摘要： A system and process is provided for cladding the interior of plasticating barrels or any other interior surface. The cladding operation uses a laser head that carries out a spiral welding operation to create a smoother lining than is capable with conventional welding techniques. A number of different techniques can be used, including the use of feeding laser energy at one end of a tube to be reflected from laser aiming optics inserted through a second end of the tube. Unidirectional welding can be used to facilitate gravity as a smoothing agent. In another embodiment omnidirectional welding can be carried out using a shaped mirror and a donut-shaped laser pattern. The cladding operation can be simplified by baking a coating of the welding matrix and anti-abrasive material onto the interior of the surface to be clad prior to the welding operation.

摘要： A screw for use in an plasticating injection apparatus includes a plurality of interrupted primary flights. An outer surface of a primary valley is formed by the primary flights and features a plurality of plateaus. The plateaus span adjacent sections of the primary flights and define shallow levels between deeper levels of the primary valleys. This depth differential contributes to a turbulent mixing action which, along with the primary and secondary valleys, contributes to improve mixing action within a metering section of the screw. The primary flights are interrupted by secondary valleys which are of opposite hand to the primary valleys.

摘要： A plasticating screw and method of plasticating without thermal degradation problems. Said screw having a metering section with a helical flight disposed within and cooperating with the innerwall of a heated barrel. In particular, solid resinous material is introduced to a helical valley extending between said flight. The resinous material is heated and plasticized by said apparatus while being advanced along a helical path towards an outlet opening by the rotation of said screw. The bottom surface of the helical valley in said metering section having a plurality of geometrically shaped surfaces in side-by-side relation with at least two of said shaped surfaces being sloped. During operation, the level differential between the shaped surfaces induces a continuous tumbling, variable shear and mixing action upon the molten resin as the molten resin in the metering section flows along the helical path.

摘要： A plasticating apparatus and method for its use including a rotating screw having a helical flight disposed within and cooperating with the inner wall of a heated barrel with said barrel provided with inlet and outlet openings so that particles of resinous material are introduced through said inlet opening to a helical valley extending along said flight to be plasticated by said screw and advanced towards said outlet opening. A barrier extends along said helical valley to divide said helical valley into coextensive side by side helical valley sections. The barrier extends in a path which is non-parallel and alternating with respect to the helical flight so that the pitch of the barrier is alternately greater than and less than the pitch of the helical flight. The height of the barrier is less than the height of the flight so that the resinous material overflows the barrier due to changes in width of said side by side helical valley sections.

The helical screw is removed from the barrel without removing the barrel from its operating site. A grooving device is transported from a remote location to the plasticating operation site and mounted within the barrel with a portion protruding from the barrel. A brace is attached to the end of the barrel to help support the grooving device. Periodic adjustments are made to the grooving device by manual or automatic manipulation of the grooving device.

摘要： A plasticating apparatus including a rotating screw having a helical flight disposed within and cooperating with the inner wall of a heated barrel. Resinous material is introduced to a helical valley extending along said flight to be plasticated by said screw and advanced towards an outlet opening. The screw has a metering section for working said resinous material at high temperature. The bottom surface of the helical valley in said metering section is divided into side by side relatively shallow and relatively deep levels having a depth differential therebetween. The relatively shallow and relatively deep levels extend along the bottom surface of the helical valley in side by side helical paths. The side by side helical paths have a different pitch than the pitch of the helical flight so that the helical flight periodically interrupts the helical paths. The depth of the shallow level remains substantially uniform in the metering section and the depth of the deep level also remains substantially uniform in the metering section. The depth differential between the shallow and deep levels is bridged by a descending-ascending shoulder without any intervening barrier flight. During operation, the level differential induces a continuous tumbling and mixing action upon the molten resin in the mixing section.
