Molding Plastic Square Cup

Molding plastic square cups follows a similar process to molding other plastic cups. The key difference lies in the shape of the cup, which is square or rectangular instead of round. The process typically involves injection molding, which is a common method for producing plastic products in large quantities. The first step is to design the square cup and create a mold specifically tailored to its shape and size. The mold is typically made of steel or aluminum and consists of two halves, the core, and the cavity. The design of the square cup is incorporated into the mold, including any intricate details or features. The appropriate plastic material is selected based on factors such as desired properties, food-grade safety standards, and compatibility with square cup production. Common plastics used for square cups include polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET).
