A single-piece component for a magnetic actuator, in particular for fuel injection, including an internal pole, a magnetic sleeve, and a non-magnetic separating sleeve, the internal pole, the magnetic sleeve and the separating sleeve being integrated into the single-piece component. A method for manufacturing a single-piece component for an magnetic actuator with the aid of a two-component powder injection molding method.

Component for a magnetic actuator as well as a method for its manufacture

In a method for preparing an ester from an hydroxybenzoic acid and a fatty alcohol for use in a binder system for powder injection molding, transesterification of an ester of the hydroxybenzoic acid and a low alcohol using the fatty alcohol is carried out, the fatty alcohol and the ester of the hydroxybenzoic acid and the low alcohol forming a reaction mixture and being used in an essentially equimolar ratio. The transesterification is carried out at a temperature at which the ester of the hydroxybenzoic acid and the low alcohol and the fatty alcohol are present as a homogeneous melt. The binder system for a powder injection molding contains 80 to 98 wt. % of a metal powder and/or a ceramic powder and 1 to 19 wt. % of a polymeric binder component, and 1 to 19 wt. % of at least one ester prepared by the transesterification.

Method for preparing an ester and binder system

A fuel injection valve for injecting fuel includes: a coil, an internal pole, a valve sleeve, and a magnetic separating element, where the valve sleeve and the magnetic separating element are embodied in one piece as a powder injection-molded component, and the valve sleeve forms a magnetic region and the magnetic separating element forms a non-magnetic region, which are intermaterially joined to one another.

Fuel injector valve

An armature for an injector including at least one magnetic region and at least one non-magnetic region, the armature being developed as a one-piece component, the magnetic and non-magnetic regions being integrally connected to each other by a two-component powder injection molding process, and the magnetic region being completely enclosed by the non-magnetic region.

Armature for a fuel injector

An injector having a valve opening, a cylindrical pipe, a valve opening, a valve needle situated inside the pipe in the radial direction and guided to allow axial displacement; a solenoid coil situated outside the pipe in the radial direction; a solenoid core disposed inside the pipe in the radial direction; and a magnetic armature situated inside the pipe, opposite the solenoid core in the radial direction, the magnetic armature being disposed on the valve needle. The pipe is a magnetic first material in a first pipe region and a third pipe region, the first region facing the valve opening in the axial direction, and the third pipe region facing away from the valve opening in the axial direction. The pipe is a non-magnetic second material in a second pipe region, the second pipe region being between the first pipe region and the third pipe region in the axial direction.

Pole body for solenoid valves produced by multi-component MIM

A solenoid armature for a solenoid actuator, including at least one magnetic region and at least one non-magnetic region, the solenoid armature being configured as a one-piece component having a first and second armature end face, the magnetic and non-magnetic regions being integrally bonded to each other by a two-component powder injection molding technique, and the magnetic region and the non-magnetic region extending in the axial direction at least as far as the first armature end face.

Solenoid armature

A sensor element having a layered construction and configured to detect a physical property of a gas or a liquid includes a functional component situated in the interior, which functional component is connected electrically to a conductor element, which conductor element extends up to the outer surface or up into the surroundings of the sensor element. The sensor element has at least one sealing element which adjoins the functional component and/or the conductor element. The conductor element and the at least one sealing element are configured to be gas-tight at least regionally in the interior of the sensor element and are situated in such a way that the functional component is separated gas-tight from the surroundings of the sensor element.

Sensor element containing a sealing element for a functional component

A spark plug electrode, which is produced from an electrode material containing nickel as base material, 0.5 to 3 atom % of silicon, and at least 6 atom % of aluminum.
