reduce cost and 工时: IMD need sleeve/set mold, other has process more sleeve/set mold, can remove one-time as 业程序 人 force and 工时, reduce system cost and cost.

IMD mold design and product molding key points

as is upper mold manufacturing new process, IMD mold in inner development 也越 越迅 speed. 就东莞 区而言, 我本人觉 upper 规模, technology formed and quality excellent 良 厂家 also is comparison less; 各厂家 between technology 交流几乎没 has, for technology 保密, from development process basic 处于探索 stage/phase.

IMD mold core technology main/primary is sheet/slice manufacturing process, it in Japan, Germany several large type enterprise 里. key/critical high temperature resistance ink, wear resistant, ultra- transparent coating material also is main/primary Imported.

本人也 is rigid rigid 接触IMD mold, has design 方面 心, has can can is very positive 确, industry inner 人士批评指 positive.

一, brief introduction:

1, IMD has large type, 即IMLIMD, upper is IMD.
IMD(即In-Mould-Decoration)
  has types classification:
  its is IMD, it is is screen printing has FILM放 to plastics mold 里进行 injection molding. 此FLIM large can separation is 三层, 基材（ generally is PET）--- INK(ink)--- wear resistant material (more is types 特殊 胶).
当 injection molding formed rear, Film and plastics melt is 一体, wear resistant material in most outer 面.
in machine 显示屏 more using/adopting this type of process, plastics material more is PC, PMMA, PBT and other, it main/primary has wear resistant and resistant function.
因PC thick, can use filament 网印, therefore relatively coarse 糙.

also has types 叫IML(IN-MOUld-Label) technology, and IMD large same, is injection molding rear flim就像冲 pressure material belt/tape 一样拉出, is will printing 图案转印 to plastics parts upper, also inner 转印.
Flim generally is PET material, very electrical 影时 胶 sheet/slice, also 叫链子（FOIL）; PET thin, can use 胶版印, very fine 腻, especially electroplating and transparent, metal and surface fine 腻纹理都 very good.

   2, product production process/workflow
   3, detailed production process/workflow lower （实战 experience, exclusive 奉献）:

     large material —〉 hot type —〉裁 small material —〉冲孔定位—〉 printing —〉 solid 化—〉 semi formed product 检查—〉贴保护 film —〉点眼—〉冲切—〉 molding —〉 injection molding —〉 in 线检验—〉贴保护 film —〉修 gate —〉 semi formed product 检验—〉背胶—〉 formed product 检验—〉贴保护 film —〉 formed product packaging

注: upper is most comprehensive 工序; 当然, simple product use to its in separation 工序!

三, IMD mold design and molding key points

1, mold sink marks rate issues
  generally ABS, PMMA sink marks is 0.5%, 如做IMD mold, product surface need cover/cap 一层PET film, 显然两者 hot shrinkage rate different.

按本人 experience, IMD mold mold product its sink marks relatively mold small, 取0.3% comparison combined 适. is, injection molding plastics by sheet/slice 材包裹, for plastics shrinkage to retardant function.

2, sheet/slice issues
    sheet/slice is IMD mold formed key/critical; is most is complex issues. lower separation 几项进行 analysis:
a, 材质, ink
generally sheet/slice 材 材质 is PET, has PC, PMMA sheet/slice 材. 但PET molding and processing relatively excellent 良. surface gloss degree, wear resistance to requirements, therefore by application 材质. thick 0.125mm PET sheet/slice is most hot sheet/slice 材之一.

ink, is printing raw materials, requirements wear resistant, high temperature resistance, 调配, screen printing as 业方便.

b, made sheet/slice 材（裁剪, hot molding ）

generally process process/workflow is:

sheet/slice selection ---〉 printing （工 tool: 菲林, filament machine; key points: ink selection, sheet/slice 材定位）
---〉贴保护 film
---〉 outer 形冲裁（工 tool: 刀模; key points: sheet/slice 材定位）
---〉贴保护 film
---〉 hot type （工 tool: hot type machine; key points: temperature degree control ）
---〉贴保护 film
请留意, 贴保护 film is ratio can less process, 请保护 and anti function; film generally use PE film.

in hot type step/link, temperature degree control very important, 掌握不 good, easy make sheet/slice deformation, waste rate high.

hot type machine upper, lower has add hot sheet/plate, in as maintain temperature degree. 移动式 add hot sheet/plate in sheet/slice rear, to sheet/slice 材顶部 for sheet/slice 材进行 preheating, make its soft, can clamping hot type 处理!

c, sheet/slice and type 腔 配 combined
      sheet/slice dimensions need ratio most 终 部 parts dimensions small 一点点. -------- most important 原则

generally lower, 建议: sheet/slice dimensions need ratio parts dimensions mono small 0.02至0.03mm
   
this 样, sheet/slice 材置入 type inner is easy, can full 伸展开. has 褶皱, formed product defect.

3, sheet/slice molding mold design key points

a, use product 图, in Pro/e（ or other 3D soft parts ）按 sheet/slice thick degree, will product surface toward inner 偏置, to sheet/slice 材 3D图. ---- most 麻烦 工 as!

b, sheet/slice 材 3D图, will its 展开, as sheet/slice 材 刀模, and other.

c, sheet/slice 材3D图 separation 模

d, manufacturing mold
 
4, molding mold design key points
  need will sheet/slice to type inner injection molding, therefore, in design upper and 普通通 mold has different 方. lower its features analysis:
a, gate
不 using/adopting separation type 面直接进胶 methods!
causes: in separation type generally has sheet/slice 材, 直接进胶 will sheet/slice 材冲开, formed product in gate 四周会 has gas marks, sheet/slice by 冲起皱, screen printing 图案亦会 by 冲开一 口子!
generally need using/adopting 顶针潜 water methods, or 牛角潜 water 入胶（ rear 模需做两镶 parts, 各打牛角 semi 边胶位）

b, separation type and 碰穿面 requirements
separation type 面不 像普通 mold 一样直接 from 胶位边顺延拉出, to toward lower 拉出3---5mm（ need 做3 degree above demolding 角） again as separation type 面. this 样, front rear separation type is scratch 穿面!

  is what need this 么麻烦呢? causes: is sheet/slice 材不会完 full and type 腔准确 吻 combined rigid good ratio type small 0.02mm. tube/pipe is machine or 手工置入, can can full filament 不差 放 to 位.
therefore, scratch separation type 面就像一 罩子般, sheet/slice 材 罩住, 起定位 function.
  同样, has 碰穿面也 need is scratch 穿面!
below/following is 一款镜 sheet/slice IMD separation 模图:
 
   attention/notes, in powder color is 特意拉出 scratch 穿面!
   is sheet/slice 材 定位 non important, in mold upper also need again its it method. ratio 如, in 碰穿面, front 模镶两根针, to rear 模, sheet/slice upper long material 出 并 for mold 做两 定位孔. in front 模放入 sheet/slice 材时, sheet/slice 材卡入镶针 upper, from can very good sheet/slice 材定位 in front type inner.
clamping 时, is 碰穿面 by is scratch 穿面, front 模就像一 刀一样 sheet/slice more 余 定位 material remove （就算不 is scratch 穿面, 同样也 can to function ）. most to good IMD formed product.
如 lower 图:

c, sheet/slice in 啤塑时 定位
main/primary 靠自动 plant/unit, 定位销, true and other.
如 using/adopting outer control and other.
currently, upper development has IMD sheet/slice 材定位 new technology: electrical 荷.
即 utilizing electrical sheet/slice 材牢牢 吸附 in type inner. 如此项 technology by application, will large improve/increase IMD production efficiency!

（ currently, inner also has research technology, 本人认 is for research, 一定会 very has front 途! ）

small 结:
IMD mold in structure upper and mold has especially difference, main/primary in sheet/slice 材 定位方面.
IMD molding and molding processing in 架模, equipment 安装, molding conditions and other has relatively is requirements,另 mold and mold structure 不一样, in adjustment 开关模时应 especially attention/notes.
