Kune nzira dzakawanda dzekuisa mota dzemapurasitiki molds, zvichienderana nenzira dzakasiyana dzezvikamu zvepurasitikikuumba uye kugadzirisa, vanogona kugoverwa muzvikamu zvinotevera.
1 – Jekiseni mold
Iyo yekuumba maitiro ejekiseni mold inoratidzwa nekuisa zvinhu zvepurasitiki mubhodhoro rinopisa remushini wejekiseni. Plastiki inodziya uye yakanyungudutswa, inosundirwa nescrew yemuchina wejekiseni kana plunger, uye inopinda mugomba rekuumbwa kuburikidza nemhuno uye yekudururira system, uye purasitiki inorapwa mugomba kuburikidza nekuchengetedza kupisa, kuchengetedza, uye kutonhora. Sezvo iyo yekudziya uye yekumanikidza mudziyo inogona kushanda mumatanho,jekiseni kuumbahaigone chete kugadzira zvikamu zvepurasitiki zvakaoma, asi zvakare kuve nepamusoro kugadzirwa kwekuita uye kunaka kwakanaka. Naizvozvo, kuumba jekiseni kunotora chikamu chikuru muzvikamu zvepurasitiki zvekuumba, uye majekiseni molds anodarika hafu yemapurasitiki ekuumba. Muchina wekuumba jekiseni unonyanya kushandiswa kuumba thermoplastics, asi mumakore achangopfuura unoshandiswawo zvishoma nezvishoma kuumba thermosetting mapurasitiki.
2-Compression mold
Compression molds anonziwo akadzvanywa rubber molds. Kuumbwa kwechiumbwa ichi kunoratidzwa nekuwedzera mapurasitiki mambishi akananga muvhu rakavhurika mold, wobva wavhara mold, mushure mekunge ipurasitiki yanyungudutswa pasi pechiito chekupisa nekumanikidza, inozadza gomba nekumwe kudzvanywa. Panguva ino, chimiro chema molecular epurasitiki chinoburitsa kemikari-cross-linking reaction, uye zvishoma nezvishoma inoomesa uye inogadzirisa chimiro. Compression mold inonyanya kushandiswa ku thermosetting mapurasitiki, uye zvikamu zvaro zvepurasitiki zvakaumbwa zvinonyanya kushandiswa kune goko remagetsi switch uye zvinodiwa zvezuva nezuva.
3-Kutamisa mold
Transfer mold inonziwo extrusion mold. Iyo yekuumba maitiro eiyi mold inoratidzwa nekuwedzera epurasitiki zvinhu mu preheated kuzadza kamuri, uyezve kushandisa kumanikidza kune epurasitiki zvinhu mukamuri yekuzadza neiyo yekumanikidza koramu, ipurasitiki inonyungudika pasi pekushisa kwakanyanya uye kumanikidzwa uye inopinda mugomba kuburikidza nekudurura. system ye mold, uyezve kemikari cross-linking inoitika uye zvishoma nezvishoma inoporesa. Iyo yekuchinjisa kuumba maitiro inonyanya kushandiswa kune thermosetting mapurasitiki uye inogona kuumba zvikamu zvepurasitiki zvine maumbirwo akaomarara.
4 – Extrusion Die
Extrusion die inonziwo extrusion head. Iyi inofa inogona kuramba ichibudisa mapurasitiki ane akafanana-sectional chimiro, zvakadai semapaipi epurasitiki, tsvimbo, mashizha, nezvimwewo. Iyo extruder inopisa uye inomanikidzwa nemudziyo wakafanana nemuchina wejekiseni. Plastiki iri munzvimbo yakanyungudutswa inopfuura nemumusoro kuti iite kuyerera kunoramba kuripo kwezvikamu zvepurasitiki zvakaumbwa, uye kugona kwekugadzira kunonyanya kukwirira.
Pamusoro pemhando dzakanyorwa pamusoro pemhando dzemapurasitiki, kune zvakare vacuum mold mold, compressed air molds, blow molding molds, yakaderera furo epurasitiki mold, nezvimwe.
