Hardcover Residential Project: Efficient Practice with 60% Shorter Construction Period for 1,000 Housing Units

Project Background

A high-end hardcover residential project of a first-tier real estate enterprise in the city plans to build 12 high-rise residential buildings with a total of 1,500 housing units, covering a variety of door types such as wooden doors and aluminum alloy kitchen and bathroom doors. Traditional damper hinges were originally planned for construction. The initial project calculation found that the installation and debugging of traditional hinges for a single door takes more than 15 minutes, and problems such as unsmooth opening and closing and uneven door-closing force are prone to occur due to differences in workers' operations, with a rework rate of about 12%, which not only affects the overall construction period but also increases labor and material losses. To ensure the on-time delivery of the project and reduce construction costs, the project party finally chose to cooperate with WEINI and adopted 18.5mm Pin-Pull No-Adjust Split Damper Hinges for all projects.

Value of WEINI Hinges in Project Implementation

Leap-forward improvement in installation efficiency: Adopting a pin-pull and no-adjust design that can be activated immediately, WEINI hinges can be installed in three steps, and the construction time for a single door is shortened to less than 5 minutes. The installation of door and window hinges for 1,500 housing units, which originally required 20 workers to construct for 15 days, was finally completed by only 10 workers in 6 days. The overall construction period was shortened by 60%, and the labor cost was directly reduced by 50%.
Zero rework for unified quality: The product does not require complex debugging, eliminating installation problems caused by differences in manual operations. The rework rate of hinge installation throughout the project is 0, and all doors achieve smooth opening and closing as well as silent buffering effects. The satisfaction rate of owners with the use experience of doors and windows during the delivery phase reaches more than 98%.
High compatibility between appearance and decoration style: The hardcover styles of the project cover various types such as modern minimalism and light luxury Nordic style. WEINI hinges provide four color schemes including light luxury gold and shining silver, which can be flexibly matched according to the decoration styles of different housing types. The metal texture surface technology is perfectly integrated with doors, windows and cabinets, enhancing the detailed texture of the residential space.

Commercial Complex Project: All-round Solution with One-stop Adaptability for Multiple Door Types and Scenarios

Project Background

A commercial complex project in the core business district of a city with a total construction area of about 80,000 square meters includes three major sections: shopping mall, Grade A office building and supporting commercial block, involving more than ten types of doors such as fire doors, aluminum alloy shop doors, solid wood office doors and glass partition doors. Moreover, different areas have significantly different performance requirements for hinges: fire doors in fire exits need to meet the requirements of automatic door closing and high-temperature stability; shop doors in shopping malls require high-frequency opening and closing as well as silent buffering; office doors in office buildings focus on use texture and stability. At the same time, the project construction period is tight, and different construction teams work crossly, putting extremely high requirements on the installation convenience and adaptability of hardware products.

Value of WEINI Hinges in Project Implementation

Compatible with all door types, solving adaptability problems in one stop: WEINI hinges are compatible with various door types such as fire doors, wooden doors, aluminum alloy doors and glass doors. There is no need to select separate products for different door types. The project party only needs to purchase one product uniformly to meet the door and window needs of the entire area of the commercial complex, which greatly simplifies the procurement process and reduces supply chain management costs.
Wide temperature adaptability and stable performance for complex commercial scenarios: The product has a wide temperature adaptability from -30℃ to 60℃. Fire doors in fire exits can still maintain stable automatic door closing and damping performance in high-temperature environments, meeting fire acceptance standards; shop doors in shopping malls are opened and closed more than 200 times a day.
Split structure for more efficient post-maintenance: After the commercial complex is put into operation, doors and windows are used frequently, making post-maintenance difficult. The innovative split structure of WEINI hinges allows the spring and damper to be disassembled and replaced separately without demolishing and modifying the door body and door frame.

Industrial Factory Project: Hard-core Quality Assurance with Stability and Durability in Severe Environments

Project Background

An intelligent manufacturing factory project in an industrial park is mainly used for high-end equipment production and warehousing. Some areas in the factory are constant temperature workshops, and some outdoor passages and warehousing areas face severe environments such as low temperature and dust. The steel doors and aluminum alloy protective doors in the workshops and warehousing areas need to meet the requirements of strong load-bearing capacity, wear resistance and low maintenance. Traditional hinges are prone to shaft corrosion and unsmooth opening and closing in such environments, requiring a comprehensive maintenance every six months on average, which affects production efficiency.

Value of WEINI Hinges in Project Implementation

Stable performance in severe environments: WEINI hinges are made of high wear-resistant and environmentally friendly materials, and have passed strict load-bearing and corrosion resistance tests. The precision technology of the shaft part effectively prevents dust from entering, and still maintains smooth opening and closing in the dusty environment of the factory; the low temperature adaptability of -30℃ ensures that the doors of outdoor passages will not have damping failure and difficulty in closing in winter, meeting the use requirements of industrial scenarios.
Stable bearing capacity for heavy doors: The single steel door in the factory warehousing area weighs 80kg. WEINI hinges have passed professional load-bearing tests, can stably bear the long-term use of heavy doors, and have no shaking or abnormal noise during opening and closing, ensuring the operational safety of factory staff.
Reducing long-term operation and maintenance costs: Combining the durable design with the split maintenance structure, the hinges do not require frequent maintenance after the factory is put into use, and only need a simple lubrication inspection every year. Compared with traditional hinges, the annual maintenance cost is reduced by 70%, saving a lot of operational labor and material costs for the enterprise.
