How to decide how many parts to a mould.
Hello everyone,
Hope everyone is doing well.
I want to make a mould for an angular bowl. I have attached a sample picture taken from the internet. I wanted to understand how many parts are needed when making a mould, not necessarily for this bowl but for any other ware. some are 2 parts and some go uptown 4 parts, but how to decide how many parts are needed and why they are needed.
Thanks a lot.
The main reason you use a mold, to form a ceramic piece, is to reduce the effort necessary to make the piece. One impact, of the molding process, is that the cast piece will have a seam where the molds parts come together. If the seam, is placed well, the cleaning process will be minimal. If the seam is not placed well, the cleaning process will be time consuming, and the seam may be evident after cleaning.
The form you picture may come out of a one piece mold but its hard to tell without
