Common Defects in Die Castings
Misalignment/Misalignment (Other names: Misaligned joints)Characteristics:One part of the casting is misaligned with another part on the parting surface, resulting in relative displacement (for threads, this is called misalignment).Causes:Displacement of mold inserts.Wear of mold guide components.Manufacturing errors in the inserts of the two mold halves.Remedies:Adjust and tighten the inserts.Replace the guide pillars and bushings.Repair and eliminate the error.Deformation (Other names: Twisting, Warping)Characteristics:Overall deformation of the casting whose geometry does not conform to design requirements.Causes:Poor casting structural design, causing uneven shrinkage.Premature mold opening, resulting in insufficient casting rigidity.Insufficient casting draft angle.Improper handling o...
