termoformaus

Thermoformaus is a manufacturing process used to shape plastic materials. It involves heating a plastic sheet until it becomes pliable, then stretching or forcing it over or into a mold. Once the plastic cools and solidifies, it retains the shape of the mold. This technique is widely used for producing a vast array of products, from disposable cups and food packaging to automotive parts and medical devices.

The process begins with a flat sheet of thermoplastic material. This sheet is heated uniformly, typically using radiant heaters, to a specific temperature that allows it to be easily deformed without melting or degrading. Once heated, the plastic sheet is immediately positioned over a mold. Various methods are employed to press the plastic against the mold's surface, including vacuum forming, where a vacuum is applied to pull the plastic into the mold cavity, and pressure forming, which uses compressed air to force the plastic into the mold. Mechanical forming, where a plug or male mold pushes the plastic into the female mold, is another common technique.

After the plastic has conformed to the mold's shape, it is cooled, often with air or water, to solidify and maintain its new form. Finally, the formed part is ejected from the mold and any excess material is trimmed away. The simplicity and cost-effectiveness of thermoformaus make it a popular choice for mass production.
