Manufacturing method for anti-falling light TPU protective sleeve

Abstract

The invention discloses a manufacturing method for an anti-falling light TPU protective sleeve. The anti-falling light TPU protective sleeve is high in grade and resistant to falling, and can be purchased and favored in a wider range. The manufacturing method for the anti-falling light TPU protective sleeve comprises the following steps that 1, PU leather is punched according to the shape of the protective sleeve; 2, the punched PU leather is placed into an injection mold; 3, the mold is closed for injection molding, a TPU material is subjected to high-temperature pressurization in a gun barrel of an injection molding machine through the injection molding machine, so that bubbles are generated in the TPU material, and then the TPU material which generates the bubbles is injected into the injection mold through a screw rod and then is cooled and molded; and 4, mold is opened to obtain a finished product.

Description

technical field [0001] The invention relates to a method for manufacturing a protective case, in particular to a method for manufacturing a protective case for mobile phones and tablet computers. Background technique [0002] The usage rate of digital products such as mobile phones and tablet computers is very high. Equipping these digital products with protective cases can protect the product itself well and prevent damage such as friction and falling; [0003] In the prior art, in order to achieve soft protection ability, soft TPU is used to make it. The shock absorption and anti-collision ability of soft TPU is only improved compared with hard plastic shells, but the effect is still limited; and the soft TPU The hand feel is poor, the grade is low, and the structure is very simple, which leads to more high-end and more diverse protective covers made of other materials, although other materials are heavier and have poorer anti-collision effects. [0004] With the advent o...

[0003] In the prior art, in order to achieve soft protection ability, soft TPU is used to make it. The shock absorption and anti-collision ability of soft TPU is only improved compared with hard plastic shells, but the effect is still limited; and the soft TPU The hand feel is poor, the grade is low, and the structure is very simple, which leads to more grades and diversity. Protective cases made of other materials are still popular, although other materials are heavier and have poorer anti-collision effects.
