    The cable trough mould plays an important role in the production of cement precast curbstone. Mold materials are mainly divided into plastic injection molding and cable trough mold molding. The material selection of the cable tray has a great influence on the quality of the cable tray.

    Some cable trough molds are made of composite resin materials, that is, the commonly referred BMC mainly uses unsaturated resin, glass fiber chopped, filament, plus some fillers, with reinforcement framework.

    The product has stable performance, strong temperature resistance, acid and alkali resistance, compression resistance, bending resistance, impact resistance and flame retardant. The price of the product is relatively higher than that of steel fiber reinforced concrete, recycled resin and polymerized composite, but it is cost-effective in terms of service life and product performance.


    It is generally thought that low temperature sealing is the result of the following three effects. Hydration reaction effect low temperature sealing is carried out in aqueous solution, which is the same as that of high temperature sealing. At present, most domestic manufacturers choose low temperature sealing technology.

    Generally, the production of cable trough requires the die to have a certain strength, toughness and wear resistance, which can meet the requirements of the die working environment, and has good malleability, machinability, hardenability, hardenability and grindability, so as to meet the process performance of the die.
