公路界碑模具的应用是根据目前对公路界塑料模具的需求而言的，因为公路界预制块的制作离不开模具的支持，有而质量好的模具与质量差的模具在价格方面相差很多，使用次数不同。公路界碑模具属于特定领域使用的塑料模具，该模具的应用很好的填缺了公路建设缺少模具的现象，而且每根公路界塑料模具的使用次数可到100次，这样折合到每根公路界预制块上的成本就非常少了。在与百米桩塑料模具，里程碑塑料模具搭配使用的过程中，公路界塑料模具是用量大的一类。The application of highway boundary pillar molds is based on the current demand for plastic molds in the highway industry, because the production of prefabricated blocks in the highway industry is inseparable from the support of molds, and there is a lot of difference in price and use times between molds with good quality and molds with poor quality. The highway boundary pillar mold belongs to the plastic mold used in a specific field. The application of the mold can well fill in the lack of mold in highway construction, and the use times of each highway boundary plastic mold can be up to 100 times, so the cost converted to each highway boundary precast block is very small. In the process of matching with 100m pile plastic molds and milestone plastic molds, the plastic molds in the highway sector are used in large quantities.
