Plastic fruit crates and plastic Vegetable crates are manufactured using a complex method called injection molding. An injection mold is a machine that converts plastic raw materials into usable items. In most plastic injection molding machines, a hopper receives raw material and directs it into a delivery tube. The screw inside the conveying channel will turn which, when combined with heat, will help to liquefy the plastic in preparation for the mold.

　　When filled with molten plastic, the mold is a carefully crafted chamber that gives the molten plastic its shape. Under strict temperature control, the newly manufactured plastic (which would be a plastic fruit and vegetable bin in this case) cools and hardens. After the plastic crate has cured, it is cleaned to remove any defects before shipping or sending it for further processing.

　　Fruit and vegetable plastic boxes have played an important role in the agricultural industry, and almost every farmer now owns many of these boxes. It is their numerous advantages and applications that make them so popular.
