Its structure is more complex, is a punch, * male, aged 44,mulberry, professor, master tutor Received Date :2006-08-22; Revision Date :2006 -11-22 local shape,hollister wijnegem, multiple bending, forming box and other processes of the small size parts. Meanwhile,ralph lauren sverige, to ensure that the plug part and supporting a reliable contact, plug into the power requirements of less than 6.5N,abercrombie hamburg, after 5 plug pull-out strength after not less than 4N. This gives a higher forming part requirements. In addition, thin material parts, small size, on demand,hollister roma, so the die design and stamping made a special request.
