The invention discloses a brand
new production process for producing a plastic tray, which comprises the following steps of: pretreating raw materials, sequentially crushing, cleaning and
drying waste plastics, wood wastes or waste
textile raw materials through a
crusher, special cleaning equipment and a dryer, controlling the discharging
granularity of the raw materials to be 1-10mm, reducing the
water content to be 8-12%, and adopting a two-
station design, an electric
hydraulic pump drives ten 200-
ton and 150-mm-
stroke jacks to apply pressure to a mold, the mold is of a 90-degree flip type mold opening structure, and after a left tray mold trolley and a right tray mold trolley are in place, a patent accumulation type mold head extrudes molten materials into the mold according to the
extrusion amount set by a PLC. Therefore, according to the process, through alternate operation of two stations and multi-procedure integration, waiting and manual intervention are reduced, the forming precision is guaranteed through
synchronous control and independent supporting, equipment is simplified through low-pressure driving, faults are reduced,
modular design is suitable for unconventional tray production, and the problems that in the background technology, the production efficiency is low, and unconventional trays are difficult to prepare are effectively solved.
