AI Technical Summary

Technical Problem

Conventional methods face difficulties in accurately positioning crystalline glass materials of non-plate shapes, such as rods or blocks, on setters during the manufacturing of crystallized glass articles, leading to issues like misalignment and inadequate heat treatment.

Method used

A setter made of heat-resistant crystallized glass with an elongated groove is used, featuring a bottom surface and side surfaces to precisely position the crystalline glass material, with specific height and width ratios to ensure proper heat treatment and prevent deformation.

Benefits of technology

The method enables accurate positioning and efficient heat treatment of crystalline glass materials, preventing warping and misalignment, allowing for high-quality crystallized glass article production.
