Spindose: precise and recyclable dosing system for sprays and emulsions
SpinDose integrates handed shearing auxetics with a progressive cavity pump for precise, recyclable dispensing of materials from 1 to 10000 cP. It's compatible with various viscosities, ensuring accurate dosing without leakage, and is customizable for different needs.
Overview
SpinDose offers an innovative solution for the precise dispensing of sprays and emulsions by integrating handed shearing auxetics (HSAs) with a progressive cavity pump. This system is designed to handle materials with viscosities ranging from 1 to 10000 cP, ensuring accurate dosing without leakage. The pump is constructed from recyclable HDPE, highlighting its sustainability. By converting linear compression into rotational motion, the SpinDose system achieves precise volume delivery and is scalable for various applications.
Technical specifications
- Precision dispensing: Utilizes a progressive cavity pump to create sealed chambers for accurate volume control.
- Handed shearing auxetics: Functions as both a spring and a screw, enabling linear-to-rotational motion conversion.
- Material compatibility: Handles a wide range of viscosities, from sprays to gels.
- Recyclable design: Constructed from HDPE, allowing for sustainable manufacturing.
- Customization: Scalable and customizable to meet diverse dispensing requirements.
Technology readiness level
SpinDose is currently at Technology Readiness Level 3. The project will undergo a structured development process in four phases over 12 months to enhance its feasibility, simulation accuracy, prototype testing, and prepare for scalable manufacturing. The initial phases will focus on CAD modeling, digital simulation, and 3D prototype testing, leading to a final phase concentrating on injection molding design.
