Rubber Molding Ente Molding bakeng sa Lihlahisoa tsa Rubber
Lihlahisoa tse entsoeng ka Ente e Tloaelehileng
Compression Molding
Ha ho etsoa compression, motsoako oa rabara o kenngoa ka har'a mokoti oa hlobo, 'me khatello e sebelisoa ho hatella thepa hore e be sebopeho se lakatsehang. Joale mocheso o sebelisoa ho phekola rabara. Mokhoa ona o sebelisoa hangata ho etsa lihlahisoa tse kang li-gaskets, litiiso le likarolo tsa koloi.
Ho Bopa ka Ente
Ho etsa ente ho kenyelletsa ho kenya rabara e qhibilihisitsoeng ka har'a hlobo e tlas'a khatello e matla. Ts'ebetso ena e nepahetse bakeng sa ho etsa likarolo tse rarahaneng le tse nepahetseng, ho kenyeletsoa likarolo tsa koloi le thepa ea bareki. Overmolding le ho kenya ho bōptjoa ke mefuta e fapaneng ea ts'ebetso ena, e kenyelletsang ho kopanngoa ha likarolo tsa tšepe tse phethiloeng ka har'a mokoti oa hlobo pele o kenya rabara.
Ho fetisoa Moulding
Ho kopanya likarolo tsa ho hatella le ho etsa ente, ho bopa ho fetisa ho sebelisa tekanyo e lekantsoeng ea rabara ka kamoreng e futhumetseng. Plunger e qobella thepa hore e be mokoti oa hlobo, e etsa hore e tšoanelehe bakeng sa ho hlahisa likhokahanyo tsa motlakase, li-grommets le likarolo tse nyane tse nepahetseng.
Extrusion
Extrusion e sebelisoa ho theha bolelele bo tsoelang pele ba rabara e nang le libopeho tse fapaneng tse fapaneng, joalo ka li-hoses, li-tubing le li-profiles. Rabara e qobelloa ka lefu ho finyella tlhophiso e lakatsehang.
Ho phekola (Vulcanization)
Ho phekola, kapa vulcanization, ho kenyelletsa ho hokahanya liketane tsa polymer ea rabara ho matlafatsa matla, elasticity le ho hanyetsa mocheso. Sena se finyelloa ka ho sebelisa mocheso le khatello ho sehlahisoa sa rabara se bōpiloeng, ka mekhoa e tloaelehileng e kenyeletsang mouoane, moea o chesang, le phekolo ea microwave.
Rubber ho Metal Bonding
Ts'ebetso e khethehileng, ho kopanya rabara ho tšepe ho etsa lihlahisoa tse kopanyang ho feto-fetoha ha rabara le matla a tšepe. Karolo ea rabara e entsoe esale pele kapa e bōptjoa, e behoa holim'a tšepe ka sekhomaretsi, ebe e kenngoa mocheso le khatello bakeng sa vulcanization kapa ho phekola. Ts'ebetso ena e tlama rabara le tšepe ka lik'hemik'hale, e etsa hore ho be le khokahanyo e tiileng le e tšoarellang ea bohlokoa bakeng sa lits'ebetso tse hlokang ho thothomela le ho ts'ehetsa sebopeho.
Ho kopanya
Ho kopanya ho kenyelletsa ho kopanya lisebelisoa tsa rabara tse tala le li-additives tse fapaneng ho etsa motsoako oa rabara o nang le thepa e khethehileng. Li-additives li ka kenyelletsa lisebelisoa tsa ho folisa, li-accelerator, li-antioxidants, li-filler, li-plasticizers le li-colorants. Ho kopanya hona hangata ho etsoa ka leloala la li-roll tse peli kapa motsoako o ka hare ho etsa bonnete ba kabo e tšoanang ea li-additives.
Milling
Ka mor'a ho kopanya, motsoako oa rabara o kena lits'ebetsong tsa ho sila kapa ho kopanya ho tsoela pele ho homogenize le ho bōpa thepa. Mohato ona o tlosa li-bubble tsa moea 'me o tiisa ho tšoana ho motsoako.
Kamora ho sebetsa
Ka mor'a ho phekoloa, sehlahisoa sa rabara se ka 'na sa e-ba le mekhoa e meng, ho kenyelletsa le ho kuta, ho senya (ho tlosa lintho tse feteletseng), le ho phekola ka holim'a metsi (joaloka ho roala kapa ho bentša) ho finyella litlhoko tse khethehileng.

Rubber Molding Materials
Mofuta o mong le o mong oa rabara o na le thepa e ikhethang, e etsang hore e tšoanelehe bakeng sa lits'ebetso tse ikhethileng. Khetho ea thepa ea rabara e ipapisitse le lintlha tse kang ts'ebeliso e reriloeng, maemo a tikoloho, mocheso, ho pepesehela lik'hemik'hale, le litšobotsi tse lakatsehang tsa 'mele.
Mona ke mefuta e meng ea mantlha ea rabara:
Rabara ea Tlhaho (NR):
E tsoa ho lero la latex la sefate sa rabara (Hevea brasiliensis), rabara ea tlhaho e tsebahala ka ho phutholoha ho phahameng le ho tiea. E sebelisoa hangata lits'ebetsong tse kang lithaere, lieta le lihlahisoa tsa bareki, e na le khanyetso e fokolang mochesong le lik'hemik'hale.
Rabara ea maiketsetso:
E entsoe ka maiketsetso ka mekhoa ea lik'hemik'hale, li-rabara tsa maiketsetso li fana ka mefuta e mengata ea thepa. Mefuta e meng e tloaelehileng e kenyelletsa:
