首先，模具具有表面光滑无瑕疵，制作出来的模具砖具有高硬度，其表面也比较好；其次模具的材料具有密度高、硬度高、压强高、重量轻、抗腐蚀、抗老化等优点。隔离墩模具材质分为两种，第一种是塑料模具，塑料模具是采用采用工程聚丙烯pp白色塑料制造而成，其特点质地轻、韧性很强、运输很方便等特点。第二是隔离墩钢模具，钢模具有很好的硬度，不仅耐性强，易脱模，而且使用寿命很长。

First of all, the mould has smooth surface and no blemish. The moulds made of the mould have high hardness and the surface is also good. Secondly, the material of the mould has the advantages of high density, high hardness, high pressure, light weight, corrosion resistance, anti-aging and so on. There are two kinds of materials for the isolation pier die, the first one is the plastic mold, and the plastic mold is made of Engineering polypropylene PP white plastic. Its characteristics are light weight, strong toughness, convenient transportation and so on. The second is the steel die of the isolating pier. The steel mould has good hardness. It is not only durable and easy to die, but also has a long service life.
