Kunshan Chengqian Machinery Co., Ltd. (Chengqian Group)

Kunshan Chengqian Machinery Co., Ltd., operating as Chengqian Group, is a Chinese high-tech enterprise specialising in the design, manufacture, sales, and service of rubber and plastic processing machinery — headquartered in Qingpu, Shanghai, with R&D and production bases across Jiangsu Province operating through five subsidiaries. The group's product portfolio spans five major machinery categories: rubber and plastic mixing production lines, calendaring production lines, pelletizing and granulating lines, cold and hot feed rubber gear pump strainer systems, and rubber preformer and VibraCool cooling lines — providing complete upstream production chain coverage for manufacturers of rubber and plastic components across automotive, general rubber goods, footwear, sports and leisure, agriculture, and other industrial sectors. CE certified across six product lines including kneader mixers, open mills, rubber preformers, rubber strainer extruders, and rubber cooling conveyors, and additionally holding EN 12100:2010 certification for its spiral cooling conveyor and ECM certification for its rubber precision preformer, Chengqian Group combines rigorous international quality certification with a clear product development philosophy oriented toward intelligence, efficiency, and digitalization. Equipment has been exported to Brazil, Thailand, India, the United States, Russia, South Korea, and beyond — with each customer and product maintained in comprehensive technical documentation to support continuous after-sales service throughout the equipment lifecycle, including a standard 12-month warranty and ongoing discounted technical support post-warranty.

Indonesia's rubber processing and rubber component manufacturing industry is one of the country's most significant industrial sectors — a natural consequence of Indonesia being the world's second-largest natural rubber producer, with large plantation estates across Sumatra, Kalimantan, and Java feeding a domestic rubber processing chain that includes tyre manufacturers, automotive rubber component suppliers, industrial seals and gasket producers, footwear manufacturers, and agricultural equipment parts suppliers. Indonesian rubber product manufacturers investing in upstream processing capacity — preforming machines for automotive seals and gaskets, strainers and extruders for compound purification, kneader mixers and open mills for rubber compound preparation, cooling conveyors for preform handling, and pelletizers for recycled rubber and masterbatch production — represent the primary buyer profile for Chengqian Group's machinery in the Indonesian market. As Indonesian automotive component manufacturers supplying Hyundai's Cikarang plant, Astra-Toyota joint ventures, and Mitsubishi's Bekasi operations increasingly invest in domestic rubber compound processing capacity to reduce import dependency, demand for CE-certified, export-proven Chinese rubber machinery with full technical support represents a growing and accessible market segment for Chengqian's product range.
