For railway precast yards, the mould is no longer judged only by its first pouring result. Buyers now ask more about how many times it can be used, how the side plates stay in position, and whether the finished wall section keeps the same size after daily work. In current projects, 300 x 500 mm protective wall parts and 200 x 400 mm cable trough walls are common references, so a stable forming face and clear rebar holes save time on site.
Manufacturers are also putting more effort into drawing checks before production. Q355 or Q235 steel, 14 to 20 mm plate thickness, joint tolerance within 0.2 mm and a 2 degree release slope are practical points that customers often review. A mould that is easy to clean, lift and assemble can help a precast team keep daily output around 20 to 25 pieces without changing the working method too much.
