    摘要： According to a known method for producing a component by means of a powdery starting material, powder is mixed with auxiliaries comprising binding agents, whereby a free-flowing mass is produced. A green body is produced from the mass by means of powder injection moulding. A portion of the auxiliaries is extracted by heating the green body in a container and exposing said body to a stream of solvents. The green body is sintered, whereby the component is produced. The aim of the invention is to enable fast and gentle extraction for releasing green bodies which are produced by means of powder injection moulding. According to the invention, the extraction comprises a heating-up phase during which the temperature of the green body is permanently or gradually increased and the green body is overflown by solvent in the form of a compressed, supercritical treatment gas. An extractor that is suitable for carrying out said method is characterised by a pressure sealed housing that is provided with at least one lateral limiting wall and encloses a treatment chamber for receiving a carrier element which is loaded with a plurality of green bodies. Said housing is provided with a lock-up load and removal opening for the green bodies. Said opening is configured in the lateral limiting wall as a passage for the carrier element.

    摘要翻译： 根据通过粉末状原料制造组分的已知方法，将粉末与包含粘合剂的助剂混合，从而产生自由流动的物料。 通过粉末注射成型从坯料制成生坯体。 通过加热容器中的生坯并将所述的身体暴露于溶剂流中来提取一部分助剂。 生坯被烧结，由此制成部件。 本发明的目的是能够快速和温和地提取用于释放通过粉末注射成型生产的生坯体。 根据本发明，提取包括一个加温阶段，在该阶段，生坯体的温度永久地或逐渐增加，并且生坯以压缩的超临界处理气体形式的溶剂溢出。 适于执行所述方法的提取器的特征在于具有至少一个侧向限制壁的压力密封的壳体，并且包围处理室，用于接收装载有多个生坯体的载体元件。 所述壳体设置有用于生坯的锁定装载和拆卸开口。 所述开口构造在横向限制壁中作为载体元件的通道。

    摘要： The invention deals with some improvements on chambers intended for setting concrete parts, as well as with the necessary complementary components to transfer the concrete parts from the production machine up to the chamber part outlet. One of the improvements consists of a certain mechanism, named transfer unit, which carries out the transportation of panels loaded with parts from the moulding machine up to a lifter responsible for raising and introducing those panels in the different floors of the chamber. Another improvement consists in providing the lifter with a counterweight stop and some moving arms to push the panels properly and prevent them from getting on top of each other, as well as to open the respective chamber gates. The chamber is a little bit inclined to facilitate the panel movement. Another improvement consists of a rolling path made up of a wheel-shaft-self-levelling bracket assembly as well as a spray watering system and an individual little roof per floor.
