What Is the Service Life of an S136 Mold After Heat Treatment?
S136 is a high-hardness, wear-resistant stainless steel mold steel. After proper heat treatment, its hardness typically reaches 58–62 HRC, significantly enhancing the mold’s wear and impact resistance.
Factors Affecting Mold Lifespan:
1. Mold Design and Machining Accuracy:
Optimized structural design, efficient cooling systems, and high-precision machining balance stress and temperature distribution, reducing localized wear and fatigue damage.
2. Injection Molding Process Conditions:
Parameters such as temperature, pressure, cycle frequency, product geometry, and filling behavior influence mold wear.
3. Usage and Maintenance:
Regular maintenance, timely replacement of worn components, and process optimization can effectively extend the mold’s service life.
4. Lifespan Estimates:
Under ideal conditions integrating these factors, an S136 mold with proper heat treatment generally achieves 200,000 to 500,000 injection cycles. Well-designed and well-maintained molds may even exceed these numbers.
