Cobalt Alloy Mold Punches for the Glass Mold Industry

In the glass mold industry's production, punches are key components whose performance directly affects production efficiency and product quality. Various materials are commonly used to manufacture punches, including nickel-based alloys, mold steel, laser-clad hard alloys, and welded stellite alloys. However, with their outstanding performance, solid cobalt alloy punches have become the preferred choice in this field.

The core advantages of solid cobalt alloy punches are reflected in several key performance characteristics. They exhibit exceptional red hardness, maintaining good hardness and strength in high-temperature environments to meet the high-temperature requirements of glass production; excellent wear resistance reduces wear during long-term use, extending service life; oxidation resistance prevents corrosion in high-temperature oxidizing environments, maintaining stable performance; and its good thermal fatigue resistance enables it to withstand repeated temperature changes, reducing the risk of damage caused by thermal stress.

These properties make solid cobalt alloy punches suitable for long-line mold production lines. In long-line production, continuous equipment operation is critical, and solid cobalt alloy punches can significantly reduce equipment downtime—reducing the number of shutdowns for maintenance caused by punch damage or performance degradation, ensuring production continuity. Additionally, stable performance reduces scrap generation and associated costs. Furthermore, its consistent performance enhances product quality uniformity, ensuring that the produced glass products meet standards.

Notably, the cobalt alloy punch is suitable for producing high-borosilicate and borosilicate glass. The production of such glasses imposes higher performance requirements on mold components, and the cobalt alloy punch precisely meets these demands, providing reliable production support.

In the current glass mold industry, which prioritizes efficient and stable production, the monolithic cobalt alloy punch stands out for its exceptional performance, making it an ideal choice for enhancing production efficiency.
