Characteristic:
The shell of the night vision device is made of magnesium alloy material, with a sturdy structure and a surface coated with anti-oxidation and anti salt spray coating. It is resistant to hurricanes and can work normally at wind speeds of 150 kilometers per hour. It has good waterproof and high/low temperature resistance characteristics and can adapt to various harsh environments and work all day long. Moreover, the magnesium alloy night vision device is lightweight and durable, making it very suitable for long-term carrying.
It is worth noting that this magnesium alloy night vision device adopts the unique semi-solid forming process of EMT, which has fast forming speed and high precision, and is suitable for large-scale production.
The principle of the semi-solid injection molding equipment for magnesium alloys:
The magnesium alloy particle raw material enters the semi-solid slurry preparation tube (material tube) by negative pressure and gravity, and is hot melted in the material tube to form a solid-liquid two-phase mixture (semi-solid slurry) under the action of screw stirring and shearing. Due to the stirring and shearing, the solid phase becomes spherical and the slurry has good fluidity. In this state, the slurry is high-speed pressed into the mold for molding, cooled and shaped, and the integrated magnesium alloy product can be obtained.
