AI Technical Summary

Technical Problem

There are local discharge problems caused by bubble residues in the traditional epoxy resin vacuum casting process, and the prior art cannot effectively remove micro bubbles inside the coil and bubbles in the narrow-slit structure of the deep cavity, affecting the reliability and production efficiency of the equipment.

Method used

High-precision vacuum and intelligent bubble removal are adopted to coordinate control. Through cascade preheating and laminar flow casting technology, the resin is injected into the mold in a laminar flow state. Combined with secondary vacuum extraction or pressurized bubble removal treatment, micro bubbles are completely eliminated and the potential for equipment operation and discharge.

Benefits of technology

Significantly shorten the manufacturing cycle, improve product quality and production efficiency, reduce defect rate and energy consumption, optimize manufacturing costs, and improve industrial economic benefits.
