Precision Pressure Casting Agriculture Machinery Front Housing, the part is a housing for DC motor on Agriculture machinery. In manufacturing process, this part probably have "white-spot" .A common concern for Die Casting mould release agents is the negative effects that may have on the coating or bonding processes. As the main role of mold release agent is to prevent adhesion between the casting and the mold surface, the use of mold release agent may affect the adhesion or coating , and if the mold release agent is not completely removed during the cleaning process, it may cause "white spot" defect. Before using spray or electroplating process, alkaline lotion is used to wash the release agent easily.
The part has request on surface finish of E-Coating to satisfy the daily application, so the density of the part is important item to control, in engineering's work instruction, the operator should fracture the part and look into the section of the fracture to see if the particles is good and dense prior to production, ensure there is no big single porosity or a lot of continuous small porosity, or while e-coating, during process of curing in over under 170-200 degree temperature, the porosity existing internal will expand to get out, leading to big cosmetic issues on this part, such as bubble, pits etc.
