Iindidi zeteknoloji yokubumba inaliti yeplastiki: Isitofu, i-Bi-injection, i-Co-Injection kunye nokuBunjwa ngaphezulu

Ukubumba inaliti yeplastiki yinkqubo yokuvelisa ukuveliswa kwamalungu ngokutofa izinto kwi-mold.

I-resin ekwimo yeegranule zeplastiki yondliwa nge-hopper ukuya kwi-cylinder (barrel) ngokufudumeza ngesikrufu sangaphakathi (i-Spindle) esinyibilikisa kwaye siyifake iplastiki iplastiki ngobushushu kunye nokukhuhlana emva koko iyifake phantsi koxinzelelo kwimingxuma ukungunda, apho ipholisa kwaye iqina kuqwalaselo lwemingxuma yokungunda

Ukususela ekucacisweni kweetafile, izitulo ukuya kwizihlanganisi zombane, i-Injection Molding ngokungathandabuzekiyo yenye yezona nkqubo zibalulekileyo zokwenziwa kwezixhobo zeplastiki kushishino. Iqulethwe ukunyibilika kwe-resin ukuyondla kwi-mold kunye nesimo seqhekeza, ukuvumela ukuba izinto zipholile kwaye zikhuphe isiqwenga esibunjiweyo.

Oko kukuthi, i-resin ekwimo yeegranules iyondliwa nge-hopper ukuya kwi-cylinder (barrel) ifudunyezwe nge-screw yangaphakathi (i-spindle) enyibilikayo kwaye ifake iplastiki ngeplastiki ngokutshisa kunye nokuxutywa kwaye emva koko iyifake phantsi koxinzelelo kwimingxuma. . yokungunda, apho ipholisa kwaye iqina kuqwalaselo lwemingxuma yokungunda.

Ukufezekisa ukuthungwa okwahlukeneyo kunye nokugqiba kukho izinto eziguquguqukayo ngaphakathi kwesitofu esibandakanya:

1. Ukubumba ngaphezulu: Isitofu sokubumba apho imathiriyeli itofwe kwindawo okanye kufakwe into efanayo okanye enye into.

I-2-step molding luhlobo lwe-over-molding apho ukufakwa kwenziwa kwizinto ezifanayo. Isitofu sesibini sinokugubungela yonke into efakiweyo okanye sihambe nje kwiindawo ezimbalwa ezikhethiweyo.

Ukugcwala inokuthi yenzeke kumatshini omnye kunye ne-carousel ejikelezayo okanye kumatshini wesibini.

2. Isitofu kabini: iyona ndlela ilula kakhulu yokubumba i-injection, yamacandelo amabini, ukusuka kwindawo yokujonga umatshini kunye nokubumba, apho i-cavity izaliswe ngaxeshanye kunye namacandelo amabini ahlukeneyo avela kumanqaku amabini ahlukeneyo. Ingxaki ngolu buchule kukuba xa ujova amacandelo amabini ahlukeneyo, umgca we-welding, oveliswa yintlanganiso yamacandelo axeliweyo, ungaphantsi kolawulo.
3. I-Co-Injection: yinkqubo apho iipholima ezimbini okanye ngaphezulu ezahlukeneyo zilaminethiwe kunye ngokubumba inaliti. Ezi polymers zinokufana, ngaphandle kombala okanye ubunzima, okanye zinokuba ziindidi ezahlukeneyo zeepolima. Xa kusetyenziswa iipolymers ezahlukeneyo, kufuneka zihambelane (zithengiswa) kwaye zinyibilike malunga nobushushu obufanayo.

Ezi ziguquko zenkqubo yokubumba zivumela ukuba kubekho iintlobo ezininzi zokugqiba, ukuhlobisa kunye nobuchule obusebenzayo.

Zonke ezi nkqubo ziza ngenjongo. Njengoko siphawula kakuhle, ukugqitywa kwiinqununu zeplastiki kunokwahluka ngokuxhomekeke kwinkqubo. Ukuba sifuna ukwenza iziqwenga ezisemgangathweni, okona kulungileyo kukugxila kwezi nkqubo zahlukeneyo, ngale ndlela, iintlobo ezingcono zamaqhekeza kunye nomgangatho ongcono unokufumaneka (kungekhona kuphela kwimiphetho, kodwa nakwimixholo yokuhombisa kunye nokusebenza)

Ukufumana okungakumbi malunga neentlobo ze iteknoloji yokubumba inaliti yeplastiki: isitofu, isitofu se-bi-injection, isitofu esidibeneyo kunye nokubumba ngaphezulu, ungandwendwela i-Djmolding e- https://www.djmolding.com/technology-application/ ngolwazi olungakumbi.
