Resin pellets are blended with colorant pellets and regrind, then processed through a mold and press machine. Unfinished products are degated to remove seams, have attachments inserted, and are drilled, if necessary. Next, parts are patched and sanded. Finally, the part undergoes finishing operations including nickel coating, spray fill application, and top coat application. The team's report, detailing findings and recommendations, indicated that the majority of waste was generated in the mold and press machines but that the greatest savings could be obtained by utilizing electrostatic spray equipment in the finishing department to reduce (by 28%) the amount of paint solids waste generated. 收起
