wire guide positioned within said axial opening of said head, wherein said wire guide comprises holes configured to receive wires;
- and
- a die positioned within said axial opening and configured to receive said wire guide,
- wherein said wires draw through and move axially, through said axial opening,
- wherein said injection gate injects a coating material into said axial opening to uniformly coat said wires as said wires pass through said wire holes, and
- wherein said coated wires exit through said wire guide.
An extruder die assembly for coating wires, said extruder die assembly comprising:
- a head comprising an axial opening and an injection gate;
- a wire guide positioned within said axial opening of said head, wherein said wire guide comprises holes configured to receive wires;
- and
- a die positioned within said axial opening, wherein said die comprises a wire guide receiving area configured to receive said wire guide,
- wherein said wire guide receiving area has a larger area than the surface area of said wire guide creating a gap therebetween said wire guide and said wire guide receiving area,
- wherein said wires draw through and move axially in said axial opening,
- wherein said injection gate injects a coating material into said axial opening to uniformly coat said wires as said wires pass through said holes, and
- wherein said coated wires exit through said wire guide.
A method of coating wires, said method comprising the steps of:
- providing a head comprising an axial opening and an injection gate;
- providing a wire guide positioned within said axial opening, said wire guide comprising holes for receiving wires;
- providing a die positioned within said axial opening, said die configured for receiving said wire guide;
- drawing said wires through and moving axially in said axial opening;
- injecting a coating material into said axial opening via said injection gate for uniformly coating said wires as said said wires pass through said holes;
- and
- exiting said coated wires through said wire guide.
