Katswiri wopanga makina opangira kutentha.
Thermoforming ndi jekeseni ndi njira ziwiri zodziwika bwino zopangira zida zapulasitiki, ndipo zimapereka maubwino apadera kutengera ntchito yake. Nawa mafotokozedwe achidule pakati pa njira ziwirizi.
Zida
Mu gawo la zida za thermoforming mawonekedwe amodzi a 3D amapangidwa kuchokera ku aluminiyamu, matabwa, polyurethane kapena chosindikizira cha 3D.
Popanga jekeseni, nkhungu ya 3D ya mbali ziwiri imapangidwa kuchokera ku aluminiyamu, chitsulo, kapena beryllium-copper alloy. Pali mwayi pa nthawi ndi mtengo ndi thermoforming popeza zitsanzo prototype akhoza kupangidwa kuchokera CNC kudula matabwa tooling.
Zipangizo
Thermoforming makina angagwiritse ntchito zipangizo zosiyanasiyana kuti apange mapepala athyathyathya omwe amapangidwa kukhala chinthu. Pali zosankha za kumaliza kosiyana, mtundu, ndi makulidwe a chinthucho.
Zopangidwa ndi jekeseni zimagwiritsa ntchito mapepala a thermoplastic, omwe amapezeka muzinthu zosiyanasiyana komanso mitundu yosiyanasiyana.
Kupanga
Muzida za thermoforming, pepala lathyathyathya la pulasitiki limatenthedwa kuti lizitha kutentha, kenako limapangidwa kukhala mawonekedwe a chidacho pogwiritsa ntchito kuyamwa kuchokera pa vacuum kapena kuyamwa ndi kukakamiza.
Popanga jekeseni, ma pellets apulasitiki amatenthedwa kuti akhale amadzimadzi ndikulowetsedwa mu nkhungu.
Nthawi
Ndi kuphatikiza kwa zida ndi kupanga, zimatha kupereka muyeso wolondola pa nthawi yomwe zimatengera kupanga zinthu zanu. Mu thermoforming, nthawi yapakati yopangira zida ndi masabata 0-8. Kutsatira zida, kupanga nthawi zambiri kumachitika mkati mwa masabata 1-2 chida chikavomerezedwa.
Pogwiritsa ntchito jakisoni, kugwiritsa ntchito zida kumatenga masabata 12-16 ndipo kumatha mpaka masabata 4-5 kuchokera pamene kupanga kuyambika.
Mtengo
Mtengo wa tooling mu thermoforming ndi wotsika mtengo kwambiri kuposa mtengo wa jekeseni akamaumba. Komabe, mtengo wopangira chidutswa chilichonse pakuumba jekeseni ukhoza kukhala wotsika mtengo kuposa thermoforming. Nthawi zambiri, kuumba jekeseni wa pulasitiki kumagwiritsidwa ntchito popanga zazikulu, zothamanga kwambiri ndipo thermoforming imagwiritsidwa ntchito popanga zing'onozing'ono zopanga komanso zoyendetsa zazikulu.
Pomwe kupita patsogolo kwaukadaulo wopanga kukupitilirabe kusinthika, malo omwe zosowa za chinthu ndi kuthekera kwapulasitiki thermoforming ndipo kuphatikizika kwa jekeseni kukuwonjezeka. Kusankha njira yoyenera pazochitikazi kumafuna kuunika mozama kwa mawonekedwe, mapindu, ndi ndalama zomwe zimagwirizanitsidwa ndi ndondomeko iliyonse.
Katswiri wopanga makina opangira kutentha.
