imo surface nano grain forming process

Abstract

An IMO surface nano-grain molding process, firstly use silk screen or UV texture technology to prepare a semi-finished product with replaceable material layer, ink layer and UV texture layer; place it in the molding mold for hot pressing molding; start the intelligent partition heating device, At the same time, press the semi-finished product on the forming regular water flow mold through the medium-pressure gas filling and medium-pressure pumping operations to obtain the thermoformed semi-finished product; at this time, the thermoformed semi-finished product has curved corners and concave curved surfaces. And the curved corner also has an extension section; after the heat-pressed semi-finished product is cooled, it is removed from the forming timing water flow mold, and the extension section is removed by laser cutting or CNC cutting to obtain a panel with nano-grain; the panel with nano-grain Placed in the mold, injecting plastic particles on the exposed surface where the replaceable material layer of the nano-grained panel is integrally formed into an injection molded product. It has the advantages of direct injection molding with plastic particles, no need for adhesives, and no need for multiple mold openings.

Description

technical field [0001] The present application relates to the technical field of micro-grain formation, in particular to a nano-micro-grain formation process on the surface of IMO. Background technique [0002] At present, with people's dependence on electronic products and diversified needs, the requirements for electronic product panels are becoming more and more sophisticated and complex; at present, the appearance of electronic products is mainly realized through molds; the etched molds are about to pass through The adhesive is coated with the substrate for roller coating to realize the transfer of the mold texture; the obtained decorative board is then bonded and coated with the electronic product through the adhesive. [0003] The basic combination process of traditional decorative boards and electronic products, because its structure is formed by adding adhesives on the back of the texture layer, and then bonding the electronic products through the adhesives; It is a...

Problems solved by technology

[0003] The basic combination process of traditional decorative boards and electronic products, because its structure is formed by adding adhesives on the back of the texture layer, and then bonding the electronic products through the adhesives; It is an adhesive, which is easy to age during the use of the adhesive, causing peeling or falling off between the texture layer and the electronic product; secondly, what is even more insufficient is that due to the need to inject the adhesive through pressure during the use of the adhesive, the texture Under the action of high pressure between the layer and the electronic product, it is easy to damage the texture due to the pressure. The texture is deformed or pulled by stamping, which affects the rendering effect of the texture.

[0004] If you want to obtain the panel of injection-molded electronic products, if the panel requires texture, graphics, background color, etc., you need to go through at least two in-mold injection molding and mold opening to achieve it. For example, the texture of the display panel of a car, It is often necessary to inject the transparent matrix first, and then inject the black material, which can be completed by two times of heating and injection molding; this method will lead to the imbalance of material expansion and contraction due to the two injection moldings, which will affect the effect of texture rendering, and secondly, it will also lead to the process Complicated, easy to increase production cycle and cost

[0005] In addition, the traditional multi-injection process also easily leads to inconsistent product shrinkage ratio due to the difference in the properties of the texture layer and the injection particle material during the thermal injection molding process, resulting in uneven texture layers, thus affecting the appearance of the texture layer Effect
