高速护坡模具选材
Material selection for high speed slope protection mold
高速护坡模具一般都是根据尺寸，规格来决定选材的，我们经常使用的模具一般都是工程聚丙烯pp为原料，有一些特殊尺寸的模具选用钣金钢模具，这种钣金钢模具可以拆卸，再使用中方便简单，塑料模具适合大数量的生产提高每天的生产量，同时塑料模具可以回收再次利用，节省资源。这些护坡模具都是选用优质的工程聚丙烯pp为原料，专业是适应于高速高铁上，拥有很好的市场前景。
The high speed slope protection mold is generally based on the size and specification to determine the material selection. The moulds we often use are generally engineered polypropylene PP as raw materials. Some special sizes are used to choose sheet metal steel die. This kind of metal die can be dismantled, it is convenient and easy to use. The plastic mould is suitable for large quantity of production. Daily production, while plastic mold can be recycled and used again to save resources. These revetment moulds are made of high quality engineering polypropylene PP as raw materials, and the specialty is adapted to high speed rail and has a good market prospect.
