Matanho ekutanga eThermoforming
1. Kugadzirira Zvinhu
Nhanho yekutanga muiyo thermoforming process ndeyekusarudza nekugadzirira yakakodzera pepa repurasitiki zvinhu. Mashizha anowanzo shandiswa anosanganisira Polystyrene (PS), Polyethylene Terephthalate (PET), High Impact Polystyrene (HIPS), Polypropylene (PP), uye Polylactic Acid (PLA). Zvinhu zvakasiyana-siyana zvine zvivakwa zvakasiyana uye zvakakodzera kune akasiyana maapplication. Sarudzo yezvinyorwa ndiyo nheyo yekubudirira kwese kwemaitiro, saka kunyanya kutarisisa kunodiwa.
Tafura: Zvakajairwa Thermoforming Zvishandiso uye Zvivakwa Zvavo
| Material | Kudimburira | Properties | Common Applications |
| Polystyrene | PS | Rigid, nyore kugadzirisa | Midziyo inoraswa, mabhokisi ekurongedza |
| Polyethylene Terephthalate | PET | High transparency, impact resistance | Mabhodhoro ezvinwiwa, kurongedza chikafu |
| High Impact Polystyrene | HUP | Kuramba kwakasimba kwesimba, kusimba kwakanaka | Dzimba dzemagetsi, kurongedza chikafu chakaomeswa |
| Polypropylene | PP | Zvakanaka kupisa kupisa, kugadzikana kwemakemikari | Kurongedza chikafu, kurongedza kwemishonga |
| Polylactic Acid | PLA | Biodegradable, eco-hushamwari | Compostable midziyo, bio-packaging |
Munguva yegadziriro yezvinhu, iyo shizha repamusoro rinodawo kucheneswa kubvisa chero guruva kana tsvina inogona kukanganisa kuumba mhando. Kune mamwe maapplication anodiwa zvakanyanya, mashiti anogona zvakare kudiwa pre-kurapwa, sekushandisa anti-static agents kana kugadziridzwa kwepasi.
2. Kupisa
Kupisa ndiyo imwe yenhanho dzakanyanya kukosha muiyo thermoforming process, uko pepa repurasitiki rinopisa kusvika pakunyorovesa kwayo tembiricha, zvichiita kuti rive rakakwana. Midziyo yekudziisa inowanzo shandisa infrared kudziyisa kana kuramba kudziyisa kuti ive nechokwadi chekuti pepa rinodziya zvakaenzana.
Zvinhu zvakasiyana zvinoda kupisa tembiricha uye nguva dzakasiyana. Semuenzaniso, mapepa ePET anowanzoda kupiswa mukati metembiricha ye120-160 ° C, nepo maHIPS mapepa anowanzoda kudziyisa pakati pe80-120 ° C. Iyo yekudziya haingofanire kufunga nezvekunyorovesa kwechinhu asi zvakare inofanirwa kuve nechokwadi chekuti shiti hariparare kana kuderera panguva yekupisa. Naizvozvo, kunyatso kudzora tembiricha yemidziyo yekudziya inodiwa, uye kutonhora kana kugadzirisa kunogona kudikanwa kana zvichidikanwa.
Mukugadzirwa kwemaindasitiri, kufanana kwekudziya kwakakosha pakuumba mhando. Kana shiti racho risina kudziyisa zvakaenzana, rinogona kuguma nekupenya kwepamusoro, kuora mwoyo, kana kusiyana kwehukobvu muchigadzirwa chakapedzwa. Nyaya idzi hadzingokanganisa kutaridzika kwechigadzirwa chete asi dzinogona kukanganisawo ma mechanic properties uye kusimba kwayo. Nokudaro, kunyanya kukoshesa kunofanira kubhadharwa kune kufanana kwepepa panguva yekupisa.
3. Kuumba
Kugadzira inzira yekuendesa pepa repurasitiki rinodziya kuita mold uye kushandisa vacuum suction, kudzvanywa, kana simba remagetsi kuigadzira. Iyo yekugadzira maitiro inogona kukamurwa kuita vacuum kuumba, kumanikidza kuumba, uye mechanic kuumba, imwe neimwe iine yayo yakasarudzika mabhenefiti uye mashandisiro.
Mukugadzira vacuum, iyo shiti inonamirwa zvakanyanya kune mold pamusoro kuti igadzire iyo inodiwa chimiro. Iyi nzira inowanzo shandiswa kugadzira zvigadzirwa zvakatetepa-zvakakomberedzwa semidziyo inoraswa uye mabhokisi ekurongedza chikafu. Dzvinyiriro yekugadzira inotsikirira pepa muforoma, yakakodzera kugadzira yakakwirira-yakasimba uye yakaoma-yakaumbwa zvigadzirwa. Mechanical kuumba inoshandisa michina michina kuisa kumanikidza zvakananga, inonyanya kushandiswa kugadzira zvigadzirwa zvakakora-madziro.
Munguva yekuumba maitiro, ma paramita akadai sekumanikidza, nguva, uye tembiricha inoda kudzorwa. Kudzvinyirira kwakanyanya kunogona kuita kuti bepa riparare, nepo kusakwana kudzvanywa kunogona kukonzera kusakwana kwechigadzirwa chimiro. Kurebesa kuumba nguva kunogona kukonzera kuchembera kwezvinhu, nepo ipfupi nguva inogona kudzivirira kubereka kuzere kwezve chigadzirwa.
4. Kutonhodza
Kutonhodza inzira yekukasira kutonhodza chigadzirwa chepurasitiki chakaumbwa kusvika chakasimba. Iko kumhanya kwekutonhora kunobata zvakananga kugadzikana kwechigadzirwa uye kunaka kwepamusoro. Kutonhodza kunowanzoitwa uchishandisa mhepo kana mvura, zvichienderana nechimiro chechigadzirwa, zvinhu, uye kugadzirwa kwakanaka zvinodiwa.
5. Kucheka
Mushure mekutonhora kwapera, zvigadzirwa zvakaumbwa zvinoda kuchekwa kuti zvibvise zvikamu zvakawandisa, kuve nechokwadi kuchena uye kwakaringana mipendero. Zvigadzirwa zvakachekwa zvinoda kumwe kuongororwa kuti ive nechokwadi chekuti zvinosangana nehukuru hunodiwa uye maumbirwo.
6. Kuunganidza tsvina
Tsvina inogadzirwa panguva yekugadzira thermoforming, senge kucheka kumucheto uye zvigadzirwa zvisina kukwana, inowanzounganidzwa kuti idzokororwe. Izvi hazvingobatsiri kuderedza marara emarara asiwo zvinosangana nezvinodiwa zvezvakatipoteredza. Mushure mekuunganidzwa kwemarara, zvinhu izvi zvinogona kudzokororwa kuita mapepa matsva kuti aenderere mberi nekugadzirwa.
