Secondary operations - treatments performed after the initial metal stamping process. Cleaning, heat treating, plating or deburring.
Stop block - a block used to act as a reference point for the height of the tool set up.

Is there any real difference in metal stamping and roll forming?
ReplyDeleteI'm not sure I know the difference between the two. I've read articles on Roll Forming (Samco Machinery seems to be a leader http://www.samco-machinery.com) on Industrial Machinery News (http://www.industrial-machinery-news.com) that talk a lot about rollformers.
I'd like to hear your comments on the difference of these two technologies.
Hai Tong Metal Products limited provides many kinds of dies for example single station dies, several station dies, compound dies, progressive dies and conjunction press lines.
