How to production high quality sushi box?
The production process of high quality sushi box typically involves the following steps:
-
Raw material preparation: First, plastic materials need to be prepared. Common plastic materials used include polypropylene (PP), polyethylene (PE), etc. These materials are usually provided in the form of pellets, powder, or sheets.
-
Plastic melting: The selected plastic raw materials are placed into an injection molding machine. Through heating and melting processes, the plastic materials are transformed into a molten state. The molten plastic becomes highly malleable and can be further processed and shaped by the injection molding machine.
-
Mold design and fabrication: Based on the design requirements of the sushi box, corresponding molds are created. Molds are typically made of metal materials and have the shape and size of the sushi box.
-
Injection molding: The molten plastic is injected into the mold. With the high pressure and temperature applied by the injection molding machine, the plastic fills the cavities in the mold and gradually cools and solidifies.
-
Demolding and trimming: After cooling, the mold is removed from the injection molding machine, and the formed sushi boxes are taken out of the mold. Trimming and removal of any excess plastic material may be performed to obtain the final sushi box product.
-
Quality inspection and packaging: The finished sushi boxes undergo quality inspection, including visual inspection and dimensional measurement. Qualified sushi boxes are cleaned and packaged, preparing them for shipment.
It's important to note that there may be variations in manufacturing processes among different manufacturers and production methods. However, the above steps generally serve as the basis for producing plastic sushi boxes.
