吸塑模具一般有石膏模、電鍍銅模和鋁模三種石膏模:用石膏在半濕的狀態下雕刻成型,然后烘干即成模具,石膏模成本低,易于修改,但石膏模精度不夠高,表面不光滑而且易碎不耐用,因此它常用來打佯、做電鍍銅模的模種或一些要求不高小批量生產的吸塑模具。鋁模:用鋁錠通過
機械(車床、銑床、CNC等)加工而成。鋁模精度高、表面光滑而且經久耐用,但價格非常貴,鋁模一般用在精度要求較高銅模達不到的吸塑產品上。電鍍銅模:用石膏模種制成樣品后,電鍍一層銅殼即為電鍍銅模,成本相對石膏模高,但比鋁模便宜得多,因其表面光潔耐用、低成本的優點,電鍍銅模是最常用的一種吸塑模具。二、吸塑材料的選擇吸塑產品的原材料只有塑膠片材,膠片厚度一般不超過1.5MM,常用的片材有:PVC、PET、PP、PS以及在此基礎上的植絨片材、鍍金片材和防靜電片材。PVC:最常用的吸塑材料,質軟、韌性強、可塑性好,可做成透明和各種顏色,常用透明PVC包裝電子、化裝品、玩具禮品等產品。PET(A-PET):質硬,韌性好、強度高、表面光亮、環保無毒,有透明和多種顏色的片材。缺點是PET高周波熱合比較困難,價格也比PVC貴很多,此材料常被要求產品高檔和環保的用戶取代PVCPS:密度小(質輕)、環保無毒,可塑性非常好,韌性差易脆,不可做成通明材料,因此只能做成底托類吸塑,因其易裂,此類吸塑不宜回收PP:材質特別軟,韌性好,環保無毒、耐高溫,常被做成餐飲器具或其他耐高溫產品的包裝;但其可塑性差,加工難度大,表面光澤度差,而且加工時顏色會變淺。PET-G:物理性質同A-PET差不多,但可以高周波熱合,其價格比A-PET還貴80%Clamshellmouldgenerallyhavecastmould,electroplatingcopperandaluminiumthreeWithgypsumplastermold:inhalfwetcondition,andtheniscarvedintoamolddrying,lowcost,easytoplastermoldmodification,butcastsprecisioninsufficienttall,smoothsurfaceandfragilenotdurable,soitisusedtoDaYang,electroplatingcoppermoldorsomehighvolumeproductionrequirementsofclamshellmould.Aluminium:usealuminumthroughmechanical(lathe,millingmachine,CNCmachining,etc.).Aluminiumprecision,smoothsurfaceanddurable,butthepriceisveryexpensive,aluminiumusuallyinahigheraccuracythancopperclamshellproducts.Electroplatingcopperwithaplastermold,madealayer,electroplating,afterthesamplefortheelectroplatingcopperbrassshells,costishigh,butrelativelycastsaluminiummuchcheaperthanasmoothsurface,becauseofitslowcostadvantages,durable,electroplatingcopperisoneofthemostcommonkindofplasticmould.Second,thechoiceofmaterialsTherawmaterialonlyclamshellproducts,plasticsheet,filmthicknessgenerallydoesnotexceed1.5MM,commonsheet:PVC,PET,PP,PS,andonthebasisofflockingsheet,gold-platedsheetandanti-staticsheets.PVC:themostcommonlyusedclamshellmaterials,soft,strongtoughness,goodplasticity,maketransparentandvariouscolors,commontransparentPVCpackaging,cosmetics,electronicproductssuchastoysandgifts.PET(APET):qualitativehard,andhighstrength,toughness,goodsurfacebrightness,environmentalprotection,transparentandnon-toxiccolorsofthesheet.WeaknessisthePEThigh-frequencyking,thepriceismoredifficultthanPVCexpensive,thismaterialisoftenmuchhigh-gradeproductsandenvironmentalrequirementsofusersreplacePVCPS:densityissmall(lightgreennontoxic,plasticity,verygood,toughness,poorbrittlematerial,thereforecanonlymakelitDeTuomadeofplastic,becauseitseasilycrack,suchclamshellshouldsnotberecycledPP:softqualitativespecial,toughness,goodgreennontoxic,hightemperatureresistant,oftenmakecateringapplianceorotherhigh-temperaturepackingofproducts,Buttheplasticity,processing,surfaceglossandcolorprocessing,willgrow.G:thephysicalpropertiesofPET-withAPET,butcanbesimilar,thehighfrequencythanAkingalsoPET 公司堅持務實、求精、創新的企業精神。嚴把生產環節,加強技術改進,實行制度化,規范化制度管理,形成優秀的開發能力、生產能力、經營管理能力。 公司宗旨 質量第一,顧客至上 誠接國內外業務,歡迎廣大客戶前來公司咨詢、洽談! 聯系方式: 朱小姐TEL:020-82260356 FAX:020-82686172Mob:13929556341E-mail:zhuxiaoqing1220@163.com MSN:zhuxiaoqing1220@hotmail.com QQ:411895015中文網站:http://www.lanbingongsi.com.cn/英文網站:http://gzjs.en.alibaba.com公司地址:廣州市新塘新墩下墩工業區一棟四樓
