The minimum tolerance requirements depend on the size of the product.
For dimensions up to 200mm, tolerances of ±0.1mm or better are required.
For dimensions up to 300mm, tolerances of ±0.2mm or better are necessary;
and for dimensions up to 500mm, tolerances of ±0.3mm or better are expected.
As for draft angles, a minimum of 1 degree is required, but larger angles are preferred for smoother ejection from the mold.
These tolerance specifications are essential to ensure the precision and quality of die-cast products.
