Description
Technical field
The present invention relates to a kind of preparation method of leg of spectacles, more particularly, relate to a kind of injection molding forming method of the two-color spectacles leg that contains metal finishing sheet.
Background technology
Glasses are being brought into play more and more important effect in people's sphere of life, and in our daily life, glasses are the necessity of protection eyes, are again a kind of ornaments of beauty treatment; Leg of spectacles is as an important component part of glasses, especially along with the development of glasses jewellery, fashion, color is beautiful and the elegant major criterion that has become numerous young men to pursue of profile, and when pursuing comfort level, people are also more and more higher to its requirement attractive in appearance.
At present, the leg of spectacles of the embedded contact pin form of domestic production mainly contains following several method:
(1) plastic cement is played copper core
First the method will take copper-nickel alloy and make simple and be similar to the contact pin of straight line as raw material, and then contact pin is squeezed in acetic acid colloid, the defect of this method is that the shape of contact pin can not have a greater change, otherwise will squeeze in acetic acid colloid, although or can squeeze into and in colloid, there will be eccentric phenomena; And in actual operating process, gold or the silver color of the contact pin that copper-nickel alloy used is made at the bottom of only can chromium plating/nickel plating, adds that other pigment can be because at high temperature fading with colloid friction;
(2) sheet material pressing
This production method is mainly to form by contact pin being put into sheet material pressing, and color and style all seem extremely dull comparatively speaking, not abundant.
(3) contact pin cover gum cover
This production method is on ready-made contact pin, to put the gum cover of moulding, this mode of operation trouble relatively in actual operation, and also shape can not vary widely, and makes style more single.
Although above several method can be produced leg of spectacles, leg of spectacles shape and the color produced are all more single, and the quite trouble that operates also.
