What Are Methods To Prolong The Life Of Aluminum Die Casting Mold

Extending The Life Of Aluminum Alloy Die Casting Mold

1. Material selection of aluminum die casting mold

The material selection of aluminum alloy die casting mold, die casting mold material and material heat treatment are the main factors affecting the mold life. The mold material includes cavity material and sleeve plate material.

Cavity material and heat treatment are the main direct factors affecting the service life of the mold. The damage of aluminum alloy die casting mold is mainly manifested in two forms: one is cracking and the other is surface cracking. According to different casting requirements and different die casting conditions, selecting appropriate mold steel and optimizing heat treatment process are important ways to prolong die casting mold life.

The liner material, including slideway and strip material, is also the factor affecting the service life of the mold. Die casting is a high-pressure casting process. The specific pressure of die casting is generally – kg / cm2, and the impact pressure acting on the die-casting cavity is very large. The sleeve plate is very important as the fixing of the cavity, sliding and locking of the sliding block. Improper selection will also affect the service life of the mold. Therefore, the appropriate sleeve material must be selected according to different casting requirements, different die-casting conditions and cavity materials.

2. Mold design

Die casting mold design is another important factor affecting the life of aluminum die casting mold. The quality of mold design directly affects the life of die casting mold. Therefore, when designing the die casting mold, we must fully consider the factors affecting the mold life according to the characteristics of the casting, reasonably design the mold structure, and timely put forward improvement suggestions or take reasonable measures to solve the casting design affecting the mold life in the early stage. In the mold design, we should comprehensively consider the mold strength, the speed of the gate in the mold, the strength of the locking block of the mold slider, the speed and strength of the aluminum sealing surface of the mold cavity, whether the mold cooling is reasonable, and the use of advanced technology and equipment.

3. Mold manufacturing

Mold manufacturing process and mold manufacturing accuracy are also important factors affecting mold life. Therefore, in mold manufacturing, we must pay close attention to all links affecting mold life, study and improve them, so as to improve our mold life and our mold manufacturing level.

4. Preheating of the mold

Preheating of the mold is another technique that can increase its lifespan. Usually, cracks can occur when the hot molten metal is poured into the mold, which results in a quick exchange of temperature. Preheating the mold can prevent the formation of any cracks due to such processes.

It is best to heat with a blowtorch or gas if the mold has a complex design. A slow press shot is perfect for a simple mold design, as preheating can actually prepare the mold surface for accepting the high temperatures of the molten metal.

5. Mold use and maintenance

The use and maintenance of die-casting die is also an important part affecting the service life of die casting mold. Correct use and maintenance of die casting mold is the key to improve production efficiency, product quality and economic benefits. Prolonging the service life of aluminum die casting mold is very important for improving the economic benefits of die-casting enterprises. Therefore, die casting enterprises must pay close attention to the use and maintenance of die-casting molds.

The service life of aluminum alloy die casting mold is not only to consider the die casting experience and technical level of an aluminum alloy die casting manufacturer, but also an important way to improve the economic benefits of aluminum alloy die casting manufacturers. Therefore, every link is very important. We must strictly control every link in each die casting production process to ensure the efficient production of high-quality aluminum alloy die castings.
