In Die Casting process, The Decorative pattern problem should be considered.
1, filling too fast.
2, too much paint.
3, the mold temperature is low.
1, reduce the injection speed as much as possible.
2, coating dosage is thin and even.
3, improve the mold temperature.
The part has requirement of surface finish of E-Coating, which has process of curing in hot thermal oven, the temperature usually be up to 170-200 degree, the porosity mentioned above will expand and get out from the part, result in pits and bubbles on the coating. So for the first article inspection, the operator of die casting work shop and the QC inspector will fracture the part to confirm the status of the section view, to judge if the density is enough or not. The inspector also will make a record of the part weight, then, during routine inspection, they will just need to weigh the part to see if the part weight is offset the standard weight too much, if so, fracture again to look into the section. By such prevention action, the parts can be avoided batches scrap during outsourced e-coating.
