Company Profile
Linyi Haoyu Machinery Co., Ltd. is a modern specialized manufacturer integrating R&D, production, processing, and sales. With more than a decade of deep expertise in core components such as shafts and hydraulic cylinders, the company focuses on delivering high-quality supporting products for the agricultural equipment, construction machinery, commercial vehicle, and export custom-order industries. Backed by exquisite manufacturing craftsmanship and consistently stable product quality, it has become a core strategic partner supplier for numerous large industrial enterprises across China.
Founded in 2008, the company is located in the North Industrial Park of Yishui County, Shandong Province — an area with an excellent environment and convenient transportation. The plant covers a total area of 53,000 square meters, with a building area of 30,000 square meters, and its large-scale layout provides a solid foundation for batch production and efficient delivery. Through more than a decade of steady development, the company has established a mature production system and a well-structured talent framework. It currently employs over 150 staff members, including core teams dedicated to technical R&D, production management, quality inspection, and market service, giving it strong in-house manufacturing and innovative development capabilities.
In terms of production facilities, the company is fully equipped with standardized professional workshops, including an automated machining workshop, a heat treatment workshop, a welding workshop, and an oxidation treatment workshop. It achieves full in-house process control — from independent R&D and product machining to surface treatment, final assembly, and an automated painting line — enabling effective control over product precision and production lead times. The company’s main products span two core series: first, a full range of precision shaft products, including drive shafts, spline shafts, and axle shafts for agricultural equipment, construction machinery, and specialized automotive applications; and second, a complete range of hydraulic cylinders, covering dump truck cylinders, construction machinery cylinders, sanitation vehicle cylinders, agricultural equipment cylinders, and industrial and mining hydraulic products. These products are widely compatible with machinery across multiple sectors, with a comprehensive annual production capacity of 500,000 units/sets, capable of meeting large-batch, standardized, and customized production orders.
Thanks to its outstanding product quality and reliable market reputation, the company has established long-term, stable supporting partnerships with leading domestic industry enterprises, including Weichai Lovol, Changzhou Dongfeng Group, Zoomlion, Wuzheng Group, Deutz-Fahr, CLAAS, World Group, Shifeng Group, Lingong Group, Jinyi Group, and Zhejiang Haitian Machinery. Its products cover markets across China and have earned unanimous recognition from customers for their high adaptability and durability.
Quality is the foundation of the business. Since its inception, the company has embedded quality control throughout the entire production process and established a systematic, standardized quality management system. It has successively passed the ISO9001 Quality Management System certification and the IATF 16949:2016 Automotive Quality Management System certification, operating production operations to internationally high standards. In practice, the company builds its quality defense across three dimensions — hardware equipment upgrades, production process optimization, and internal management standardization — and has enacted a stringent full-process quality control system. From strictly vetting suppliers at the raw material procurement source and implementing 100% incoming inspection, to batch-, category-, and drawing-based control during production, every stage — semi-finished machining, final assembly, and outgoing inspection — is subject to comprehensive, real-time monitoring. All products strictly comply with national and industry standards, ensuring that no non-conforming product leaves the factory, and guaranteeing the precision, stability, and service life of every item.
Dedicated to its industry for over a decade, the company has always upheld its core business philosophy of “Quality First, Customer Foremost” and its corporate spirit of “Integrity, Pragmatism, Pioneering, and Enterprise,” focusing deeply on the precision machinery manufacturing segment. Through the continuous introduction of advanced production equipment, optimization of production processes, upgrades to its management model, and cultivation of professional technical talent, the company’s production scale, product quality, and market competitiveness have kept improving, with its market share growing steadily.
Looking ahead, the company will continue to stay rooted in its precision manufacturing main business, remain true to its quality-first commitment, and persist in innovation-driven development. It will keep optimizing its product and service systems to repay both new and existing customers with superior products and more efficient services, and strive to build itself into a highly reputable and capable professional manufacturing brand in China’s shaft and hydraulic cylinder sector.
