ʻO ka mold plastik kahi pōkole no ka mold hui ʻia i hoʻohana ʻia no ka hoʻoheheʻe ʻana, extrusion molding, injection, blow molding and low foam molding.Hiki i nā hoʻololi i hoʻohui ʻia o ka mold convex a me ka concave molds a me ka ʻōnaehana hoʻoheheʻe kōkua hiki ke hana i nā ʻāpana plastic o nā ʻano like ʻole a me nā nui like ʻole.ʻO nā ʻōpala palaki ka makuahine o ka ʻoihana, a ʻo nā huahana hou i hoʻokuʻu ʻia i kēia manawa e pili ana i nā plastics.

Loaʻa ka nui o ka mold wahine me ka lua ʻokoʻa i haku ʻia me kahi substrate i hui pū ʻia, kahi ʻāpana wahine a me kahi papa kāleka i hui pū ʻia, a me kahi ʻāpana convex i hui ʻia, kahi ʻāpana convex, kahi papa kāleka hui pū, a ʻāpana ʻoki ʻoki a me kahi kuʻi me kahi kumu hoʻololi i haku ʻia me nā ʻaoʻao i ʻoki ʻia.
I mea e hoʻomaikaʻi ai i ka hana o nā plastics, pono e hoʻohui ʻia nā mea kōkua like ʻole, e like me nā fillers, plasticizers, lubricants, stabilizers, colorants, etc., i ka polymer e lilo i plastics me ka hana maikaʻi.

1. ʻO ka resin synthetic ka mea koʻikoʻi o nā plastics, a ʻo kāna ʻike i loko o nā plastics he 40% a 100%.No ka mea nui ka ʻike, a ʻo ke ʻano o ka resin e hoʻoholo pinepine i ke ʻano o ka plastic, manaʻo pinepine ka poʻe i ka resin ma ke ʻano he synonym no ka plastic.No ka laʻana, huikau ka polyvinyl chloride resin me ka polyvinyl chloride plastics, a me ka phenolic resins me ka phenolic plastics.ʻO ka ʻoiaʻiʻo, ʻelua mau manaʻo like ʻole ka resin a me ka plastic.ʻO Resin kahi polymer makaʻole i hoʻohana ʻia ʻaʻole i hoʻohana wale ʻia no ka hana ʻana i nā plastics, akā he mea maka no ka uhi, adhesives, a me nā fiber synthetic.Ma waho aʻe o kahi ʻāpana liʻiliʻi loa o nā plastics i loaʻa ka 100% resin, ʻo ka hapa nui o nā plastics e koi i nā mea ʻē aʻe i hoʻohui ʻia i ka resin mea nui.

2. Kapaʻiaʻo Filler Filler he mea hoʻopihapiha, hiki ke hoʻonui i ka ikaika a me ka pale wela o nā plastic a hoʻemi i nā kumukūʻai.No ka laʻana, hiki i ka hoʻohui ʻana o ka pauka lāʻau i ka resin phenolic ke hoʻemi nui i ke kumukūʻai, e hana ana i ka plastic phenolic kekahi o nā plastics cheap loa, ʻoiai e hoʻomaikaʻi nui ana i ka ikaika mechanical.Hiki ke hoʻokaʻawale ʻia nā mea hoʻopihapiha i ʻelua mau ʻano: nā mea hoʻopihapiha kūlohelohe a me nā mea hoʻopiha inorganic, ʻo ka mea mua e like me ka palaoa lāʻau, nā ʻōpala, ka pepa a me nā ʻāpana lole like ʻole, a me nā mea hope e like me ke aniani fiber, diatomaceous earth, asbestos, a me ka ʻeleʻele kalapona.

3. Hiki i nā Plasticizers ke hoʻonui i ka plasticity a me ka maʻalahi o nā plastics, e hoʻemi i ka brittleness, a e maʻalahi i ka hana a me ke ʻano o nā plastic.ʻO ka plasticizer ka mea maʻamau i nā mea hoʻoheheʻe ʻia e hui pū me ka resin, ʻaʻohe mea ʻawaʻawa, ʻala ʻole, a kūpaʻa i ka māmā a me ka wela.ʻO ka mea maʻamau i hoʻohana ʻia he phthalate esters.No ka laʻana, i ka hana ʻana i nā plastics polyvinyl chloride, inā hoʻohui ʻia nā plasticizer hou aku, hiki ke loaʻa i nā plastic polyvinyl chloride palupalu;inā ʻaʻole i hoʻohui ʻia nā plasticizers (nui <10%), hiki ke loaʻa i nā plastik polyvinyl chloride paʻa.

4. Stabilizer No ka pale ʻana i ka resin synthetic mai ka decomposed a hōʻino ʻia e ka māmā a me ka wela i ka wā o ka hana ʻana a me ka hoʻohana ʻana, a no ka hoʻonui ʻana i ke ola lawelawe, pono e hoʻohui ʻia kahi stabilizer i ka plastic.ʻO ka mea maʻamau ka stearate a me ka epoxy resin.

5. Nā waihoʻoluʻu Hiki i nā kala kala ke hana i nā plastics i nā waihoʻoluʻu nani a nani.Hoʻohana maʻamau i nā mea waihoʻoluʻu a me nā puaʻa inorganic ma ke ʻano he kala.

6. Lubricant ʻO ka hana o ka lubricant ka pale ʻana i ka plastic mai ka pipili ʻana i ka mold metala i ka wā e hoʻoheheʻe ʻia, a i ka manawa like e hoʻomaʻamaʻa a nani hoʻi ka ʻili o ka plastic.ʻO nā lubricants maʻamau ka stearic acid a me kāna mau paʻakai calcium a me ka magnesium.Ma waho aʻe o nā mea hoʻohui i luna, hiki ke hoʻohui ʻia nā mea pale ahi, nā mea hoʻoulu, nā mea antistatic, etc.
