Product Quality
Material Selection
Excellent Factories: They are capable of screening suppliers. Since different suppliers offer materials at different prices, it’s necessary to compare offers from various merchants to determine the price and quality differences, and then cooperate with those suppliers who offer high cost-performance materials. They will choose products whose materials meet the standards in terms of hardness, strength and sealing performance. Besides, materials of different qualities have different functions, so they will select products that meet customers’ needs.
Average Factories: In order to reduce costs, average factories may purchase some relatively cheap materials to make door and window frames. These inferior aluminum alloys are prone to bending and damage during later use. Especially after being exposed to the elements, the aluminum alloys are more vulnerable, which accelerates the process of damage.
Production Technology
Excellent Factories: They possess advanced cutting techniques and can be more precise in the cutting, assembling and welding of aluminum alloy frames, with more complete cutting. In terms of the later spraying process on aluminum alloys, only by applying a layer of spray can an oxide film be formed on the surface to isolate the aluminum alloy from the outside air, thus prolonging its service life.
Average Factories: The equipment is ordinary, so the products processed are of poor quality. Given the low quality of the purchased materials, the quality of the processed products is substandard. The technology is average, and the processes of joining, splicing and assembling aluminum alloys are not fine enough. During the later installation process, it is very likely that the interfaces of the aluminum alloy window frames are too large or too small. These are the problems that may occur in average factories due to their poor cutting techniques for aluminum alloy doors and windows.
Product Design
Style Diversity
Excellent Factories: Excellent factories are more likely to pursue innovation and design distinctive doors and windows. For example, they use some environmentally friendly materials. In recent years, people have preferred environmentally friendly materials because they have a longer service life, are of better quality and cheaper, and the materials of door and window frames are of good quality. This is the kind of doors and windows that people are choosing now. In terms of the style of doors and windows, the design is more innovative, meeting customers’ personalized pursuit of doors and windows.
Average Factories: The designs of average door and window factories are relatively simple. There is a limited selection in the design of doors and windows, the color and texture of glass, etc., and the styles of customized doors and windows for customers are also very limited. Since the door and window designs are from average factories, the shapes of doors and windows are very simple, offering customers few options.
Customization Service
Excellent Factories: They can provide high-quality customization services and carry out personalized customization according to the special dimensions, shapes and functional requirements provided by customers. For example, for the door and window requirements of some special-shaped buildings, excellent factories can provide customized door and window solutions for customers through accurate measurement and advanced manufacturing techniques. And during the customization process, they will maintain good communication with customers to ensure that the final product meets customers’ expectations.
Average Factories: The customization service capacity of average factories may be limited. They may not be able to meet some orders with non-standard sizes or special functional requirements well, or problems may easily occur during the customization process, such as inaccurate sizes of customized doors and windows and imperfect function realization.
Quality Inspection
Inspection Items and Standards
Excellent Factories: They have a complete quality inspection system covering all aspects of door and window production. From the inspection of raw materials entering the factory, to the spot check of semi-finished products, and then to the full inspection of finished products, the inspection items are comprehensive. For example, they will test the physical performance indicators of doors and windows, such as airtightness, water tightness and wind pressure resistance, and the inspection standards are strict, usually in accordance with national standards or even higher corporate standards. Taking the airtightness test as an example, the doors and windows produced by excellent factories can meet the highest national level standards, effectively preventing air leakage and improving indoor comfort and energy-saving effects.
Average Factories: The quality inspection process in average factories may be relatively weak. The inspection items may be incomplete, and the inspection of some key performance indicators is not taken seriously enough or the inspection methods are not scientific enough. For example, they may only simply check the appearance and basic dimensions of doors and windows, ignoring the strict testing of their physical properties. This leads to some substandard doors and windows entering the market, posing potential risks in use for consumers.
Testing Equipment and Personnel
Excellent Factories: They are equipped with advanced testing equipment, such as high-precision airtightness testers, water tightness testing equipment, wind pressure resistance testing machines, etc. And there are professional quality inspection personnel who have received strict training and are familiar with various testing standards and operating procedures. They can accurately operate the testing equipment and scientifically analyze the test data, thus ensuring the reliability of door and window quality.
