The molding process of indoor sauna rooms is a crucial step in transforming design concepts into a stable, operational physical space. This process integrates multiple steps, including material processing, structural fabrication, system integration, and quality control. It must meet the stringent requirements of high-temperature and high-humidity environments while also ensuring safety, comfort, and aesthetics. Standardized molding processes not only guarantee product quality but also serve as an important indicator of the industry's professional development.
In the material pretreatment stage, the core focus is on improving the weather resistance and dimensional stability of wood and other substrates. Commonly used natural woods such as red cedar and hemlock undergo rigorous selection and conditioning treatment. This involves using a constant temperature and humidity environment to reduce the moisture content to a range suitable for the local usage environment, thereby minimizing the risk of later deformation and cracking. Subsequently, surface sanding and anti-corrosion and insect-proof coatings are applied, preserving the natural texture while enhancing moisture and antibacterial capabilities. Metal fittings require degreasing, rust removal, and high-temperature passivation treatment to ensure lasting corrosion resistance in humid and hot environments.
Structural molding primarily utilizes modularization and on-site assembly. During the factory prefabrication stage, wall, ceiling, floor, and door modules are fabricated according to design drawings. CNC cutting ensures dimensional accuracy, and mortise and tenon joints or high-strength connectors enhance the strength of the assembly. Some high-end products utilize a lamination composite process, combining the advantages of different materials. For example, a composite of an inner high-density insulation layer and an outer decorative layer can improve thermal insulation and aesthetics while reducing weight. On-site assembly is carried out by experienced technicians who sequentially complete the frame construction, panel fixing, and sealing, paying particular attention to moisture prevention and thermal bridge interruption at the joints to maintain a uniform and stable internal thermal environment.
Heating and functional system integration are key technical aspects of the molding process. Heating elements are positioned and installed according to heat distribution simulation results to ensure uniform radiation coverage of the usage area; steam or wet steam components undergo pre-construction pipe connections and sealing tests to prevent leaks during operation. Temperature control, ventilation, and safety protection devices are integrated into the main control system during the final assembly stage and online debugging is performed to verify the effectiveness of sensor responses, actuator actions, and abnormal protection logic.
Post-molding finishing processes include overall grinding, edge rounding, anti-slip treatment, and cleaning inspection. All exposed surfaces must meet the standard of a smooth, warm touch and be free of burrs and sharp edges. Before leaving the factory, they must undergo a certain period of simulated operating condition testing to expose potential defects and correct them promptly.
Overall, the molding process of indoor sauna rooms is a systematic engineering project spanning materials science, structural engineering, and electromechanical control. Only by implementing precision machining and strict quality control in every process can we ensure the long-term stable operation of the finished product in complex environments, providing users with a safe, comfortable, and high-quality experience. This also lays a solid foundation for process standardization and technological upgrading in the industry.
