路沿石塑料模具的質量與制作它的原材料的品質有著很大的關系的，我們生產的時候保證使用的是新的塑料，不要在里面混入回收的粉碎塑料。
The quality of curbstone mold has a great relationship with the quality of raw materials. When we produce, we guarantee to use new plastic, and do not mix recycled crushed plastic into it.
使用這種原料制作出來的模具表面會有很多的小黑點，表面也不夠光滑，而且它是非常容易老化的，使用的期限較短。
There are many small black spots on the surface of the mould made of this kind of raw material, and the surface is not smooth enough. Moreover, it is very easy to be aged and has a short service life.
然后就是我們生產的模具的壁的厚度，如果壁的厚度較大的話，它的耐磨性就會比較好，因為我們在使用的時候是非常容易對模具的表面造成磨損的，這樣對模具造成的傷害是比較大的。
Then the thickness of the wall of the mold we produced. If the thickness of the wall is larger, its wear resistance will be better, because we are very easy to wear the surface of the mold when we use it, so the damage to the mold is relatively large.
還有就是我們生產的模具的表面的加強筋的密度也會影響模具的質量，要想提高公路路沿石塑料模具的質量就需要我們增加加強筋的數量，這樣模具的抗壓性就會增強，不易發生變形。
In addition, the density of the reinforcing ribs on the surface of the molds we produce will also affect the quality of the molds. In order to improve the quality of the molds, we need to increase the number of reinforcing ribs, so that the compression resistance of the mold will be enhanced and deformation is not easy to occur.
