Problems solved by technology

If the surface is to achieve a high-gloss effect, the varnish layer needs a thicker film thickness; but if the varnish layer is too thick, the parts will sag on the edge of the parts during the drying process after painting. To avoid sagging, it is necessary to Reduce the film thickness of the varnish layer, which does not meet the high standard requirements of high gloss
[0004] At the same time, in the process of painting, the volatilization of paint will cause certain harm to the environment.
During the spraying process of plastic parts, due to the non-recyclable thermosetting paint, there is a coating that cannot be easily peeled off, which eventually leads to difficulties in the recycling of the parts, which in turn creates obstacles for the recycling of automotive plastic parts
Moreover, due to the complexity of the painting process, it is necessary to increase the basic links such as pretreatment, coating, and transportation. Part of the painting process also requires multiple production processes such as primers, topcoats, and UV curing paints, as well as the resulting pass rate problems, making the entire Double or even triple the cost of parts

Embodiment Construction

[0024] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0025] In the manufacturing method of the high-gloss D-pillar decorative panel, the D-pillar decorative panel is made by a high-gloss seamless injection molding process. The high-gloss seamless injection molding process uses 180°C superheated water to rapidly heat up the surface of the mold (the high-gloss surface needs to be mirror-polished), so that the surface temperature of the molding cavity reaches above the glass transition temperature (Tg–Glass Transition Temperature) of the resin plastic, and then Started injection molding. When the mold cavity filling process is completed, the treated water is used as the cooling medium to make the surface temperature of the mold drop rapidly; thereby changing the surface characteristics of the plastic product, eliminating the weld lines, weld mar...

Abstract

The invention discloses a production method of a highlight D post decorative sheet. The D post decorative sheet is made by a highlight traceless shooting technique; according to the production method of the highlight D post decorative sheet, the highlight effect can be realized without the spraying on a highlight part after the D post decorative sheet is made by the highlight traceless shooting technique; under the precondition of effect guarantee, the cost can be reduced effectively, the delivery time can be shortened, and the environment pollution can be reduced.

Description

technical field [0001] The invention relates to an automobile exterior trim, in particular to a method for manufacturing a high-gloss D-pillar decorative panel. Background technique [0002] In recent years, as young people have gradually become the main force of car purchases, car design styles have gradually changed. OEM designers have introduced some innovative elements to win the favor of young people, such as using high-gloss D-pillar decorative panels to replace the rear door glass. It is consistent with the side door glass, which can bring a good visual transition. As appearance has become the first choice for more and more users to buy cars, the high-gloss design of exterior decoration has become a trend and is favored by more styling designers. Naturally, high-gloss parts have gradually become a selling point. The related manufacturing process, Structural design and material technology have naturally become the new focus of attention in the field of automotive engi...
