Existing housing market presents a new opportunity for equipment upgrades.

With the acceleration of urban renewal initiatives and the implementation of the “trade-in” policy, the demand structure of China’s door and window industry has undergone a fundamental transformation, with the demand for window replacement in existing housing stock becoming the core engine of market growth. Data shows that the domestic door and window industry market size reached 400 billion yuan in 2025, with the demand for window replacement in existing housing stock accounting for over 50%, and this proportion is expected to rise to over 65% by 2030, directly driving a structural dividend in the door and window processing equipment market.

Unlike the demand for new commercial housing, the window replacement scenario in existing housing stock places higher demands on the flexibility, precision, and efficiency of equipment, requiring adaptation to differentiated needs such as the renovation of old profiles and customization of multiple specifications and sizes. Against this backdrop, automated processing equipment with flexible production capabilities, precision positioning devices, and rapid debugging systems have become industry necessities, shortening the equipment replacement cycle from the previous 5-8 years to 3-5 years.

Industry analysts point out that the explosive growth of the existing housing stock market will force equipment manufacturers to accelerate technological iteration, focusing on the processing needs of “small batches, multiple batches, and high precision.” Leading companies such as Maichen CNC have taken the lead in adapting to the renovation of existing housing stock, providing efficient solutions for the industry, thanks to their ±0.02 mm precision machining technology and flexible production lines.
