Customer Challenges
Improve Material Stability Before Potting
Stable dispensing begins with properly prepared material. Storage conditions, sedimentation, trapped air and viscosity changes can all affect the final potting result.
A customer using polyurethane potting material experienced frequent outlet blockages and inconsistent curing. Inspection showed a thick layer of pale-yellow crystals inside the curing-agent tank. Ambient moisture had entered the tank and reacted with the moisture-sensitive curing agent.
Other common problems include settled fillers, uneven material composition, trapped bubbles and poor flow caused by high viscosity. These conditions can lead to unstable dispensing, visible bubbles, incomplete curing and unnecessary material waste.
Baolan Resin Preparation Units control storage and pretreatment through reliable tank sealing, continuous stirring, optional vacuum degassing and optional heating. The prepared material can then be supplied to the metering and dispensing system under more consistent conditions.
Product Overview
Controlled Material Storage and Pretreatment in One Unit
Baolan Resin Preparation Units are installed upstream of the metering and dispensing system. They store and prepare potting materials before those materials enter the production process.
Each unit can combine a sealed material tank, stirring mechanism, vacuum degassing function, heating function, material connections and control components in an integrated frame.
Functions can be selected according to material characteristics and process requirements. The modular design also supports future configuration upgrades after equipment delivery.

Core Functions
Key Features
Reliable Tank Sealing
A pressure drop of less than 10 kPa over 12 hours helps protect moisture-sensitive materials and reduce crystallization, contamination and outlet blockage.
Continuous Material Stirring
Controlled stirring keeps fillers evenly distributed and helps maintain consistent material properties throughout production.
Vacuum Degassing
Optional vacuum treatment removes trapped air before dispensing, helping reduce bubbles, internal voids and surface defects.
Controlled Heating
Optional material heating improves the flow of suitable high-viscosity compounds and supports stable material transfer.
Modular Configuration
Preparation functions can be selected and upgraded according to material properties, production requirements and future process changes.
Organized Construction
Electrical cables, pneumatic tubing and material hoses are arranged within an integrated frame for a clean appearance and convenient maintenance.

Frequently Asked Questions
FAQ
What materials can be used with Resin Preparation Units?
The units can be configured for polyurethane, epoxy, silicone and other industrial potting compounds. The final configuration depends on material properties and process requirements.
Why is tank sealing important for polyurethane curing agents?
Some polyurethane curing agents react with ambient moisture. Reliable tank sealing helps reduce crystallization, contamination and material outlet blockage.
Can Resin Preparation Units remove bubbles from potting compounds?
Yes. An optional vacuum degassing configuration can remove trapped air before dispensing and help reduce bubbles and voids in finished products.
Can high-viscosity materials be heated?
An optional heating function can be configured for suitable materials to improve flow and support stable material transfer.
Can the preparation functions be customized?
Yes. Stirring, vacuum degassing and heating functions can be selected according to the material and application. The modular design also supports future configuration upgrades.
Can Resin Preparation Units be integrated with dispensing systems?
Yes. The units supply prepared material to metering and dispensing equipment. Connection details should be configured according to the selected system and production process.
