Inside the Company
Engine casting oil channel, water channel core production, the use of treasure sand, gas generation is less, less tendency to produce pores, to avoid casting leakage, while conducive to the oil channel sand.
Application in the production of engine castings
Analysis of the engine cylinder block, cylinder head casting water jacket cavity cleanliness by the water jacket structure, sand core quality, paint and dip coating quality, pouring temperature and other factors, for local sintering, vein, paint sticking ash and other quality problems, the use of jewelry sand, anti-vein agent, easy stripping paint and special spray gun spray steel shot or sand blasting and other measures to improve the cavity cleanliness, to ensure the quality requirements of machining and assembly.
The application of jewel sand and anti-veining agent can solve the defects of sand core deformation, sintering and veining, and improve the quality of sand core. Dip coatings should be selected that are easy to peel. For the cleaning of the inner cavity of the water jacket of the complex cylinder block and cylinder head castings, the spray gun spraying steel shot and sand blasting process can be used to solve the cleaning of the parts that cannot be reached by the local fine shot particles due to the complex shape.
