摘要 |
The invention relates to a pre-treatment device and method for production of a thixotropic metal bolt (10), in a casting chamber (30) of a thixo-moulding unit. The pre-treatment device comprises a container (14), for accommodating a metal bolt (10), an oven (20), for converting the metal bolt (10) in the container (14) into a partly fluid thixotropic state and a transport unit for transporting and feeding the thixotropic metal bolt (10), into the casting chamber (30). The container (14) is a cylinder-shape heating tube (14), with closable sides. Furthermore, the pre-treatment device is so arranged that, during the entire pre-treatment, namely the heating process in the oven (20), the transport into the casting chamber (30) and the period in the casting chamber (30), the metal bolt (10) remains in the heating tube (14).
