    摘要: Single or multiple colorants are infused into a thermoplastic material during melt processing to form preforms and plastic containers exhibiting a marbleized or swirl-type pattern. A base resin and colorant may be fed into an extruder having an extrusion screw and/or barrel modified in a manner to cause incomplete and non-uniform mixing. The modifications may include notches in some of the flights along the extrusion screw, a reduction in the depth or omission of some of the flights, a reduction in diameter of the extrusion screw, or the provision of a marbleizing torpedo near the discharge nozzle. Other techniques include introducing the colorant into vents present along the barrel, using a barrier screw to keep the components separate along the length of the barrel, using a high pressure pump for introducing the colorant near the discharge nozzle, or using multi-material co-injection techniques for co-injecting the base resin and colorant.

    摘要: A kneading segment kneads materials such that insufficiently kneaded portions would not remain as gel. The kneading segment is rotatably disposed on a kneading screw housed in a barrel having an inner cavity, and is provided with a kneading flight which kneads the material in the barrel by rotating according to the kneading screw's rotation. The top surface of the kneading flight is formed with a concaved cutout section. The cutout section is surrounded by two side surfaces, which face the axial direction, and a bottom surface, which is disposed between the side surfaces. The bottom surface of the cutout section is formed in a tilted planar shape in relation to the top surface. The opening of the cutout section, which faces one side of the rotational direction of the kneading screw, has a larger area than the opening which faces the other side.
