Our Development Milestones

2007
Foundation Stage
The predecessor Hebei Runtong Auto Parts Co., Ltd. was founded in Mainland Village, Ningjin County, Xingtai, Hebei Province, starting production of automotive heat dissipation products.
2010
Standardization & Capacity Expansion
Expanded factory construction area by 13,000 ㎡ with fixed assets exceeding RMB 12.6 million. Took the lead in the industry to obtain ISO 9001:2008 International Quality Management System Certification, laying standardized quality control foundations. Main product line shifted to automotive radiators, establishing stable domestic automotive supporting supply chains.
2015
Brand Upgrade & Hydraulic Heat Dissipation Breakthrough
Rebranded as Hebei Keyuan Technology Co., Ltd. to complete organizational division optimization and expand industrial boundaries. Launched self-developed ultra-high pressure AH series durable air coolers, targeting heat dissipation pain points of large-flow, high-pulse heavy-duty hydraulic systems.
2017
Core Hydraulic Component Strategic Layout
Formally launched the Hydraulic Components Division to prioritize core technology R&D and product iteration. Three flagship core products – hydraulic multi-way valves, hydraulic motors and gear pumps – were officially rolled out. Supported by deep technical research and innovative process iteration, we began supplying high-durability, high-efficiency hydraulic solutions to global industrial clients.
2019
Full-Link Fluid Protection Matrix Layout
Responding to surging global demand for hydraulic system reliability in engineering machinery and new energy equipment, we built a three-dimensional protection product system covering hydraulic filtration, real-time monitoring and fluid purification. New product lines including hydraulic filters, liquid level gauges and air filters were launched to realize full-cycle hydraulic fluid management.
2020
Global Layout & Shanghai Intelligent Hydraulic Base Launch
Founded Shanghai Shangjia Intelligence Control Hydraulic Co., Ltd., leveraging the Yangtze River Delta’s logistics, talent and export advantages to focus on intelligent hydraulic control R&D and overseas market expansion. Built international standard testing laboratories and digital global service systems. Core products (multi-way valves, gear pumps) passed key EU & North American market certification audits. Our hydraulic solutions are now exported to more than 50 countries worldwide.
2022
Deepened Hydraulic Component R&D System
Further invested in the Hydraulic Components Division to accelerate core technology breakthrough and product performance upgrading. We optimized three core product lines (multi-way valves, hydraulic motors, gear pumps) to deliver longer service life and higher overall system efficiency for global end users.
