Cold Box Core Shooter Machine, also called cold box core shooting machine, refers to adopting a core box at normal temperature and using amine(TEA, DMA, etc.) as a catalyst to cure the phenolic resin-coated sand. Both the vertical parting and horizontal parting can be used. This processing represents the mainstream of today’s sand core-making technology. It has been widely used in foundry workshops for automobiles, spare parts, engines, valves, and electrical accessories in these industries.
What Is A Cold Box Core Shooter Machine?
Cold box core shooter machine is a fully or semi-automatic machine that shoots (injects) a sand mixture (usually silica sand + resin + catalyst) into a core box (mold cavity) at high pressure to form sand cores, which are later hardened by gas curing (like amine gas or CO₂).
How Does It Work?
- Sand Mixture Preparation: Sand + Resin + Catalyst mixed.
- Sand Injection (Shooting): The sand mixture is shot into the core box using compressed air.
- Gas Curing Process: A chemical gas (like amine or CO₂) passes through the sand core, making it harden instantly.
- Core Ejection: After curing, the hardened core is removed from the core box.
- Finishing: Core trimming and inspection.
Advantages of Cold Box Core Shooter
- High-speed core production
- Very precise core shapes
- Suitable for complex & thin-walled cores
- Low energy consumption (since it doesn’t require heating)
- Consistent quality
- Instant hardening (Fast Cycle Time: 20-60 seconds)
