custom hardware manufacturing is not simply changing a size, finish, or logo. A successful project connects design review, material selection, prototyping, testing, mass production, and quality control so the approved sample can be reproduced consistently at scale.
For an OEM hardware project, working directly with a custom hardware manufacturer gives buyers better control over specifications, production changes, quality standards, and delivery planning. A manufacturer can coordinate engineering, raw materials, machining, welding, polishing, assembly, testing, and packaging within one production system.
HANGFAT was established in 1994 and integrates product development and manufacturing. Its production lines support up to 800,000 pairs or sets per month, providing capacity for both product development and bulk supply programs.
A typical oem hardware manufacturing process starts with drawings, samples, dimensions, target market, required finish, expected order volume, and applicable standards.
The project then moves through:
Design and specification review
Material and structure confirmation
Prototype or sample development
Performance and appearance testing
Pre-production approval
Bulk manufacturing
In-process inspection
Final inspection and packaging
For ODM projects, manufacturers can also support structural improvement, material selection, finish development, and production feasibility.
Material selection should match the installation environment. For door hardware, HANGFAT offers SUS304 and SUS316 stainless steel, together with satin, polished, PVD, electrophoresis, and powder-coated finishes.
Quality checkpoints should cover material, dimensions, welding, surface consistency, assembly, function, corrosion resistance, and durability. EN 1906 defines 100,000 cycles for durability Grade 6 and 200,000 cycles for Grade 7, providing a useful reference for high-use door furniture.
One HANGFAT stainless steel lever handle can be configured for 200,000-cycle durability and EN 1670 corrosion performance from 96 to 480 hours, depending on the required grade.
Before approving mass production, the project sourcing checklist should confirm material grade, dimensions, finish sample, Lock compatibility, door thickness, testing requirements, packaging, order quantity, delivery schedule, and destination-market compliance.
For export projects, standards such as EN 1906 and EN 1670 should be confirmed before production rather than after goods are finished. HANGFAT also maintains certifications and test records including EN 1906, EN 1670, ISO 9001, ISO 14001, and RoHS-related documentation.
A controlled OEM and ODM process turns customization from a sample-making task into a repeatable manufacturing system, helping large orders maintain the same specifications, finish, function, and compliance requirements from the first unit to the final shipment.
