High Frequency Core Knockout Hammer

Updated: 2026-08-05

Overview

The High-Frequency Core Removing Air Hammer is a specialized industrial tool designed for the efficient removal of sand cores in metal casting processes. It utilizes compressed air to generate high-frequency vibrations, which break down and dislodge sand cores without damaging the metal castings. This tool is essential in foundries and casting workshops, where precision and speed are critical. Its lightweight design and ergonomic handling make it suitable for prolonged use, reducing operator fatigue. The tool is compatible with various casting materials, including aluminum, iron, and steel, making it versatile for different industrial applications.

Structure and Working Principle

The High-Frequency Core Removing Air Hammer consists of a pneumatic motor, a vibration mechanism, and a hammer head. The pneumatic motor converts compressed air into mechanical energy, driving the vibration mechanism to produce high-frequency oscillations. These vibrations are transmitted to the hammer head, which impacts the sand core, causing it to crumble and separate from the casting. The tool operates at frequencies ranging from 50Hz to 200Hz, depending on the model. The high-frequency vibrations ensure efficient core removal while minimizing the risk of damaging the casting. The tool's compact design allows for easy maneuverability in tight spaces, making it ideal for intricate casting geometries.
