What manufacturing process is used to make plastic cups?

Disposable plastic cups are usually produced by plastic cup making machines, and usually the cups we see are generally divided into three materials: PP PS PET. PP cups have high heat resistance, so they can withstand high temperatures of up to 100°C and are suitable for boiling water. PET cups are not suitable for hot water ‌, especially long-term use in high temperature environments may lead to the precipitation of harmful substances, which poses a potential threat to human health.

‌

Sinoplast's latest plastic cup making machine, with fully automatic servo drive and PLC control system, are ideal for the production of disposable cups, plates, bowls, trays and other plastic packaging products. ‌

Its working principle is to transport the plastic sheet to the heating box of the machine through the feeding rack for heating, when the plastic sheet is heated to a specific temperature, it is formed into a specific shape by the mold, and it becomes the final product after cutting. Under the premise that the customer's factory has a plastic sheet extruder, the excess waste after the production of the plastic cup machine can be crushed again with the new plastic particles by the crusher, and the two can be mixed again by the extruder to produce new sheets.
