Injection molding of cemented carbide belongs to the powder injection molding process (PIM), which is complex and has many influencing factors. Improving and stabilizing the properties of cemented carbide during the PIM process is always the most difficult point in PIM process.

Solvent debinding is widely used in the debinding process of cemented carbide injection molding. Parameters of solvent debinding process have an important impact on the degreasing process and product quality, in which the influence of degreasing temperature is particularly obvious. The temperature not only affects the debinding rate, but also has obvious influence on the bubble, cracking and other defects.

Injection molding technology has been widely used in the field of cemented carbide production as a result of its excellent characteristics. In the field of cemented carbide production, the two-step degreasing process is most commonly used solvent degreasing + thermal debinding. 

Direct methanol fuel cell is a proton exchange membrane fuel cell, which directly uses methanol water solution or steam methanol as fuel to supply power source.
