Both extruders and flat vulcanizers are equipment for processing rubber into the shape of rubber products. The difference lies in the different molding processes of the products and the different production methods of the equipment. Some products can be produced by extrusion production process, and also can be produced by die-casting molding process such as a plate vulcanizer. However, some products can only be extruded with a rubber extruder, and some products can only be processed and formed by a flat vulcanizing machine. We have to compare which production process has lower production cost and which production efficiency is higher to select the production process. For example, in the extrusion production of rubber sealing strips, the products are extruded by a rubber extruder machine and then vulcanized in a hot air vulcanization box. Finally, after cooling with water, the single-extrusion sealing strips we need can be obtained. This production process can form an automated production line, which can continuously produce the sealing strips we need. The amount of finished products and the amount of labor required are many times higher than the advantages of the die-casting production process.
However, some products are not suitable for production by extrusion production process, such as some special-shaped rubber pads, or the production of some rubber pads cannot be extruded by a rubber extruder. Some products are extruded by a rubber extruder and then require various processing to obtain the finished product. In that case, the production cost will be much higher than the product produced by the flat vulcanizing machine. Therefore, the advantages and disadvantages of these two production processes coexist, and we need to choose according to specific products. In the production process, the rubber extruder is only responsible for the extrusion and molding of the product. After the product is extruded and produced, it needs to go through the vulcanization equipment for final shaping and vulcanization. The plate vulcanizing machine is integrated in the production of molding and vulcanization. It can also be said that the plate vulcanizing machine is produced by the principle that the fluidity of the rubber is increased after the temperature is raised, and then the high temperature vulcanization can be finalized. When we select the production equipment of the product, we must make a targeted selection according to the specific product, and choose the production process that is most suitable for the production of our products.
