Abstract: A wear part (5) for detachable mounting on a supporting part in an impact-type multi-action crusher is at least partly manufactured by hot isostatic pressing. The wear part (5) has a body (19) for mounting of the wear part (5) on the supporting part and a crushing layer (20) which is attached to the body (19) and which is adapted to be brought, during operation of the crusher, into repeated contact with a raw material that is to be crushed. The body (19) is made of a substance which is easy to machine to narrow tolerances, and the crushing layer (20) is made of a material (27, 28) of high abrasive resistance. In a method of manufacturing the above wear part (5), the following steps are carried out: introducing at least one powder material (27, 28) into a capsule, degassing and sealing the capsule, subjecting the material (27, 28) in the capsule to hot isostatic pressing to form a crushing layer (20), and then after treatment of the wear part (5).
