Many clients complaint the parting-line is good when start the bulk , but many times pass, the line is worse and worse.
The one of important factors is the mold material. You need ask your factory choice the best steels for your mold. Kean Always choice P20 steel for our teething jewelry mold. Because P20 steel is very harder than other steel. Harder material is good for parting-line. If the mold material is bad , the line very be bad.
If the line is bad now , Maybe you need ask your engineer to repair it , l am sure it is work and the line will be improved.
