Description
Technical Field
The invention relates to the field of mobile phone protective sleeves, in particular to a production process of a protective sleeve formed by integrally placing a magnet array in a mold and performing injection molding.
Background
With the popularity of cell phones in young communities, almost every young fashion-seeking individual desires to have a unique cell phone. Beauty treatment of mobile phones is gradually becoming a way for them to show their personalities; in order to meet the trend, mobile phone protective case manufacturers have also provided a plurality of products with more excellent workmanship and more unique color patterns, so that the types of the mobile phone protective cases are more diversified, and the mobile phone protective cases are divided into leather, silica gel, cloth, hard plastic, soft plastic cases, velvet, silk and the like according to the texture; the protective sleeve plays a role in protecting the mobile phone to prevent hard objects from leaving scratches on the screen or the body of the mobile phone; various patterns can be arranged on the protective sleeve in a DIY mode, and the protective sleeve has the functions of beautifying and fashioning; the silica gel protective sleeve can prevent the fingernail from scratching and wearing off due to long-time contact with the key, and has the function of protecting the screen and the key; the silica gel protective sleeve also has the anti-skid function.
The protective sheath is external magnet to current magnetism, fixes magnet and cell-phone cover each other through double faced adhesive tape, need place the recess of magnet at the interior post-processing of cell-phone cover, then the double faced adhesive tape is as the fixed magnet of medium, and the shortcoming of this kind of fixed mode is: the working procedures are multiple, and the processing cost is high; in extreme cases or after long-term use, the chemical properties of the double-sided adhesive are unstable, and the magnets are easy to fall off or mutually adsorbed together due to the reduction of the adhesiveness of the double-sided adhesive; the glue site distance between the groove and the surface of the protective sleeve is too thick to reduce magnetism. It laminates each other to need multiple material, and material self tolerance causes uncontrollable clearance greatly, influences the pleasing to the eye degree and the durability of product, consequently, it is necessary to provide a new and puts magnet array in mould plastics integrated into one piece's protective sheath and solves above-mentioned technical problem.
Disclosure of Invention
In order to solve the technical problem, the invention provides a production process of the protective sleeve which is convenient to process and firm in adhesion and integrally formed by placing the magnet array in the mold and performing injection molding.
The invention provides a production process of a protective sleeve integrally formed by placing a magnet array in a mould through injection molding, which comprises the following steps:
1) fixing the decorative ring on one side of the PET sheet in a screen printing, printing or electroplating mode;
2) adhering the high-temperature-resistant powerful double-sided adhesive to the surface of the decorative ring, and adhering the high-temperature-resistant magnet to the high-temperature-resistant powerful double-sided adhesive to be adhered with the decorative ring;
3) positioning the surface of the PET sheet with the decorative ring in a mold cavity by utilizing a positioning hole on the PET sheet and a positioning column of a front mold of the mold;
4) injecting glue into the mold at high pressure through the glue inlet hole, and injecting the glue into the machine shell to integrally form the PET sheet, the magnet and the machine shell;
5) and a hole is formed in the position, corresponding to the mobile phone camera, of the PET sheet and the shell, so that the PET sheet is sleeved outside the mobile phone when in use and is attached to the mobile phone.
Compared with the related art, the production process of the protective sleeve integrally formed by placing the magnet array in the mold and performing injection molding has the following beneficial effects:
the invention provides a production process of a protective sleeve which is integrally formed by placing a magnet array in a mould and injecting, simplifies the working procedures, eliminates the working procedures of multi-channel post-processing, slotting a mobile phone, placing a magnet, attaching a decorating part and the like, reduces the cost, improves the yield, reduces the working procedures and saves materials at the same time, thereby reduce cost, reduce environmental pollution, magnet and protective sheath shaping together, can solve because of the fixed protective sheath of double faced adhesive tape and the magnet comes unstuck, adsorb each other, the scheduling problem drops, the durability of product has been improved and application range has been enlarged, can not produce the magnet scheduling problem that drops because of the double faced adhesive tape viscidity that cold or high temperature lead to reduces, magnet snap-on is in ultra-thin PET sheet inboard, make its reduce with the distance of the other magnetism suction accessories in the protective sheath outside, magnetic force between the two attracts more firmly, can improve magnet magnetism by a wide margin.
