Szívóporolás

Szívóporolás, also known as dust suction or vacuum casting in English, is a technique used in manufacturing, particularly in the production of plastic components. It involves the use of a vacuum to draw molten plastic material into a mold. This method is often employed for creating intricate or complex shapes that might be difficult to achieve with traditional injection molding or other processes.

The process typically begins with a mold, which can be made from various materials such as silicone, metal, or even plaster, depending on the desired production volume and the type of plastic being used. The mold contains cavities that represent the final shape of the product. Molten plastic, often a thermoplastic or thermosetting resin, is prepared. The mold is then sealed, and a vacuum is applied. This vacuum creates a pressure differential, effectively sucking the molten plastic into every detail of the mold cavity, ensuring a complete fill.

Once the plastic has cooled and solidified within the mold, the vacuum is released, and the molded part is ejected. Szívóporolás is known for its ability to produce parts with high detail, good surface finish, and minimal internal stress. It is a versatile technique suitable for prototyping, small-batch production, and the creation of specialized components where precision is paramount. The choice of mold material and plastic type will influence the properties of the final product and the overall efficiency of the szívóporolás process.
