Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

According to the technical scheme, transparent PC or PMMA is generally selected as a substrate for a membrane substrate, a heating insert membrane is manufactured after the processing of wire distribution, high-pressure forming, hot bending and punching processes, the heating insert membrane is placed into an injection mold for insert injection molding, an obvious boundary line can be left between the heating insert membrane and a grid body, the attractiveness of a product is affected, and particularly in the production of transparent products, the boundary line is not easy to shield.

This technical scheme a concrete implementation mode of transparent heating grid of no trace, its concrete implementation mode is shown in fig. 1-2, including heating diaphragm 200, heater strip 300 and transparent grid body 100, heating diaphragm 200 in be provided with heater strip 300, the edge of heating diaphragm 200 one side is provided with the cambered surface structure that thickness is zero gradually, one side that heating diaphragm 200 set up the cambered surface imbeds transparent grid body 100, transparent grid body 100 forms the seamless laminating form with heating diaphragm 200.

During processing, according to the technical scheme, proper plastic particles are selected according to the requirements of customers and comprehensive factor analysis to be injected into the transparent grid body 100, wherein the plastic particles include but are not limited to PC and PMMA, and the heating film 200 is also made of transparent materials, including but not limited to PC and PMMA.

The heating wire 300 is embedded in the heating membrane 200 by a hot melting method, and then the plastic membrane with the heating wire is subjected to high pressure forming, hot bending and punching to manufacture the heating membrane 200.
