Product Introduction: High-Performance Mulite Sandwich Sintering Plate for Mn-Zn Ferrite Core Firing
Engineered for Excellence in Critical Sintering Processes
In the precise and demanding field of Mn-Zn ferrite core manufacturing, achieving consistent magnetic properties and high production yield hinges on every component of the sintering process. Our Mulite Sandwich Sintering Plate is a purpose-engineered solution designed to meet the exacting requirements of firing these essential soft magnetic materials. It serves as the critical platform that supports ferrite cores through the high-temperature sintering cycle, directly influencing final product quality, dimensional stability, and production efficiency.
Superior Design and Material Science
Constructed from high-purity mullite, a refractory ceramic renowned for its exceptional thermal stability and chemical inertness, our sintering plates offer unmatched performance. The advanced "sandwich" structure is key to its success. This design incorporates a dense, non-porous surface layer that prevents chemical interaction and contamination of the sensitive Mn-Zn ferrite cores. Beneath this surface, a tailored porous layer provides superior thermal insulation and stress relief, ensuring exceptional temperature uniformity across the entire plate surface during the prolonged and complex heating cycle, which can exceed 170 hours.
