選擇理想的井蓋模具結構在于確定必須的成型設備，理想的型腔數，在****可靠的條件下能夠使井蓋模具本身的工作滿足該塑料制件的工藝技術和生產經濟的要求。
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.
對塑料制件的工藝技術要求是要保證塑料制件的幾何形狀，表面光潔度和尺寸精度，生產經濟要求是要使塑料制件的成本低，生產效率高，模具能連續的工作，使用壽命長，節省勞動力
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.
井蓋模具在模具總量中的比例還將逐步提高，整個行業正迎來前所未有的發展機遇。
The proportion of well cover mould in the total amount of mould will gradually increase, and the whole industry is facing unprecedented development opportunities.
各行各業特別是道路方面，對井蓋模具的需求將會越來越大，對要求也會越來越高，模具行業為適應市場，需要內修外煉，掌握核心技術，優化井蓋模具產品，逐步擴大企業影響力、
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.
