lángpolírozást

Lángpolírozás, also known as flame polishing, is a surface finishing technique used to smooth and improve the appearance of certain materials, most notably plastics like acrylic and polystyrene. The process involves briefly exposing the surface to a controlled flame, typically generated by a gas torch. The intense heat melts the outermost layer of the material, causing microscopic imperfections, scratches, and tool marks to flow out and disappear. As the molten material cools and solidifies, it forms a smooth, glossy, and optically clear surface.

The key to successful lángpolírozás lies in precise control of the flame and its movement. The torch must be moved rapidly and consistently across the surface to avoid overheating or burning, which can deform or discolor the material. The distance between the flame and the material is also critical. Too close, and the material will melt excessively or char; too far, and the heat will not be sufficient to achieve the desired smoothing effect. Different types of gases, such as propane or acetylene, can be used, each with varying flame temperatures and characteristics.

Lángpolírozás is particularly effective for creating sharp, polished edges on cut plastic components. It is often employed in applications where a high degree of transparency and aesthetic appeal is required, such as in display cases, lenses, and decorative elements. While efficient, it is a technique that demands skill and practice to master. Improper application can lead to irreversible damage to the workpiece.
