    摘要： 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.

    摘要： A method for producing ceramic composite bodies, in particular, cylindrical ceramic bodies for sheathed-element glow plugs, in which a plurality of shaping sleeves, which accommodate piece parts premolded by cold pressing, are inserted into corresponding bore holes of a vertically standing supporting plate that is heated via additional bore holes with the aid of cartridge heaters or a heat transfer liquid. The vertically standing supporting plate with the shaping sleeves is then clamped between two press plates of a press, and the piece parts located inside are subsequently pressed by press pins which, on both sides, pass through the press plates and into the shaping sleeves. Upon completion of the necessary pressure keeping period, the pressed compound, after retraction of the press pins and opening the press, can be hardened in a non-pressurized manner in the shaping sleeves located in the withdrawn supporting plate that is subjected to further heating. Finally, the pressed material can be removed from the shaping sleeves after the same have been cooled by air, and can be ground into the final shape using a grinding machine.

    摘要翻译： 一种用于制造陶瓷复合体的方法，特别是用于护套电热塞的圆柱形陶瓷体，其中容纳通过冷压预成型的片状部件的多个成形套筒插入垂直支撑板的相应的钻孔中 借助于筒式加热器或传热液体，通过附加的孔加热。 然后将具有成形套筒的垂直支撑板夹紧在两个压力机的压板之间，随后通过压力销将压在两个侧面上的零件通过压板压入成型套筒中。 在完成必要的压力保持期后，压制复合物在压针缩回和打开压力机之后可以以非加压的方式硬化在位于被进一步加热的退回的支撑板中的成型套筒中。 最后，压制后的材料可以在空气冷却后从成型套筒中取出，并可以使用研磨机研磨成最终形状。
