At a time when the construction industry is striding towards green and high quality, wood-plastic doors and windows, as innovative products, are rising strongly with their unique advantages. The wood-plastic co-extrusion equipment produced by Yongte Plastic Machinery can be called the core engine that promotes the vigorous development of the wood-plastic door and window industry.
Wood-plastic doors and windows have advantages that traditional doors and windows cannot achieve. In terms of environmental protection, with wood fiber (such as common sawdust and bamboo powder) and plastic (such as polyethylene PE and polypropylene PP) as the main raw materials, the production of 1,000 square meters of wood-plastic doors and windows can reduce the use of natural wood by about 300 cubic meters, greatly reducing the amount of deforestation and effectively protecting the ecological environment. No harmful gases such as formaldehyde are released during the production process, and the recycling rate of plastic components is as high as 80%, which is in line with the current circular economy and green production concepts.
In terms of performance, wood-plastic doors and windows perform excellently. Moisture-proof and anti-corrosion properties have been professionally tested. After being placed in a harsh environment with a relative humidity of 95% and a temperature of 35°C for 1,000 hours, the water absorption rate of the material is less than 3%, which is much lower than the 15%-20% water absorption rate of traditional wood. It effectively prevents wood decay and insect infestation, and can be used stably for a long time in a humid environment. After the material structure is optimized by Yongte's advanced technology of wood-plastic co-extrusion equipment, the product has a dimensional change rate of less than 0.5% after 100 cycles of temperature changes in the range of -40°C to 80°C. It has strong resistance to ultraviolet aging and its service life is 2-3 times longer than that of traditional wooden doors and windows. Wood-plastic doors and windows have both wood texture and plastic toughness, with a tensile strength of 30-40MPa, a bending strength of 40-50MPa, and an impact strength of 10-15kJ/㎡. They are beautiful, strong, and impact-resistant, providing reliable and safe protection for buildings.
In terms of appearance design, wood-plastic doors and windows are unique. With the help of Yongte Plastic Machinery, the natural wood texture can be accurately imitated, with a similarity of over 95%, presenting a realistic wood effect. Through the advanced color matching system, thousands of colors can be mixed according to design requirements to meet different architectural styles and consumer aesthetic needs.
Yongte Plastic Machinery's wood-plastic co-extrusion equipment is a solid guarantee for achieving these advantages of wood-plastic doors and windows. The equipment consists of precision components such as twin-screw extruders, single-screw co-extruders, co-extrusion systems, and molds. The screw diameter of the twin-screw extruder is usually in the range of 65-95mm, and the aspect ratio is 32:1-48:1. When the two intermeshing screws are running at high speed, based on the high shear mixing principle, they can generate a strong shear force of up to 500-800N・m, which can achieve uniform mixing and plasticization of 500-1000kg of wood-plastic raw materials at the micron level in a short time per hour, laying a solid foundation for the large-scale production of high-quality wood-plastic doors and windows. The single screw co-extruder is equipped with a high-precision metering pump, which can control the error of the co-extrusion raw material extrusion amount within ±0.5%, accurately control the co-extrusion raw material extrusion, and ensure perfect matching with the wood-plastic raw material. The co-extrusion system uses intelligent flow control technology to control the extrusion ratio and flow rate deviation of the raw materials within ±1%, ensuring that the two are ideally integrated when passing through the co-extrusion die. The co-extrusion die is made of special alloy steel, and after ultra-precision EDM and mirror polishing, the surface roughness Ra can reach below 0.4μm, ensuring that the surface of the extruded product is smooth and flat, and the dimensional accuracy is controlled within ±0.1mm.
The product is quickly cooled and shaped on the shaping table through an efficient circulating water cooling system, with a cooling rate of 5-10℃ per minute, which can effectively fix the shape and size of the product. Then, the high-precision double-crawler traction machine accurately pulls it to the cutting device at a stable speed of 0.5-3m/min, with a cutting accuracy of up to ±0.5mm. The entire production process is efficient and accurate, and the product qualification rate is as high as 98% or more, ensuring product quality stability and production efficiency. The equipment is also equipped with an intelligent control system. Operators can monitor and adjust the parameters of each production link in real time through a 10-inch high-definition touch screen. It is easy to operate, greatly reduces manual intervention, reduces labor intensity, and improves production efficiency and stability. At the same time, the key components of the equipment adopt a modular design, which is convenient for quick disassembly, installation and maintenance, greatly shortening the equipment maintenance time, reducing maintenance costs and downtime, and providing strong support for the company's continuous production.
From the perspective of market prospects, wood-plastic doors and windows are ushering in unprecedented development opportunities. With the improvement of global environmental awareness and the increasingly stringent requirements of the construction industry for energy conservation and emission reduction and improving building quality, the market demand for wood-plastic doors and windows as environmentally friendly and high-performance building materials continues to grow. In China, the promotion of new urbanization construction and the large-scale energy-saving transformation of existing buildings provide a broad market space for wood-plastic doors and windows. In the international market, Europe, the United States, Asia-Pacific and other regions favor green building materials. In recent years, my country's export volume of wood-plastic doors and windows has increased year by year, with an annual growth rate of 15%-20%.
According to the prediction of relevant market research institutions, the global WPC door and window market will continue to expand at an average annual growth rate of 12%-18% in the next five years, and WPC doors and windows are expected to occupy a larger market share in the field of building doors and windows.
The WPC co-extrusion equipment produced by Yongte Plastic Machinery, with advanced production technology, helps WPC doors and windows to play multiple advantages such as environmental protection, excellent performance, and beautiful appearance. With the booming market prospects, it will surely push the WPC door and window industry to a new height and contribute more to the green transformation of the construction industry.
