Tlhahisong ea indasteri, lithipa tse chitja tsa carbide e se e le lisebelisoa tse ratoang bakeng sa ts'ebetso e mengata ea ho itšeha ka lebaka la ts'ebetso ea tsona e ntle ea ho sesa, ho thatafala le ho hanyetsa kutu. Leha ho le joalo, ha u tobane le litlhoko tsa ho itšeha tsa lisebelisoa tse fapaneng tse kang lipolasetiki, litšepe le lipampiri, ho khetha lisebelisoa tse nepahetseng tsa ho etsa lisebelisoa ho amana ka kotloloho le katleho ea ho itšeha, bophelo ba lisebelisoa le boleng ba sehlahisoa. Ka mor'a moo, re tla hlahloba ka botebo mekhoa ea saense ea ho khetha lisebelisoa tsa ho etsa li-carbide tse pota-potileng lithipa ha u seha lisebelisoa tse fapaneng ka mokhoa oa litafole le manane.
1. Khetho ea Lisebelisoa tsa ho Seha Lisebelisoa tsa Plastiki
Lisebelisoa tsa polasetiki li tla ka mefuta e mengata, 'me litlhoko tsa lisebelisoa tsa lisebelisoa li fapana haholo bakeng sa mefuta e fapaneng ea polasetiki. Likhetho tse khethehileng ke tse latelang:
.
| Mofuta oa polasetiki | Lisebelisoa tsa Moemeli | Material Characters | Recommended Tool Materials | Advantage Explanation |
| Plastiki e bonolo | Polyethylene (PE), Polypropylene (PP). | Boima bo tlase, ho bonolo ho khomarela lisebelisoa | Carbide e nang le cobalt (Co) content ea 10% -15%. | Lintho tse phahameng tsa cobalt li ntlafatsa ho tiea ha sesebelisoa, li fokotsa ho khomarela ka polasetiki, li netefatsa ho itšeha ka nepo, 'me li fokotsa ho roala. |
| Plastiki e thata | Polycarbonate (PC), Polyoxymethylene (POM). | Boima bo phahameng, khanyetso e matla ea ho apara | WC-Co carbide e halikiloeng hantle kapa ea boleng bo holimo | Sebopeho se entsoeng hantle se ntlafatsa ho thatafala le ho roala ho hanyetsa ha sesebelisoa, ho lelefatsa bophelo ba eona ba ts'ebeletso ka makhetlo a 2-3 |

2. Khetho ea Lisebelisoa tsa ho Seha Lisebelisoa tsa Metal
Ts'ebetso ea ho itšeha ka tšepe e na le litlhoko tse thata haholo bakeng sa ts'ebetso ea lithipa tse chitja tsa carbide. Ho ea ka litšoaneleho tse fapaneng tsa litšepe tse se nang ferrous le tšepe, lintlha tsa bohlokoa tsa ho khetha lisebelisoa tsa lisebelisoa ke tse latelang:
(1) Metals Non-Feron (Ho Nka Aluminium le Aluminium Alloys e le Mehlala)
- Litšobotsi tsa Lintho: Ho thata ho tlase, empa ho na le ductility e ntle, le likarolo tse hahiloeng li ka etsahala nakong ea ho itšeha
- Lisebelisoa tsa Lisebelisoa tse khothalelitsoeng: Lithipa tse chitja tsa Carbide tse nang le bokaholimo bo apesitsoeng ke TiAlN (Titanium Aluminium Nitride).
- Molemo oa Tlhaloso: Ho roala ho fokotsa khohlano pakeng tsa sesebelisoa le tšepe, ho fokotsa likarolo tse hahiloeng, 'me ho ntlafatsa ho hanyetsa le ho hanyetsa oxidation ea sesebelisoa.
(2) Litšepe tse Ferrous (Ho Nka Carbon Steel le Alloy Steel e le Mehlala).
- Litšobotsi tsa Lintho: Ho thata haholo, matla a phahameng, le mocheso o mongata le matla a ho itšeha li hlahisoa nakong ea ho itšeha
- Lisebelisoa tsa Lisebelisoa tse khothalelitsoeng: WC-TiC-Co series carbide e nang le karolo e phahameng ea tungsten carbide (WC) le titanium carbide (TiC).
- Molemo oa Tlhaloso: E ka boloka boima bo botle 'me ea apara ho hanyetsa mocheso o phahameng, ea boloka ka mokhoa o tsitsitseng bohale ba ho itšeha, le ho ntlafatsa katleho ea ho itšeha.
3. Khetho ea Lisebelisoa tsa ho Seha Lipampiri le Lisebelisoa tsa Fiber
Lisebelisoa tsa pampiri le li-fiber li batla li le bonolo, empa bothata ba ho kenngoa ha fiber ka sesebelisoa ho ka etsahala. Mekhoa ea ho khetha lisebelisoa tsa lisebelisoa ke tse latelang:
| Mofuta oa Material | Lisebelisoa tsa Moemeli | Mathata a Tloaelehileng | Recommended Tool Materials | Mekhoa ea Phekolo le Melemo |
| Lipampiri tse Tloaelehileng | Pampiri ea khatiso, pampiri ea ho ngola, joalo-joalo | - | Medium-hardness carbide | Ts'ebetso e ntle ea ho itšeha, e ka khaola fiber kapele, 'me e na le bophelo bo bolelele ba ts'ebeletso |
| Lisebelisoa tsa High-Fiber | Letlalo, lesela, lesela le sa lohiloeng | Li-fibers li bonolo ho kopanya sesebelisoa | Carbide e nang le kalafo ea seipone se holim'a metsi kapa ho itlotsa ka ho itlotsa | Phekolo ea seipone e fokotsa ho ba mahlahahlaha holim'a metsi, 'me ho itlotsa ka bohona ho fokotsa khohlano, ho qoba ho ts'oaroa ha fiber le ho seha hantle. |
4. Lintlha Tse Ling Bakeng sa ho Khetha Lisebelisoa tsa Tlhahiso ea Lisebelisoa
Ntle le lisebelisoa, lintlha tse latelang li boetse li hloka ho nahanoa ka botlalo ha u khetha lisebelisoa tsa ho etsa lisebelisoa:
- Ts'ebetso ea ho itšeha ea lisebelisoa: Lisebelisoa tsa ho itšeha ka lebelo le phahameng li hloka lisebelisoa ho ba le matla a holimo le ts'ebetso e matla ea ho leka-lekanya
- Li-Parameters tsa Ts'ebetso ea ho Seha: Lebelo la ho itšeha, sekhahla sa phepelo, joalo-joalo, se hloka ho tsamaisana le ts'ebetso ea lisebelisoa tsa lisebelisoa ho fihlela phello e ntle ka ho fetisisa ea ho itšeha.
- Litšenyehelo Factor: Boemong ba ho fihlela litlhoko tsa ho itšeha, etelletsa pele ho khetha lisebelisoa tsa lisebelisoa tse theko e phahameng haholo ho fokotsa litšenyehelo tsa tlhahiso.
Ha lithipa tse chitja tsa carbide li khaola lisebelisoa tse fapaneng, khetho ea lisebelisoa tsa ho etsa lisebelisoa ke mokhoa o felletseng oa ho etsa liqeto. Ke feela ka ho utloisisa ka botlalo litšoaneleho tsa thepa ea ho itšeha, ho kopanya lintlha tse kang lisebelisoa tsa ho itšeha, litekanyetso tsa ts'ebetso le litšenyehelo, ho ka khethoa lisebelisoa tsa lisebelisoa tse loketseng ka ho fetisisa ho etsa bonnete ba hore ts'ebetso ea ho itšeha e etsoa ka katleho le ka mokhoa o tsitsitseng, ho theha boleng bo boholo bakeng sa khoebo.
