A coating apparatus includes: a coating gun to which a voltage is applied; a coating hose for leading a coating material to the coating gun; a piston provided so as to be capable of water-tightly sliding in the coating hose; and driving means for moving the piston in the coating hose. The coating material is injected into a front part of the piston and the piston is moved toward the coating gun at the time of coating.

Coating apparatus

There is provided an electrodeposition coating apparatus for dipping a body into an electrodeposition coating liquid filled in an electrodeposition tank, which includes a first circulation system for causing a flow direction of the coating liquid in a surface area and an intermediate area through which the body passes in the electrodeposition tank to be opposite to a moving direction of the body, and a second circulation system for causing a flow direction of the coating liquid in a bottom area in the electrodeposition tank to be equal to the moving direction of the body.

Dip type surface treatment apparatus and dip type surface treatment method

The invention relates to a system for treating a surface of an article with a liquid material by dipping. This system includes (a) a major tank having therein the liquid material for dipping the article thereinto; and (b) a circulatory mechanism for circulating the liquid material through the major tank. The circulatory mechanism is arranged to make a flow of the liquid material through the major tank such that the majority of the flow is in one direction that is substantially along the longitudinal direction of the major tank. Thus, contaminants and/or bubbles are not distributed over the entire major tank, but are effectively promptly removed from the major tank. The flow of the liquid material may include a first flow of the liquid material in the major tank and a second flow that is lower than the first flow in position. The first and second flows run substantially in parallel with each other, before the first and second flows reach a downstream end thereof in the major tank. The major tank may be formed at the downstream end with a wall having a special configuration such that the first and second flows separate or diverge from each other at the downstream end, and thus the flow of the liquid material through the major tank becomes very smooth.
