| Lintho tse bonahalang | Thepa | Tšebeliso e Tloaelehileng |
| Rabara ea Silicone | E thibela mocheso | Lisebelisoa tsa bongaka, litiiso |
| Thermoplastic Elastomers (TPE) | E tenyetseha, e tšoarellang | Li-grips tse bonolo |
Lintlha tsa Bohlokoa Khethong ea Lintho
1.Mechanical Properties: Nahana ka matla le ho tenyetseha.
2.Khanyetso ea Tikoloho: Lekola ho pepesehela lik'hemik'hale le mocheso.
3.Aesthetic Litlhokahalo: Khetha ho latela litlhoko tsa 'mala le qetello.
4.Tlaelo ya Taolo: Netefatsa polokeho le maemo a indasteri.
5.Litšenyehelo tsa Litšenyehelo: Leka-lekanya tšebetso le litšenyehelo.
| Ntlha | Ho nahanela |
| Thepa ea Mechini | Matla, ho tenyetseha |
| Khanyetso ea Tikoloho | Ho pepesehela lik'hemik'hale, mocheso |
| Litlhoko tsa Aesthetic | Mmala, qetellong |
| Tumellano ea Taolo | Tšireletseho, litekanyetso tsa indasteri |
| Litšenyehelo | Ts'ebetso khahlano le litšenyehelo |
Mehato ea ho Khetha Boitsebiso bo Nepahetseng
1.Hlalosa Litlhoko tsa Sehlahisoa: Hlalosa litlhoko tsa mochini le tsa tikoloho.
2.Consult Material Data Sheets: Bapisa thepa le tshebetso.
3.Prototype le Test: Lekola lisebelisoa maemong a sebele a lefatše.
4.Hlahloba Bokhoni ba Tlhahiso: Nahana ka bokhoni ba ho sebetsa le bofokoli.
5.Batla Keletso ea Setsebi: Buisana le litsebi tsa ho bōpa lintho tse bonahalang le ente.
Mathata a Tloaelehileng le Litharollo
1.Ho leka-lekanya Ts'ebetso le Litšenyehelo: Etsa tlhahlobo ea litšenyehelo tsa melemo.
2.Boteng ba Lintho: Theha likamano le barekisi ba bangata.
3.Moqapi oa Litšitiso: Ntlafatsa moralo bakeng sa manufacturability.
4.Kameho ea Tikoloho: Lekola lisebelisoa tse bolokang tikoloho joalo ka bioplastics.
Mekhoa ea Bokamoso ho Khetho ea Lintho
1.Lisebelisoa tse tsitsitseng: Nts'etsopele ea lipolasetiki tse ka senyehang le tse ka sebelisoang hape ho fokotsa tšusumetso ea tikoloho.
2.Mekhabiso e tsoetseng pele: Lintho tse ncha tse entsoeng ka metsoako, ho kopanya polasetiki le likhoele kapa li-nanoparticles, ho ntlafatsa thepa e kang matla le botsitso ba mocheso.
3.Lisebelisoa tse Bohlale: Lisebelisoa tse hlahang tse arabelang liphetohong tsa tikoloho li fana ka thepa e kang ho ipholisa le mohopolo oa sebopeho.
4.Digital Tools le AI: Lisebelisoa tsa dijithale le AI li ntse li sebelisoa haholo khethong ea thepa, e lumellang papiso e nepahetseng le ntlafatso, e fokotsa liteko le liphoso.
Ho khetha thepa e nepahetseng bakeng sa lihlahisoa tsa polasetiki tse tloaelehileng ho bohlokoa bakeng sa ho netefatsa boleng ba tsona le ho tšoarella. Ka ho utloisisa lisebelisoa tse fapaneng ka botlalo le ho hlahloba litlhoko tsa sehlahisoa sa hau ka hloko, u ka etsa liqeto tse nang le tsebo tse lekanyang ts'ebetso le litšenyehelo ka nepo. Ho lula u tseba ka lisebelisoa tse ncha le tsoelo-pele ea theknoloji ho tla thusa ho boloka moeli oa tlholisano 'marakeng.
