Foam is commonly used in fruit transportation and packaging of goods. Because of its good shock resistance, lightweight and low price, it is widely used in the packaging industry. The production process of the foam box is complex and requires high-temperature steam for foaming and molding, so it is necessary to use a steam generator for foam molding.
Close the mold filled with expanded foam raw material and put it into a steam box, then use a foam setting steam generator for steam heating, the steam pressure and heating time depend on the size and thickness of the foam box. The thicker, foam boxes or large and medium-sized foam boxes are usually directly foamed and molded by a foam molding machine.
The pre-expanded particles are injected into the mold cavity together with steam through the high-temperature steam delivery method, and the temperature is raised to successfully foam. During foam molding, the size and thickness of parts have different requirements on steam pressure, temperature and heating time, and the foaming of the foam molding machine requires multiple preheating and heating, and there are differences in the amount of steam each time under pressure. The foam forming steam generator can adjust the temperature and pressure according to the different needs of foam forming, which never serves the purpose of reducing the difficulty of foam forming.
It can be seen that by using a steam generator to generate a continuous and stable steam heat source, with sufficient steam and moderate dry humidity, this not only meets the production needs of the foam factory, but also improves production efficiency and benefits. Nobeth steam generator can automatically adjust the steam temperature and pressure according to the production process to ensure that it expands within a reasonable range, and can adjust the appropriate humidity according to different materials to ensure smooth foam production.
