Actuators

What are Dispensing Actuators?

A dispensing actuator is the finger-triggered head that releases the dosing stroke of a pump or airless dispenser. It converts finger pressure into a metered output calibrated at 0.23 ± 0.02 ml per stroke, with a 0.15-0.17 ml variant. Nozzle geometry shapes spray or stream pattern; metal springs (externally sourced) and PP bodies are standard in the family.

Formulation Compatibility & Applications

• Compatible Formulations: Airless-dispensed serums, lotions, treatment creams and sprays; actuators are matched to vehicle viscosity and output requirement.
• Target Packaging Use Cases: Airless skincare bottles, lotion pump bottles, sprayer configurations and dose-controlled treatment packaging where output per stroke must stay constant.

Engineering Materials & Sustainable Options

• Verified Materials: PP is the standard body material across the actuator family; metal springs are purchased components. Nozzle and internal gaskets follow family-level material norms.
• Eco-Friendly & PCR Solutions: PP and PCR PP suitability applies project-by-project; all-plastic actuator constructions are feasible. Actuator spring material and any metal-trim alternatives are specified at project level.

Customization & Secondary Processing

Actuator heads accept screen printing, pad printing, hot stamping and spraying/coating, plus color injection for brand-matched finishes. Nozzle orifice and thread options are available to tune spray pattern and output. Validate finish and performance limits with customization capabilities and the quality-control program.

Procurement FAQ

Q1: What neck finishes and output styles are available?

A1: The catalog covers 16/410, 18/400, 18/410, 20/400, 20/410, 20/415, 22/400, 24/400 and 24/410 closures. Standard output is 0.23 ± 0.02 ml per stroke with a 0.15-0.17 ml variant; configurations are confirmed per pump core.

Q2: How are actuator stroke consistency and leakage validated?

A2: Pump life-cycle testing verifies output stability across repeated strokes; leakage and vacuum tests confirm seal integrity; dosage/output testing measures per-stroke volume. All are part of the group's 12-category laboratory testing capability, with criteria set per project.

Q3: What are sampling and lead times for custom actuators?

A3: SLA 3D printing and prototype development accelerate first articles; tooling is developed in-house. Mass production and MOQ are confirmed against neck finish, output specification and decoration - quoted per project.
