IML process introduction need:本文 main/primary introduction IML molding principle and process, for IML and IMD process as comparison analysis, summary 出IML process excellent disadvantages. material upper 收集整理而 formed,供 large 家参考一.IML concept IMD（In-Mold Decoration） is types in injection molding parts injection molding parts mold inner 放置Film film decoration plastics appearance surface new technology. currently IMD has types manufacturing methods, types is printing good Film film made as formed ring 滚筒卷状 belt/tape,安装 to injection molding parts machine and injection molding parts injection molding parts mold inner,象 label Label贴 to front upper full 自动 循 ring belt/tape 移动式 production 出;即人称之 is IMD(in injection molding parts mold inner injection molding parts ）. types is Film film printing good molding machine Forming molding, again 经 剪切 rear to injection molding parts injection molding parts mold inner production 出. 即称之 is IML（ in injection molding parts mold inner film injection molding parts ）. 此Film generally can separation is 三层: 基材（ generally is PET）, ink 层（INK）, combined material （ more is types bonding 胶）. injection molding parts formed rear, through bonding function make Film and plastics 紧密结 combined melt is 一体, due to positive surface wear resistant film PET in most outer 层, has wear resistant and resistant function, its surface hardness can to 3H, but also 会越摸越亮. its in injection molding parts material more is PC, PMMA, PBT and other and other. lower 图: 二, IML process 工序裁 material ---平面 printing --- ink drying solid 定---贴保护 film ---冲定位孔--- hot molding ---剪切 outer 围形状---材 material injection molding parts molding process process/workflow lower 图: specific 说明如 lower: 1)裁 material: film Film裁剪 formed already design good dimensions block, printing, molding use. 2)平面 printing: according to requirements 图标, manufacturing formed 菲林网, in good film Film方形 block upper printing 图标, 文字. 3) ink drying solid 定: printing good film Film方形放置 in high temperature 烤炉里 drying, is solid 定IML ink. 4)贴保护 film: in 冲定位孔工序时弄花 already printing good film Film surface, has 时需贴 upper mono or di 层保护 film. 5)冲定位孔: hot molding 定位孔一定 need 冲准. 剪切工序 定位孔 has need 事先冲孔. 6) hot molding （ high pressure or copper 模）: printing good film add hot rear, use high pressure machine or copper in preheating lower molding. 7)剪切 outer 围形状: molding good film waste material 剪切掉. 8)材 material injection molding parts: molding rear front 模立体形状一模一样 film to front upper, injection molding parts 出IML formed product.
