Non-magnetic Mould Tool Steel
Fushun are main manufacturer of tool steel for Non-magnetic Mould.
What is Non-magnetic Mould?
A non-magnetic mold is a specialized tooling designed to have zero or extremely low magnetic permeability, making it ideal for manufacturing components used in sensitive electronic, medical, and precision instruments. These molds are constructed from specific non-magnetic materials and alloys that maintain their non-magnetic properties throughout the entire temperature range of the molding process. Unlike conventional molds, non-magnetic molds ensure that the finished products will not interfere with magnetic fields or sensitive electronic equipment.
The primary function of non-magnetic molds is to produce parts that require absolute magnetic neutrality, such as components for medical imaging equipment, electronic housings, aerospace parts, and scientific instruments. These molds must maintain their non-magnetic properties even under high pressure and temperature conditions typical in the molding process. The design considerations include special attention to all components, including ejector pins, cooling channels, and other mechanical elements, which must also be manufactured from non-magnetic materials to maintain the mold’s overall non-magnetic integrity.
The materials used in non-magnetic molds possess unique characteristics that combine non-magnetic properties with the necessary mechanical and thermal properties required for molding operations. These materials typically include special grades of austenitic stainless steels and other non-ferrous alloys that exhibit high wear resistance, good thermal conductivity, and excellent corrosion resistance while maintaining zero magnetic response. The mold materials must also demonstrate good machinability and polishability to achieve the required surface finishes and dimensional accuracy. Special heat treatments and surface modifications may be applied to enhance wear resistance and surface properties without introducing any magnetic characteristics.
