Alipainemuovausta

Alipainemuovausta, also known as vacuum forming, is a manufacturing process where a heated plastic sheet is drawn and formed over a mold using vacuum pressure. This technique is widely used for producing a variety of parts and products from thermoplastics. The process begins with a sheet of plastic, which is heated to a pliable state. Once the plastic reaches the correct temperature, it is draped over or placed into a mold. A vacuum is then applied, which sucks the air out from between the plastic sheet and the mold surface. The atmospheric pressure then forces the softened plastic tightly against the mold, conforming it to the mold's shape. After the plastic has cooled and solidified, it is removed from the mold. The mold can be made from various materials, including wood, aluminum, or composite materials, and can be either positive (a shape that sticks out) or negative (a cavity). Alipainemuovausta is a relatively cost-effective method for producing prototypes, short runs, and large-scale production of items such as packaging, automotive components, boat hulls, and displays. The complexity of the final part is largely determined by the complexity of the mold.
