Production is centralized at our 6,000m² facility in Shenzhen. The plant runs six dedicated lines for whitening kits, pens, strips, powders, pastes and oral-care devices. This page documents the facility's capacity, equipment and quality workflow at the level customer audits expect.
Facility overview
The plant is organized into four functional zones: production (six lines), R&D, quality control, and warehouse. Each zone is staffed and audited independently. Material flow runs uni-directionally - raw materials enter at the warehouse, exit at the shipping dock - to keep cross-contamination risk low.
| Zone | Function | Notes |
|---|---|---|
| Production hall | Six dedicated lines - gel, strips, powder, paste, devices, pens | Class 100,000 cleanroom for gel filling and primary packaging |
| R&D laboratory | Formulation development, stability testing, accelerated aging studies | PhD-led team; 240+ active formulations on file |
| QC laboratory | Incoming raw material testing, in-process sampling, finished goods release | Microbiological, pH, viscosity, active concentration assays |
| Warehouse | Raw material and finished goods storage | 1,500 m² FIFO inventory climate controlled for active ingredients |
Production lines
The figures below are sustained daily output, not peak capability. Lead times include in-line QC and pre-shipment inspection.
| Line | Daily capacity | Production lead time |
|---|---|---|
| Whitening kits (gel + LED accelerator) | 15,000 units | 15-20 days |
| Whitening pens & syringes | 30,000 units | 10-15 days |
| Whitening strips | 50,000 units | 20-25 days |
| Powders & pastes | 20,000 units | 10-20 days |
| Electric oral-care devices | 8,000 units | 20-25 days |
| LED accelerator lights (standalone) | 5,000 units | 15-20 days |
Equipment
-
Automatic gel fillers
2% volume accuracy across the production run, verified by hourly fill-weight checks.
-
Inline vision inspection
Camera-based defect detection at the carton-seal station; reject rate logged to the batch record.
-
Ultrasonic sealing
Used for syringes and pen applicators where heat sealing would compromise the active. Seal-integrity samples pulled per AQL 1.5.
-
HEPA-filtered air handling
Class 100,000 in primary packaging zones. Differential pressure monitored continuously; logs available with batch records.
Quality workflow
-
Raw material verification
Certificate of Analysis review on receipt, plus in-house assay (active concentration, microbiological) before release to production.
-
In-process control
pH, viscosity and active concentration measured at fixed intervals throughout the production run. Out-of-spec readings trigger line stop and root-cause investigation.
-
Pre-shipment release
Visual, dimensional and functional checks at AQL 1.5 / 2.5 / 4.0 levels depending on customer specification.
-
Documentation and retention
Batch record, retain samples and Certificate of Analysis archived; copies supplied to customer with each shipment.
Audits and customer visits
The plant hosts third-party audits on a six-month cadence (SGS, Intertek, BSCI, SEDEX). Customer-specific audits are scheduled separately and we provide access to the lot records, supplier traceability and audit reports that the auditing team requires.
| Visit type | Format |
|---|---|
| Virtual factory tour | Live video walk-through of production floor, R&D and QC labs - 30 minutes, scheduled by appointment. |
| On-site customer visit | Shenzhen facility, by appointment. Visa support letter issued on request. Travel from SZX airport is ~45 minutes by car. |
| Third-party audit | SGS, Intertek, BSCI, SEDEX, or customer-nominated auditor. Audit pack (procedures, batch records, supplier list) prepared in advance. |
