Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing devices, specifically a pneumatic fully bonded variable polishing device for melt extrusion products. Background Technology
[0002] Melt extrusion is a processing technology that involves heating solid raw materials (such as plastics, rubber, metals, waxes, etc.) to above their melting point, causing them to molten; then, using devices such as screws and plungers to apply pressure, the molten material is extruded through a die of a specific shape to form a continuous profile or product with a certain shape and size.
[0003] The molten extrusion end connects to the mold gate, allowing molten material to enter the mold and produce spherical products. These spherical products require polishing using sandpaper. Selecting the appropriate grit sandpaper, generally starting with a coarser grit (e.g., 120-180 grit), allows for preliminary polishing of the ball's surface, removing obvious imperfections and uneven areas. If a large number of spherical products need polishing, this significantly reduces polishing efficiency, and purchasing a ball mill directly increases production costs. Utility Model Content
