4.Capacitor/Terminal Potting
Applications: Electrolytic capacitors, filter capacitors, and terminal blocks.
Function:
Leakage prevention: Fills gaps in high-voltage capacitors.
Mechanical reinforcement: Prevents terminal loosening (e.g., charging station power supply terminals).
5.New Energy Power Supply Equipment
●Application Scenarios:
Charging Pile: Charging Module Potting (requires flame-retardant adhesive, such as UL94 V-0).
Energy Storage Battery: BMS Management System PCB Potting.
Photovoltaic Inverter: Anti-PID (Potential Induced Degradation) Potting.
6.Special Power Supply Applications
Medical Power Supply: Potting adhesive must meet biocompatibility (such as ISO 10993 standards).
Military Power Supply: Potting must pass high and low temperature (-40°C to 125°C) and salt spray tests.
Advantages of Fully Automatic Glue Potting Machines
High Precision: A metering pump controls the mixing ratio (e.g., 1:1, 2:1) with an error of ≤1%.
Automation: Combined with a vision system or robotic arm, it enables assembly line operations (e.g., automotive power supply production lines).
Fast Curing: Supports UV adhesives and low-temperature curing adhesives (80°C/10 minutes).
Complex Processes: Capable of handling requirements such as underfill and dam-and-fill.
