Product Description

HRA 87.5 Non-Magnetic Alloy MV Series Mold Insert Precision Injection Mold Core For Sensitive Applications

The HRA 87.5 Non-Magnetic MV Series Mold Insert is engineered to meet critical manufacturing challenges. This performance-critical component is designed for applications where absolute non-magnetic properties, consistent hardness, and superior wear resistance are essential for maintaining flawless production cycles and part integrity.

Core Technology & Design Advantages

Optimized Material Performance (HRA 87.5): The specific hardness rating of 87.5 HRA represents a meticulously balanced formulation that provides significantly higher wear resistance than tool steel while maintaining superior toughness and crack resistance compared to harder, more brittle carbides.
Guaranteed Non-Magnetic Property: Utilizing a specialized nickel-based binder system, this insert is completely free of iron and cobalt with magnetic permeability (µ) < 1.002, ensuring zero magnetic attraction or interference for sensitive applications.
Thermal & Chemical Stability: Excellent dimensional stability across injection molding temperature ranges and high resistance to corrosion from engineering plastics and cleaning agents.

Target Industries

Industry	Problem Solved by Our MV Insert	vs. Traditional Steel Insert
Medical Device Molding	Eliminates risk of magnetic contamination in implantable or MRI-compatible part molds. Offers 3-5x longer life molding abrasive bio-polymers.	Potential for trace magnetism; requires frequent polishing/replacement.
Precision Electronics & Connectors	Exceptional wear resistance maintains critical pin alignment and contact cavity dimensions over millions of cycles. Non-magnetic ensures no interference with final component function.	Dimensional wear leads to increased scrap rates. Possible residual magnetism in sensitive components.
Optical & Consumer Electronics	Capable of ultra-high polish (Ra <0.1µm) for glossy finishes. Hardness prevents scratches and wear from glass-filled plastics.	Polish degrades faster; surface defects can appear over production runs.
