    Not sure if you are speaking of production or general home hobbyist there.

    A centrifuge tends to be overkill for general white metal casting for the home hobbyist and for mass production not cost effective for the small operator if that operator is trying to produce multiple copies of the same piece in a timely manner.   

    Rather than a centrifuge, a diecasting methodology would be used in commercial application or other forced/pressure system with metal molds.
    This allows high detail with efficiency of mass production.

    However, Centrifuges are very handy for one-off  and lost wax casting and we see it used especially in the art world of jewelry making.
    We also see them used in things like small run figurine casting (popular with the dungeons & dragons lot) - the cost of larger centrifugal casting machines capable of multiple part castings are in the thousands of dollars and not something the home hobbyist would most likely have a budget for.
     

    But, the question always comes down to cost of machine vs. production run requirements.


    So, "typical" is quite relative.

    For the home hobbyist - RTV with free pour or simply using artist quality plaster of Paris as the molding compound is the more "typical" casting set up for white metals - especially pewter.
     
    Please see the expose in the postings by Neptune in this thread.  This is the typical way that hobbyists have poured white metal castings over the past 100 years. It also is the far less expensive way to get into casting with very good results possible.

    You also will find the system is still used even in commercial production today.

    White metal castings do not need a centrifugal casting machine nor does brass or iron. Metal has been cast for century's before that machine came along. Sand Molds or many other types of material can be used as long as the material holds it shape and withstands the heat of the pore. You can even get a casting, if you are tough enough, by using your hand as a mold and pore into it, Like many molds that, hand mold would be for  one time use only and the quality of that casting would  probably not duplicate faithfully  the shape of the mold at the beginning of the pore. .
