CORESHOOTER PF 12

The “PF 12” shooting machine is an advanced device designed for the production of cores using the Cold-Box process. This machine can handle both vertically and horizontally divided core boxes, operating fully automatically with a pre-set single cycle that can be customized.

Key Features:

• Intelligent hydraulic clamping group: Equipped with grooved plates, the closing system is managed by hydraulic cylinders with automatic position recognition.
• Types of core boxes:
  • Divided into two parts vertically
  • Divided into three parts (two halves plus a bottom)
  • Divided into two parts horizontally
  • Single-piece open-top core boxes
• Movement: All movements of the core box parts are carried out via hydraulic controls.
