The material used for the curb stone mold

The curb stone mold adopts engineering PP (polypropylene) raw material, which has good malleability, machinability, hardenability, hardenability and grindability, and also has small oxidation, decarburization sensitivity and quenching deformation cracking tendency.
All the raw materials used in plastic molds are first-class new materials, without crushing and recycling, so do not use the mold made of crushed recycled material on the market, the mold made of crushed recycled material has a short service life, easy to age and deform. The surface is uneven, and the cement parts are not easy to demold. Please purchase with caution.
