Introduction of Vacuum Sintering Furnace
Oct 18,2024
In the past two or three decades, the parts produced by metal injection molding vacuum sintering furnace technology have become more and more complex, and its application fields have covered various industries. Vacuum sintering furnace is mainly used for the sintering process of semiconductor devices and power rectifiers. It can be vacuum sintering, gas protection sintering and existing sintering. It is a novel process equipment in the semiconductor special equipment series. It has novel design concept, convenient operation and compact structure. It can complete various processes on one equipment. It can also be used in other fields of vacuum heat treatment, vacuum brazing and other processes. Vacuum sintering furnace is widely used in ceramics, silicon carbide, hard alloy materials, lightness gold molding materials and graphite purification of vacuum sintering treatment, the use of vacuum sintering furnace need to repair to use a longer time. Next, the vacuum sintering circuit will be introduced.
With the increasing demand for high-quality parts with less geometric deformation and high material performance, the vacuum sintering furnace process has spread to the production lines of various industries such as automobiles, medical equipment, and mobile phone manufacturing. High power density fields such as modern automotive engines, power guns, and machine building require small mechanical systems because they can provide greater innovation potential and productivity improvements.
In order to meet the requirements of the industry for the continuous development of technical requirements and related specifications, it is necessary to explore the growth space of the accuracy and efficiency of the vacuum sintering furnace process equipment. Current limitations, such as the mechanical, chemical and optical appearance of parts, are mainly caused by the following aspects:
Uneven shrinkage (geometric deformation), uneven mixing of powder and raw materials, density fluctuations caused by injection and/or the first degreasing stage, uneven temperature in the sintering furnace.
Chemical Decomposition and Discoloration in Vacuum Sintering Furnace
Inaccurate process gas management; adhesive redeposits on the second degreasing link. Residual sinter path contaminants. In addition to these technical limitations, a competitive mayor/market environment will also pass cost pressures to component manufacturers. Therefore, in order to promote the industry by vacuum sintering, the key is higher profit, better technology production equipment and materials.
In addition to high raw material procurement costs (such as fine metal powders, polymer adhesives, and ready-made injection materials), high temperature combustion is one of the main cost drivers of the MIM process. Selecting the appropriate furnace type according to the specific production situation is a prerequisite for the success of vacuum sintering in the industry.
This is the vacuum sintering furnace that I introduce to you. If you need to know more, please feel free to contact us!
