Habaynta tubbada badan ee lumenes Waxay u baahan tahay farsamayaqaannada inay isku geeyaan noocyo badan oo kala duwan oo ka baxsan iyo qalabka hoose.Iyadoo habkan liidata, waxay u badan tahay in extruders kala duwan ay dhamaantood ku jiri doonaan diyaarad isku mid ah, taasoo keentay wadooyin dheer oo qulqulaya, cadaadiska kor u kaca iyo kordhinta wakhtiga wax-qabadka.Marka loo eego habka hab-socodkan oo kale,loo baahan yahaytuubosaamiga lakabka kuma dhigma wax soo saarka ugu fiican ee extruder, taas oo keeni kartaaad u sarreeya ama hooseeyaxawaarihii xawaaruhu, iyo dheeraad soo saar tuubooyinkaoo leh qalab farsamo oo liita.

Rajada macaamiisha ayaa horseedaysa isticmaalka ballaaran ee nidaamka xakamaynta tira koobkan iyo kordhinta shuruudaha wax soo saarka ee wakaaladaha sharciyeynta.Si kastaba ha ahaatee, cabbirka in-line saxda ah eethinwdhammaanmedicaltbeeridayaa caqabad weyn ku ah soosaarayaasha qalabka caafimaadka.

Weli waxa jira wax aad u yar oo heerkulbeeg ah oo noqon karaloo isticmaaloin la naqshadeeyo tuubooyinka lumen-ka badan.Qalabka ugu badan ee la isticmaalo waa kuwa dhaqan ahaan loo isticmaalo samaynta tuubooyinka caafimaadka, sida polyamide (PA), elastomer thermoplastic (TPE), polyurethane (PU), polyvinyl chloride (PVC), iyo polyolefin (PE).Agabkaan waxa loo habayn karaa in lagu daro qaybaha dawooyinka ka saara, walxaha shucaaca, buuxinta, iyo/ama midabada.Si kastaba ha ahaatee, naqshadeeyuhu waa inuu tixgeliyo heerkulka habaynta, sifooyinka socodka iyo dhalaalidda maaddada walxaha.
