We know these problems, as we have been facing them ourselves for 5 years
Augers are actively used in many fields of activity. Intensive usage requires their periodic replacement. You can regularly buy them, increasing the burden on the budget, or produce them yourself, facing several problems:

It is not possible to achieve the correct screw geometry and exact dimensions
The process of making one segment takes too long
You have to constantly change the forming tool, which increases the time of work
It is difficult or impossible to change the height of the flange
Difficulties arise during the bending of great-thickness metal.
The purchase of modern equipment will solve this problem, paying off in just 2.5 months for the manufacture of 3 augers per month.
