What’s choice of lightweight materials in the field of hot stamping？

Etched Magnesium Edition - The choice of lightweight materials in the field of hot stamping!

In the field of etching materials, especially as bronzing or embossing consumables, the lightweight of materials is an important feature that determines high-quality metal molds, and is also an important means to improve efficiency and reduce labor costs. Traditional copper, zinc, steel and other materials often have problems such as heavy metal environmental pollution, high transportation cost, slow etching efficiency, inconvenient installation and sticking, and overloading of pressing equipment due to their high density. Substitute material.

Magnesium alloys, as a typical representative of lightweight metals, have been used as bronzing/pressing consumables in the field of etching in European and American countries for more than 50 years, and are now recognized and used by more and more enterprises.

Let me show you a set of data:

The density of magnesium is 1.73g/cm3, the density of copper is 8.96g/cm3, the density of zinc is 7.14g/cm3, and the density of steel is 7.85g/cm3. It can be seen that the density of magnesium is only 1/5 of that of copper and 1/4 of that of zinc and steel. Therefore, magnesium alloys are small in quality and light in weight, and have great advantages in transportation, installation, and storage.

For example, for a 2.00mm×610mm×914mm etching plate, if it is a magnesium plate, its weight is only 1.93kg, but if it is a zinc plate, the weight is as high as 7.96kg, and the copper plate is heavier, up to 9.99kg, so the magnesium plate Compared with zinc plate and copper plate, there are obvious differences in density, which will greatly reduce the cost of transportation, installation and storage.

In addition, metals with a density greater than 4.5g/cm3 in the traditional sense are called heavy metals, such as copper, zinc, and steel, which belong to the category of heavy metals. Due to their potential harm to the environment and human body, corresponding environmental protection policies limit the discharge of these heavy metal ions . Magnesium is a typical light metal, so it is more environmentally friendly to apply magnesium alloys in the field of etching.
