The decoration method of plastic surface treatment overview the process of the decoration processs ---painting .---electroplating ---in mold decoration---printing ---texture (brush) painting batch panting line ,continuous painting line the content of the paints resin ,solvent , pigment ,additive . the normal resin content the following resin alkyl , phenolic ,amino sugar , acrylic ,epoxy resin ,polyurethanes p?liju?riθein] the content of the pigment . plasmid ,bedye, special paint the type of additive stabilizer ,dispersant ,anti-setting agent the drying method of paints volatilization , syncretize, oxidation, crosslinking, 架橋反應ultraviolet radiation. the thickness of the painting CASHEW 10～15μm AKZO NOBEL 20～25μm 大世紀 20～25μm the problem of the painting the spary painting is too thick the particle of the paints is so big . Degree of uniformity is not good The base material is not proper The panits affect the intensity . Stain in the paints imd (in mold decorating ) the steps of IMF Prepare and make some film is called liminate . print the graphics inks and gry thoroughly . remove the ist surface laminate hot air forming (injection ) UV curing for increasing it resistant scratch . the material of the film PC ,PMMA , Polyester.PET . the adventages and disadvantage use the PC Benefits Clarity Ease of cutting/printing Compatibility with moulding resin Disadvantages Form precision (± 0.3mm) Flexibility (embossed switches) Not inherently weatherable Chemical resistance Poor pencil hardness Use the PMMA Benefits Clarity Good forming behaviour (± 0.15mm) Excellent weathering Pencil hardness Disadvantages Brittle (cutting handling problems) Potential adhesion problems to resin Form can relax in moulding tool Chemical resistance Use the PET Benefits Excellent fle
