快速公路防撞墙模具我国模具行业在荆棘中不断前进，技术支持，更多技术支持我国模具行业在荆棘中不断前进，我国防撞墙模具行业在荆棘中不断前进，为保证防撞墙模具零件的产量和模具外形尺寸稳定，在大规模生产模具时应采用高性能材料制造，并对材料外观进行低真空表面强化处理，其次模具形状复杂，精度要求高，制造周期长，因此模具生产过程中防撞墙钢模具目前大幅增长，促使模具行业向前迈进了一大步。从模具的选择方面来看，必须选择有质量保证的，以质量为中心，提高模具的寿命等，考虑模具的室形、分型面、浇注位置和方式、排气位置等，对模具的精度、形状、复杂性、物理性质有重要影响。

Expressway anti-collision wall mold China's mold industry is advancing in the thorns, technical support, more technical support, China's mold industry is advancing in the thorns, and China's national defense wall striking mold industry is advancing in the thorns

It is proved that the output of the anti-collision wall mold parts and the overall dimension of the mold are stable. In the large-scale production of the mold, high-performance materials should be used, and the material appearance should be subject to low vacuum surface strengthening treatment. Secondly, the mold shape is complex and the precision is high

High requirements and long manufacturing cycle, so the anti-collision wall steel mold in the mold production process has increased significantly, which has promoted the mold industry to take a big step forward. From the aspect of die selection, it is necessary to select the one with quality assurance to

Quality as the center, improve the service life of the die, and consider the chamber shape, parting surface, pouring position and mode, exhaust position, etc. of the die, which has an important impact on the accuracy, shape, complexity and physical properties of the die.
