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. |
