擠出機(jī)頭伸入到模腔中，隨著每組模具的閉合就形成了波紋管的成型腔，擠出機(jī)把熔化的聚乙烯塑料注入到模具中，溶液會(huì)迅速填充到紋路中，隨著模具向前移動(dòng)模具中的冷卻系統(tǒng)會(huì)讓波紋管硬化成型，每對(duì)模具會(huì)自動(dòng)打開脫模，模具向前移動(dòng)繼續(xù)循環(huán)成型波紋管。 </p> <p> 而脫模后的波紋管就成型了，還要用水冷淋將塑料完全硬化，這根長長的波紋管會(huì)不斷的增長。通過幾個(gè)帶齒的轉(zhuǎn)盤旋轉(zhuǎn)，在波紋管的四周凹槽處打孔，一般都會(huì)打方孔這樣能增加排水面積。波紋管表面用一層濾布包裹并熱壓粘緊，這樣可以防止排水溝上的孔洞被堵塞。然后，將水管按一定長度切斷并纏繞在卷軸上，并用繩子固定，再用塑料薄膜纏繞就可以直接出廠了。每一個(gè)產(chǎn)品都要進(jìn)行抽樣測(cè)試，通過壓縮強(qiáng)度測(cè)試可以確保管道在承重時(shí)不會(huì)發(fā)生彎曲。

耐壓力是波紋管性能的一個(gè)重要參數(shù)。波紋管在常溫時(shí)，波形上不發(fā)生塑性變形所能承受的比較大靜壓力，即為波紋管的比較大耐壓力在一般情況下，波紋管是在一定的壓力（內(nèi)壓或外壓）下工作的，所以它在整個(gè)工作過程中必須承受這個(gè)壓力而不產(chǎn)生塑性變形。波紋管的耐壓力實(shí)際上屬于波紋管的強(qiáng)度范疇。計(jì)算的關(guān)鍵是應(yīng)力分析，也就是分析波紋管管壁上的應(yīng)力只要波紋管管壁上比較大應(yīng)力點(diǎn)的應(yīng)力不超過材料的屈服強(qiáng)度，波紋管所受的壓力就不會(huì)達(dá)到其耐壓力。同一波紋管在其它工作條件相同時(shí)，受外壓比受內(nèi)壓時(shí)的穩(wěn)定性要好，所以，受外壓作用時(shí)的比較大耐壓力比受內(nèi)壓時(shí)高。當(dāng)波紋管兩端固定，如果在其內(nèi)腔通入足夠大的壓力時(shí)，波紋管波峰處有可能爆破損壞。波紋管開始出現(xiàn)爆破時(shí)波紋管內(nèi)部的壓力值稱為爆破壓力。爆破壓力是表征波紋管比較大耐壓強(qiáng)度的參數(shù)。波紋管在整個(gè)工作過程中，其工作壓力遠(yuǎn)小于爆破壓力，否則波紋管將破裂損壞。當(dāng)波紋長度小于或等于外徑時(shí)，其計(jì)算結(jié)果和實(shí)際爆破壓力很接近；對(duì)細(xì)長型波紋管其實(shí)際爆破壓力要低很多。爆破壓力大約為允許工作壓力的3~10倍。
