nedvesöntéses

Nedvesöntéses refers to a manufacturing process, specifically a type of casting or molding technique. The term, originating from Hungarian, literally translates to "wet casting" or "wet pouring." It describes a method where a liquid or semi-liquid material is introduced into a mold that is either already wet or designed to be kept moist during the process. This contrasts with dry casting methods where the mold and casting material remain dry.

The primary purpose of the "wetness" in nedvesöntéses can vary depending on the specific application and materials used. In some instances, moisture can act as a lubricant, facilitating the flow of the casting material into intricate mold details and preventing it from sticking. It can also help in controlling the setting or curing time of certain materials, allowing for a more controlled solidification process. Additionally, moisture might be used to absorb excess heat generated during the exothermic reaction of some casting compounds, preventing thermal shock or degradation of the mold or casting.

Nedvesöntéses is employed across various industries, including ceramics, concrete production, and certain polymer molding applications. The specific implementation involves preparing the mold, often by wetting its surfaces or filling it with a liquid medium, and then introducing the casting material. The subsequent steps involve allowing the material to cure or solidify, often under controlled humidity or temperature conditions, before demolding. The success of the nedvesöntéses process relies on careful control of material properties, mold design, and environmental factors like moisture levels.
