Behind every OEM order at Weitai Group is a production floor designed around one idea: quality is built in the process, not checked at the end.
In this article we take you inside our cleanroom production lines — the environment, the people, and the systems that turn raw formulas into finished, export-ready products.
## Cleanroom environment: the first layer of protection
Our filling and packaging operations run in clean, dust-controlled workshops. The environment itself is a quality tool:
- Controlled air flow with filtration to reduce airborne particles
- Smooth, easy-to-sanitize surfaces
- Clearly separated zones for different process stages
- Strict hygiene rules for operators: dust-proof suits, gloves, masks
For water-based skincare and cosmetic products, this level of environmental control is not optional — it is the foundation of product safety and stability.
## People: skilled operators, consistent standards
On our lines, operators work in teams along stainless-steel conveyors. Each station has a defined task — assembly, filling, inspection, packing — and each operator is trained to follow the same documented procedure every time. This combination of clear standards and skilled people is what keeps batch-to-batch quality consistent.
## Systems: certification and traceability
Our production follows internationally recognized quality frameworks, including ISO 22716 cosmetics GMP and GMPC. Every batch is:
- Documented from raw material intake to finished goods
- Given unique batch numbers for full traceability
- Subject to in-process checks and retained samples
These systems give our OEM and ODM customers the documentation they need for audits, registrations, and export clearance.
