AI Technical Summary
In existing powder molding processes, the air pressure inside the pusher box causes uneven powder entry into the mold cavity, resulting in inconsistent product density and powder leakage, which increases costs.
An exhaust valve is installed on the top front surface of the pusher box body to expel air from the storage space. Combined with the feed pipe design, this ensures uniform powder distribution and reduces air accumulation. A wear-resistant base plate is used to avoid friction damage.
This effectively avoids powder runoff caused by air accumulation, improves product quality and processing efficiency, and reduces costs.
