PTFE, yomwe imadziwika kuti Teflon, imagwiritsidwa ntchito pazifukwa zosiyanasiyana ndipo imodzi mwazo ndi zokutira pamwamba pazigawo.Chovala chodziwika bwino cha zokutira zotere ndi chophika chopanda ndodo pomwe kumaliza kwapamtunda kumagwira ntchito yofunika.PTFE itha kugwiritsidwanso ntchito pomaliza gawo lapamwamba.
PTFE ili ndi zinthu zambiri zomwe zimafunikira kuchokera kumadera owopsa.Ndi imodzi mwama insulators odalirika kwambiri m'mafakitale omwe kutchinjiriza ndikofunikira pachitetezo cha zida.PTFE ilinso ndi zinthu zopanda ndodo, komanso zosagwirizana zomwe zimafunikira mbali zina kuti zichepetse kuwonongeka.
PTFE zokutira ntchito ndi kaya yachibadwa kupopera mbewu mankhwalawa kapena electrostatic kupopera mbewu mankhwalawa.PTFE mu mawonekedwe a ufa ntchito mwachizolowezi mawonekedwe ndi kupopera mfuti bwinobwino.Mu electrostatic kupopera mbewu mankhwalawa wapadera mfuti ntchito zoipa mlandu particles PTFE ndi kupopera iwo pa zitsulo mbali amene pansi.Pazigawo zopanda zitsulo, pamwamba pangafunike kukonzekera kowonjezera.Gawolo limaphikidwa mu uvuni mutatha kugwiritsa ntchito PTFE kuti ziume ndi kuchiritsa pamwamba.
Prolean imapereka zotsatirazi pakuyala kwa PTFE:
| Kufotokozera | Tsatanetsatane |
| Gawo la Zinthu | Zitsulo ndi pulasitiki |
| Kukonzekera Pamwamba | Kutengera kutha kwa zinthu zomwe zili pamtunda, kuphulika kwa mikanda kapena kukonzedwa ndi mankhwala |
| Pamwamba Pamwamba | Yosalala kwambiri, kumaliza kwa matte ndi makulidwe ofanana.Zizindikiro siziwoneka ngati mikanda yaphulika |
| Kulekerera | Standard dimensional tolerances |
| Makulidwe | 10μm - 100μm (394μin - 3937μin) |
| Mtundu | Chakuda / Choyera |
| Gawo Masking | Kupaka kumapezeka malinga ndi kufunikira.Onetsani madera obisala pamapangidwe |
| Cosmetic kumaliza | Kumaliza zodzikongoletsera palibe |
