Product introduction

     Manufactured from high-quality Permalloy sheets and fabricated through precise laser cutting, CNC stamping, and precision bending processes, our components offer a well-balanced combination of mechanical strength and dimensional stability. Designed for critical high-tech fields that require complex forming structures, lightweight integration, and accurate positioning, they deliver stable magnetic shielding performance while meeting customized structural integration needs.

Core Features:

1. High-Precision Sheet Metal Forming
Utilizing high-precision CNC punch presses or laser cutting equipment, along with precision bending dies, we strictly control dimensional tolerances for complex shapes, irregular cutouts, mounting tabs, and flanged edges. The high mating accuracy and excellent assembly consistency among multiple parts significantly improve our clients' assembly efficiency and product yield.

2. Excellent Mechanical Performance & Structural Rigidity
Through optimized sheet metal bending designs, the overall rigidity of the components is significantly enhanced without adding extra thickness. Furthermore, precision processing preserves the uniform physical properties inherent to the Permalloy sheet, ensuring structural stability and resistance to deformation under demanding operating conditions.

3. Stable High-Permeability Magnetic Shielding
Manufactured from high-nickel (approx. 80%) Permalloy material, combined with strict post-processing (such as stress relief or protective atmosphere annealing) after stamping and bending, our components effectively eliminate internal stresses caused by cold working. This maintains the material's high initial permeability (μi) and maximum permeability (μmax), allowing it to efficiently absorb and shield external stray electromagnetic fields, creating a magnetically "quiet" space for internal precision circuits.

Primary Applications:

• Precision Instruments: Used as internal shielding liners or structural      support frames for current transformers, magnetoresistive sensors, and other precision instruments, providing both magnetic isolation and secure positioning.

  
  

• Medical & High-End Electronics: Used as internal precision shielding enclosures for MRI equipment and high-precision medical detection instruments, protecting sensitive circuits from weak external magnetic interference.
  

  
  

• Aerospace & Defense: Serves as lightweight shielding structural parts for electronic instrument cabins in spacecraft and radar equipment, ensuring reliable localized magnetic protection while reducing weight.
  

  
  

• Communication & RF Front-Ends: Applied as internal shielding partitions within high-sensitivity RF receivers and filters to prevent crosstalk between cavities and ensure signal purity.
  

  
  

• Semiconductor Manufacturing Equipment: Used as internal magnetic shielding support brackets within vacuum chambers or precision transfer components.
