Cold Box Core Shooter Machine – Precision Core Making for Modern Foundries

on


 In foundry production, the quality of the core directly impacts the quality of the casting. Achieving accurate, strong, and defect-free cores is essential for consistent results. The Cold Box Core Shooter Machine from OM Foundry Equipments is designed to deliver exactly that — high-quality cores with precision, speed, and reliability.

What is a Cold Box Core Shooter Machine?

A Cold Box Core Shooter Machine is used to produce sand cores using a chemical process where a gas catalyst (usually amine gas) cures the resin-coated sand inside a core box at room temperature (“cold”). Unlike hot box methods, this process eliminates the need for external heating, resulting in faster cycle times, lower energy consumption, and excellent dimensional accuracy.

How the Cold Box Process Works

  1. Core Sand Preparation – The sand is mixed with a suitable resin binder.

  2. Core Shooting – The prepared sand is blown into the core box using compressed air.

  3. Gas Curing – A catalyst gas (like triethylamine) is passed through the core box to harden the core instantly.

  4. Core Ejection – Once cured, the core is ejected, ready for immediate use in the mould.

This process ensures fast, uniform curing and high core strength, making it ideal for complex and high-volume casting applications.
