M'mawu osavuta, prototype ndi template yogwira ntchito yowunikira maonekedwe kapena kulingalira kwa kapangidwe kake popanga chitsanzo chimodzi kapena zingapo molingana ndi zojambula popanda kutsegula nkhungu.
1-CNC prototype kupanga
Makina a CNC ndi omwe amagwiritsidwa ntchito kwambiri, ndipo amatha kukonza zitsanzo zamalonda mwatsatanetsatane kwambiri.CNC chitsanzoali ndi ubwino wa kulimba kwabwino, kupanikizika kwakukulu komanso mtengo wotsika. Zipangizo zamtundu wa CNC zitha kusankhidwa mosiyanasiyana. Zida zazikulu zogwiritsira ntchito ndi ABS, PC, PMMA, PP, aluminiyamu, mkuwa, etc. Bakelite ndi aluminium alloy amagwiritsidwa ntchito popanga zida ndi zinthu zina.
2-Re-mold (kulowetsedwa kwa vacuum)
Kukonzanso ndikugwiritsira ntchito template yoyambirira kupanga nkhungu ya silikoni m'malo opanda vacuum, ndikutsanulira ndi zinthu za PU mu vacuum state, kuti apange chithunzi chomwe chili chofanana ndi choyambirira, chimakhala ndi kukana kutentha komanso kutentha kwambiri. mphamvu yabwino ndi kuuma kuposa template yoyambirira . Kukonzanso kwa vacuum kumathanso kusintha zinthu, monga kusintha zinthu za ABS kukhala zinthu zomwe zili ndi zofunikira zapadera.
Kumanganso vacuumZingathe kuchepetsa mtengo, Ngati ma seti angapo kapena ma seti angapo apangidwe, njira iyi ndiyabwino, ndipo mtengo wake ndi wotsika kuposa wa CNC.
3-3D yosindikiza yosindikiza
Kusindikiza kwa 3D ndi mtundu waukadaulo wachangu wa prototyping, womwe ndiukadaulo womwe umagwiritsa ntchito ufa, pulasitiki yofananira kapena zida zamadzimadzi zamadzimadzi kuti apange zinthu posindikiza ndi wosanjikiza.
Poyerekeza ndi pamwamba njira ziwiri, waukulu ubwino wa3D yosindikiza prototypendi:
1) Kuthamanga kwa zitsanzo za zitsanzo ndikofulumira
Nthawi zambiri, liwiro la ntchito SLA ndondomeko kusindikiza prototypes ndi 3 nthawi CNC kupanga prototypes, kotero kusindikiza 3D ndiye kusankha choyamba kwa tizigawo tating'ono ndi magulu ang'onoang'ono prototypes.
2) Njira yonse ya chosindikizira cha 3D imasinthidwa zokha, mawonekedwe ake amakhala olondola kwambiri, zolakwika zachitsanzo ndizochepa, ndipo zolakwika zochepa zimatha kuwongoleredwa mkati mwa ± 0.05mm
3) Pali zida zambiri zomwe mungasankhe pazithunzi zosindikizira za 3D, zomwe zimatha kusindikiza zida zopitilira 30, kuphatikiza zitsulo zosapanga dzimbiri ndi zitsulo zotayidwa.
