Metal Forming Process
Cold Forging: Utilizing the Cold Forging Relay Core process, soft magnet blanks are forged into the basic core shape at room temperature using a die. Compared to casting, this increases material density by 30%, avoiding defects such as internal porosity and looseness.
Precision Turning: The cold-forged workpiece undergoes CNC turning to precisely control key dimensions such as Custom Core Pins diameter, step height, and end-face flatness, ensuring assembly compatibility.
Surface Treatment: A passivation process forms a uniform protective film on the Electromagnet Iron Core surface, achieving a rust-proof rating of no corrosion after 48 hours of salt spray testing, extending product lifespan.
Full Inspection and Packaging: Each batch of Cold Forging Relay Cores undergoes dimensional inspection, magnetic performance testing, and a full visual inspection to ensure a 100% factory pass rate. Packaging uses anti-static pallets and sealed bags to prevent damage during transportation.
