Plastic mold ipfupiso yeakasanganiswa mold inoshandiswa kumanikidza kuumba, extrusion molding, jekiseni, kuvhuvhuta uye kuderera kwefuro kuumba.Iyo yakarongedzerwa shanduko ye mold convex uye concave mold uye yekubatsira molding system inogona kugadzirisa akateedzana ezvikamu zvepurasitiki zvemaumbirwo akasiyana uye hukuru hwakasiyana.Plastic molds ndivo mai veindasitiri, uye kuburitswa kwechigadzirwa chitsva ikozvino kunosanganisira mapurasitiki.

Iyo inonyanya zvinosanganisira mold yechikadzi ine mhango inosiyana inoumbwa neyechikadzi mold yakasanganiswa substrate, yevakadzi mold chikamu uye yechikadzi mold yakasanganiswa kadhi bhodhi, uye convex mold yakasanganiswa substrate, convex mold chikamu, chirume mold yakasanganiswa kadhi bhodhi, a mhango yekucheka chikamu uye A punch ine tsinga inoshanduka inoumbwa neside-cut composite plates.
Kuti uvandudze mashandiro emapurasitiki, zvinhu zvakasiyana-siyana zvekubatsira, zvakaita semafirita, mapurasitiki, mafuta ekuzora, zvigadzikiso, marangi, nezvimwewo, zvinofanirwa kuwedzerwa kumapolymer kuti ave mapurasitiki ane mashandiro akanaka.

1. Synthetic resin ndiyo inonyanya kukosha yepurasitiki, uye zvinyorwa zvayo mumapurasitiki zvinowanzoita 40% kusvika ku100%.Nekuti zviri mukati zvakakura, uye chimiro cheresin chinowanzo tarisa chimiro chepurasitiki, vanhu vanowanzo tora resin serinofanana nepurasitiki.Semuenzaniso, vhiringa polyvinyl chloride resin ne polyvinyl chloride mapurasitiki, uye phenolic resins ane phenolic plastiki.Muchokwadi, resin nepurasitiki ipfungwa mbiri dzakasiyana.Resin ipolymer isina kugadziridzwa isingashandiswe kugadzira mapurasitiki chete, asiwo chinhu mbishi chekuputira, chekunamira, uye mafivha ekugadzira.Pamusoro pechikamu chidiki chemapurasitiki ane 100% resin, mapurasitiki mazhinji anoda zvimwe zvinhu mukuwedzera kune chikuru chikamu resin.

2. Filler Filler inonziwo filler, iyo inogona kuvandudza simba uye kupisa kupisa kwemapurasitiki uye kuderedza mari.Semuenzaniso, kuwedzerwa kwehuni hupfu kune phenolic resin kunogona kuderedza zvakanyanya mutengo, zvichiita kuti phenolic plastiki ive imwe yemapurasitiki akachipa, uye ichivandudza zvakanyanya simba remagetsi.Mafirita anogona kupatsanurwa mumhando mbiri: organic fillers uye inorganic fillers, yekare senge hupfu hwehuni, mamvemve, bepa uye akasiyana machira eshinda, uye ekupedzisira senge girazi fiber, diatomaceous pasi, asbestos, uye kabhoni dema.

3. Plasticizers Plasticizers inogona kuwedzera mapurasitiki uye kushanduka kwepurasitiki, kuderedza brittleness, uye kuita kuti mapurasitiki ave nyore kugadzirisa uye kuumbwa.Plasticizers anowanzo kuvirisa organic komisheni iyo inosanganiswa neresin, isina-chepfu, isina kunhuhwirira, uye yakagadzikana kuchiedza nekupisa.Inonyanya kushandiswa ndeye phthalate esters.Semuenzaniso, mukugadzirwa kwepolyvinyl chloride plastiki, kana mamwe mapurasitiki akawedzerwa, mapurasitiki akapfava epolyvinyl chloride anogona kuwanikwa;kana pasina kana mashoma epurasitiki akawedzerwa (huwandu <10%), yakaoma polyvinyl chloride mapurasitiki anogona kuwanikwa.

4. Stabilizer Kuti udzivise resin yakagadzirwa kubva pakuora uye kukuvadzwa nechiedza uye kupisa panguva yekugadzira uye kushandiswa, uye kuwedzera hupenyu hwebasa, stabilizer inofanira kuwedzerwa kupurasitiki.Inonyanya kushandiswa ndeye stearate uye epoxy resin.

5. Colorants Colorants inogona kuita mapurasitiki ane mavara akasiyana-siyana akajeka uye akanaka.Inowanzo shandiswa organic dhayi uye inorganic pigments semavara.

6. Lubricant Basa rekuzora nderokudzivirira purasitiki kuti isanamatira kune simbi mold panguva yekugadzira, uye panguva imwechete inoita kuti pamusoro pepurasitiki iite zvakanaka uye yakanaka.Mafuta anowanzo shandiswa anosanganisira stearic acid uye ayo calcium uye magnesium munyu.Pamusoro pezvinowedzera zviri pamusoro, zvinodzosa moto, zvinopupuma, antistatic agents, nezvimwewo zvinogonawo kuwedzerwa kupurasitiki.
