Title:
FORMATION OF COATING FILM BY DIPPING AND COATING FILM FORMING DEVICE THEREFOR
Document Type and Number:
Japanese Patent JPH03229899
Kind Code:
A
Abstract:
PURPOSE:To secure the dipping time in each tank for a material to be treated and to form a coating film with excellent productivity in the film forming device by dipping such as electrodeposition coating and electroplating by continuously moving the material through a pretreating tank, treating tank and post-treating tank by the vertical and forward movement of an engaging part. CONSTITUTION:A work W is passed through a pretreating tank 3 consisting of a high-pressure hot water washing tank 30, a degreasing tank 31, first to fifth water washing tanks 32, 33, 36, 37 and 38, a chemical conversion tank 35 and a draining tank 39 and then through an electrodeposition tank 4 and a post-treating tank 6 consisting of water washing tanks 60, 61 and 62 and a dewatering tank 63 and electrodepositon-coated or plated to form a film. The work W is fixed to an engaging part 10, and a conveyor 1 is moved forward in the X direction by a driving mechanism 11. In this case, a dipping and transferring part 5 is provided to the tank 4, the work W is moved forward while dipped in the tank 4 having the length L greater than the advance pitch P of the engaging part 10, hence the work W is rapidly moved in an electrodeposition coating soln. 40 and dipped for an enough time, and a film is formed on the work W with excellent productivity.
