What are the characteristics of kerb molds for cement products?

Mold is divided into soft mold and hard mold. The soft mold needs the support of the hard mold, and the kerb stone mold is simple in shape and suitable for mass production. It is best to loosen the concrete and press it with a press, which has high efficiency and large output. In the north, cement products are no longer used as kerbs, because kerbs will be damaged quickly due to freezing and thawing in winter. They all use granite as kerbs.
