Embodiment Construction

[0010] The present invention includes PC glue raw material, vulcanizing agent, silicone oil and pearl powder, and is characterized in that: the percentage examples are: PC glue raw material 50%-65%, vulcanizing agent 1%-4%, silicone oil 5%-8%, pearl powder 10% %-35%.

[0011] A processing method of a TPU pearlescent three-dimensional molding process formula for an electronic product shell, the steps are as follows:

[0012] (1) Put the raw material of PC rubber, vulcanizing agent, silicone oil and pearl powder into the mixer and stir evenly for 20-30 minutes to ensure complete fusion. The above ingredients can make the shell piece have good softness.

[0013] (2) Inject the fused ingredients into the mold for molding, the molding temperature is 180-220℃, the injection pressure is controlled at 20-120Mpa, and then baked at 120℃ for 3-4 hours, the appearance has a strong three-dimensional effect and texture. Diversified choices.

[0014] (3) Using the polishing treatment meth...

Abstract

The invention relates to the technical field of electronic product shell body production, and particularly to an electronic product outer shell TPU pearl stereo-molding process. The process comprises the steps: putting a PC plastic raw material, a vulcanizing agent, silicone oil and a pearl powder into an internal mixer, and stirring uniformly for 20-30 minutes to ensure complete fusion; carrying out injection molding of the fusion ingredients, injecting into a mold and molding with the molding temperature of 180-220 DEG C, controlling the injection molding pressure of 20-120 MPa, baking at the temperature of 120 DEG C for 3-4 hours; and adopting a polishing treatment mode, and carrying out polishing treatment of molded shell body flaws and pouring gate burrs which are hard to cut. The shell part softness is good, the appearance stereo feeling is strong, diversifying selection of lines can be achieved, the surface has no need of post processing, moreover, the production process is simple, and the production cost is low.

Description

Technical field: [0001] The invention relates to the technical field of electronic product casings, in particular to a TPU pearlescent three-dimensional molding process for electronic product casings. Background technique: [0002] In the production and processing of electronic product casings, such as the casings of mobile phones and handheld computers, the patterns of electronic products are printed on the casings or glued to the casings. Such casings do not feel good, and at the same time, the production process is complicated and the production cost is high. Invention content: [0003] The purpose of the present invention is to aim at the deficiencies of the prior art, and to provide a TPU pearlescent three-dimensional molding process for the shell of electronic products, the shell has good softness, strong three-dimensional appearance, diversified selection of lines, no post-processing on the surface, and at the same time The production process is simple and the produ...
