Jiangsu Baoshi Heat resistant Technology Development Co., Ltd. is the first refractory material production enterprise in Dongtai. The company was founded in October 1975. Through nearly 50 years of accumulated innovation, the company has acquired proprietary technology and has won honors such as "Comprehensive Quality Management Standard Enterprise" from the Ministry of Agriculture, "Star Enterprise" from Jiangsu Province, and National High tech Enterprise multiple times.
At present, we have two sets of automated batching systems, five extrusion molding production lines, five cutting and processing production lines, two automatic temperature controlled high-temperature tunnel kilns, one high-temperature shuttle kiln, three press molding production lines, and two automatic batching amorphous refractory material production lines, with an annual output of 20000 tons of various refractory materials.
The enterprise has passed the IS09001 quality management system certification and safety production standardization certification, providing customers with high-quality and reliable products. We have offices in ceramic production bases such as Foshan in Guangdong, Jinjiang in Fujian, Gao'an in Jiangxi, Linyi and Zibo in Shandong, and Faku in Liaoning, providing high-quality and convenient services to our customers at any time.
