Abstract
The invention discloses a method and a device for manufacturing a mobile phone shell. The method comprises the step of A, grinding a metal material into powder; B, heating a polycarbonate raw material to form a fluid, adding the powdery metal material and pigments into the polycarbonate raw material and mixing fully, wherein the weight proportion of the metal material to the polycarbonate raw material is 1:4-6; C, injecting the mixed material into a mould, taking the mixed material out after the mixed material is cooled so as to obtain a mobile phone shell blank; and D, polishing the outer surface of the mobile phone shell blank to obtain a mobile phone shell finished product. According to the mobile phone shell manufactured by the abovementioned method, the metal powder in the material enables the polished mobile phone shell to be able to give out metal luster and own a metal texture. Meanwhile, the plasticity of the polycarbonate in the material enables the mobile phone shell to be relatively soft, so that the mobile phone shell can attract impact efficiently, thereby protecting internal parts of a mobile phone. In addition, as the internal and external materials of the mobile phone shell manufactured by the abovementioned method are consistent, the abrasion mark is not obvious, and the impression is not affected.
Description
Technical field
The present invention relates to the manufacturing technology of mobile phone shell, specifically, be manufacture method and the manufacture equipment of a kind of mobile phone shell.
Background technology
Since mobile phone is born, its outward appearance just has status of equal importance with function own.In the function machine epoch, owing to mobile phone has the small screen and input through keyboard, its outward appearance can be designed to various form, and therefore the outward appearance of mobile phone presents variation.And popularizing along with smart mobile phone, because smart mobile phone uses touch screen input, screen occupies most spaces in mobile phone front, and the changeability of cell phone appearance is greatly reduced, and the homogeneity of cell phone appearance is increasingly severe.And generally in the material of mobile phone shell, done article in numerous factory.The mobile phone shell material of smart mobile phone can be generally divided into metal material and two kinds of plastics.Strength of Metallic Materials is high, the good mid-to high-end product by most manufacturers of texture uses.But the mobile phone shell of metal material is big due to rigidity, when mobile phone is impacted, impulsive force directly passes to the parts of interior of mobile phone, it is impossible to play the effect of buffering.And metal-back is in order to realize more preferable perception, need at top layer plating or paint colors, but when mobile phone shell is worn, the plating on top layer or color are damaged, expose metal bottom, largely effect on perception on the contrary.The Merlon that the mobile phone shell of plastic material is used with the mobile phone of Lumia brand is as representative, and makrolon material can be made by recycled plastic, beneficially environmental protection.The Lumia of such as black
The shell of 1520 mobile phones i.e. makes of waste disk.It addition, the mobile phone shell of makrolon material can easily join color, and color is beautiful, it is internal that this color gos deep into whole mobile phone shell, even if mobile phone shell is worn, does not also have the situation that color is inconsistent, in the whole life cycle of mobile phone, its outward appearance will not occur big change.But, the mobile phone shell of makrolon material does not has the texture of metal, it is impossible to meet some consumers's aesthetic requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide manufacture method and the manufacture equipment of the mobile phone shell of a kind of makrolon material that can produce metal-like.
In order to solve above-mentioned technical problem, the invention provides the manufacture method of a kind of mobile phone shell, including:
A, metal material is ground to form powdery；
B, polycarbonate starting material being thermally formed flow-like, metal material and the pigment of powdery are added in polycarbonate starting material and is sufficiently stirred for, wherein said metal material is 1:4-6 with the part by weight of polycarbonate starting material；
C, will stirring after material inject mould, take out after cooling, obtain mobile phone shell blank；
D, outer surface to described mobile phone shell blank are polished, and obtain mobile phone shell finished product.
Further, in described step A, metal material is ground to form the powder that particle diameter is 1-3 micron.
Further, in described step B, metal material is 1:5 with the part by weight of polycarbonate starting material.
Further, in described step C, while the material after stirring is injected mould, outside mould, spray cold air.
Further, the temperature of described cold air is 5-10 degree Celsius.
Further in, in described step C, the outside of the mobile phone shell of mould downward, makes described mold vibration being injected while mould by the material after stirring.
Further, described metal material is stainless steel.
Present invention also offers the manufacture equipment of a kind of mobile phone shell, including:
Grinder, for grinding to form powdery by metal material；
Heater, for being thermally formed flow-like by polycarbonate starting material；
Mixer, stirs after described metal material and polycarbonate starting material being mixed；
Injection machine, for the material after stirring is injected mould, takes out after cooling, obtains mobile phone shell blank；
Polishing machine, for being polished mobile phone shell blank, obtains mobile phone shell finished product.
Further, described injection machine is configured with hair-dryer, while the material after stirring being injected mould at injection machine, outside mould, sprays cold air.
Further, described mould is additionally provided with bobbing machine, for making described mould vibrate when injection.
By the mobile phone shell manufactured by the present invention, the metal dust in material makes mobile phone shell can send the gloss of metal after a polish, has the texture of metal.The plasticity of the Merlon in material makes mobile phone shell relatively soft simultaneously, can effectively attract to clash into, thus protect interior of mobile phone parts.Further, since the mobile phone shell interior exterior materials that the present invention produces is consistent, vestige is inconspicuous upon wear, does not affect perception.
Accompanying drawing explanation
Fig. 1 is the flow chart of the manufacture method of the mobile phone shell of the present invention.
Fig. 2 is the theory diagram manufacturing equipment of the mobile phone shell of the present invention.
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art may be better understood the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As it is shown in figure 1, the manufacture method of the mobile phone shell of the present invention, including:
Step 101, metal material is ground to form powdery；
Step 102, polycarbonate starting material being thermally formed flow-like, metal material and the pigment of powdery are added in polycarbonate starting material and is sufficiently stirred for, wherein said metal material is 1:4-6 with the part by weight of polycarbonate starting material；
Step 103, will stirring after material inject mould, take out after cooling, obtain mobile phone shell blank；
Step 104, outer surface to described mobile phone shell blank are polished, and obtain mobile phone shell finished product.
