Casting Dimensional Error

Problem Description:Incorrect estimation of thermal expansion and contraction ratios or misalignment of the shell mold will lead to dimensional deviation.

Solution:

• Accurately calculate shrinkage and adjust mold size according to product structure.
• Use locating mechanisms (such as pin holes or locating surfaces) to ensure that the upper and lower shell molds are aligned.
• Regularly calibrate molds and heating equipment to avoid cumulative dimensional errors.
