On January 13, 2022, Jinhua Machinery Group Company delivered the DN3600 cold hydrogenation reactor manufactured for Inner Mongolia Dongli Photovoltaic Electronics Co., Ltd. This equipment is the core device for Inner Mongolia Dongli Photovoltaic Electronics Co., Ltd. to produce 20,000 tons of high-purity polysilicon per year. The equipment has a total length of 21.6 meters, a net weight of 165 tons, and a diameter of 3.6 meters; it is made of thick-walled stainless steel SA240, 316, as well as the nickel-based alloy N08810.
In March, Jinxi Chemical Machinery Group Co., Ltd. overcame the impact of the pandemic by reasonably planning construction schedules and organizing production in a scientific manner, ensuring that the products under production were completed on time. By the end of the month, projects such as Lihuiyi, Minxiang Chemical, and China Tianchen had been successfully completed, achieving a total output value of over 30 million yuan. In the face of the challenges posed by the pandemic, various departments within the company worked closely together to establish a \"green channel.\" When the arrival of raw materials was delayed, the production system adjusted its plans flexibly, taking into account both the timing of material delivery and the product delivery dates, so as to ensure that the plans aligned with the actual situation of material availability and to maintain smooth coordination between different stages of production. The quality management department has intensified quality inspections, and all production units strictly enforce the quality reward and penalty system to continuously improve the rate of first-time pass rates, thereby promoting efficiency through high quality. During construction, various production units continuously innovate their methods to improve efficiency; party members and cadres lead everyone in working overtime to overcome production bottlenecks. While ensuring the orderly progress of various projects, Jinhua Machinery also meets the urgent needs of special customers based on actual circumstances. Upon learning that the major maintenance schedule at Tianjin Bohua had been advanced for certain reasons, the company promptly stepped up its production efforts to complete the manufacturing of the low-pressure waste boiler tubes required in a timely manner. In March, Jinxi Chemical Machinery Group Co., Ltd. completed the manufacturing of 34 container units, 4 turbine units, as well as related spare parts, thus successfully fulfilling its monthly production targets.

January 18, 2019, will be a day that the more than 1,700 employees of the Lao Jinxi Chemical Machinery Factory will always remember, as it was the day they were all laid off. Apart from more than 400 employees and cadres who can continue to compete for positions, the rest of the staff will leave the company completely. After two restructuring processes in 2000 and 2009, as well as this recent bankruptcy reorganization, the former Jinxi Chemical Machinery Factory leaves behind only sighs of regret and enduring memories.
Aging machine! The operation site needs improvement!
