核心压缩模具由何种材料制成，其使用寿命是多少？

The core compression mold is arguably the hardest-working component in any dry ice press machine. We construct our molds from a specialized, high-strength tool steel that has been heat-treated for exceptional hardness and resistance to the extreme cold and high pressures of dry ice formation. This robust material choice is designed to prevent wear, cracking, or deformation over its long service life. With proper maintenance and operation within specified parameters, the core mold in our industrial dry ice machine is engineered to last for many years of continuous, high-volume production.
