Secondary Potting Machine Production Line | Two-stage AB Glue Potting System
Our automatic secondary potting machine production line is specially developed for two-stage electronic encapsulation. After the first layer of potting compound is fully cured, this continuous conveyor line completes the second-layer AB glue metering, mixing, dispensing and vacuum potting. It is widely adopted for high-voltage transformers, power modules and LED drivers that require double-layer insulation protection. The whole line realizes inline continuous secondary encapsulation, greatly improving production consistency and throughput for mass manufacturing.
Our secondary potting machine production line is designed for two-stage electronic encapsulation. After the first layer of epoxy resin is cured, this automatic line performs secondary AB glue metering, mixing, dispensing and vacuum potting. It realizes continuous conveyor production for high-low voltage insulation of transformers, power modules and LED drivers, ensuring stable encapsulation quality for mass manufacturing.

FAQ
Q1: What is secondary potting?
A: Secondary potting means applying the second layer of resin after the first potting layer is fully cured, usually for high voltage insulation protection of transformers and power modules.
Q2: Can this secondary potting line work with vacuum degassing?
A: Yes, vacuum potting station is optional to remove air bubbles during secondary glue dispensing.
Q3: Can we connect this line with your primary potting machine?
A: Absolutely. Our secondary potting line can be seamlessly integrated with the first-stage potting production line for fully automatic two-stage encapsulation.
Q4: What materials does the secondary potting system support?
A: It works with two-component epoxy resin, polyurethane PU and silicone AB glue.
