Manufacturing Process
100% owned and operated production base provides reliable large-scale manufacturing.
Hardware Production
After a careful preparation of raw materials, we produce lighting hardware in a semi-automatic way. Our professional equipment produces hardware of high quality and durability.
- Laser marking
- Assembly of heat diffusers
- Welding of the light source
- Application of thermal grease
Product Assembly
With the help of clear product structure and rational design, our assemblies become efficient and precise. We offer robust lamps that meet the market demand.
Installation of the lens
Assembly of the lamp shell
Fixing the inner and outer ring
Inserting the spring
Testing
Testing electrical parameters is an essential part of the production process, and our experienced inspectors implement the principle of 100% good quality to provide you with safe lighting.
Aging test
Color temperature test
Performance Inspection
Heat dissipation test
Inspection & Packaging
We carry out a thorough inspection of all aspects of the finished product before shipping, and then pack it tightly to prevent damage to the fixture in transit.
Light Body Cleaning
Labeling
Supplying Instruction Manual
Quality Assurance
committed to achieving a 100% product test pass rate before shipment. Further products have also passed CCC and CE certifications. level 2 sampling and testing standards
Material Inspection
HOJA places special emphasis on the quality management of raw materials, as all incoming materials must undergo rigorous quality testing to ensure smooth production and subsequent processing.
We use important testing equipment to conduct various tests on incoming materials, such as salt spray tests, temperature tests and electronic tests.
Fabrication Inspection
During the production process, we conduct no less than three-stage inspections, namely inspection of the manufacturing process, inspection of the first finished product, and random inspection of the product.
Our quality inspectors check that each process complies with SOPs based on BOM and the specification sheets, perform touring inspections on the floor, and record the inspection results on the form.
Finished Product Inspection
Final full inspection of the product is crucial and we insist 100% pass inspection before shipment.
Our inspection department uses a photoelectric parameter tester with integrating sphere to check the luminous flux, color temperature and luminous efficiency of the light source, and then verifies the light brightness and light angle with a light distribution curve tester.
