High-Performance Cold Box Core Shooting Machine: Precision Engineering for Modern Foundries

Our Cold Box Core Shooting Machines are designed to meet the rigorous demands of high-volume foundry operations. By integrating advanced pneumatic systems with precise PLC control, we provide a solution that ensures dimensional accuracy, high surface finish, and rapid production cycles for complex sand cores.

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.

Why Choose Our Cold Box Core Shooters?

1. Unmatched Core Quality

Our machines utilize a unique variable-pressure blowing technology that ensures uniform sand density, even in intricate cavities. This results in cores with superior gas permeability and high mechanical strength, reducing casting defects like veins or blowholes.

2. Superior Production Efficiency

Time is money in a foundry. Our equipment features a rapid-clamping mechanism and optimized gas curing paths that significantly shorten the “dry-to-dry” cycle time. The result? More cores per hour with less energy consumption.

3. Precision Gas Dosing System

The precision-engineered gas generator ensures the exact volume of catalyst is used for each cycle. This not only guarantees a complete cure but also minimizes chemical waste and reduces environmental emissions, keeping your workshop cleaner and more compliant.
