Embodiment Construction

[0029] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0030] ginseng figure 2 Shown, a kind of plastic plate of the present invention specifically comprises:

[0031] The foamed plastic layer 20 has a number of air bubbles inside, and the foamed plastic layer is injection molded from a foamable plastic material;

[0032] The appearance skin layer 24 is naturally covered on at least one of the upper surface and the lower surface of the foamed plastic layer, and the appearance skin layer is co-injected with the foamed plastic layer by resin through a double-material co-injection molding machine. Preferably, an appearance skin layer may be provided on both the upper surface and the lower surface.

Abstract

The invention discloses a plastic flat plate and a manufacturing method thereof. The plastic flat plate comprises a foamed plastic layer and an appearance skin layer; a plurality of bubbles exist inside the foamed plastic layer, and the foamed plastic layer is formed through injection molding with a foamed plastic material; the appearance skin layer naturally covers at least one of the upper surface and the lower surface of the foamed plastic layer and is formed through injection molding together with the foamed plastic layer with resin by a dual-material co-injection molding machine. The method has the advantages that the trouble of secondary processing that a wood-grain appearance skin is required to be pasted additionally at present can be saved, so that the processing procedure can be simplified, and the use of plastic that replaces wood can be improved effectively, so that the requirements on ecological environmental protection can be met.

Description

Technical field [0001] The invention involves the field of plastic products technology, especially a plastic tablet and its production method. Background technique [0002] Plastic materials have been widely used for molding, and they have the advantages of low cost and easier processing processes. However, because the plastic materials itself is highly contracted, it is difficult to achieve for products that need high intensity. Generally, it is difficult to achieve. Generally, it is difficult to achieve. GenerallyThe design is to strengthen the intensity with thickness, which will not only increase the amount and volume of the material, but also the effect of plastic materials in terms of shockproof or sound insulation is inferior. It is even more difficult to apply in the shells such as speakers or speakers, so one is one.The technology that uses the foam plastic material to form formed was immediately developed, and the air bubbles inside it to achieve sound insulation or sho...
