AI Technical Summary

Technical Problem

Existing mold pressing molding apparatuses struggle to accurately measure the transfer progression state of a molding material conforming to a mold surface, leading to potential untransferred portions and molding defects, and cannot detect these issues until the molding process is complete.

Method used

A mold press type molding apparatus equipped with probes for transmitting and receiving acoustic signals at multiple radial positions between the outer edge and center of the molding surface to monitor the transfer progress by using ultrasonic waves.

Benefits of technology

Enables real-time monitoring of the transfer progress, allowing for early detection of untransferred portions and enabling feedback control to maintain high surface accuracy and prevent defects during the molding process.
