18/410 20/410 External Spring Double Shell Straight Closure alu. Cream Treatment Foundation Pump dispenser

Discover the next generation of cosmetic dispensing with our Professional Treatment Pump, engineered for brands that refuse to compromise on quality. Available in both 18/410 and 20/410 closure sizes, this outer spring airless pump represents the perfect fusion of precision engineering and luxurious user experience. Specifically designed for vacuum bottle applications, this dispensing solution elevates your skincare formulations to prestige status.

Innovative Outer Spring Architecture for Formula Protection

Total Isolation Technology
The pharmaceutical-grade external spring mechanism sets a new standard for formula integrity. Unlike conventional lotion pumps that expose sensitive ingredients to metal contact, our patented spring design positions the metal component entirely outside the product flow path. This barrier system ensures that high-value active ingredients—including stabilized vitamin C, retinol complexes, and peptide blends—remain chemically pure throughout the product lifecycle. The result is contamination-free dispensing that maintains efficacy from first use to final drop.

Precision Engineering for Consistent Performance
Every treatment pump undergoes rigorous flow rate calibration to deliver the exact dosage your formulation requires. The airless vacuum technology employs a follow-plate piston that rises seamlessly as product is dispensed, creating a hermetic seal that blocks oxygen ingress and bacterial contamination. This vacuum reservoir system eliminates the need for preservatives in many formulations, appealing to the growing clean beauty market segment.

Dual Closure Options for Maximum Design Flexibility

Universal Compatibility Features
With both 18/410 and 20/410 neck finish options, this dispensing closure adapts to virtually any standard vacuum bottle in the market. The threaded pump assembly ensures secure attachment while maintaining a sleek profile. Whether you're launching a intensive night treatment or a lightweight daily serum, the interchangeable actuator options allow you to customize output volume from 0.1cc to 0.3cc per stroke.

Premium Aesthetic Customization
The electrified aluminum (anodized aluminum) components transform a functional dispenser pump into a brand signature piece. Our surface finishing department offers:
● Brushed metal finishes for contemporary minimalism
● High-gloss metallics for luxury positioning
● Gradient anodization for distinctive shelf appeal
● Embossed logos and debossed branding elements

Manufacturing Excellence – Where Precision Meets Artistry​​​
Advanced Production Capabilities
Our ISO-certified manufacturing facility houses state-of-the-art injection molding machines with robotic part handling systems. The clean room assembly environment maintains Class 100,000 standards, ensuring that every cosmetic dispenser meets the strict hygiene requirements of premium skincare. We utilize food-grade polypropylene and medical-grade LDPE for all wetted components, exceeding global regulatory standards.

Comprehensive Quality Management
From incoming raw material inspection to final functional testing, our quality assurance protocols leave nothing to chance. Each pump assembly undergoes:
● Automated leak detection under vacuum pressure
● Cycle life testing exceeding 10,000 actuations
● Torque testing for closure integrity
● Dimensional verification using CMM equipment

End-to-End Supply Chain Solutions
As a vertically integrated packaging manufacturer, we control every aspect of production. Our in-house tool shop maintains all molds for consistent quality, while our injection molding department operates 24/7 to meet demanding production schedules. The automated assembly lines can produce over 2 million units monthly, with real-time monitoring systems tracking every parameter.


Sustainable Innovation in Airless Technology​​​
Eco-Conscious Design Elements
Recognizing the industry shift toward sustainable packaging, our treatment pump incorporates recyclable materials and reduced-component design. The mono-material construction options facilitate easier recycling, while the airless system itself reduces product waste by ensuring complete evacuation—typically achieving 98%+ evacuation rates compared to 85% with traditional dip-tube systems.

Future-Ready Customization
Our research and development team continuously explores innovations in micro-dispensing technology and smart packaging integration. Current projects include child-resistant versions for CBD formulations and airless systems compatible with post-consumer recycled materials. We collaborate closely with brand development teams from concept through commercialization, offering 3D prototyping and short-run sampling for market testing.
