The integrated molding process eliminates assembly defects associated with multi-layer materials and reduces production costs.

[0033] PC / PMMA / ASA plastic alloy is a composite material formed by blending polycarbonate (PC), polymethyl methacrylate (PMMA), and acrylonitrile-butadiene-styrene (ASA). It combines the advantages of each material, such as the heat and weather resistance, dimensional stability, and impact resistance of PC resin, with the processing fluidity of ABS resin. PMMA provides high transparency and gloss, giving the PC / PMMA / ASA alloy excellent optical properties. The addition of ASA improves the material's weather resistance, making it resistant to the effects of UV rays and climate change, making it suitable for outdoor use. The high toughness and impact strength of PC enhance the alloy's impact resistance, and PC's heat resistance enables the plastic alloy to maintain its performance even at higher temperatures. The addition of PMMA increases the alloy's surface hardness, giving it excellent scratch resistance. The PC / PMMA / ASA plastic alloy also exhibits good chemical resistance, making it resistant to corrosion from some chemicals, acids, and alkalis. This embodiment uses PC / PMMA / ASA plastic alloy to form an integral plastic alloy panel 1, which has heat resistance, weather resistance and impact resistance. Only a single-layer plastic alloy panel 1 can achieve the hardness and processing requirements achieved by multi-layer composite materials of stainless steel, ABS, acrylic and galvanized sheet in the existing technology, and can be directly fixed to the back panel 2 through the box connection structure 4, thereby optimizing the installation structure and overcoming the complex assembly problem caused by the original production and assembly defects.
