Abstract
A simple method for passivation of a component is presented which is particularly suitable for processing high-viscosity plastics. The component is arranged in a preproduced plastic body and is connected to the body. This method is proposed for the production of a piezoactuator arrangement, which is utilized for controlling injection valves in internal-combustion engines. The plastic consists of solid silicone and/or fluorinated silicone elastomer.
Claims16
A method for producing an electrical or electronic component which comprises an outer surface that is passivated with a plastic coating, the method comprising the steps of:
- providing a body of plastic material comprising at least partially cross-linked plastic for accommodating and encapsulating a portion of the outer surface of the component, said body being a hollow body having an inside surface that is inverse in form to the outer surface of the component and an outer surface;
- inserting the component into the body;
- then
- joining the surface of the component to the body by applying pressure to the outer surface of the body of plastic material;
- and cross-link the plastic during or after the applying of the pressure;
- wherein;
- applying pressure utilizes a quasi-isostatic application of pressure that causes the plastic to free-flow and serve as a medium of uniform pressure transmission.
A method for producing an electrical or electronic component having an outer surface passivated by a plastic coating, the method comprising the steps of:
- providing a component with the outer surface;
- molding a plastic material comprising at least partially cross-linked plastic to form a tubular body having an outside surface and a hollow space with an inside surface that is inverse in form to the outer surface of the component;
- inserting the component into the hollow space of the tubular the body;
- then
- applying pressure to an outer surface of the body to join the inside surface of the hollow space to the outer surface of the component to secure the plastic coating on the outer surface of the component;
- and cross-link the plastic during or after the applying of the pressure;
- wherein
- applying pressure utilizes a guasi-isostatic application of pressure that causes the plastic to free-flow and serve as a medium of uniform pressure transmission.
A method for producing an electrical or electronic component which comprises an outer surface that is passivated with a plastic coating, said outer surface having at least one contact lug connected to an electrical terminal, the method comprising the steps of:
- providing a body of plastic material comprising at least partially cross-linked plastic for accommodating and encapsulating a portion of the outer surface of the component, said body being a hollow body having an inside surface that is inverse in form to the outer surface of the component, the contact lug and terminal;
- inserting the component into the body;
- joining the surface of the component to the body by applying pressure to an outer surface of the body of plastic material to pressure the inside surface of the body on the contact lug, a portion of the terminal and the outer surface of the component;
- wherein
- applying pressure utilizes a guasi-isostatic application of pressure that causes the plastic to free-flow and serve as a medium of uniform pressure transmission:
- the method further comprising:
- cross-linking the plastic during or after the applying of the pressure.
