Hot Bushing Insertion

This machine uses a vibratory bowl feeder to feed knurled brass bushings down 8 chutes. The bushings are accumulated in the chutes and heated to 500+ degrees F. A thermoplastic part is clamped in the fixture. Hydraulic cylinders press the hot bushings into the part. The bushings melt their way into the part. This ensures the bushings are rigidly secured once the material cures around the knurls in the bushings. 8 bushings are installed simultaneously.
