Next, after the hardening treatment, the masking is removed, and finish processing is performed to a predetermined thickness by mechanical finishing such as turning to complete. Each step will be described in detail below. The preheating process is important for obtaining a predetermined coating, and the range of the preheating temperature is within the range of the temperature of the resin and varies depending on the work.

It is. The preheating time is the time required for sufficient preheating up to the core of the work. Preheating temperature is high. 量 Coating amount increases. However, if the preheating temperature is too high, it is not preferable because voids (nests) are generated during the subsequent curing. The immersion time in the fluidized bed is the time until the powder coating is applied to the desired thickness on the other side of the work, and varies depending on the work. ~ Kinsin.

When the preform is heated and melted, air may be entrained and voids may be formed in the coating layer. In this case, this pod is not a fool loved as a surface irregularity when turning the surface of the coating layer, which is a later layer, but exists in the coating layer part.
