AI Technical Summary
In the current processing of polytetrafluoroethylene rods, insufficient heating of the particles before pressing leads to high friction, making it difficult for them to flow and fuse smoothly, thus affecting the uniformity of filling the mold cavity.
A pushing device was designed. By manually moving the support column, the slider is driven to bring the heating plate close to the mold, thereby preheating the particles. The sieve plate shaking mechanism disperses the adhering particles, ensuring that the particles enter the mold independently.
It effectively reduces particle viscosity, making them easier to slide and blend, ensuring uniform distribution within the mold, and improving the density uniformity of the bar stock.
