Maichen obtiene patente, marcando otro avance tecnológico.
Recently, Shandong Maichen CNC Equipment Co., Ltd., a professional enterprise with nearly two decades of dedicated experience in the CNC equipment field for door and window processing, has successfully obtained two utility model patents with independent intellectual property rights following years of in-depth technical research and development: “A Precision Positioning Device for Door and Window Profiles” and “Automated Corner Assembly Process for Multi-Material Profiles.” As a key enterprise engaged in the R&D, production, and sales of high-end intelligent equipment for door and window processing, Maichen CNC has always regarded technological innovation as the core driving force for its development. It allocates no less than 15% of its annual operating income to R&D each year and has built a professional R&D team consisting of senior engineers, industry technical experts, and doctoral researchers. The acquisition of these two new patents not only reflects the company’s unwavering pursuit of technological excellence but also marks another major breakthrough in its R&D capabilities in the core technical field of door and window processing. This achievement further accelerates the transformation of technological achievements from laboratory research to large-scale industrial application, enhancing the company’s discourse power and technical influence in the domestic and international mid-to-high-end door and window equipment markets.
These two newly authorized utility model patents are the outcome of Maichen CNC’s in-depth analysis of industry pain points and close alignment with market demand, aiming to address long-standing technical bottlenecks in the door and window processing industry. Regarding the “Precision Positioning Device for Door and Window Profiles,” the requirements for profile processing precision in the current door and window processing field—especially for high-end smart doors and windows and system doors and windows—are exceptionally stringent. Even a minimal positioning error may lead to issues such as excessive assembly gaps, uneven overall flatness, and reduced product durability. However, traditional profile positioning equipment on the market is mostly constrained by mechanical structure design and single sensing technology, making it vulnerable to external factors including profile surface oxidation, ambient temperature fluctuations (which amplify errors in high and low-temperature environments), and mechanical wear after long-term operation. As a result, positioning errors often fluctuate between ±0.05mm and ±0.1mm, failing to meet the precision requirements of high-end projects. To tackle this pain point, Maichen CNC’s R&D team has undergone hundreds of experiments and technical iterations, innovatively integrating “dual servo motor synchronous drive + high-precision laser displacement sensor real-time feedback + intelligent algorithm dynamic correction” technology. This device can capture micro-deviations in profile positioning within 0.001 seconds, automatically adjust the positioning mechanism via a built-in intelligent algorithm, and ultimately control the profile positioning error stably within ±0.01mm—a leading precision level in the industry. After practical application in production lines, this device not only reduces the assembly rework rate of door and window products by over 30% but also shortens the per-unit product processing cycle by 15%, effectively resolving the industry’s challenge in achieving high-precision profile positioning and providing strong support for the upgrading of high-end door and window manufacturing.
As for the “Automated Corner Assembly Process for Multi-Material Profiles,” with the continuous upgrading of consumption in the door and window market and the popularization of green building concepts, the demand for multi-material composite doors and windows (including aluminum, PVC, aluminum-clad wood, and aluminum-wood composite) has surged significantly. Nevertheless, due to the notable differences in physical properties (density, thermal expansion coefficient, hardness) and surface characteristics of different materials, traditional corner assembly processes have long faced persistent challenges: excessive pressure tends to deform aluminum profiles, while insufficient pressure results in weak bonding; high-temperature curing easily accelerates the aging of PVC profiles, while low-temperature bonding impairs sealing performance; for aluminum-clad wood profiles, the combination of wood and metal makes it difficult to balance bonding firmness and structural integrity. These issues directly lead to shortened service life of door and window products, poor airtightness and watertightness, and failure to meet the energy-saving and environmental protection indicators specified in the national “Green Building Evaluation Standard” (GB/T 50378-2019). Targeting these industry pain points, Maichen CNC’s patented process has implemented targeted optimizations for each mainstream material: for aluminum profiles, it adopts “low-pressure uniform pressing + anaerobic adhesive curing” technology to ensure firm bonding without deformation; for PVC profiles, it employs “temperature-controlled low-temperature curing + modified sealant” to avoid material aging while enhancing sealing performance; for aluminum-clad wood profiles, it innovatively designs a “mechanical interlocking + adhesive bonding” composite structure to balance firmness and structural stability. Practical tests indicate that compared with traditional processes, the corner assembly strength of products processed by this process is increased by over 40%, with airtightness reaching Grade 7 and watertightness reaching Grade 6 in accordance with the national standard (GB/T 7106-2019)—surpassing the average level of similar products in the market by two grades. This fully complies with the energy-saving requirements for Grade II and above green buildings and fills the industry gap in automated, adaptive corner assembly for multi-material profiles. Currently, both technologies have been fully applied to the company’s core product lines, including aluminum profile double-end CNC precision cutting saws, heavy-duty synchronous corner assembly machines, intelligent door and window processing production lines, and CNC drilling and milling machines. This has significantly improved the performance and competitiveness of these products in the mid-to-high-end market, driving a 25% year-on-year growth in the company’s high-end equipment orders.
To date, through continuous technological accumulation and innovative breakthroughs, Maichen CNC has accumulated more than 20 core patents, including 12 utility model patents and 8 invention patents. These patents cover the entire technical chain of door and window processing, such as precision cutting, intelligent drilling and milling, automated corner assembly, profile detection, and digital control systems. This comprehensive and systematic technological protection system not only effectively establishes a solid technical barrier for the company, preventing the copying and infringement of core technologies but also provides strong intellectual property support for the continuous iteration and upgrading of its products. Amid fierce market competition, these patents have become the core competitiveness that distinguishes Maichen CNC from its peers, helping the company gain a leading position in the high-end door and window processing equipment market and win widespread recognition from well-known domestic and foreign door and window manufacturers, engineering contractors, and building materials wholesalers.
Looking ahead, Shandong Maichen CNC Equipment Co., Ltd. will adhere to the development philosophy of “technology-driven, customer-centric” and continue to focus on the pain points and development trends of the door and window processing industry. The company plans to increase its R&D investment to 20% of its annual operating income within the next three years, expand its R&D team by recruiting more high-end technical professionals, and deepen industry-university-research cooperation with renowned universities and research institutions such as Shandong University of Technology and the China Building Materials Academy. In terms of R&D direction, it will focus on key areas including intelligent interconnection (realizing remote equipment monitoring and fault diagnosis), green energy conservation (reducing equipment energy consumption by 30% through technological optimization), flexible production (adapting to small-batch, multi-specification processing needs), and new material adaptation (developing technologies for carbon fiber and glass fiber composite profiles). The company is committed to accelerating the transformation of technological achievements, rolling out more efficient, precise, and cost-effective intelligent processing solutions for customers, helping door and window enterprises improve production efficiency, reduce operational costs, and enhance product quality, thereby making greater contributions to the high-quality development and technological upgrading of China’s door and window manufacturing industry.
