Industry & Occupation
Classification
Summary
This occupation involves blending clay mixtures for roof tile bases, adjusting moisture content, and manufacturing raw materials with appropriate moldability and strength.
Description
Roof tile clay preparation workers specialize in raw material blending and moisture content adjustment in the initial stage of roof tile manufacturing. They mainly weigh raw materials such as clay, silica sand, and feldspar in predetermined ratios, and process them into slurry or granular form using kneading machines, crushers, and degassing equipment. During the process, they measure particle size and moisture content, repeatedly make fine adjustments to the blending ratios to ensure moldability, strength, and dimensional stability after firing. They collaborate with quality inspection rooms to conduct sample tests, manage to prevent substandard raw materials from mixing in, and proceed with work while complying with safety and health standards.
Future Outlook
Although the traditional Japanese tile industry is showing a gradual decline in demand, there is continued demand for restoration of traditional buildings and in the luxury housing market. The introduction of automation and IoT technologies is progressing, with expectations for labor savings and quality stabilization, while challenges include technology succession and addressing labor shortages.
