Yintoni i-Extrusion Molding?
Ukubumba i-Extrusion, okwakwaziwa njenge-extrusion kwi-processing yeplastiki, isebenzisa uxinzelelo lwe-hydraulic ukunyanzela izinto ngokubumba, ukudala amacandelo aqhubekayo eemilo ezahlukeneyo. Le nkqubo ibandakanya ukufudumeza impahla njengoko ityhalwa phambili nge-screw nge-barrel, okubangelwa ukubunjwa kweeprofayili eziqhubekayo okanye i-semi-products. Ukubumba i-Extrusion, itekhnoloji yamandulo ekusetyenzweni kwepolymer, iye yavela kule minyaka ili-100 idlulileyo yaba yindlela esebenza kakuhle kakhulu, eqhubekayo, enexabiso eliphantsi enokusetyenziswa ngokubanzi. Ngoku yeyona ndlela isetyenziswa kakhulu kwishishini lokulungisa i-polymer ngenxa yokuguquguquka kwayo, amazinga aphezulu emveliso, kunye nokuguquguquka.
Iinkqubo ezisisiseko kwi-Extrusion Molding
1. Ukutya
Izinto zeplastiki zondliwa kwi-hopper kwaye zihamba kwi-screw channels phantsi komxhuzulane okanye ngoncedo lwe-feeder, ukuqhubela phambili ukuya kwintloko yokufa.
2. Ukuhambisa
Njengoko iplastiki ingena kwi-screw channel, iqhubela phambili kunye nokujikeleza kwe-screw nganye. Elona nqanaba lokuhanjiswa lixhomekeke kwimikhwa yokukhuhlana yeplastiki ngokuchasene nombhobho kunye nesikrufu. Ukuxhatshazwa okuphezulu kunye ne-barrel okanye i-friction ephantsi kunye ne-screw kwandisa ukuhamba phambili kweplastiki.
3. Uxinzelelo
Uxinzelelo lubalulekile ekubumbeni i-extrusion. Iplastiki yi-conductor engafanelekanga yokushisa, kwaye naziphi na izikhewu phakathi kwamaqhekeza zinokuthintela ukuhanjiswa kobushushu, okuchaphazela izinga lokunyibilika. Ukunyanzeliswa kunceda ukukhupha iigesi kwizinto eziphathekayo, ukukhusela iziphene, kunye nokuqinisekisa ubuninzi bemveliso ngokugcina uxinzelelo lwenkqubo ephezulu.
4. Ukunyibilika
Ngokunyuka koxinzelelo, unxibelelwano lweplastiki oluqinileyo olushukumayo kunye nokukhuhla eludongeni lombhobho oshushu, lwenza ifilimu encinci enyibilikayo. Lo mboniso bhanyabhanya ukhunjulwe sisikrufu xa sihamba, siqokelelana phambi kweenqwelomoya ezisijiva kwaye zenze ichibi lokunyibilika.
5. Ukuxuba
Ngaphantsi koxinzelelo oluphezulu, izinto eziqinileyo zihlanganiswe kwiplagi eshinyeneyo. Ukuxuba kwenzeka kuphela phakathi kweeleya zemathiriyeli etyhidiweyo, hayi ngaphakathi kwiplagi eqinileyo.
6. Ukudinwa
Ukungena komoya kubalulekile ukususa iigesi kunye nomphunga oveliswa ngexesha lenkqubo yokukhupha. Ukungenisa umoya okufanelekileyo kuqinisekisa umgangatho wemveliso yokugqibela ngokuthintela i-voids kunye neziphene.
