The principle and application of the new technology of die-casting mold surface treatment!

Die-casting molds are a large category of molds. With the rapid development of my country's automobile and motorcycle industry, the die-casting industry has ushered in a new period of development. At the same time, higher requirements are put forward for the comprehensive mechanical properties and life of die-casting molds. To meet the ever-increasing performance requirements, it is still difficult to meet the application of new mold materials alone. Various surface treatment technologies must be applied to the surface treatment of die-casting molds to achieve the requirements for high efficiency, high precision and long life of die-casting molds. . Among various molds, the working conditions of die-casting molds are relatively harsh.

Share how the graphite material is made into ductile iron?

Nodular cast iron is cast iron in which graphite exists in a spherical form. Graphite also has special properties due to its structure: high temperature resistance, electrical conductivity, thermal conductivity, smoothness, chemical stability, plasticity, thermal shock resistance, etc. Formally because of these characteristics, graphite is widely used in the foundry industry and is deeply liked by foundry companies.

How does the ductile iron rod pressure reducing valve work?

The compressed air with pressure P1 is input from the left end and throttled by valve port 10, and the pressure drops to P2 output. The size of P2 can be adjusted by adjusting springs 2 and 3. Rotate the knob 1 clockwise, compress the springs 2, 3 and the diaphragm 5 to move the valve core 8 down, and increase the opening of the valve port 10 to increase P2. If the knob 1 is turned counterclockwise, the opening of the valve port 10 decreases, and P2 decreases accordingly.
