复合井盖是采用复合材料制作的井盖，它的综合性能是各种材料的井盖中是属一属二的，下面是详细的分析数据：

1 工艺方面:属于厚壁注塑，这种方式无论是在国内还是在国际上的同行业中都属于一个技术难点。在失放应力时，就易开裂、易气泡，收缩变形大，而且几何尺寸难控制。

2 与其它复合材料对比：属于厚壁注塑，这种方式无论是在国内还是在国际上的同行业中都属于一个技术难点。在失放应力时，就易开裂、易气泡，收缩变形大，而且几何尺寸难控制。

3 井盖表面需要打孔时的优势：井盖要有一定的刚性防止提钻时板材颤动，又要有一定弹性，当钻头下钻接触的瞬间立即变形，使钻头精确地对准被钻孔的位置，保证钻孔位置精确

通上以上三方面可以看出，复合井盖无论是在工艺方面，与其它材料对比方面还是后期的二次加工方面都有着明显的优势，所以得到了越来越广泛的应用。

Composite covers are made of composite material covers, its overall performance is covers various materials is a genus of two , the following is a detailed analysis of the data :

A process : the part of thick-walled injection molding, in this way , whether at home or in the same industry in the international arena belongs to a technical difficulty . Put stress on the loss , it is easy to crack , easy bubbles, shrinkage deformation, and geometry difficult to control.

2 Comparison with other composite materials : thick-walled injection molded part , in this way , whether at home or in the same industry in the international arena belongs to a technical difficulty . Put stress on the loss , it is easy to crack , easy bubbles, shrinkage deformation, and geometry difficult to control.

3 covers the surface of the punch when needed advantage: the covers have a certain rigidity to drill the plate to prevent vibration, but also have a certain flexibility , the moment when the drill bit contacted immediately following the deformation , so that the drill precisely aligned position is drilled ensure accurate drilling position

Pass on these three aspects can be seen both in the process of composite covers , the comparison with other materials or secondary processing aspects of late have a distinct advantage , so get a more widely used .
