Fully automatic process control for vacuum resin casting systems

Abstract

For decades, the electric equipment and electronics industries are increasingly utilizing casting resins as substitutes for traditional insulating materials. The excellent insulating properties of vacuum-processed resins permits the manufacture of compact, light weight and maintenance free products. Casting resins are used for potting, encapsulating, molding, and for sealing of various types of components. The major types of curable casting resins include: epoxy, polyurethane, silicone, and polyester. These materials generate no by-products and cure free of voids. Highly abrasive filler materials in the resin and hardener components give excellent electrical and mechanical behavior, but also create difficulties for the life time of machine parts, and make a process control more complicated.
