In order to better ensure the quality of the produced concrete precast blocks, we should choose to use better concrete slurry to process and manufacture the crossing sign pile mold. Today, our factory will introduce to our customers how to use the mold for production. First of all, the mould of crossing sign pile is made of steel plate material as a whole, and its overall design is that the steel plate needs to be fixed with screws. Workers should check the whole set of mould before use, so as to ensure that there is no problem in mould quality and will not affect the production and use of mould. Secondly, after the mold is assembled, we should use the release agent to brush its surface, so that the concrete slurry will form a certain gap with it without mucous membrane, which can also ensure that the mold can be removed quickly during demoulding, and the surface of the concrete block will not be damaged. After that, the concrete slurry is poured into the crossing sign pile mold. The action should be as slow as possible. Do not inject too much air to prevent more cracks on the surface of the produced concrete block and poor forming effect. If there is a vibrating platform, it can also be vibrated, so that the air inside can be fully discharged.
