Prefabricated shed column machine Introduction Pre-stress forming machine is a equipment for mechanized production from manual and semi-manual production to cement prefabrication plant. Once promoted, it quickly replaces the traditional “flip mold” and “drag mold” production. The production efficiency is high, the product density is good, the raw materials are saved, and the labor intensity of the workers is low. The molding machine produced by our factory has obvious features such as reasonable structure, novel design and simple operation, especially the large-area paving hardness alloy on the friction surface inside the machine, which improves the wear resistance of the equipment, and wears the bearing steel on the hole mandrel. The sleeve extends the life of the device while reducing maintenance costs.
