How to adapt the internal structure design of cosmetic pumps to cosmetics with different viscosities

In the cosmetics industry, the diversity of product viscosities creates significant challenges in the design of the internal structure of cosmetic pumps. As the core component of cosmetic packaging, the internal design of cosmetic pumps directly affects the pumping efficiency, stability and user experience of the product. Therefore, the internal structure design of cosmetic pumps has undergone continuous innovation and optimization for cosmetics with different viscosities.

Effect of viscosity on cosmetic pumps
The viscosity range of cosmetics is extremely wide, from low-viscosity aqueous liquids to high-viscosity creams and gels, and each type of product has its own specific viscosity requirements. Viscosity not only determines the fluidity of the product, but also directly affects the resistance and required pressure during pumping. For low-viscosity cosmetics, such as lotions and essences, less resistance is required during pumping, so stable pumping can be achieved at lower pressure; while for high-viscosity cosmetics, such as face creams and eye creams, pumping The resistance that needs to be overcome is greater, so greater pressure must be applied to ensure stable pumping effect.

Cosmetic pump internal structure design principles
In order to effectively adapt to cosmetics with different viscosities, the internal structure design of cosmetic pumps should follow the following key principles:
Flow channel optimization: The internal flow channel design should strive to be smooth to reduce resistance during pumping. For high-viscosity cosmetics, the flow channel design needs to be more complex to enhance the pressure during the pumping process to ensure that the product can be pumped out stably and continuously.
Cooperation between piston and cylinder: The cooperation between piston and cylinder is the core element of cosmetic pump design. In order to ensure the stability and sealing of the pumping process, the fit between the piston and the cylinder must be tight and wear-resistant. For high-viscosity cosmetics, material selection is particularly important, as they need to have higher strength and hardness to cope with greater pressure.
Spring design: As a key component in cosmetic pumps, springs directly affect the pressure during pumping. The spring design should be adjustable so that the pressure can be adjusted according to the viscosity requirements of different products.

Internal structural design innovation
In order to meet the needs of cosmetics with different viscosities, the internal structural design of cosmetic pumps is constantly innovating, and a variety of new design concepts and structural forms have emerged.
Adjustable flow channel design: Some cosmetic pumps adopt an adjustable flow channel design to adapt to cosmetics with different viscosities by changing the shape and size of the flow channel. This design not only improves the stability of pumping, but also effectively reduces production costs and inventory pressure.
Multi-stage pumping structure: In the face of high-viscosity cosmetics, some cosmetic pumps have introduced a multi-stage pumping structure, using the combination of multiple pistons and cylinders to achieve higher pumping pressure and more stable pumping effects.
Intelligent control system: With the rapid development of intelligent technology, some cosmetic pumps have begun to integrate intelligent control systems. Through built-in sensors and control modules, the viscosity and pumping pressure of cosmetics can be monitored in real time, and the output volume and pressure of the pump head can be automatically adjusted to achieve More precise and stable pumping effect.
