Established in 1988, Earth-Chain Enterprise Co., Ltd. is a leading Taiwanese manufacturer of magnetic workholding solutions. With over three decades of experience, more than 30 patents, ISO 9001 and CE certifications, and multiple prestigious awards—such as the Taiwan Excellence Award and the Taiwan SMEs Innovation Award—Earth-Chain has earned a global reputation for excellence in the design and manufacturing of Electro-Energetic Permanent Magnets, more commonly known as Electro-Permanent Magnetics (EEPM), including Electro-Permanent Magnetic Chucks, Permanent Magnetic Clamping Blocks, Electro-Permanent Lifting Magnets, and more. As a pioneer in magnetic clamping systems, Earth-Chain's private label "E.C.E." is distributed across five continents through a network of agents and distributors in more than 40 countries. The company’s dedication to innovation, honesty, and responsibility makes it the ideal partner for high-performance magnetic solutions.
An Electro-Permanent Magnetic Chuck combines the advantages of both permanent and electro-magnetic systems. It uses an electrical pulse (lasting just 1–3 seconds) to magnetize or demagnetize the chuck, but once magnetized, no continuous electrical supply is required to maintain the magnetic force. This not only enhances energy efficiency but also increases operator safety by ensuring the magnetic hold is maintained even in the event of a power failure.
Key Features of EEPM Chucks:
• Instant ON/OFF operation in 1–3 seconds
• No power needed during operation
• Stable and high clamping force
• Heat-free operation, preserving workpiece accuracy
• Compatible with CNC and automated systems
• Highly customizable for various applications

The Importance of High-Quality Magnetic Workholding and Lifting Equipment
In industrial applications, magnetic workholding systems like EEPM Chucks and lifting magnets eliminate the need for mechanical clamps, reducing deformation, setup time, and vibration during machining. They also enhance the accuracy of cuts and allow full access to all sides of the workpiece.
When choosing magnetic systems, key factors to consider include:
• Magnetic Force Stability: To prevent slippage and ensure consistent performance.
• Heat Management: Systems should operate without generating heat that affects accuracy.
• Energy Efficiency: Systems like EEPM that don’t require continuous power save energy and increase safety.
• Customization Capability: Tailored solutions optimize clamping and lifting for specific workpieces.
