Aluminum plastic composite doors and windows is a new type of doors and windows after aluminum alloy doors and windows and plastic steel doors and windows. It is an upgraded product of aluminum plastic aluminum (bridge cutoff aluminum) doors and windows. The aluminum-plastic composite doors and windows are made of aluminum-plastic composite profiles and hollow glass, with multi cavity structure and beautiful appearance, and have the functions of energy saving, sound insulation, noise prevention, dust prevention and waterproof. The K value of the thermal conductivity coefficient of this kind of doors and windows is 2.0-2.8w/m2 · K, which reduces the heat loss by half compared with ordinary doors and windows, reduces the heating cost by about 30%, and the sound insulation is more than 29 dB. The water tightness and air tightness are good, both of which meet the national class A1 window standard.
The principle of the aluminum-plastic composite window profile is to divide a profile into two parts, plastic and aluminum alloy, which are designed and produced separately. The outer aluminum and inner plastic are pressed together by rolling and embedding to make it an inseparable whole, making full use of the advantages of the plastic profile (1250 times higher than the aluminum profile) with good energy-saving effect and high strength of the aluminum alloy profile. The thermal insulation of doors and windows made of this composite profile is at the same level as that of plastic (steel) windows - the national standard level, which completely solves the fatal problem of aluminum alloy's fast conduction and heat dissipation and does not meet the energy-saving requirements. At the same time, some new structural coordination forms are adopted to completely solve the old and difficult problem of "lax sealing of aluminum alloy sliding windows". This innovative structural design takes into account the advantages of plastic and aluminum alloy materials, and meets various requirements for decorative effect, strength and aging resistance of doors and windows. The groove structure design of the aluminum-plastic composite door and window profile and the sealing mode of the frame and leaf overlap are the same as those of the plastic profile, so it has the air tightness and water tightness close to that of the plastic window.

Chuanyuan aluminum-plastic composite door and window profile combines the respective advantages of plastic profile and aluminum alloy profile, gives full play to the advantages of plastic profile in energy saving, sound insulation and high strength of aluminum alloy, and can design and manufacture high-grade doors and windows with heat preservation, heat insulation, beauty and durability.
1. Energy saving and good thermal insulation performance
The thermal conductivity of aluminum-plastic composite profile is about 1/872 of that of aluminum, which is close to that of plastic profile.
2. Sound insulatio
The sound insulation of doors and windows made of aluminum-plastic profiles can reach 30-37db, meeting relevant regulations. Plastic aluminum doors and windows with a distance of 3 meters can achieve the effect of aluminum alloy doors and windows with a distance of 10 meters.
3. Good fire resistance
The aluminum alloy part does not burn, and the plastic part does not support combustion
4. Impact resistance
The surface of aluminum-plastic profile is made of aluminum alloy. Due to its high strength, its hardness is better than that of plastic steel profile.
5. High anti-theft performance
The hollow glass with aluminum alloy decorative strip is not only beautiful, but also has the function of protective fence.
6. Flexible and convenient assembly and cost reduction
Doors and windows made of aluminum-plastic profiles can be spliced. Plastic parts can be welded and spliced. With corner splicing (aluminum and plastic), the corner strength is higher and more firm.
7. Good decorative effect
The surface of aluminum-plastic profile can be sprayed and roller coated with various color paints, which can be processed into various imitation wood grain and two-color bottom effect
8. Widely used and practical
All kinds of high and low floor doors and windows can be used. It is a modern building door and window product.
9. High quality and low price
Compared with the bridge broken aluminum alloy doors and windows, the aluminum-plastic composite doors and windows have better energy-saving and sound insulation effects. The sprayed profiles can save 60-80 yuan per square meter, and the wood grain and electrophoresis profiles can save 100-200 yuan per square meter, truly achieving high quality and low price.

Sichuan Chuanyuan Plastic Co., Ltd. is the first enterprise in Sichuan Province and even the southwest region to produce "Chuanhuai" brand energy-saving aluminum-plastic composite profiles. Sichuan Chuanyuan Plastic Co., Ltd. is a PVC plastic door and window manufacturer integrating production and installation. Founded in 2000, it has a group of engineering and technical personnel with rich production experience. The "Chuanyuan", "Chuanhuai" and "Chuanjiang" colored plastic steel profiles produced by the enterprise sell well both inside and outside the province. After several years of continuous innovation, the "Chuanhuai" brand aluminum-plastic composite profile developed and produced is a combination of the advantages of high strength of aluminum alloy and good energy-saving effect of plastic steel profile. It is an upgraded product of aluminum alloy doors and windows and plastic steel doors and windows. It has passed the national ys/t729-2010 profile standard and gb/t29734.2-2013 national quality inspection center for aluminum-plastic composite doors and windows and obtained a certificate of conformity. In order to meet the modern people's pursuit of fashion and high-quality life, the enterprise summarizes the advantages and disadvantages of various color profile production processes at home and abroad, makes continuous improvement and innovation, takes colored extrusion as the background color, adopts roller coating, transfer printing, full body, printing and other processes, produces various wood grains according to the different needs of users, and then uses various high-grade plastic paint, fluorocarbon UV paint and other spraying, roller coating and printing. The high-grade and environment-friendly colored plastic steel and aluminum-plastic composite profiles produced are beautiful, elegant and rich in color lines, bringing people a warm feeling of returning to nature. In line with the business philosophy of honesty, trustworthiness, pioneering and enterprising, and the enterprise spirit of unity, diligence, realism and innovation, the company welcomes new and old users from all walks of life to patronize and negotiate, and create a "win-win" situation
