How to clean the casting mold

a. (casting mold)Clean with chemical cleaning agent.

b. (casting mold)Dry ball jet method is used to clean the core disc.

c. (casting mold)Use liquid or solid sand blasting machine for sand blasting cleaning.

(casting mold）The liquid sand blasting machine shall be used, the compressed air pressure shall be 0.5 ~ 0.7MPa, and the spraying distance shall be about 10 ~ 120mm. The cleaning medium is 90um glass pellet or 0.125mm white corundum sand to clean and maintain the core box or remove the scaling. Generally, the regular cleaning and maintenance time of the core box is 1-2. For the core box with resin scaling on the surface, the cleaning time depends on the size, scaling thickness and shape complexity of the core box. Generally, the scaling of the core box can be removed within 5-20min, The injection time has little effect on the dimensional accuracy and surface roughness of the core box. The process of using liquid sand blasting machine and glass shot to clean the core box can basically clean the thick resin scale on the surface of the core box, but it is difficult to clean the thick grooves that have not been cleaned for a long time.
