EPS Fully Automatic Intermittent Pre- foaming Machine

The machine adopts PLC full computer touch display screen control, which realizes the automatic cycle operation of the whole process of feeding, steam supply, temperature control, foaming and discharging, and quantitatively compresses and feeds, which is accurate and fast.• The machine adopts a fully enclosed stainless steel barrel for constant pressure foaming, which has high thermal efficiency, saves steam, shortens the curing process, and has a high foaming rate.• The machine adopts famous brand high-quality pneumatic components, reliable quality, easy operation, to ensure accurate control of temperature, so that the foamed beads have uniform density.• Made of stainless steel plate, good structure, easy maintenance, adjust the feed to achieve the required particle capacity. The 150 type can be foamed for primary and secondary foaming respectively. Before the EPS product is formed, it needs to go through the pre-release stage, so that the bulk density of the molded product can be better controlled in a lower range. Pre-molding reduces the density gradient during molding, allowing for uniform expansion molding. In the pre-release process, the beads containing the foaming agent are slowly heated to more than 90 °C and begin to soften, and the foaming agent in the beads is heated and vaporized to generate pressure to make the beads expand, and form complementary and connected bubbles (closed cells), the diameter of the bubbles after pre-release is about 80~150μm, there are about 0~550,000 small bubbles per cubic centimeter, and the thickness of the bubble wall is only 1~2μm. At the same time, the vapor also penetrates into the bubble hole that has been expanded, and when heating, the foaming agent can also seep out from the beads, so when pre-issued, the rate of vapor penetrating into the bubble hole should exceed the rate of the foaming agent seeping out from the bubble hole, so that the vast majority of the foaming gas stays in the bubble hole, so that the total pressure in the bubble hole increases, the foaming agent does not have time to escape in the bubble hole, the polymer is drawn in a rubber state, and its strength is enough to balance the internal pressure, so that the beads are pre-formed, the polymer is extended, and the beads are pre-expanded. The main function of the machine is to pre-send EPS raw materials, and the machine adopts all well-known brand accessories at home and abroad to ensure the stability and reliability of the machine. The barrel body and bottom of the barrel are made of high-quality stainless steel materials to ensure the service life of the machine. The international famous brand pressure reducing valve and proportional control valve are selected to make the foaming rate more stable and energy-saving. The machine can realize the convenient conversion of the first and second pre-hair, so that one equipment can pre-send the raw materials for many times, and the density of the raw materials can be 5~30KG/m³.
