Shoe mold replacing wood: it is used for opening mold and proofing of large soles. It can be divided into hand carving and machine carving. Hand engraving requires moderate soft and hard. Machine engraving requires harder than hand engraving, but it cannot be too hard, because too hard becomes brittle and easy to collapse. On the other hand, if it is too soft, it will be planted with wood Xiao, and it will be difficult to walk. The most important thing is that the sand should be smooth and not deformed, and the size will not be reduced due to the high temperature during molding, such as the dehydration of traditional wood. After the product is processed and formed, the surface is smooth and the material is uniform without bubbles.
