Nhazi RTM:
① Ịtinye ákwà eriri: a na-etinye ákwà eriri quartz a kwadebere n'ime oghere ebu n'otu oge;
② Ntụtụ Resin: A na-agwakọta resin na ihe na-akpali akpali n'ime igwekota static dị n'ihu egbe ọgwụ ahụ ma gbanye ya n'ime oghere ebu nke ejiri ákwà eriri kpuchie.
③ Ịgwọ Resin: a na-ekpo ọkụ oghere ebu iji mee ka ọgwụgwọ resin ahụ dị ngwa ngwa;
(iv) Mwepụ ngwaahịa: Mgbe e gwọrọ ma kpụọ resin ahụ, a na-emepe ebu ahụ iji nweta ihe mejupụtara ya ikpeazụ.
Mgbe usoro RTM (Resin Transfer Molding) gasịrị, a na-ahazi ákwà eriri quartz ma tinye ya na shei ígwè ahụ, a na-enwetakwa ngwaahịa ahụ mgbe setịpụchara ya mgbe anwalechara arụmọrụ ya, nke bụ ngwaahịa emechara.
