Context & Challenges
The company faced several constraints with time-pressure dispensing:
- Non-compliance with medical regulations
- Significant viscosity variation due to temperature changes in the workshop
- Inconsistent dispensing
- High reject rates
- Production delays
Implemented Solution
Given the significant variations in adhesive viscosity, the use of volumetric dispensing technology was essential to ensure process stability and control over the dispensed volumes — both critical to meeting the client’s quality requirements.
Key Features:
- Precise and repeatable dispensing using a linear stepper motor
- Compensation for viscosity variations
- Easy to operate and clean
- Programmable dispensing sequences
Equipment Used
Implementation of a PreciFluid 5 cc volumetric dispenser. Used in automatic mode (with each trigger, the dispenser performs a shot according to the parameters of the active program). A drop retraction (drawback) was configured to ensure clean and accurate cut-off of the material.
Precifluid® Dispenser
The PreciFluid® volumetric dispenser is a technological powerhouse dedicated to your dispensing needs.
Results & Benefits
- 85% reduction in non-conformities
- Improved volume repeatability to ±1.5%
- Process stabilization
- Reduction in overall reject rate from 12% to 2%
