A safe processing site needs to be selected for the processing of flow channel molds. The manufacturing and processing are completed according to the scientific production mode. In addition, there are great differences between steel molds and plastic molds. First, the production effect is different during processing. If there are no additional requirements for the processing and production of steel molds, the prefabrication method can be selected for production, This processing method is applicable to most molds and can ensure the integrity of prefabricated parts. This processing method is also obtained through scientific experiments. Workers are easy to operate and easy to produce. When making, the mold must be assembled first. The length of the chute mold is about 80 cm to 1.2 m, which is relatively large. In order to save space during transportation and storage, all the molds will be disassembled and checked first, Check whether there is rust. Then, it is necessary to fill the mortar into the mold through the pipe. In this step, it is necessary to ensure that the water trough mold is placed stably. Then, the vibrating rod is inserted into the mud, and the vibration position is constantly adjusted during vibration, so that the bubbles in the mud can be discharged more cleanly. After the bubbles float, wait for the mud to dry, The disassembled mold shall be cleaned and stored in time.
