Choosing a custom door hardware manufacturer should go beyond comparing quotations. For branded products and project orders, buyers need to know who controls production, whether specifications can be repeated in bulk, and whether the hardware can meet the required market standards.
A direct manufacturer can control material selection, machining, welding, polishing, assembly and inspection. This becomes critical when an approved sample must be reproduced across thousands of sets.
Established in 1994, HANGFAT integrates product development and manufacturing and provides OEM and ODM services. Its production capacity reaches approximately 800,000 pairs or sets per month, according to HANGFAT factory information.
A reliable OEM door hardware manufacturer should evaluate more than appearance. Before development, confirm:
Drawings and dimensions
Door and Lock compatibility
SUS304 or SUS316 material
Surface finish
Performance requirements
Order quantity
Packaging
Destination market
OEM is suitable when specifications are already defined, while ODM offers greater support for structural development and manufacturing optimization.
Door hardware quality depends heavily on process control. HANGFAT uses equipment including 3D automatic welding and automatic polishing machines to improve welding consistency and surface quality.
The manufacturing process should include material inspection, forming or machining, welding, polishing, surface treatment, assembly and final inspection. For bulk supply, every stage should have measurable checkpoints.
A sourcing decision should be based on test data rather than general claims.
For example, HANGFAT's Stainless Steel U Form EN Standard Lever Handle is available in stainless steel and its SUS304 satin configuration can reach 480 hours of corrosion testing.
Under BS EN 1906, durability Grade 6 represents 100,000 operating cycles, while Grade 7 represents 200,000 cycles. These figures provide a useful benchmark when sourcing hardware for frequent-use applications.
A practical project sourcing checklist should also include EN 1906 performance, EN 1670 corrosion resistance, material documentation, approved samples, packaging requirements and inspection criteria.
Export compliance should be confirmed before tooling and mass production begin. Changing materials or structures after testing can affect both performance and delivery schedules.
The right door hardware manufacturer for OEM projects should therefore combine development support, controlled manufacturing, measurable quality checkpoints and sufficient bulk production capacity. HANGFAT's long-term manufacturing experience, OEM and ODM capability, automated production equipment and established door hardware testing standards provide a structured foundation for customized brand and project sourcing.
