Disposable package molding method of electric heating film unit product

Abstract

The invention relates to a disposable package molding method of an electric heating film unit product. With a naked film, a pre-coated plastic film, silicon rubber, plastics, plastic-wood, resin and the like as materials, the electric heating film unit product is fabricated by a molding machine mold, and the disposable package molding method comprises the steps of: firstly cutting the naked film, connecting a conducting wire, then taking the plastic film, pre-coating an adhesive layer or refined silica gel on a single surface of the plastic film, and calendering a film; cutting the pre-coated film or silica gel film to form a cut film; wrapping the cut film provided with the pre-coated film or the silica gel film with the naked film from upper and lower surfaces, and finally putting multiple layers of films in the molding machine mold for forming under certain conditions. The electric heating film product provided by the invention is unitized and modular. In the electric heating film unit product provided by the invention is subjected to package molding at one time, and nearly all insulating and sealing materials can be used as the package naked film in the invention. The electric heating film unit product provided by the invention can be made into electric heating film products with various shapes.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a one-time packaging and molding method for finished products of electrothermal film units. Background technique [0002] With the development of material technology, as well as the requirements of environmental protection and energy saving, in recent years, inorganic non-metallic (carbon fiber based, printing ink carbon based, PTC based, etc.) electric heating films and polymer electric heating films have been greatly promoted in the heating field. Applications; especially the polymer electric heating film, because the material itself has superior properties such as no memory, no aging, no attenuation, arbitrary voltage, arbitrary power density, arbitrary shape, etc., in addition to a large number of applications in the heating field, it is also used in high-temperature health care environmental engineering, It has also been developed and applied in the field...

AI Technical Summary

Problems solved by technology

There are four technical problems in the application of existing electrothermal film products (rolled materials): (1) When planar electrothermal film products are applied to non-planar complex geometries, they generally adopt wrapping and splicing methods, which cannot achieve seamless and In close contact, the installation is labor-intensive, time-consuming, and material-intensive, and the quality cannot be guaranteed

Cutting ends, electrical contact parts, and wiring parts on the film cannot reach a high moisture-proof, waterproof, and insulation level, which is labor-intensive, time-consuming, and material-intensive, and the quality cannot be guaranteed

(3) When multiple units of electrothermal film products are assembled together, only external electrical connections can be made, and the electrical contact parts cannot reach a high level of moisture-proof, waterproof, and insulation. Installation, time-consuming, and material-consuming can not guarantee the quality

(4) The existing electrothermal film packaging process can only use plastic film, and the weather resistance, insulation level and physical properties of the plastic film have certain limitations, which cannot meet the application of some special occasions
