Tare da fadi da aikace-aikace nasamfuran filastik, jama'a yana da mafi girma da kuma mafi girma da bukatun ga bayyanar ingancin filastik kayayyakin, don haka da surface polishing ingancin na filastik mold rami ya kamata kuma a inganta daidai da, musamman m m surface roughness na madubi surface da high-mai sheki high-haske surface. Abubuwan da ake buƙata sun fi girma, sabili da haka buƙatun don gogewa kuma sun fi girma.

A halin yanzu, hanyoyin goge goge da aka saba amfani da su sune kamar haka:
(1) Gyaran injina
Gyaran injina wata hanya ce ta gogewa wanda ake samun santsi mai santsi ta hanyar yankan da nakasar filastik na saman kayan don cire sashin da aka goge. Gabaɗaya, ana amfani da ɗigon dutse, ƙafafun ulu, takarda yashi, da sauransu. Yin amfani da kayan aikin taimako irin su turntables, ultra-lafiya nika da hanyoyin goge baki ana iya amfani da su ga waɗanda ke da buƙatun ingancin ƙasa. Ultra-daidaici nika da polishing ne na musamman abrasive kayan aiki, wanda aka guga man a saman na workpiece da za a machined a cikin nika da polishing ruwa dauke da abrasive, da kuma juya a babban gudun. Yin amfani da wannan fasaha, za a iya cimma raƙuman ruwa na Ra0.008μm, wanda shine mafi girma a cikin hanyoyi daban-daban na gogewa. Nau'in ruwan tabarau na gani sau da yawa suna amfani da wannan hanyar
(2) Ultrasonic polishing
A workpiece da aka sanya a cikin abrasive dakatar da kuma sanya shi a cikin ultrasonic filin tare, da kuma abrasive ne kasa da goge a kan surface na workpiece da oscillation na ultrasonic kalaman. Ƙarfin macroscopic na aiki na ultrasonic ƙananan ne, kuma ba zai haifar da nakasawa na kayan aiki ba, amma yana da wuya a yi da shigar da kayan aiki. Ana iya haɗa mashin ɗin ultrasonic tare da hanyoyin sinadarai ko na lantarki. Dangane da lalatawar bayani da electrolysis, ana amfani da vibration na ultrasonic don tayar da maganin, don haka samfuran da aka narkar da su a saman kayan aikin sun rabu, kuma lalata ko electrolyte kusa da farfajiyar sun kasance uniform; da cavitation sakamako na ultrasonic tãguwar ruwa a cikin ruwa kuma iya hana lalata tsari, wanda shi ne conducive to surface haske.

(3) Gyaran ruwa
Gyaran ruwa ya dogara da ruwa mai saurin gudu da kuma barbashi da ke ɗauke da shi don zazzage saman kayan aikin don cimma manufar gogewa. Hanyoyin da aka fi amfani dasu sune: abrasive jet machining, ruwa jet machining, hydrodynamic nika, da dai sauransu. Matsakaicin an yi shi ne da mahadi na musamman (kamar abubuwa masu kama da polymer) tare da kyawawan kwararar ruwa a ƙarƙashin ƙananan matsa lamba kuma gauraye da abrasives, kuma abrasives na iya zama foda na silicon carbide.
(4) Magnetic nika da goge baki
Magnetic niƙa da polishing shi ne don amfani da Magnetic abrasives don samar da abrasive goge a karkashin aikin wani Magnetic filin don nika workpieces. Wannan hanya tana da ingantaccen sarrafawa, inganci mai kyau, sauƙin sarrafa yanayin sarrafawa da yanayin aiki mai kyau. Tare da abrasives masu dacewa, ƙarancin saman zai iya kaiwa Ra0.1μm
Gyaran gyaran gyare-gyare a cikin sarrafa gyare-gyaren filastik ya bambanta sosai da gogewar da ake buƙata a wasu masana'antu. Magana mai mahimmanci, polishing na mold ya kamata a kira aikin madubi. Ba wai kawai yana da manyan buƙatu don goge kanta ba har ma da manyan ƙa'idodi don shimfidar ƙasa, santsi da daidaiton geometric. Ana buƙatar gyaran fuska gabaɗaya don samun fili mai haske
Ma'aunin sarrafa madubi ya kasu kashi huɗu: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063μm, yana da wahala a daidaita daidaitattun daidaiton geometric na sassa saboda polishing electrolytic. , ruwa polishing da sauran hanyoyin Duk da haka, da surface ingancin sinadaran polishing, ultrasonic polishing, Magnetic nika da polishing hanyoyin. ba zai iya saduwa da bukatun, don haka madubi surface aiki na daidai molds ne har yanzu mamaye na inji polishing.
