Drafting Standards for Aluminum Extruded Products

standard by The Aluminum Association , 2012

This publication was written to help create a uniform method of preparing extrusion profile drawings, since extrusion profile drawings are constantly being exchanged between customers and extruders. Certain basic methods of dimensioning are important to enable the extruder to maintain reasonable efficiency in the manufacture of extrusion tools and in the inspection of extruded material. Adoption of these dimensioning methods by the customer will help insure that the extruder will obtain a suitable and economically produced product.
