Technical requirements of high vertical bright annealing furnace , equipment manufacturers equipment maintenance and stainless steel 304 sheet supply requirements are very strict, which part of the equipment maintenance and spare parts supply and delivery service only , does not provide the drawings , expensive.
Improve the quality of stainless steel and die life , should use different names and stainless steel metal forming material friction material , and taking into account the size of drawing parts and production quantities .
1 large size stainless steel deep drawing stainless steel parts , not very large production volume, in order to stainless steel sheet 304 , should use cast iron HT300, QT600-2 , etc., as convex and concave mold materials, may also be of special cast iron .
2 , small and medium size stainless steel deep drawing parts , copper based alloys generally used as mold material, such as aluminum bronze, aluminum and iron bronze, phosphor bronze .
