In the wave of intelligent casting industry transformation, high-efficiency core making has become a core technological pillar for casting enterprises to break through capacity bottlenecks and solidify yield rates. Addressing common industry pain points in the production of thick cold box sand cores, such as long core-making cycles and insufficient demolding strength, traditional cold box resins, due to their slow curing response, low bond strength matching, and shortcomings in environmental performance, are no longer suitable for the demands of large-scale high-efficiency production, becoming a key bottleneck restricting the upgrading of casting production lines to be faster and more automated.

Based on the cutting-edge R&D concepts of high-performance molecular materials science and green intelligent casting materials, Xinda has specifically developed and launched a high-efficiency cold box resin for core making. This product solves the core contradictions of uneven curing and easy demolding damage of thick sand cores at the molecular level, achieving a breakthrough balance between instantaneous strength, demolding performance, and core-making cycle, providing core material technology support for the digital and intelligent upgrading of the core-making process for thick sand cores in the casting industry.
