Vacuum Chamber Dispensing Solutions
Precision potting, bubble-free bonding, and scalable automation engineered for modern manufacturing.
Vacuum Chamber Dispensing is transforming the way advanced industries apply adhesives, sealants, and potting materials. From aerospace electronics to automotive sensors and medical device encapsulation, manufacturers rely on this method to eliminate air bubbles, improve flow into micro-cavities, and ensure long-term reliability.
At Dispense Robotics, we specialize in fully integrated vacuum chamber dispensing systems, supported by robust material feeding solutions and pressure tanks to deliver a complete, end-to-end process with accuracy, repeatability, and safety.
What Is Vacuum Chamber Dispensing?
Vacuum chamber dispensing refers to the process of applying materials such as adhesives, encapsulants, or fillers within a sealed vacuum chamber. By pulling a vacuum around the part and the material, trapped air is removed from both the substrate and the fluid, resulting in:
- Bubble-free application
- Improved adhesion and coverage
- Controlled material flow into complex geometries
- Enhanced durability in harsh environments
This method is essential in industries where air inclusion could lead to insulation failure, reduced strength, or moisture penetration.
VC Series Precision Vacuum Chamber Dispensing System
The VC Series from Dispense Robotics is engineered specifically for automated vacuum chamber dispensing with full control over vacuum levels, XY motion paths, and dispense timing. Built for flexibility and reliability, it’s ideal for electronics, optical bonding, battery systems, and more.
Key Features:
- Automated XY Dispensing: Infinite position control inside the chamber
- Programmable Recipes: Save and execute predefined motion, vacuum, and dispensing parameters
- Vacuum Performance: Down to 2 Torr (29.84 inHg)
- Pull-Down Time: 30 seconds to 2.5 minutes
- Touch Interface: 5×7” HMI for intuitive control
- Chamber Sizes: 18″–24″ standard (custom on request)
Typical Workflow:
- Place the part in the vacuum chamber
- Select a dispensing recipe
- System pulls vacuum and executes XY dispensing
- Chamber vents to atmosphere for part removal
This system is optimized for batch production, development labs, and mid-volume automation where vacuum potting and bonding precision is critical.
Material Feeding System – MFS/MFE Series
A critical part of any vacuum chamber dispensing system is stable, continuous material delivery. The MFS/MFE series feeding units ensure smooth supply of 1K or 2K materials bubble-free and fully controlled without requiring compressed air.
Core Benefits:
- Continuous and infinite material supply per tank
- Vacuum degassing for air-free fluid transfer
- No compressed air required, improving safety
- Optional heating and stirring functions for temperature-sensitive or filled materials
- Economical and scalable solution for long-term production
The MFS/MFE series works in perfect synergy with your vacuum chamber, ensuring the fluid delivered is already conditioned and degassed ready for precision application.
Pressure Tanks – 20L Bottom-Port SUS304 Tanks
To support consistent and contamination-free fluid handling, our stainless steel pressure tanks are engineered with industry-proven durability and easy maintenance.
Tank Specifications:
- Material: SUS304 stainless steel
- Capacity: 20 liters
- Bottom outlet: BSPT 3/8” female (top port optional)
- Wide opening: Easy filling and cleaning
- Pressure: Operates at 0.5 MPa
- Sealing Options: NBR, Viton (capsule), Silicone, EPDM
- Polishing: Buff finish for clean flow and hygiene
Dimensions:
| Parameter | Value |
| A | 728.7 mm |
