After bonding to each other to produce a decorative film of a complete form, and then inserting the decorative film into an injection mold and injecting the injection molding is an injection molded article having a decorative film layer injection molded.

상기와 같이 별도로 제작한 필름을 사용하여 제작한 장식필름조각을 접합하여 장식필름을 제작한 후 금형내에 안치하여 사추품을 성형하면, 처음부터 하나의 필름만으로 제작한 장식필름으로는 얻을 수 없는 상당히 고급스럽고 외관이 미려한 사출성형품을 얻을 수 있다.If the decorative film is made by joining the decorative film pieces produced using the separately produced film as described above, and then placed in a mold and molding the four-hundred article, it is quite impossible to obtain a decorative film made of only one film from the beginning. It is possible to obtain injection molded articles with high quality and beautiful appearance.

두 종류 이상의 장식필름조각을 서로 접합하여 제작한 장식필름을 사용하는 본 발명의 사출성형품의 제작방법을 단계별로 살펴보면 다음과 같다.Looking at the step of the production method of the injection molded article of the present invention using the decorative film produced by bonding two or more kinds of decorative film pieces to each other.

본 발명의 장식용 필름층을 갖는 사출성형품의 제작방법은, Method for producing an injection molded article having a decorative film layer of the present invention,

합성수지 시트의 전면에 그림이나 문자 또는 색상 등과 같은 원하는 형상으로 보호잉크와 접착잉크 등을 인쇄하여 인쇄잉크층을 형성하고, 후면에 열용융접착제를 도포하여 장식필름원판을 제작하는 단계와;Forming a printing ink layer by printing a protective ink and an adhesive ink in a desired shape such as a picture, text or color on a front surface of the synthetic resin sheet, and applying a hot melt adhesive to a rear surface to produce a decorative film disc;

상기 장식필름원판이 용이하게 변형될 수 있도록 장식필름원판의 일측면 또는 양측면을 히터판으로 가열하고 가열된 장식필름원판을 음각 또는 양각형상의 형틀에 넣고 진공흡입 또는 공기압을 가하여 양각 또는 음각으로 성형하고 불필요한 부분을 제거하여 원하는 형상의 장식필름조각을 제작하되, 상기 장식필름조각을 두 종류 이상으로 제작하는 단계와;One side or both sides of the decorative film disc is heated with a heater plate so that the decorative film disc can be easily deformed, and the heated decorative film disc is placed in an intaglio or embossed mold, and is formed into an intaglio or intaglio by applying vacuum suction or air pressure. And removing unnecessary parts to produce decorative film pieces of a desired shape, wherein the decorative film pieces are produced in two or more kinds;

상기 두 종류 이상의 장식필름조각의 가장자리부위의 접합부를 접합하여 완전한 형태의 장식필름을 제작하는 제작단계와;A fabrication step of manufacturing a decorative film in a complete form by bonding the joints of the edge portions of the two or more decorative film pieces;

상기 장식필름을 사출금형에 삽입한 후 사출물을 주입하여 소정의 합성수지 사출품을 사출성형하는 단계를 포함하는 것을 주요 특징으로 한다.After inserting the decorative film into the injection mold is characterized in that it comprises the step of injecting the injection molding the injection molding of a predetermined synthetic resin.

상기 합성수지 시트는 일반적으로 ABS, PET, PVC, 폴리카보네이트, 아크릴 등과 같은 합성수지 재질이고, 상기 열용융접착제는 핫멜트(hot melt)와 같이 상온에서는 고체이나 일정온도 이상으로 가열하면 점성을 지닌 액체가 되는 공업용 접착제로서, 금형내에 주입되는 고온의 사출물과 필름층을 완전히 접합하는 역할을 한다.The synthetic resin sheet is generally a synthetic resin material such as ABS, PET, PVC, polycarbonate, acrylic, and the like, and the hot melt adhesive is solid at room temperature, such as hot melt, or becomes a viscous liquid when heated above a predetermined temperature. As an industrial adhesive, it serves to completely bond the hot injection product injected into the mold and the film layer.

상기 장식필름원판을 제작하는 단계나 장식필름조각을 제작하는 단계는 당업자에 의하여 용이하게 실시되고 있는 공지의 기술이다.The manufacturing of the decorative film disc or the manufacturing of the decorative film pieces is a well-known technique easily carried out by those skilled in the art.

상기와 같이 두 종류 이상의 장식필름조각의 가장자리부위의 접합부를 접합하여 완전한 형태의 장식필름을 제작하고, 제작된 장식필름을 사출금형에 삽입한 다음 고온의 사출물을 주입하면 장식필름 후면에 도포된 접착제가 녹으면서 사출품이 사출성형된다.Bonding the joints of the edges of two or more kinds of decorative film pieces as described above to produce a complete decorative film, insert the produced decorative film into an injection mold and then inject a high-temperature injection molding adhesive applied to the back of the decorative film The melt is melted and the injection molded product is injection molded.

상기 장식필름조각들을 사전에 접합하여 사출금형내에 삽입하는 것은 사출물이 주입될 때 사출물의 흐름에 의하여 필름조각들의 위치가 바뀌어 불량품이 발생하는 것을 방지하고 금형내에 보다 안정적으로 쉽게 삽입할 수 있기 때문이다.Bonding the decorative film pieces in advance and inserting them into the injection mold is because when the injection is injected, the position of the film pieces is changed by the flow of the injection material to prevent the occurrence of defective products and more easily insert into the mold. .

상기 장식필름조각 제작단계는 장식필름조각들이 접합된 상태에서 접합부 및 접합부 주변부의 단면이 사각형 또는 사다리꼴인 채널형 홈이 되게 제작되고, 또한 접합부는 홈의 바닥면 또는 측면으로서 장식필름조각이 겹쳐지는 형태로 제작되는 것이 바람직한 데, 이는 접합부의 경계선을 채널형 홈의 바닥면에 구성하면 사용 중에 접합부가 떨어지는 것을 방지할 수 있고 외관상 잘 보이지 않을 뿐만 아니라, 채널형 홈 자체도 상당한 미적 효과를 기대할 수 있기 때문이다.The decorative film piece manufacturing step is made so that the cross-section of the joint portion and the peripheral portion of the joint portion is a rectangular or trapezoidal channel groove in the state where the decorative film pieces are bonded, and the joint portion is overlapped with the decorative film fragment as the bottom or side of the groove. It is preferable to be manufactured in a shape, which is that when the boundary of the junction is formed at the bottom of the channel groove, the junction can be prevented from being used during use, it is not easily seen in appearance, and the channel groove itself can expect a considerable aesthetic effect. Because there is.

상기 장식필름 제작단계는, 열용융접착제가 도포된 후면이 밖으로 향하게 장식필름조각들을 엎어두고 안정적으로 접합할 수 있도록 장식필름조각이 안치되는 안치면과 필름을 진공흡착하여 고정할 수 있는 흡착공이 성형된 접합금형에 올려두고 접합부를 접합하는 것이 효율적이며, 상기 장식필름조각의 겹쳐진 접합부를 일정온도로 가열된 프레스로 압착하면 필름 후면에 도포되어있던 열용융접착제가 순간적으로 녹으면서 접합된다.In the decorative film production step, the adsorption hole is formed by vacuum adsorption of the settled surface and the film on which the decorative film pieces are placed so that the decorative film pieces can be reliably bonded to the rear side where the hot melt adhesive is applied to the outside. It is efficient to place the bonded parts on the bonded molds, and when the overlapped joints of the decorative film pieces are pressed with a press heated at a predetermined temperature, the hot melt adhesive applied to the back of the film is melted instantly.

또한, 상기 장식필름조각의 겹쳐진 접합부를 일정온도로 가열된 프레스로 압착하여 접합하는 대신에, 접합부를 초음파 용착하거나, 접합부 사이에 양면테이프 또는 일반 공업용 접착제를 개재하여 접합할 수도 있다.In addition, instead of pressing and joining the overlapped joints of the decorative film pieces by a press heated to a predetermined temperature, the joints may be ultrasonically welded or bonded through a double-sided tape or a general industrial adhesive between the joints.

또한 상기 장식필름조각 제작단계는 장식필름조각들이 접합된 상태에서 접합부 및 접합부 주변부의 단면이 사각형 또는 사다리꼴인 채널형 홈이 되게 제작되고, 또한 접합부는 홈의 바닥면 또는 측면으로서 양측의 단면이 서로 접하게 제작되고, 상기 장식필름 제작단계는 열용융접착제가 도포된 후면이 밖으로 향하게 장식필름조각들을 엎어두고 안정적으로 접합할 수 있도록 장식필름조각이 안치되는 안치면과 필름을 진공흡착하여 고정할 수 있는 흡착공이 성형된 접합금형에 올려두고, 상기 장식필름조각의 접합부를 바깥 쪽에서 단면테이프로 접합할 수 있다.In addition, the decorative film piece manufacturing step is made so that the cross-section of the joint portion and the peripheral portion of the joint portion is a rectangular or trapezoidal channel groove in the state where the decorative film pieces are bonded, and the joint portion is a bottom surface or side surface of the groove, It is made in contact with, and the decorative film production step can be fixed by vacuum-sucking the settled surface and the film on which the decorative film pieces are placed so that the decorative film pieces can be reliably bonded so that the rear side to which the hot melt adhesive is applied is turned outward. The adsorption hole is placed on a molded mold, and the joining portion of the decorative film piece can be joined with a single-sided tape from the outside.

본 발명에 있어서, 상기 접합부는 전체를 접할 수도 있으나 적당한 간격으로 일부만 가접합되어도 되는 데, 이는 사출성형시 장식필름조각들이 서로 떨어지지 않고 삽입된 정위치에 안치되어 있기만 하면 주입되는 사출물의 열에 의하여 열용융접착제가 녹으면서 접합부의 나머지 부분도 완전히 접합되기 때문이다.In the present invention, the joint portion may be in contact with the whole, but only a part of the joint may be temporarily bonded at an appropriate interval, which is heated by the heat of the injection molding injected as long as the decorative film pieces are placed in the inserted position without falling apart from each other during injection molding. This is because the molten adhesive melts and the rest of the joint is completely bonded.

상기와 같은 본 발명의 장식용 필름층을 갖는 사출성형품은 외관이 우수한 고품질의 사출성형품으로서, 자동차의 내장재나 전자제품의 케이스 등에 사용될 수 있으며, 상기 채널형 홈의 바닥면 또는 측면에 접합부를 구성하는 방법은 접합부가 겉으로 드러나지 않아 외관이 우수할 뿐만 아니라 접합부가 홈에 묻혀 보호되는 장점이 있으며, 접합금형과 프레스 등을 사용하는 접합방법은 자동화가 가능한 장점이 있다.The injection molded article having the decorative film layer of the present invention as described above is a high-quality injection molded article having an excellent appearance, and may be used in a car interior material or a case of an electronic product, and constitutes a joint part on a bottom or side surface of the channel groove. The method has a merit that the joint is not exposed to the outside and the appearance is excellent as well as the junction is protected by being buried in the groove, and the bonding method using the bonding mold and the press has the advantage of being automated.
