Abstract: A molding system is provided, which includes at least one mold part and a heating and cooling module. The at least one mold part defines a mold cavity having an opening. The heating and cooling module is inserted into the opening to close the mold cavity. The heating and cooling module includes a die insert defining a mold surface, a layered heater for heating the mold surface, and a cooling unit for cooling the mold surface. The layered heater is disposed between the die insert and the cooling unit and includes functional layers formed directly on a surface of the cooling unit or a surface of the die insert opposite to the mold surface by using layered or layering processes selected from a group consisting of thick film, thin film, thermal spray and sol-gel processes.

Abstract: An electrical heating device for medical equipment is provided. The heating device includes a body, which may be an insulating body forming a channel therethrough for fluid travel, an insulating material surrounding the body, and a heater surrounding the body and the insulating material. In other forms, the electrical heating device for medical equipment has a conducting body, instead of an insulating body, forming a channel therethrough for fluid travel. A base dielectric layer is disposed on the conducting body, and a heater surrounds the base dielectric layer and the conducting body. A top dielectric layer is disposed on the heater, and a protection housing surrounds the top dielectric layer.

Abstract: An instrumented heater sleeve is provided that has a plurality of zones, a dielectric layer disposed over an outer surface of the sleeve, a resistive element layer disposed over the first dielectric layer, and a plurality of pairs of lead wires secured to a portion of the resistive element layer. Each pair of lead wires is connected to and corresponds with each of the zones and a protective layer is disposed over the dielectric layer. An amount of power is supplied to each of the zones and adjusted during a test run, or multiple test runs, to achieve a desired temperature profile along a heating target such as a hot runner nozzle. Methods of designing a hot runner nozzle heater using the instrumented heater sleeve are also provided.

Abstract: A hot runner nozzle heater is provided that includes a sleeve defining a slot extending along a length of the sleeve. A first dielectric layer is disposed over an outer surface of the sleeve, and a resistive element layer is disposed over the first dielectric layer, wherein the resistive element layer defines a resistive circuit pattern that is preferably formed by a laser trimming process. A pair of terminal leads are secured to a portion of the resistive element layer thus defining a termination area, and the termination area is positioned proximate the slot and away from the proximal end and the distal end of the sleeve. A second dielectric layer is disposed over the resistive element layer but not over the termination area, a third dielectric layer is disposed over the termination area, and a protective layer disposed over the second dielectric layer and the third dielectric layer.
