Description
塑料热压片一次性成形紋路的方法 技术领域 本发明涉及一种塑料热压片一次性成形纹路的方法，其广泛应用 于诸如电子或通讯产品的镜片、 按键或者视窗等加工领域。 背景技术 对于一些电子及通讯产品 （如手机 /小灵通镜片、 按键、 视窗）、 家用电器（如视窗面板、按键面板、装饰面板）等需给予相应装饰时， 一般以成型不同紋路方式为主要设计之一，而传统成形纹路的方法通 常以表面直接印刷、 表面喷涂、 直接电镀或双色注塑等， 而该些方法 是难以在各种曲面、 弧面或斜面上成形一致性的套色图样， 故传统工 艺显然不适合当今之需求。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of forming a texture of a plastic hot-pressing sheet at a time, which is widely applied to processing fields such as lenses, keys or windows of electronic or communication products. BACKGROUND OF THE INVENTION When some electronic and communication products (such as mobile phones/PHS lenses, buttons, windows), household appliances (such as window panels, button panels, decorative panels) and the like need to be decorated accordingly, the main design is to form different lines. One of the traditional methods of forming lines is usually direct surface printing, surface coating, direct plating or two-color injection molding. These methods are difficult to form a consistent color pattern on various curved surfaces, curved surfaces or inclined surfaces. The process is clearly not suitable for today's needs.
当前，于塑料片上成形紋路有以下几种情况，其一为 ^D( In-Mold Decorat ion )模内镶件注塑成型装饰技术， 其将已印刷成型好的装饰 片材放入注塑模内， 然后将树脂注射在成型片材的背面， 使树脂与片 材接合成一体固化成型的技术。 其二为頂 L (IN- MOUld- Lable)成型技 术， 其和 IMD大致相同， 只是注塑后 f l im就像冲压的料带一样拉出， 只是将印刷图案转印到塑胶件上。 其三为 IMR (In Molding Rol ler) 成型扶术， 就是将已印刷好图案的膜片放入金属模具 (mold)内， 通过 送箔机器自动输送定位，然后将成形用的树脂注入金属模内与膜片接 合， 使原来印刷在膜片上的图案与膜片分离， 而转移到跟树脂形成一 体的一种成形方法。 然而， 上述 IMD/IML均存在繁瑣的工艺流程、 生 产效率不高等缺陷。 而 IMR虽能够自动化、 批量生产的优势， 但是所 成型印刷图案层在产品的表面上， 厚度甚至只有几个微米， 印刷图案 层易磨损掉、 易褪色， 造成表面很不美观， 从而会导致大量不良品产 生。 发明内容 本发明主要目的在于提供一种塑料热压片一次性成形紋路的方 法， 其将热熔制片与振动压合之技术结合， 以一次性压制的加工方式 将产品制出， 使生产灵活， 流程缩短， 提高效率， 并大幅度提高良品 率及降低成本。 At present, there are several cases in forming a pattern on a plastic sheet, one of which is an In-Mold Decorat ion injection molding decorative technique, which puts a printed decorative sheet into an injection mold. The resin is then injected onto the back side of the formed sheet to join the resin to the sheet to form a solid curing technique. The second is the top L (IN-MOUld-Lable) forming technology, which is roughly the same as the IMD, except that after injection, the f l im is pulled out like a stamped strip, just transferring the printed pattern onto the plastic part. The third is IMR (In Molding Roller) forming technology, which is to put the printed film into a metal mold, automatically convey the positioning by the foil feeding machine, and then inject the molding resin into the metal mold. The film is bonded to the film to separate the pattern originally printed on the film from the film, and is transferred to a forming method which is integrated with the resin. However, the above IMD/IML has defects such as cumbersome process flow and low production efficiency. Although IMR can automate and mass-produce the advantages, but the formed printed pattern layer is even a few micrometers on the surface of the product, the printed pattern layer is easily worn away and fades, resulting in a very unattractive surface, which leads to a large number of Defective products are produced.
