选择理想的护坡钢模具结构在于确定必须的成型设备，理想的型腔数，在可靠的条件下能够使护坡钢模具本身的工作满足该塑料制件的工艺技术和生产经济的要求。
The ideal structure of the well cover die is to determine the necessary forming equipment and the ideal number of cavity. Under absolutely reliable conditions, the work of the well cover die itself can meet the technological and economic requirements of the plastic parts.
对塑料制件的工艺技术要求是要保证塑料制件的几何形状，表面光洁度和尺寸精度，生产经济要求是要使塑料制件的成本低，生产效率高，模具能连续的工作，使用寿命长，节省劳动力
The technological requirements for plastic parts are to ensure the geometrical shape, surface finish and dimensional accuracy of plastic parts. The economic requirements for production are to make plastic parts low cost, high production efficiency, continuous work of moulds, long service life and labor saving.
护坡钢模具在模具总量中的比例还将逐步提高，整个行业正迎来前所未有的发展机遇。
The proportion of well cover mould in the total amount of mould will gradually increase, and the whole industry is facing unprecedented development opportunities.
各行各业特别是市政方面，对护坡钢模具的需求将会越来越大，对要求也会越来越高，模具行业为适应市场，需要内修外炼，掌握核心技术，优化护坡钢模具产品，逐步扩大企业影响力、
In order to adapt to the market, the mould industry needs internal repair and external refining, master the core technology, optimize the product of the well cover mould, and gradually expand the influence of the enterprise.
