    摘要: A thick-film electric heater having thick-film layers applied directly on a thermally conductive non-flat substrate. Preferably, the substrate is cylindrically shaped. A dielectric layer is silk-screened on the substrate surface. A resistive layer is silk-screened on the dielectric layer to form a circuit for the generation of heat. The resistive layer has at least one resistive trace in a pattern that is discontinuous circumferentially. At least a pair of silk-screened contact pads are applied in electrical communication with the resistive layer for electrical connection to a power source. An insulation layer is applied over the resistive layer.

    摘要: A manifold system (50) comprising a main manifold (56) with a plurality of arms (64), a plurality of sub-manifolds (52) spaced from the main manifold (56) and communicating with the main manifold (56) through a plurality of melt transfer bushings (68) disposed between the main manifold (56) and the sub-manifolds (52). The melt transfer bushings (68) may include static mixers (140) to homogenize the melt. An air plate (70) is disposed between a backing plate (58) preferably housing the main manifold (56) and a manifold plate (54) preferably housing the sub-manifolds (52). The air plate (70) has a plurality of air channels (74) that communicate with valve gate nozzle actuators (90), which are received in actuator cavities (72) in the air plate (70). The air plate (70) is bolted to the manifold plate (54), and the backing plate (58) is bolted to the air plate (70) with bolting patterns not constrained by location of the main manifold (56) or sub-manifolds (52). The manifold system (50), as shown in FIG. 5, has better thermal and geometric balance, closer nozzle spacing, and better bolting for less plate bowing.

    摘要: An apparatus for injecting plastic material comprises a manifold having a melt channel and a flat sealing surface, and a nozzle assembly seated directly against the flat sealing surface. The nozzle assembly includes a nozzle body having an axial channel aligned, in use, with the melt channel in the manifold for communicating a flow of material therein. The nozzle body has a non-flat sealing surface adjacent the flat sealing surface, thereby forming a sealing interface to seal the nozzle body with the manifold. The flat sealing surface may be on an end of a bushing mounted into the manifold. The non-flat surface may have a conical profile, preferably defined by an angle less than one degree, and preferably between 0.2 to 0.4 degrees, from a plane parallel to the flat sealing surface. The non-flat surface may have a spherical profile, preferably having a radius between 350 mm and 4000 mm.
