Process Variations
Many, innovative, in-press techniques impart component characteristics thought virtually impossible with deep drawn stamping. They include:
A Threading - Threads are formed onto the part using a thread forming roll and arbor
B Beading - A double layer is formed to add strength or create a flange-type feature
C Side Notch - A notch is cut in the edge on the open end of the part
D Reverse Draw - Tooling inverts the material to create an internal diameter
E Side Pierce - Single or multiple holes are pierced through the sidewall of the part
F Various Shapes - Round, square or shaped stampings achieved with various dies
G Marking / Stamping - Part identification can be coined into the finished part
H Necking - A portion of the part is reduced in diameter to less than the major diameter
I Bulging - Material is displaced or stretched to create a larger diameter
