摘要： The present invention relates to an electrical heater (22) for heating substantially cylindrical objects (12), particularly for heating hot runner nozzles (10) for hot runner systems, having at least one substantially cylindrical carrier and at least one heat conductor strip (28) attached to the carrier (12). In order to reduce the causes of a premature outage of the heater, the invention provides for each heat conductor strip (28) to extend substantially in the axial direction (A) of the carrier (12), wherein the heat conductor strips (28) are electrically connected to one another by conductive strips (30) with a low electrical resistance, and where each conductive strip (30) extends substantially in the tangential direction (T) of the carrier (12).

摘要： An apparatus for retaining a heater on an injection molding nozzle comprises a retaining body configured to fit around the injection molding nozzle. The retaining body has two flanges extending inward. One is configured to be received in a groove in the injection molding nozzle; the other is configured to be received in a groove in the heater. An axial slot allows the retaining body to elastically spread outward. The retaining body also has at least one aperture that receives a thermocouple. The aperture is preferably an elongated hole having an axis parallel to a longitudinal axis of the retaining body. Preferably the heater is a thick-film heater and the thermocouple is installed adjacent one on the resistive elements of the thick-film heater. When the resistive elements produce different heat levels, the thermocouple is preferably installed adjacent the resistive element that produces the greatest heat.

摘要： A heater assembly is provided that includes a substrate having opposed end portions defining raised flanges, a slot extending between the opposed end portions, and opposed chamfered surfaces extending along the slot and across the raised flanges. In one form, a plurality of layers are disposed onto the substrate, along with a pair of terminal pads. A protective cover defining at least one aperture is disposed over the layers and is secured to the raised flanges and the opposed chamfered surfaces of the substrate, and the aperture is disposed proximate the terminal pads. A pair of lead wires is secured to the pair of terminal pads, and a lead cap assembly is disposed around the pair of lead wires and is secured to the protective cover. Methods of manufacturing the heater assembly are also provided in accordance with the present disclosure.

摘要： Coinjection molding nozzle apparatus and method includes structure and/or steps whereby a first nozzle melt channel is kept thermally separated from a second nozzle melt channel. Preferably, grooves in the nozzle body or a separate nozzle pipe keep the first and second nozzle melt channels thermally separated. Preferably, a highly thermally conductive nozzle tip is removably coupled to the nozzle body and includes first and second nozzle tip melt channels that merge together before the mold gate.

摘要： Erfindungsgegenstand ist ein Heizelement für metallene Kunststoffspritzdüsen mit einem rohrartigen Hohlkörper (2) aus Metall, der den Düsenkörper einer Spritzgießeinrichtung wärmeübertragend umschließt. In seiner äußeren und/oder inneren Mantelfläche besitzt der Hohlkörper eine oder mehrere zumindest abschnittweise gewindeartig verlaufende Nuten (3, 4) mit eingelegtem(n) Rohrheizkörper(n) (5), deren elektrische Anschlüsse (6, 7) vom Hohlkörper (2) wegragen. Außerdem ist in einer Führungsnut (4) ein Thermoelement angeordnet, dessen Fühlerspitze (9) in einem Endbereich der Rohrwand mit der Materialwand (15) der Kunststoffspritzdüse (17) in thermischem Kontakt steht. Damit die zu regelnde Temperatur des Materialrohres am immer gleichen Messpunkt weitgehend homogen und dem direkten Einfluss der Heizung weitgehend entzogen ist, ist die Fühlerspitze (9) in einer nutartigen Ausnehmung (11) eines Rohrwandabschnitts (20) wärmeübertragend fixiert, der durch zwei stirnseitige Einschnitte (21,22) seitlich von der Rohrwand (2') thermisch getrennt ist und der radial biegsam unter einer radialen Anpresskraft stehend mit flächenhaftem thermischem Kontakt spaltfrei am Düsenkörper (15) anliegt.

摘要： Disclosed herein is an injection apparatus (1) and control method thereof. The apparatus comprises a nozzle (21) to guide a raw material to flow into an injection mold (70), a microwave transmission part positioned at a portion of the nozzle (21), and a microwave generation part (50) positioned near the nozzle (21) to generate and irradiate microwaves to the microwave transmission part. With this structure, vulcanization of the raw material injected into the injection mold (70) occurs uniformly and rapidly within the injection mold (70), thereby improving a quality of an injection molded product while increasing a speed of injection operation.

摘要： A cylindrical switch (40) has one or more passages (42, 43) which open onto a lateral cylindrical surface (41) of the switch. The switch is capable of being tightly received in a cylindrical hole (18) in a hot plate (10) and of being selectively orientated so that the passages (42, 43) are angularly in line with or offset from two or more channels (15-17) in the hot plate which open onto the hole (18) in order to selectively permit, interrupt or divert the flow of molten plastics material between the aforesaid channels. The switch incorporates a circuit (50) for a cooling fluid.
