Product details
Metal materials are highly deformed and soft at high temperatures, while graphite has high hardness, good electrical conductivity, radiation resistance, corrosion resistance, good thermal conductivity, low cost, and high temperature resistance. Graphite has opposite properties to changes in metal temperature rise. The higher the temperature, the harder the body is, so there is no problem of deformation. Therefore, the glass hot bending mold is made of graphite material, which can ensure the maximum degree of precision, and the difficulty of mold processing is also reduced.
Glass hot bending mold graphite characteristics
1. High purity and high density of graphite
The high purity prevents the graphite from being oxidized at high temperature to produce bubbles, which makes the surface smoother; the high density prevents the collapse of the graphite mold, improves the mechanical strength, and ensures the life of the mold is greatly improved!
2. Small particle diameter
The 3D glass hot bending mold body is a graphite concave type rectangular body, and the cavity is a preset curved surface; wherein the cavity and the push plate are obtained by fine polishing. The graphite material of the graphite material used in Longdao has a small diameter, the surface of the graphite mold cavity is smoother, and the surface effect of the 3D glass is also better.
Graphite mold processing features
In the first step, select the high quality graphite material according to the above requirements.
In the second step, the entire piece of graphite material is cut into the required size in the cutting room.
In the third step, the graphite material enters the CNC machining center for forming engraving, and the carbon CNC computer needs high processing speed and high precision.
In the fourth step, after the mold is formed, the final graphite polishing can be performed on the polishing machine, and the polishing is completed. After the dimensional inspection of the three-dimensional detector, the production can be put into production. Polishing of the cavity of the graphite mold is a major difficulty. Hongsheng's equipment selection and polishing material selection can overcome this series of problems.
As an important consumable of 3D glass hot bending, graphite mold directly affects the surface finish and curvature of 3D glass. The service life of graphite mold also has a great impact on the cost of 3D glass hot bending.
