Abstract
The invention discloses a process for manufacturing patterns on shells of mobile phones. The process includes performing injection molding; spraying primer; baking the primer, gasifying the primer; spraying finish paint; obtaining finished products. The process has the advantages that problems of deterioration of adhesion among coatings and easiness in premature paint removal when patterns are manufactured on the surfaces of products by the aid of a spraying technology can be solved; problems that printed patterns are often quite stereotyped and are low in ornamental value after the patterns are printed on shells of mobile phones by the aid of a screen printing or transfer printing technology can be solved; technical problems of high limitation when patterns are manufactured by the aid of a spraying method or a screen printing method or a transfer printing method or the like and incapability of accurately realizing desired artistic effects in case of curved patterns or large patterns or complicated patterns can be solved.
Description
?
Technical field
The invention belongs to the design producing field above phone housing, be specifically related to a kind of phone housing manufacturing technology of patterns.
Background technology
Mobile phone, as a kind of important communication tool, has more and more been popularized in daily life, and mobile phone market is also being contained great potential.Along with the development of mobile phone market, consumer is also more and more higher to the requirement of mobile phone, and therefore, the trend that mobile phone is produced will be also the appearance design of more focusing on mobile phone.Cell phone appearance determines by phone housing to a great extent, and phone housing is generally plastic shell, and phone housing colour match, luster effect etc. all produce a very large impact the visual effect of phone housing.
Existing on phone housing the method for pattern-making be mostly the methods such as spraying, silk-screen and bat printing.
Phone housing is made by plastic parts mostly, Mobile phone plastic part spraying is industry of exquisite fineness of the highest, the product requirement of technical requirement in plastic parts spraying, and in Mobile phone plastic part spraying process, paint film generally there will be following four kinds of failure modes: interfacial failure, the paint film that paint film self is assembled destruction, paint film and glue part assembles and intermixing destruction, glue part embrittlement (ground destruction).At present, traditional Mobile phone plastic part spraying coating process complexity, is pigment to be added on the bottom and middle level of coating, to reach the object that realizes color the processing method of mobile phone color of shell.Owing to pigment being added to two coatings, make pigment consumption larger, spraying number of times is more, not only reduce production efficiency, also increased production cost, also reduced in addition the adhesive force that is coated with interlayer, being prone to the phenomenon of falling to paint too early affects the quality of phone housing.
Employing silk-screen or transfer-print technology, after pattern is printed on to phone housing, the pattern of printing is often very stiff, does not have very strong sight.
Often limitation is very large in pattern-making to adopt the method such as spraying, silk-screen and bat printing, when relating to the pattern of curved surface pattern or large-scale pattern or more complicated, often can not make very accurately the artistic effect of wanting.
In Chinese invention patent description CN102671844A, disclose a kind of Mobile phone plastic part spraying coating process, described spraying coating process comprises following step: assembling oil spout fixture, cleans electrostatic precipitation, priming paint spraying, finish paint oil spout.Described spraying coating process utilizes in priming paint spraying step and form even, continuous prime coat on Mobile phone plastic part surface, realizes Mobile phone plastic part and presents required color effects.Utilize the color effects forming in priming paint lacquer spraying technique step more stiff.
A kind of UV curable ink composition that can bat printing is disclosed in Chinese invention patent description CN101993629A, while using transfer-print technology that this based composition is printed on above phone housing, due in the time that this ink composite is attached to mobile phone shell, its adherence is poor, the phenomenon that there will be pattern edge to shrink after solidifying, further cause dim pattern unclear, cause the fraction defective of product very high.
Summary of the invention
The phenomenon that is prone to too early paint in order to solve existing employing spraying technology affect the quality of phone housing and employing silk-screen or transfer-print technology, after pattern is printed on to phone housing, the pattern of printing is often very stiff, do not there is very strong ornamental technical problem, the invention provides a kind of phone housing manufacturing technology of patterns.
Described a kind of phone housing manufacturing technology of patterns, it comprises the following steps:
1) injection moulding: inject plastic cement in mould by injection machine, obtain phone housing plastic parts;
2) priming paint spraying: priming paint is sprayed on phone housing plastic parts, forms spraying coating line;
3) baking priming paint: use heating tool to toast priming paint;
4) priming paint gasification: use laser radium carving machine that priming paint is gasified, obtain predetermined pattern;
5) finish paint spraying: finish paint is sprayed on phone housing plastic parts according to predetermined pattern;
6) finished product: the phone housing plastic parts to the complete finish paint of spray in step 5) is dried processing.
In order better to obtain spraying effect, the phone housing surface through described step 5) processing is sprayed to the processing of UV layer process.
As a kind of preferred version, in described step 1), plastic cement is thermoplastic plastic.
Preferably, when in described step 4), laser radium is carved the radium-shine laser of machine, the radium-shine time is 5-10 second.
More preferably, when in described step 4), laser radium is carved the radium-shine laser of machine, radium-shine angle is 30-60 degree.
Further, when in described step 4), laser radium is carved the radium-shine laser of machine, radium-shine temperature is 100-120 degree Celsius.
Further, when the radium-shine laser of described laser radium carving machine, optical maser wavelength is 638-650nm.
Preferably, when priming paint baking in described step 3), at interval of baking in 5 minutes once, toast altogether 4 times.
More preferably, when priming paint baking in described step 3), disposable baking 15 minutes.
More more preferably, when priming paint baking in described step (3), baking temperature is controlled at 80-100 degree Celsius.
The invention solves and adopt spraying technology coating in the time of product surface pattern-making to reduce the adhesive force that is coated with interlayer, be prone to too early the phenomenon of paint and adopt silk-screen or transfer-print technology, after pattern is printed on to phone housing, the pattern of printing is often very stiff, does not have very strong sight; Solved methods such as adopting spraying, silk-screen and bat printing often limitation is very large in pattern-making simultaneously, when relating to the pattern of curved surface pattern or large-scale pattern or more complicated, often can not make very accurately the technical barrier of the artistic effect of wanting.
