復(fù)合井蓋是采用復(fù)合材料制作的井蓋，它的綜合性能是各種材料的井蓋中是屬一屬二的，下面是詳細的分析數(shù)據(jù)：

1 工藝方面:屬于厚壁注塑，這種方式無論是在國內(nèi)還是在國際上的同行業(yè)中都屬于一個技術(shù)難點。在失放應(yīng)力時，就易開裂、易氣泡，收縮變形大，而且?guī)缀纬叽珉y控制。

2 與其它復(fù)合材料對比：屬于厚壁注塑，這種方式無論是在國內(nèi)還是在國際上的同行業(yè)中都屬于一個技術(shù)難點。在失放應(yīng)力時，就易開裂、易氣泡，收縮變形大，而且?guī)缀纬叽珉y控制。

3 井蓋表面需要打孔時的優(yōu)勢：井蓋要有一定的剛性防止提鉆時板材顫動，又要有一定彈性，當(dāng)鉆頭下鉆接觸的瞬間立即變形，使鉆頭精確地對準被鉆孔的位置，保證鉆孔位置精確

通上以上三方面可以看出，復(fù)合井蓋無論是在工藝方面，與其它材料對比方面還是后期的二次加工方面都有著明顯的優(yōu)勢，所以得到了越來越廣泛的應(yīng)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 .
