Making your own custom metal blanks is fast becoming a popular trend among industrial companies and even businesses small enough to run a blacksmith in their garage. The most common reasons are to save money on parts by making your own, or making it easier/more convenient to produce large quantities of one type of part. The most popular example for this is the custom metal blanking for laser engraving (not so much steel blanks)
You can make a lot of different things with your own custom metal blanks, like
Custom stampings and machined part
Custom casting
Cutouts and template
Or even just plain old punchouts
custom metal forging part exporters
