Ụfụfụ oche n'ozuzu na-ezo aka na ụfụfụ polyurethane, nke a na-eji ihe abụọ mejupụtara gbakwunyere ihe mgbakwunye kwekọrọ na obere ihe ndị ọzọ, bụ nke a na-agbapụta site na ebu.A na-ekewa usoro mmepụta dum n'ime usoro atọ: ọkwa nkwadebe, ọkwa mmepụta na ọkwa nhazi post-processing.
1. Ogbo nkwadebe - nyocha na-abata + ịgwakọta
①Nyocha ihe na-abata:
Na-elele anya ma ọdịnaya mmiri na viscosity nke polyether na-emezu ihe achọrọ.Ihe a dị mkpa karịsịa n'oge oyi n'ebe ugwu.
A na-arụkwa mmepụta nnwale ụfụfụ efu maka ihe ndị na-abata, na-atụkarị aro iji nyochaa ma ha zutere ihe achọrọ ọkwa mmepụta.
②Ngwakọta:
A na-eme ngwakọta dị ka usoro a kwadoro, a na-ejikwa ngwa ngwa ngwa ngwa na-eji ugbu a.A na-ekewa sistemụ ụfụfụ oche FAW-Volkswagen ụzọ abụọ: ihe mejupụtara na ihe na-agwakọta onwe ya.

Ngwakọta onwe: gwakọta POLY, ya bụ, ihe mgbakwunye polyether + POP +, wee gwakọta POLY na ISO.
2. Ogbo mmepụta - mmepụta akaghị
N'ozuzu, a na-anakwere mmepụta loop, tumadi site na ọtụtụ usoro dị ka ịwụsa, ịmepụta, ịkwatu, na ihicha ebu, dị ka ndị a:
N'ime ha, ịwụsa bụ igodo, nke a na-emecha site na onye na-agbapụta mmiri.A na-eji usoro ịwụsa dị iche iche dị ka ọnọdụ dị iche iche nke ụfụfụ oche, ya bụ, a na-awụpụ ụfụfụ na mpaghara dị iche iche, na usoro usoro dị iche iche (nrụgide, okpomọkụ, usoro, njupụta ụfụfụ, ụzọ mgbapụ, ntinye nzaghachi).
3. Ogbo nhazi mgbe emechara - gụnyere mkpọpu ala, trimming, koodu, ịrụzi, ịgba silencer wax, ịka nká na usoro ndị ọzọ.
①Oghere - Ebumnuche nke imeghe bụ iji gbochie nrụrụ ngwaahịa na ịbawanye ngbanwe.Kewara n'ime ụdị mgbasa ozi agụụ na rola ụdị.

②Edge trimming-foam N'ihi usoro nke ikpochapu ebu, a ga-emepụta ụfọdụ ụfụfụ ụfụfụ na nsọtụ nke ụfụfụ ahụ, nke ga-emetụta ọdịdị ahụ mgbe ọ na-ekpuchi oche na mkpa iji aka wepụ ya.
③Ndokwa - ejiri chọpụta ụbọchị mmepụta na batch nke ụfụfụ.
④Ndozi - ụfụfụ ga-emepụta obere ntụpọ dị mma n'oge usoro mmepụta ma ọ bụ nkwụsịtụ.N'ozuzu, a na-eji gluu na-edozi ntụpọ.Agbanyeghị, FAW-Volkswagen kwuru na anaghị ekwe ka emezigharị elu A, yana enwere ụkpụrụ ịdị mma pụrụ iche iji gbochie ọrụ nrụzi..
⑤Fesa wax na-amịpụta ụda - ọrụ bụ igbochi esemokwu dị n'etiti ụfụfụ na oche oche iji mee mkpọtụ.
⑥Ịka nká - Mgbe a na-akpụzi ụfụfụ ahụ site na ọkpụkpụ ahụ, a na-emeghachighị ihe na-emepụta ụfụfụ n'ozuzu ya, a na-achọkwa micro-reactions.N'ozuzu, a na-akwụsịtụ ụfụfụ na ikuku na catenary maka awa 6-12 maka ọgwụgwọ.
