What Are The Special Properties Of Graphite Molds?

Graphite mold is a basic process equipment widely used in industrial production, especially high-temperature sintering industry. The mold industry is the basic industry of the national economy. In modern industrial production, stamping, forging forming, die-casting forming, extrusion forming, plastic injection or other forming processing methods are widely used for product parts, which are matched with forming molds to form blanks into parts that meet product requirements. All types of products we use in our daily production and lifestyle, ranging from the base from the machine device, the covering of the equipment equipment, to the small size of a screw, button and the shell of various household appliances, are all closely related to molds. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products.
The following are the special properties of graphite molds:
1. Excellent thermal conductivity and electrical conductivity;
2. Low coefficient of linear expansion, good thermal stability and thermal shock resistance;
3. Chemical corrosion resistance is not easy to react with most metals;
4. At high temperature (the sintering temperature of most copper-based carcass is above 800°C), the strength increases with the increase of temperature;
5. Excellent lubrication and wear resistance;
6. It is easy to process, has good machining performance, and can be made into molds with complex shapes and high precision.
The graphite mold industry is developing rapidly. Graphite materials, new processes and increasing mold factories are constantly impacting the mold market. Graphite has gradually become the first choice for mold making due to its outstanding physical and chemical properties. In high-temperature occupations, the use of graphite molds has excellent special properties.
