Production Introduction:
This is common high strength steel product, spring back concerns for the side walls. As the product shape, the two sides are easily open to each angle. The key problem is to deal with spring back.
In the initial forming simulation, the report not showed serious bad results. And the process not complicated, we have confidence in making the product in good quality in a reasonable lead time.
Based on our experience, for right and left cavity parts, sometime, the two parts in different status not identical. Then further die tuning works are slightly changed.
After carefully process discussion and analysis, machining goes smoothly, everything goes in order, the first die off part nearly at T2 level, better than T1 quality targets. Both the sample and die have been measured and scanned, every point that in NG condition have been checked, even forming steels, inserts surface. Heat-treatment and surface coating.
