There are many die-casting parts around us. During the use, we must pay attention to its cleaning, so that it will not cause damage to it during use. According to the editor's understanding, the correct operation method can delay the service life of die-casting parts, so we must bear in mind its precautions during use, so that it will not affect our work. So, what is the relationship between die-casting release agent and mold temperature? Today, let the editor of our die-casting machine barrel manufacturer explain it to you!

In the production process of die-casting, die-casting release agent has always been the main method of mold cooling. When spraying water-based release agent, compressed air entrains the die-cast release agent to coat the surface of the mold while being heated by the high temperature mold surface, so that the moisture in the release agent is present without touching the surface of the mold Vaporization, and with the difference of the touch time with the surface of the mold, the temperature at which the water-based release agent is heated is also different, and the degree to which the mold is cooled by the water-based release agent is also different.

The temperature of the mold surface changes when the mold release agent is sprayed during the production process of die casting. In an aluminum alloy die-casting cycle, the temperature of the mold surface before injection can reach a minimum of about 205°C due to forced cooling. Generally, there are special circumstances. Due to the time lag of heat conduction and the role of the mold temperature control system, the mold before filling The surface temperature has a rebound of nearly 50-100°C, that is, it reaches about 250-300°C. From the requirements of aluminum alloy die-casting forming coagulation technology, it is usually best that the mold temperature should be about 40% of the aluminum alloy filling temperature. Therefore, when designing the chemical composition of the mold release agent, we usually choose the best suitable mold temperature scale. Between 250-300oC. For example, the latest release agent DL2720-SUPER from Italy Marble, as long as the user can keep the mold temperature stable at 250-300oC, the release effect is good, the appearance of the casting is very bright, the mold does not accumulate carbon, and it will not stick to the mold. Improved service life.
