PRODUCT DESCRIPTION
Introduction
Mold Bricks are specialized refractory components designed for glass forming and molding applications, including thermal bending glass, fused glass, and art glass production. They are manufactured from selected refractory raw materials through shaping, precision machining, and high-temperature treatment processes to achieve accurate dimensions, stable structure, and reliable service performance.
With a dense microstructure, low permanent linear change, good thermal shock resistance, and excellent machinability, Mold Bricks can maintain dimensional stability during repeated heating and cooling cycles, meeting the requirements of precision glass forming processes.
The products can be customized according to customer drawings, dimensions, curvature requirements, and specific application conditions. Customized processing helps reduce machining workload, improve installation efficiency, and ensure better compatibility with glass forming equipment.
Sunrise provides customized Mold Bricks with different shapes, sizes, surface finishes, and processing options according to customer requirements.
