3- Key Technical Points in Pump Core Manufacturing
Material selection
| Component | Materiale | Key Performance Requirements |
| Spring | Stainless steelSUS304/SUS316 | Salt Spray Test: 96 Hours Without Corrosion （5%NaCl） |
| Piston seal ring | PTFE/Modified PE | Alcohol solvent resistance: Swelling rate < 1.5% |
| Valve ball | Glass/plastic/SUS316 | ball roundness error≤0.01mm |
| Pump body | PP/HDPE (food grade) | Resistance to essential oil migration (Ethyl Caprate test) |
Challenges in Pump Core Manufacturing
- Spring Winding: CNC machines control wire diameter to ±0.02mm, eliminating stress and temper deformation.
- Sealing Surface Machining: Piston rod mirror polishing(Ra ≤0.2μm),reduces friction coefficient.
- Ultrasonic Welding: Energy precision to ±5J prevents thermal deformation of plastic parts.
- Clean Assembly: Class 1000 cleanroom to prevent particulate contamination.
Compatibility and Reliability Testing
A- Compatibility Validation:
- 72-hour product immersion test (mass change rate ≤0.5%)
- Low-temperature (-20℃) / High-temperature (50℃) cyclic impact 3 times
B- Functional Reliability:
- 5,000 continuous presses (dispensing volume fluctuation ≤±10%)
- 24 hour inverted suspension with no leakage
4- Iteration and Development of Technology
Eco-friendly pump core structure
- Replaceable structure design: Achieves 80% plastic reduction (with replaceable refills)
- Metal free spring structure: Air-driven, it overcomes metal recycling complexities
Intelligent Pump Core Features
- Piezoelectric sensor for dosage tracking (provides refill alerts)
- Antimicrobial surface treatment (with Octenidine Hydrochloride)
