Due to can closely be combined using the hard portions and soft section of " quadric injection mould mechanography ", eyeglass frame structure, gap is not formed between the two, jog is not also formed, thus do not result in the problem of clamping hair and injured skin.
Selected hard material and soft material will not discharge harmful material.In addition, material therefor has splendid stability, thus when temperature is subzero 10 degree to 70 degree, will not deform, phenomenon of rupture;When eyeglass wearer is perspired, it is difficult to be influenceed by the sweat of people and produces physical change, deformation or be lost;It is difficult to be affected by temperature, ' therefore directly injury will not be caused to user(Scald, frostbite), it is applicable to various weather conditions(Heat, severe winter).
Selected material have it is various do color effect, can make transparent, translucent or colored etc., be further adapted for printing various patterns or word.
Further, the surface of whole eyeglass frame structure does not have metal fittings, is difficult to damage skin.The eyeglass frame structure is all made of elastomeric material, therefore is not in sharp otch when raw material is truncated, and security is very high.
Further, due to using injection molding, eyeglass frame structure of the invention is convertible variously-shaped, and it can subtly produce word or pattern with concave-convex effect.
Finally, due to using injection molding, production loss can be reduced, simplify post-processing process, the production time is saved.
By the description below in conjunction with each accompanying drawing to preferred embodiment, the object of the invention, feature and advantage can be more clearly understood that.Brief Description Of Drawings
