PRODUCTION LINE

The sandwich panel production line is for the whole process of making EPS sandwich panels of different sizes.

The three basic components used in the manufacture of EPS panels are the EPS insulating core, metal skins and an adhesive that bonds the metal skin to the core.The EPS core of the panel is typically call S, commonly known as S-grade which has a high insulating value and a thermal capacity of 0.038 W/M.k and having a density of 20kg/cum.In general, the most commonly used metal skin is pre-painted mild steel. The steels typically have a nominal Base Metal Thickness of 0.59 mm, and have a protective coating of either zinc, also known as galvanizing or a mix of zinc and aluminum. If correctly designed, detailed, installed and maintained, either of these materials will satisfy the regulatory requirement for a fifteen year durability for external cladding climate, and where required can achieve a fifty year durability period. A typical coil of the pre-painted steel product used in the manufacture of EPS panels weighs up to 5 tonne, which gives a yield of approximately 800-900 m2 of the finished insulated panel.The adhesive used to bond the metal skins to the EPS core is typically a two-part, thermosetting polyurethane. When adhered correctly, the shear strength of the glue-to-core interface is stronger than the shear strength within the EPS core material. The three main process of manufacturing EPS panels are as follows:

 EPS sandwich Panel Production Process

The actual manufacture of the EPS panel is a mechanized process which bonds the metal skins to both sides of the sheets of EPS core material. Sheets of EPS, cut to the required thickness, are fed end-on-end into the laminating machine between coils metal. As the coils move through the process, they are progressively roll-formed to achieve the required surface profile and edge jointing details. A typical coil of metal has an initial width of 1260mm which results in an insulated panel of 1200mm module width. Subsequently, glue is applied and the metal skin and EPS core are bonded together under pressure. The final stage of this continuous process is to cut the finished panels to their required
