phenomenon prediction
The middle part of the die-casting shell is prone to collapse, and the drawing looks intact, but the concave defect is only exposed during the trial mold.
Root cause: Column convergence
The internal columns converge and form locally thick material. Uneven cooling shrinkage of thick materials results in surface shrinkage and depression.
Improvement ideas
Disperse concentrated thick materials, optimize thickness transition, and avoid shrinkage risks.
A little insight
Many problems are not related to the mold, but to insufficient structural prediction, which only consumes the cost of sampling and mold adjustment.
What can we do
Diligently cultivating and manufacturing, able to withstand repeated sample polishing. We specialize in customizing precision metal parts for small batches and multiple varieties, providing aluminum alloy die-casting, CNC, and a complete set of process support.
