(Quality control inspection area)
01:Strictly select materials to control the quality from the source
We strive for excellence in the selection of raw materials, and incoming material inspection is the first checkpoint for our strict quality control!
Taking aluminum profiles as an example, their bending degree, thickness, surface quality, etc. all need to undergo strict inspection. The bending degree shall not exceed 1mm, the thickness error Control shall be within 0.15mm, and the surface shall not have obvious mechanical patterns or shadows. In addition, there are detailed standards for the spraying quality, coating thickness, adhesion, etc. of aluminum profiles to ensure that each aluminum profile meets high-quality requirements.
As an important component of doors and windows, the quality of hardware directly affects the service life and safety of doors and windows. Our hardware inspection standards cover various aspects such as thickness, size, appearance, and functionality, ensuring that each hardware is sturdy, durable, exquisite in appearance, and functional. For example, the thickness error of the hinge Control is within ±0.2mm, and the appearance is free of cracks, burrs, and other defects.
The inspection of auxiliary materials and glass is also strict, and the color, fit, and cross-sectional size error of the sealing strip must meet high standards. The glass should be smooth and flat, consistent in color, without obvious dents, bumps, Proteus and other defects.
Our strict control over each material ensures the excellent quality of our products from the source.
02:Strive for excellence,process inspection ensures every detail
In the production process, we are also not slacking off. Each link, such as threading, cutting, machining, assembly, debugging, gluing, packaging, and storage, has detailed inspection standards and methods. For example, in the process, the type, size, color, and quantity of the material must be consistent with the process order, the film must be flat without bubbles, and the tooth depth Control must be between 0.3-0.6mm. In the cutting process, the angle and size of the material must be accurate, with a tolerance value of 45 degrees Control within ± 0.3 degrees.
Assembling process is perfect, the error of length and width Control is within ±1mm, and the flatness of the splicing angle is 0.2mm, ensuring the beauty and sealing of doors and windows. During the debugging process, we implement 100% inspection, strictly checking the opening direction of doors and windows, lock height, and installation of hardware accessories to ensure that every detail meets the process requirements. During the gluing process, there are clear standards for the color, surface flatness, and absence of impurities and bubbles of glass glue to ensure the waterproof and sealing performance of doors and windows.
03:Complete product inspection full-range guarantee product
The finished product inspection is the last checkpoint to ensure product quality.
Our finished product inspection standards cover major items and general inspection items to ensure that every door and window meets high-quality requirements. For example, the component Lyne must be firm, free of missing parts, and not loose; The opening and closing of the fan is smooth, without abnormal noise or falling; The accessories are installed and matched, in the correct position, and the tightness is moderate.
The inspection of the size of doors and windows is also strict, height, width, and inner dimensions of the structureThe error of Control is within a very small range, ensuring the precise installation and aesthetic effect of doors and windows. For example, the error of door and window height and width Control is within ±1mm, and the difference of opposite dimensions Control is within ±1.5mm. These strict standards ensure that every door and window is perfect.
