Product Specifications
Model and Power
The product model is DDDC047, with power ranging from EN2 to EN4 levels, which can flexibly adapt to the closing requirements of different door weights. This broad power range enables a product to meet multiple application scenarios, simplifying the selection and inventory management for buyers. Whether it's indoor doors that require gentle closure or access doors that require stronger closing force, this Cam Action Door Closer can provide precise force control.
Door body adaptation
The maximum applicable door width of the product is 1100 millimeters, and its load-bearing capacity ranges from 25 kilograms to 85 kilograms, demonstrating its excellent load capacity. This broad adaptability ensures that it can be installed on the vast majority of standard and weighted door leaves. Its powerful load-bearing performance complements the concept of Heavy Duty Invisible Hinge, providing concealed and strong support and closing force for the door leaf.
core functionality
This door closer integrates practical back inspection function. When the door leaf is opened to a specific angle, this function provides a buffering resistance, effectively preventing the door handle from hitting the wall or the door leaf from being damaged due to excessive force. This not only protects the door furniture and decoration, but also reduces subsequent maintenance costs. This feature forms a core linkage with the Cam Action Door Closer host, enhancing the overall durability of the product.
Material and Processing
The main material of the product is aluminum alloy, which ensures structural strength while effectively controlling overall weight and has good corrosion resistance. The surface is treated with silver, with a uniform and modern color that can naturally blend into the design of most doors and frames, maintaining the aesthetic effect of concealed installation. This material combination is the foundation for achieving Heavy Duty Invisible Hinge functionality and long-lasting service life.
Product features and advantages
Advantages of cam transmission
The core of this product is the Cam Action Door Closer design. The cam transmission mechanism converts the closing process into more efficient and smooth force transmission through precise curved profiles. Compared with traditional gear or slide rail structures, it can provide better performance during the start-up and locking stages, effectively reducing friction and noise, and bringing a smooth and quiet closing experience. This difference in principle makes it significantly better than ordinary products in terms of smoothness and durability.
Strong concealed support
Although the product has a hidden design, its performance is uncompromising. Its aluminum alloy body provides excellent structural strength and can withstand the daily operation of heavy-duty door leaves for a long time. This characteristic of 'containing a thousand treasures' makes it a true Heavy Duty Invisible Hing solution, perfectly solving the engineering problem of both aesthetics and load-bearing capacity, providing buyers with a competitive advantage in the high-end market.
Humanized function integration
The integrated back inspection function is a highly practical design. It is not an independent component, but works in conjunction with the Cam Action Door Closer host. When the door leaf is excessively opened, it can instantly provide cushioning and absorb impact energy. This not only protects the doors, locks, and walls, but also enhances the user's sense of security, reflecting the product's careful consideration of user experience and long-term usage costs in details.
Application Scenarios
Office and Commercial Buildings
Within modern office complexes, these products are extensively utilised in executive offices, meeting rooms, and main corridor doors. The Aluminium Concealed Double Swing Door Cam Action Door Closer maintains a clean façade, seamlessly integrating with premium interior designs. Its reliable automatic closing function ensures privacy and energy efficiency. The smooth operation creates a professional, tranquil atmosphere within the workplace.
Hotels and Clubs
Star-rated hotel rooms, exclusive clubs, and resorts present ideal applications for this door closer. Its concealed design preserves the integrity of interior aesthetics, while the Cam Action Door Closer's gentle closing action effectively prevents door slam noise, offering guests a tranquil and comfortable retreat. The back-check function further safeguards costly interior finishes from damage caused by door handles.
Premium Residential Projects
Suited for entrance doors and interior partition doors in luxury apartments and villas. It elevates the property's overall sophistication and contemporary appeal while providing safe, convenient access for residents, particularly the elderly and children. Its reliable closing action ensures doors remain securely shut, helping maintain indoor temperatures and enhance sound insulation – meeting the demands of premium residences for quality living.
Operation and Installation
Operating Instructions
Using this Cam Action Door Closer is remarkably straightforward and intuitive. During normal operation, simply push the door leaf open as with any conventional door. Upon release, the closer will automatically take over, controlling the door leaf to close smoothly and at a consistent speed until the latch engages. Users may fine-tune the closing speed and force using the dedicated tool via the product's built-in adjustment valve. This allows adaptation to specific door weights and usage preferences, achieving optimal closing performance.
Preparation Steps
Prior to installation, verify that both door weight and width fall within the product's specified range. Prepare suitable routing tools to precisely cut recesses in the door leaf and frame for housing the closer mechanism. Carefully study the installation diagram provided with the product to confirm mounting position and orientation. Ensure the door leaf and frame are perfectly vertical and horizontal, as this is fundamental to the Cam Action Door Closer's optimal performance.
Professional Installation Procedure
During installation, precisely locate and slot the door leaf edge and frame according to the template. Subsequently, embed the closer body into the door leaf slot and the linkage arm assembly into the frame slot. Secure all components firmly using the provided screws. Finally, connect the linkage arm to the body and fine-tune the closing force and speed adjustment valve based on practical usage. Professional installation is recommended to ensure functionality and longevity.
Customer Value
Enhancing Project Quality and Aesthetics
The incorporation of this concealed Cam Action Door Closer significantly elevates the overall calibre of a project. Its fully concealed design within the door frame preserves clean, uninterrupted lines, aligning with contemporary minimalist design trends. Purchasers can thereby offer end clients more appealing and sophisticated spatial solutions, enabling them to stand out in competitive markets and secure greater opportunities for high-end projects.
Reduced Long-Term Maintenance Costs
The product's robust aluminium alloy construction and precision cam-driven mechanism ensure exceptional durability and reliability, withstanding high-frequency use while drastically minimising repair or replacement needs due to malfunctions. The integrated backcheck function directly prevents damage to door panels and walls, avoiding associated repair costs. This enables purchasers to offer clients products with lower failure rates and more favourable lifecycle costs.
Enhanced Safety and Comfort
The Cam Action Door Closer delivers a smooth, quiet closing experience, eliminating the startling noise and pinch hazards associated with abrupt door slams. This makes it particularly suitable for households with elderly residents or children, as well as quiet-seeking environments such as hotels and offices. Its reliable automatic closing function ensures fire doors and partition doors remain securely closed, enhancing safety, privacy, and energy efficiency within spaces.
