Die-casting molds sometimes fail in the process of die-casting production. The causes of failure are mainly caused by the following three aspects. The following is a brief introduction:

For prolonging the service life of precision die-casting molds, it is also more important to perform cooling work in time when the temperature is high.

Aluminum die casting is to melt aluminum into a liquid, inject it into the cavity of a die casting mold under high pressure and high speed, and after the aluminum is cooled by water, open the mold to obtain a molded product.

1. Cold partition Features: The gaps that appear when the metal flows with lower temperature butt but are not fused are irregular linear, there are two kinds of penetrating and non-penetrating, and there is a development trend under the action of external force.

1. Cold partition Exclusions: 1. Properly increase the pouring temperature and mold temperature. 2. Change the alloy composition and improve the fluidity.

In 1838, in order to make molds for movable type printing, people invented die-casting equipment.
