The plastic housing product is a product manufactured by the plastic housing manufacturing method.
Description
[technical field]
The present invention relates to a kind of plastic casing preparation method and products thereof, be specifically related to a kind of plastic casing preparation method that adopts high strength high-temperature resistant in-mold decoration film and products thereof.
[background technology]
The development trend of 3C Product (electronic product, communication product, consumer product) is to slimming, lightweight and Strengthening and Toughening future development at present.
IMD(In Mold Decoration, in-mold decoration) technology is surface decoration technique at present international in fashion, its surface is sclerosis transparent membrane, centre is printing pattern layer, the back side is injection molded layers, because ink in centre, can make product prevent that surface from being scratched and meeting rub resistance demand, and can keep the distinct of color and fugitive color not.IMF(In Mold Film, the injection moulding of in-mold film mold insert) be a kind of technology in IMD.
At present ultra-thin of Ultrabook() plastic casing that adopts is that high rigid material (hot strength is 160MPa, and bending modulus is more than 12GPa) is by the high low temperature plastics forming technique of RHCM() obtain for example PA+50%GF.This high rigid material outward appearance processing mode is mainly sprays paint or texture processing, but the processing procedure that sprays paint exists environmental issue, and cost is high.In addition, high rigid material forming temperature is 290～330 DEG C, and forming temperature is higher, and traditional IMF film adopts PET film or the PC film cannot be high temperature resistant and play strengthening action.
In view of this, be necessary to develop in fact a kind of plastic casing preparation method, this plastic casing preparation method, in conjunction with high rigid material and special IMF film, overcomes above-mentioned non-refractory and can not play strengthening action defect, makes it obtain slimming, lightweight, Strengthening and Toughening and shell attractive in appearance.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of plastic casing preparation method, this plastic casing preparation method, in conjunction with high rigid material and special IMF film, overcomes above-mentioned non-refractory and can not play strengthening action defect, makes it obtain slimming, lightweight, Strengthening and Toughening and shell attractive in appearance.
In order to achieve the above object, plastic casing preparation method of the present invention, it comprises the following steps:
(1) provide a high-temperature resistant membrane, by this high-temperature resistant membrane punching location;
(2) screen printing ink layer on described high-temperature resistant membrane, to form IMF film;
(3) by described IMF high-pressure film forming;
(4) carry out die-cut to the IMF film after high-pressure molding;
(5) the IMF film after die-cut is placed in to the high rigidity plastics of injection mold injection moulding, in the time of injection moulding, makes the paramount rigidity plastics product surface of IMF film bat printing.
Alternatively, in described step (1): high-temperature resistant membrane layer is high temperature resistant reaches 305 DEG C, and hot strength is greater than 200Mpa.
Alternatively, in described step (1): the thickness of high-temperature resistant membrane is 0.08mm～0.30mm.
Alternatively, in described step (1): high-temperature resistant membrane is nylon PA4T, PA6T or PA9T.
Alternatively, in described step (5): the bending modulus of high rigidity plastics is greater than 8Gpa.
Alternatively, in described step (5): high rigidity plastics is PA or PPS.
In addition, the present invention also provides a kind of plastic casing product, and it is the product producing after described plastic casing preparation method is made.
Alternatively, the thickness of described product is 0.6mm～1.2mm.
Compared to prior art, plastic casing preparation method of the present invention and products thereof, by the surface to the high rigidity plastics product of injection mo(u)lding by the film bat printing of high temperature resistance and high strength, make plastic product except reaching the appearance requirement of fashion, and can ensure that product has certain hardness, make product meet slimming, lightweight, Strengthening and Toughening and requirement attractive in appearance.
[brief description of the drawings]
Fig. 1 illustrates the flow chart of steps of plastic casing preparation method one preferred embodiment of the present invention.
[detailed description of the invention]
For object of the present invention, method step and effect are had to further understanding, be now described with reference to the accompanying drawings as follows:
Refer to shown in Fig. 1, plastic casing preparation method of the present invention, it comprises the following steps:
Step 110: provide a high-temperature resistant membrane, and pre-baked to this high-temperature resistant membrane, pre-baked after by this high-temperature resistant membrane punching location; Wherein, this high-temperature resistant membrane is high temperature resistant reaches 305 DEG C, hot strength is greater than 200Mpa so that the product of wanted moulding is played to strengthening action, and the thickness of this high-temperature resistant membrane is 0.08mm～0.30mm, this high-temperature resistant membrane can be nylon PA4T, PA6T or PA9T, on this high-temperature resistant membrane, can do various lines processing according to demand;
Step 120: screen printing ink layer on described high-temperature resistant membrane, form IMF film, and after printing ink layer, toast this IMF film, this ink layer can be directly transparent hardened layer, or according to shades of colour patterned layer and the hardened layer of customer demand;
Step 130: in drawing forming mold by described IMF high-pressure film forming, to form needed three-dimensional shape;
Step 140: in die cutting die, the IMF film after high-pressure molding is carried out die-cut, so that edge is excised;
Step 150: the IMF film after die-cut is placed in to injection mold, and wherein said ink layer is towards the injection molding end of injection mold, and the then high rigidity plastics of injection moulding makes the paramount rigidity plastics product surface of IMF film bat printing in the time of injection moulding; Wherein, the bending modulus of this high rigidity plastics is greater than 8Gpa, and in the present embodiment, this high rigidity plastics can be PA or PPS.
