Abstract
The invention discloses an injection molding process of an in-mold integrated deformed injection molding part. The injection molding process comprises the steps of designing a graph, filming, performing plate-making (silk screen), printing and cutting materials (plastic materials such as PC (polycarbonate)\PET (polyethylene glycol terephthalate)\PVC (polyvinyl chloride)\PP (polypropylene)\PMMA (polymethyl methacrylate)), printing (silk screen) and drying at high temperature, performing plastic molding, cutting peripheral shapes, and injecting the materials. According to the injection molding process, the in-mold integrated deformed injection molding part is manufactured by adopting the process, a pattern printing layer is positioned between an outer wear-resistant layer and an injection molding material, an outermost layer and the pattern printing layer are fused with the injection molding material through special glue and printing ink to form a whole body, and the in-mold integrated deformed injection molding part is scratch-proof, wear-resistant, moisture-proof, bright in color, diversified in image-text, strong in three-dimensional sensation, good in glossiness and long in service life; due to the integrated structure, the three-dimensional sensation is good and the safety is high; the environment-friendly materials and the environment-friendly printing ink are adopted; the ROHS (Restriction of Hazardous Substances) standards are met.
Description
Technical field
The present invention relates to special-shaped injection moulding process in a kind of film, relate in particular to the special-shaped moulding Shooting Technique of one in a kind of film, solve profiled plastic goods in injection moulding field and cannot carry out a kind of new technology of producing in film.
Background technology
In at present domestic film, injection moulding production technology remains single: can only produce the making as simple shapes such as plane, taper, semicircles.Especially in the face of the printed decoration technology of complicated 3D moulding moulding is still blank.
Traditional injection moulding part is because traditional processing technology makes it have following shortcoming:
1, after injecting products completes, pattern is printed on moulding surface, and poor adhesive force easily fades, do not possess scratch resistant, abrasionproof, etc. ability, service life is short;
2, adopt prilling, make look mother and carry out injection moulding later, color is single, and can not be configured in strict accordance with order volume, and waste is serious.
3, because injection moulding and printing are separately to carry out, non-one-body molded, third dimension is poor, poor stability;
4, moulding adopts not environmental protection of lacquer spraying technique, pollutes large.
5, Shooting Technique in original film, shape is single, can not solve the printing issues of special-shaped injecting products.
At the processing technology this part to moulding, need to significantly improve, so that moulding avoids occurring the problems referred to above.
Summary of the invention
Object of the present invention is just to provide in order to address the above problem the special-shaped moulding Shooting Technique of one in a kind of film.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The special-shaped moulding Shooting Technique of one in film, comprises the following steps:
(1) design configuration: use on computers the contents such as pattern, icon, word of professional graphic design software design customer requirement according to customer requirement, export final electronic drawings and archives, enter next step;
(2) slice: the ratio that the electronic drawings and archives designing is separated to every kind of color automatically by film film-discharging machine is produced respectively the various film substrates (film) that need, and enters next step;
(3) plate-making (silk screen): stand-by silk-screen plate is carried out to the preparations such as degreasing, flushing, coating, oven dry, then film substrate is located respectively and is attached on half tone according to color difference, by punching version machine, printer, produce the silk-screen plate that printing needs, enter next step;
(4) printing cut out material (PC PET PVC PP the plastic material such as PMMA): carry out as required cutting shape, unnecessary abandons, and enters next step;
(5) printing (silk screen): use response type ink and silk-screen plate by screen process press print the images to PC PET PVC PP on the plastic material substrate such as PMMA, enter next step;
(6) hyperthermia drying: the printed base plate cutting is placed in high temperature baking oven and is dried, and object is cured printing ink difficult drop-off, enters next step;
(7) plastics sucking moulding: the special mould of printed base plate being put into Packing Machine carries out plastics sucking moulding, enters next step;
(8) cut peripheral shape: the printing module waste material after moulding is cut off, enter next step;
(9) material injection moulding: the printing module after moulding is put into the special mould of injection machine, injected finished product through 220 ℃.
Particularly, in step (9), the printing module after moulding is put into the special mould of injection machine, through 220 ℃ of high-temperature injection, gone out finished product.
Beneficial effect of the present invention is:
The present invention is the special-shaped moulding Shooting Technique of one in a kind of film, and the special-shaped moulding of the interior one of film that uses this technique to produce, can be that any shape also meets and realizes the requirements such as colored printing.Pattern printed layers is between outer wearing layer and shell, and outermost layer and pattern printed layers are melted into a whole by special glue and ink and shell, have ability scratch resistant, wear-resisting, beautiful in colour, that picture and text are diversified, glossiness is high, long service life; Owing to being one-body molded, third dimension is good, and security is good, adopts environment-friendly materials, and environment-friendly ink, meets ROHS standard.
The specific embodiment
The present invention is the special-shaped moulding Shooting Technique of one in a kind of film, comprises the following steps:
(1) design configuration: use on computers the contents such as pattern, icon, word of professional graphic design software design customer requirement according to customer requirement, export final electronic drawings and archives, enter next step;
(2) slice: the ratio that the electronic drawings and archives designing is separated to every kind of color automatically by film film-discharging machine is produced respectively the various film substrates (film) that need, and enters next step;
(3) plate-making (silk screen): stand-by silk-screen plate is carried out to the preparations such as degreasing, flushing, coating photosensitive material, oven dry, then film substrate is located respectively and is attached on half tone according to color difference, by printer, expose, then develop, produce the silk-screen plate that printing needs, enter next step;
(4) printing cut out material (PC PET PVC PP the plastic material such as PMMA): carry out as required cutting shape, unnecessary abandons, and enters next step;
(5) printing (silk screen): use response type ink and silk-screen plate by screen process press print the images to PC PET PVC PP on the plastic material substrate such as PMMA, enter next step;
