Low-density metal and low-density metal manufacturing method

Abstract

The invention discloses a low-density metal manufacturing method. The low-density metal manufacturing method comprises the following steps that a metal powder material and a high polymer material are provided, and the metal powder material and the high polymer material are mixed together to form particles; and the particles are fed into an injection machine to form a required green body, degreasing is carried out, and curing is carried out at high temperature to form a product. The degreasing and curing process is used for removing high polymer materials in the green body and connecting the high polymer materials with metal powder particles, and apertures are formed in the product and communicate with one another to form gaps. The metal material and the high polymer material are mixed and then jointly injected to form the green body, then the high polymer material is removed through the degreasing process, intercommunicating gaps are formed after the high polymer material is removed, and the gaps are uniform and continuous, so that compared with the prior art, stable production of products with low density and complicated configuration can be realized, and the application of the metal material is greatly exerted.

Description

technical field [0001] The invention relates to a metal manufacturing method, in particular to a low-density metal and a manufacturing method thereof. Background technique [0002] In electronic communication or medical equipment, materials with better thermal conductivity are often used to realize the heating of liquid into gaseous state to meet other purposes. For example, a certain device needs to use a material with gaps and heat conduction, so that the liquid medium can enter the gap and quickly atomize from liquid to gas, so as to achieve other functional purposes required in the future; on the contrary, the condensation effect is the same. [0003] At present, there are metal materials on the market, which are made into products with voids by pressing or slurry casting. Because of the poor distribution of voids and non-uniform density of the key properties of the press-molded products, and the slurry cast molding parts, they do not have continuous voids or have no vo...

AI Technical Summary

Problems solved by technology

Due to the poor distribution of voids that characterize the key performance of the pressed molding product, the density is not uniform, and the slurry casting molded parts do not have continuous voids or there are no voids, so they cannot achieve penetration

Due to the limitations of the characteristics of the pressing and pouring process, it is also impossible to make products with various high-complexity configurations, that is, the above-mentioned existing technologies cannot meet the market demand.

[0004] In addition, ceramic materials are also used. The processing technology is pressing, and there are also defects in the pressing process. The voids after molding are unevenly distributed, resulting in poor capillary function, and some even have closed and non-circulating phenomena.

At the same time, ceramic materials have poor thermal conductivity, long gasification delay, and low efficiency
