Company Overview
- Chengdu Zhengda Chemical Machinery Co., Ltd. (formerly known as Chengdu Zhengda Heat-Resistant Technology Co., Ltd.) was established in 1993, with its headquarters located in Qingbaijiang District, Chengdu City, Sichuan Province. In 2010, the factory was relocated from Datong Town, Qingbaijiang District, Chengdu, to High-Tech Industrial Park in Guanghan City, Deyang, Sichuan Province.
- The Company specializes in the manufacturing of special high-temperature alloy equipment components for petrochemical systems, custom machining of non-standard parts based on customer drawings, as well as the import and export of goods and technologies.
- It is strictly managed with a robust quality management system, advanced equipment, and is equipped with automatic temperature-controlled high-temperature trolley furnaces and box furnaces capable of reaching 1200°C to meet the heat treatment needs of various special materials. High-precision machining centers and CNC lathes ensure the ability to produce complex, high-precision petrochemical equipment components. The Company obtained ISO9001 certification in 2002, ISO45001 and ISO14001 certifications in 2023, and a 3A credit rating certification (including seven certifications in one system) in 2023.
