Foam granulator takes you out of the mud of nowhere
Foam granulator products occupy a larger proportion in the field of hollow products. The process is to extrude several different raw materials into a hollow product through a composite die to achieve a container of C02, O2, or gasoline. Barrier properties. The adaptability and combination of foam granulators are the prerequisite for ensuring the quality of multilayer coextruded hollow plastic products. The developer must first thoroughly understand the objects processed by the developed multi-layer co-extruded hollow plastic molding machine (including the features of the products, the materials of each layer of the product, the bonding properties between the layers, and the properties of the tackifier). , and then design the extruder to adapt to the desired plasticized material object, determine the number and type of extruder required. Waste foam pelletizers should be able to adapt to different flow rates, plasticize different materials, and have higher productivity than standard extruders. The structure of the screw and barrel varies with the nature of the material being processed. Each extruding device should be equipped with an automatic controlled dosing hopper to accurately control the dosing amount. Product development focus: 0.2L-1L cosmetics and household sanitary cleaners 2-3 layers co-extruded hollow plastic molding machine; 4-6 layers co-extruded automotive fuel tank hollow plastic molding machine; 220L large-scale multilayer co-extruded hollow Plastic molding machine. The control of the temperature during granulation is a very important foam granulator. The temperature of the upper screw can be set at about 200 degrees at the time of starting, and the temperature of the lower screw can be set at about 160 degrees. This is in the case of producing dry material, and the temperature is adjusted by looking at the extruded material. Boot, this can avoid the damage of the machine caused by insufficient temperature. Change the filter, so that the quality and transparency of the particles can be guaranteed. The filter can be selected between 40-100 meshes according to the product quality requirements; the number of filters is more High, the cleaner the impurities are filtered. Cooling water temperature control: ensure that the cut particles have a certain temperature to evaporate the moisture on the surface of the particles.
