EPS automatic molding machine

EPS product molding is roughly divided into two categories, one is the use of plate forming machine to produce large-volume rectangular foam products, cut into plates, used as building insulation and decoration materials, municipal engineering, etc. The other category is foam boxes, packing boxes, etc. Although packaging products and plate products are different in terms of density and application, their molding machine mechanism is the same, that is, the maturation of expandable polystyrene beads fill the closed cavity, in a relatively short period of time the hot steam through the pores of the wall directly into the cavity, when heating, the foaming agent remaining in the EPS beads volatilizes, the beads are softened and expanded by heating, due to the limitation of the cavity, the expanded beads can fill all the voids, completely bonded as a whole, after cooling and shaping, the demoulding is foam plastic products. The molding of the product consists of two stages: steam heating and cooling and shaping. The pre-haired beads are heated by steam, and in about 20~60s of time, the air does not have time to escape, and the pressure generated by the heated expansion, at this time, the polymer is softened, and the pressure generated after the vaporization of the foaming agent, the beads expand again, and swell the bead gap and form a whole piece, form the foam plastic products with the same shape as the mold cavity, and make it shaped after cooling. The steel of the whole machine is made of well-known steel products, and the steam pipelines are all made of seamless steel pipes and aged, so that the equipment is safer and has a longer service life. The electric control part of the selection of well-known brands of electrical components at home and abroad, the combination of PLC and man-machine interface makes the operation more simple and accurate. Introduction of benzene board equipment • The machine is welded by high-quality section steel, and has undergone aging heat treatment, so that the machine has high strength, no deformation, and can withstand the expansion force of high-density products.• The machine adopts PLC full computer touch display screen control, so that the machine can open the mold, close the mold, feed, heat, heat preservation, vacuum cooling, and remove the mold to eject the finished product, so as to achieve automatic cycle operation.• The surface of the machine cavity is made of special aluminum alloy plate, which has high heat conduction efficiency, good tensile strength and long life.• The machine adopts foreign advanced and unique penetration heating molding process, and sets up high-pressure induced air suction, cooling, strong penetration, good adhesion, less steam, fast molding, low water content, to ensure that the product is consistent inside and outside.
