en.Wedoany.com Reported - China National Machinery Industry Corporation (Sinomach) recently delivered a batch of major technical equipment in the high-end equipment sector, including a 1000mm stainless steel precision strip twenty-high cold rolling mill, a 4MY-4A cotton picker, and a wide-width polyethylene/polypropylene bicomponent spunbond nonwoven production line. These pieces of equipment were developed respectively by Sinomach's subsidiaries: China National Heavy Machinery Research Institute Co., Ltd. (China Heavy Machinery Research Institute), Chinese Academy of Agricultural Mechanization Sciences (CAAMS), and China Hengtian Group Co., Ltd. (Hengtian Group), marking significant progress in precision stainless steel rolling, intelligent cotton picking, and nonwoven material production.
Founded in 1997 and headquartered in Beijing, Sinomach is a key state-owned enterprise directly managed by the central government of China. Its business covers areas such as R&D and manufacturing of machinery equipment, engineering contracting, and trade services. It owns several core subsidiaries, including China Heavy Machinery Research Institute, CAAMS, and Hengtian Group.
According to Sinomach, the 1000mm stainless steel precision strip twenty-high cold rolling mill, designed and integrated by China Heavy Machinery Research Institute, has successfully passed its hot load test run and commenced production. The mill innovatively integrates multiple systems such as automatic gauge control and multi-functional shape control, achieving high-precision stable rolling with a minimum thickness of 0.1mm and a maximum speed of 600 meters per minute. The product's thickness tolerance and strip shape quality have been recognized by users. This equipment provides support for users to expand high-end stainless steel deep processing operations.
Modern Agricultural Equipment Technology Co., Ltd., a subsidiary of CAAMS, upgraded the 4MY-4A cotton picker. After completing assembly and performance testing at its production base in Gu'an, Hebei Province, the first batch of products has officially rolled off the production line and been shipped. This series of cotton pickers is equipped with an intelligent harvesting control system, enabling integrated harvesting and baling operations, with operational efficiency and picking accuracy reaching advanced domestic levels in China. Additionally, the cab and integrated control console have been fully upgraded to enhance operational comfort and overall machine efficiency.
The wide-width polyethylene/polypropylene bicomponent spunbond nonwoven production line, independently developed and constructed by Hongda Research Institute Co., Ltd. of Hengtian Group, has completed full-line joint commissioning and trial production. After relevant testing and process validation, all product performance indicators have fully met standards. Under wide-width production conditions, the product exhibits excellent uniformity, softness, and usability, meeting the stringent requirements of high-end hygiene care material applications, providing more material solutions for the global high-end market.
The centralized delivery of these advanced pieces of equipment demonstrates Sinomach's comprehensive strength in the independent R&D and manufacturing of high-end equipment, helping to drive technological upgrades and equipment self-sufficiency in related industries in China.
