⑴ nrụgide ịkpụzi: ịkpụzi ma ọ bụ ịpị ịkpụzi.Ọ bụ tumadi ji maka ịkpụzi thermosetting plastics dị ka phenolic resin, urea-formaldehyde resin na unsaturated polyester resin.

⑵ extrusion: extrusion ịkpụzi, bụ ojiji nke extrusion igwe (extruder) ga-kpụ ọkụ n'ọnụ resin na-aga n'ihu site ebu, extrusion chọrọ udi nke ngwaahịa method.Extrusion na-mgbe ụfọdụ na-eji na thermosetting plastic ịkpụzi, na ike ga-eji na ịkpụzi nke ụfụfụ plastics.The uru nke extrusion bụ na ọ nwere ike extrude dị iche iche shapes nke ngwaahịa, elu mmepụta arụmọrụ, akpaka na-aga n'ihu mmepụta;The e mwepu bụ na thermosetting plastic eriri enweghị ike ọtụtụ-eji na usoro a nke nhazi, ngwaahịa size mfe na-emepụta deviation. .

⑶ Injection molding: injection molding.Injection molding bụ ojiji nke injection na-akpụzi igwe (ma ọ bụ igwe injection) na-agbaze ụdọ thermoplastic n'okpuru nrụgide dị elu n'ime ebu mgbe ọ dị jụụ, siri ike iji nweta usoro ngwaahịa. na ụfụfụ plastic eriri ịkpụzi.Injection ịkpụzi nwere uru nke ngwa ngwa mmepụta ngwa ngwa, elu arụmọrụ, akpaaka nhazi, na nwere ike ịkpụzi akụkụ mgbagwoju anya, karịsịa adabara maka uka mmepụta.The mwepu bụ na-eri nke ngwá na ebu dị elu, na injections. igwe na-akpụzi siri ike ihicha.

⑷ Ịkpụzi ịkpụzi: ịkpụzi oghere oghere ma ọ bụ ịkpụzi oghere. Ịkpụ akpụ bụ usoro nke ịfụ ngwaahịa oghere site na nrụgide nke ikuku abịakọrọ iji mee ka resin billet na-ekpo ọkụ mechie na ebu.Ịkpụzi ihe ọkụkụ na-agụnye ụzọ abụọ nke ihe nkiri na-akpụzi ihe na-akpụzi ngwaahịa oghere. Site na usoro ịkpụzi ihe nwere ike ịmepụta ngwaahịa fim, karama dị iche iche, gbọmgbọm, ite na ihe ụmụaka ji egwuri egwu.

⑸ Calendering: Ọ bụ usoro ịkpụzi nke resin na ihe mgbakwunye dị iche iche na-esizi (igwakorita, nzacha, wdg) n'ime fim ma ọ bụ mpempe akwụkwọ site na oghere dị n'etiti abụọ ma ọ bụ karịa na-emegide calendering rollers nke calender, nke na-apụzi na roller na kalenda, na mgbe ahụ ekara site cooling.Calendering bụ tumadi ji polyvinyl chloride resin ịkpụzi usoro, nwere ike na-emepụta fim, mpempe akwụkwọ, efere, wuru akpụkpọ anụ, n'ala taịl nile na ndị ọzọ na ngwaahịa.
