摘要:
A multi-layer bus bar unit capable of being easily made into a product coping with a demand for different specifications, reducing production costs including initial costs such as a cost for manufacturing a die, and ensuring long-term reliability is provided. Coating films 11 and 21 are deposited on a first bus bar 10 and a second bus bar 20, each formed from a metal flat plate, by an electrodeposition coating process with a polyamidimide electrodeposition coating material. The coating film 11 of the first bus bar 10 is subjected to a heating treatment to form a completely-cured resin covering layer 12, and the coating film 21 of the second bus bar 20 is subjected to a heating treatment to form a semi-cured resin covering layer 22. The first bus bar 10 and the second bus bar 20 are overlapped with each other and then subjected to a pressure and heating treatment so that the semi-cured resin covering layer 22 is completely cured. In this manner, a multi-layer bus bar unit 1 having a two-layer structure in which the first bus bar 10 and the second bus bar 20 adhere to each other by the resin covering layers 12 and 22 is formed.

The invention relates to a plant for the treatment, in particular the cataphoretic dip coating of objects, in particular of vehicle chassis (4), whereby the objects (4) are run by means of a transport car (5) through several treatment stations and on so doing are dipped in at last one treatment container (91) and retrieved therefrom again. The transport car (5) comprises a chassis (7, 8, 9 to 12), which travels along the trajectory of the objects (4), at least one pivot arm (50, 51), connected to the chassis (7, 8, 9 to 12), a mounting (61) joined to the pivot arm (50, 51), for at least one object (4) and independently operated drives (32, 33, 56, 57, 80, 81) for the translational displacement and the pivoting displacement of the at least one pivot arm (50, 51) and the mounting (61). The transport car (5) can be used not only for transport of the objects (4) for treatment but can also have a service basket (90) fixed thereto, suitable for the accommodation of at least one operative. The service basket (90) can be brought into any position which can be reached by the pivot arm (51), by means of the transport car, whereby the alignment of the service basket (90) in maintained permanently in the vertical by means of a special device (92). The operative in the service basket (90) can carry out maintenance and cleaning work on all reachable objects and surfaces in a convenient manner.
摘要:
A process for the production of coated substrates comprising the successive steps of:
a) applying a coating composition A' onto one side A" of a metal sheet to form a coating layer A which is electrically insulating when cured and applying a coating composition B' onto the opposite side of the metal sheet to form coating layer B which is electrically conductive when cured, wherein each of the coating compositions A' and B' are applied by coil coating, b) curing the two coating layers A and B, c) removing and shaping sheet metal parts provided with the cured coating layer A on one side A" and with the cured coating layer B on the other side B", d) optionally, assembling the coated shaped sheet metal parts to form a construction with outwardly directed sides A" and e) electrodepositing an ED coating layer onto the electrically conductive surfaces and curing of the ED coating layer.
