Stainless Steel Propellers are cast in one integral
piece in a ceramic mold. This process is used
by all motor manufacturers as well as a few
leading propeller manufacturers. The extra expense
is well worth the outlay compared to the cheaper
"weld-on blade" process.
In
the weld-on blade process, blades are manually
placed against the round cylinder barrel and
welded in place. Errors in blade placement and
welding "heat draws" can result in
inconsistent pitch, rake and dynamic balance.
Additionally, a welded joint is more prone to
breaking under peak loads. |
