xts on α-set
xts on pep-set
α-set — is a mold making process characterized by the hardening of polyphenolate resins by the action of an ether-based hardener. The process has been specifically designed to both improve the quality of castings and improve the working conditions of foundry workers.
Pep-set is a modern phenol-urethene system for the production of molds and cores, which is analogous to a cold box system, only curing is performed here with a liquid, not gaseous amine.
This allows this system to be used on conventional equipment for XTS processes.
