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 this critical challenge. This isn‘t just a mold core; it’s a performance-critical component designed for applications where absolute non-magnetic properties, consistent hardness, and superior wear resistance are non-negotiable for maintaining flawless production cycles and part integrity.
Optimized Material Performance (HRA 87.5): The specific hardness rating of 87.5 HRA represents a meticulously balanced formulation. It provides significantly higher wear resistance than tool steel (typically HRC 52-60) while maintaining a superior level of toughness and crack resistance compared to harder, more brittle carbides. This balance minimizes chipping risk during ejection and extends service life in demanding molding cycles.
Guaranteed Non-Magnetic Property: Utilizing a specialized nickel-based (Ni) or other non-ferromagnetic binder system, this insert is completely free of iron and cobalt. Its magnetic permeability (µ) is < 1.002, ensuring zero magnetic attraction or interference. This is critical for molding components used in MRI equipment, sensors, or any application where residual magnetism could impair function.
Thermal & Chemical Stability: Exhibits excellent dimensional stability across the typical injection molding temperature range and high resistance to corrosion from engineering plastics and cleaning agents.
| Parameter | Specification / Capability | |
|---|---|---|
| Core Material | Non-Magnetic Hard Alloy (WC-Ni based or equivalent) | |
| Hardness | 87.5 HRA (Guaranteed, with tight batch-to-batch consistency) | |
| Magnetic Permeability (µ) | < 1.002 (Certifiable per batch) | |
| Key Tolerances | Core Dimensions: ±0.005mm (Standard), ±0.002mm (Precision) | |
| Cavity Profile: As per customer drawing, achievable to ±0.003mm | ||
| Surface Finish | Standard: Ra 0.4 µm | High-Grade: Ra 0.1 µm or better (Optical Polish) |
| Standard Applications | Micro-gears, sensor housings, connector components, medical device parts, optical lens mounts |
This insert solves specific problems in advanced manufacturing sectors:
| 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. |
Certified Performance: Each batch can be supplied with material certification and hardness test reports.
Advanced Manufacturing & Finishing: We employ state-of-the-art CNC grinding, EDM, and polishing technology to achieve the precise geometries and surface finishes demanded by your design.
Full Customization & Support: We don‘t just sell standard inserts. We engineer solutions based on your part drawing, material, and production volume. Technical consultation is available to optimize design for manufacturability.
Global Supply Chain Reliability: We understand the needs of international customers, offering reliable lead times, professional export documentation, and responsive communication.
