摘要:
The invention relates to a method for producing an ester from a hydroxybenzoic acid and a fatty alcohol for use in a binder system for powder injection moulding by transesterification of an ester from the hydroxybenzoic acid and a lower alcohol having the fatty alcohol, wherein the fatty alcohol and the ester from the hydroxybenzoic acid and the lower alcohol form a reaction mixture and are used substantially equimolar, wherein the transesterification is carried out at a temperature at which the ester from the hydroxybenzoic acid and the lower alcohol and the fatty alcohol are present as a homogenous melt. The invention furthermore relates to a binder system for a powder injection moulding method, comprising 80 to 98 wt % of a metal powder and/or ceramic powder and 1 to 19 wt % of a polymer binder component, wherein there is furthermore 1 to 19 wt % of at least ester, produced from hydroxybenzoic acid and fatty alcohol according to the method according to the invention.
摘要:
The invention relates to a method for producing a connection of at least one rotary component (30) to a shaft (10), wherein the at least one rotary component has a central opening (20) and the shaft has a first section (50) along the shaft and a second section (60) on an end face (65) of the shaft, wherein the method comprises the following steps: fixing the shaft at the first section thereof in the central opening of the at least one rotary component by means of an eccentric arrangement (71), such that the shaft is fixed in the radial direction relative to the at least one rotary component; and fixing the shaft at the second section thereof by press-fitting a ball (40), so that the shaft is secured in the axial direction relative to the at least one rotary component; wherein each fixing step is carried out by means of positive engagement.

The invention relates to a method for producing an assembly (100), wherein the method has a provision step and a heating step. In the provision step, a first component (102) made of a first material is provided, wherein a second material (104) is disposed in a receptacle of the first component (102) . In the heating step, the first component (102) and the second material (104) are heated at least to a reaction temperature of the second material (104) and/or of the first material in order to connect the second material (104) and the first component (102).
摘要:
The invention relates to a solenoid armature for an injection valve comprising at least one magnetic region (3) and at least one non-magnetic region (4), wherein the solenoid armature (2) is designed as a one-piece component, wherein the magnetic and non-magnetic regions (3, 4) are firmly bonded to each other by a two-component powder injection molding method and the magnetic region (3) is completely enclosed by the non-magnetic region (4).
