The Impact of Laser Hardening on Mold Life

Discover how laser hardening can extend mold life by improving surface hardness and wear resistance.

Overview

One contemporary method of heat treatment is laser hardening. It swiftly heats and cools the mold surface using a laser beam. This increases the molds’ wear resistance and surface hardness, which can greatly increase their lifespan. Let’s investigate the impact of laser hardening on mold life.

Laser Hardening Improves Surface Hardness

Mold surfaces are significantly tougher after laser hardening. The mold surface is heated by the laser to a high degree and swiftly cooled. This results in a hard martensitic coating changing the surface structure. High wear resistance and hardness characterize this layer. It prolongs the mold’s life by assisting in its resistance to wear and friction.

Reducing Cracks and Deformation

Laser hardening is a fast process with minimal distortion. This keeps the surface of the mold in good condition by reducing distortion and cracks during the process. With laser hardening, temperature and depth may be precisely controlled, in contrast to traditional procedures. This increases the stability and evenness of the hard coating on the mold, extending its useful life.

Better Wear Resistance

Fast-moving elements frequently cause friction and impact on molds. This may erode and harm the surface. Mold surface hardness is significantly increased by laser hardening. This lessens the wear and tear by assisting them in withstanding impact and friction. Thus, the mold has a longer shelf life.

Enhancing Performance During Heat Fatigue

Molds with laser hardening also perform better against heat fatigue. The frequent heating and cooling cycles that molds experience can lead to fatigue damage and heat cracks. The mold’s surface becomes stronger and tougher after laser hardening. This lessens damage and lengthens the mold’s life by improving its ability to tolerate heat and weariness.

In summary

In conclusion, by raising surface hardness, decreasing cracks and deformation, strengthening wear resistance, and enhancing heat fatigue performance, laser hardening technology extends the life of molds. Laser hardening is anticipated to become more and more significant in production as a result of the continuous advancement and use of laser technology, revitalizing the mold sector.
