Plastic basin production process

The invention belongs to the technical field of plastic product production, in particular to a plastic basin production process. The process comprises the following steps: multiple waste plastic bottles are prepared as raw materials, and the waste plastic bottles are cleaned and aired; the waste plastic bottles are put on a flattening module, and a rocking handle is rotated to flatten the waste plastic bottles; the flattened waste plastic bottles are fed in a heating box, and a box cover is covered to melt the waste plastic bottles in the heating box; a worktable is adjusted, and a table core,a first sleeve and a second sleeve are adjusted according to the sizes of plastic basins to be printed and the heights of basin bottom projections of the plastic basins; and after the plastic basinsare printed, the printed plastic basins are cooled, and then, the plastic basins are taken out. The plastic basin production process is improved through a PET plastic 3D printer; the waste plastic bottles can be used for quickly producing the plastic basins with recessed bottoms and different shapes; and waste resources are recycled, so that the environment pollution caused by the waste resourcesis reduced.
