Cold Box Core Shooting Machine

Cold Box Sand Core Making Machine Overview

Cold box core shooting machine is specialized equipment used in foundries for producing cores for metal casting using the cold box process. The cores are made from a mixture of sand and a binder, which is hardened at room temperature using a chemical reaction initiated by a gas catalyst, typically amine gas.

Cold Box Core Shooter Working Principle

Shooting Sand:
The sand-binder mixture is shot into the core box under high pressure, filling the mold cavity uniformly.
Core Curing:
A gas catalyst (e.g., amine gas) is injected into the core box. The gas reacts with the binder, hardening the sand mixture within seconds.
Ejection:
Once cured, the core is ejected from the mold and is ready for use in the casting process.
