The best casting technology scale for excavator bucket tooth inner cavity must be zone or minus

Only the technology scale for liebherr excavator lock pins tooth top part has change into minus one percent to three percent according to drawing dimension, and the technology scale for excavator bucket tooth seat part choose one to three percent on the basic of drawing dimension, even under the influence of manufacturing core, coating paint and heat treatment influence, professional liebherr excavator lock pins production supplier said both of the excavator bucket tooth top and tooth seat can be assemble with non gap anymore, which is match with the standard using performance, so professional liebherr excavator lock pins production supplier said the suitable trial technology scale for excavator bucket tooth inner cavity must be zero or minus.

The main reason is due to the steel water needs flowing into the excavator tooth inner cavity sand molding part, so the sand molding would be fully covered by steel water, but because of the too high temperature and worse heat dissipation prospect, the sand core would produce the linear expansion to eliminate the shrinkage for alloy liquid, but lead to the rough casting has no linear shrinkage or micro expansion phenomenon, so the best casting technology scale for liebherr excavator lock pins tooth inner cavity must choose zero or minus value.
