01 / Manufacturing
Hi-Tech Manufacturing Equipment
We adopt high-tech manufacturing equipment that meets AQL standards. Our production lines are designed for precision, consistency, and scalability — enabling us to handle bulk OEM and ODM orders with reliable turnaround times.
From automated injection molding to precision circuit assembly, every stage of production is optimized for quality and efficiency.
02 / Production
Automated Assembly Lines
Our workshop floors are organized for lean manufacturing. Automated and semi-automated assembly lines produce consistent, high-quality units at scale — from compact car diffusers to commercial HVAC scent systems.
Each workstation follows standardized operating procedures with traceable batch records, ensuring every product meets client specifications.
03 / Quality Control
Strict Quality Assurance
We maintain dedicated IQC and OQC teams to ensure all materials and finished products meet AQL criteria. Every unit undergoes three stages of testing before shipment.
- Incoming material inspection (IQC) for all components
- In-process quality checks at each assembly stage
- Final OQC with functional testing, aging tests, and cosmetic inspection
- 4-hour aging test before packing for dispenser products
04 / Research & Development
Strong R&D Strength
Our R&D department brings together experienced engineers with deep expertise in sensor technology, fluid dynamics, and product design. All team members have worked in the dispenser and diffuser industry for many years.
We offer complete OEM and ODM services — from initial concept and ID design to prototyping, mold development, and mass production. Private labeling and fully customized designs are available to match your market requirements.
