Three necessary structural parameters for finished excavator bucket tooth

The first necessary structural parameter is named the construction structure for casting pieces: but professional bucket tooth pin manufacturer confess that due to the different design structure for excavator bucket tooth top part and excavator bucket tooth holder, after the steel liquid direct flowing or pour into the cast molding cavity, their final shrinkage ratio would be difference as well.

The second necessary structural parameter is named the expansion of silica sand, for example, after the steel water flowing into the sand molding, professional bucket tooth pin manufacturer said the molding sand would produce linear expansion due to bearing heat energy, which would also produce phase changes at the same time, but produce the influence to the finished bucket tooth pin casting pieces assemble dimension.

The last necessary structural parameter is the surface coating paint, for example, professional bucket tooth pin manufacturer said the surface paint coating layer must be evenness, especially strict control the certain coating layer thickness on sand molding and core part within suitable range.
