众所周知，路沿石钢模具乃用钣金钢板制成，虽然使用寿命长，善于野外生产，而且增加脱模次数。而好的塑料模具由聚丙烯制成，较之钢模具使用寿命大大降低，脱模也需谨慎。
As we all know, the road edge stone steel mold is made of sheet metal plate, although it has a long service life, is good at field production, and increases the number of demoulding. The good plastic mold is made of polypropylene, which can greatly reduce the service life of steel mold, and the demoulding should be cautious.

但是为什么路沿石钢模具一直不能独领风骚呢？是什么原因导致路沿石钢模具一直不能超越塑料模具而只能互补。
But why can't the road edge stone steel mold always lead the way? What is the reason that the stone steel mold of the road edge can not surpass the plastic mold and can only complement each other.

大家忽略了一个原因，那就是美观。现代社会众人越来越注重美观而实用的东西，先是美观后是实用，对于模具也不例外，
There is one reason that people have overlooked, that is, beauty. In modern society, people pay more and more attention to beautiful and practical things. First, they are beautiful, and then they are practical. Mold is no exception,

钢模具虽然比塑料模具耐用，但是其花纹、样式却没有塑料模具那么种类繁多。这也是导致路沿石钢模具不能独领风骚的直接原因。
Although the steel mold is more durable than the plastic mold, its pattern and style are not as diverse as the plastic mold. This is also the direct reason that the road edge stone steel mold can not lead the way.
