• Diverse Steel Grades and Sizes Available:

Jindinghao offers one of the most versatile portfolios in the precision tube industry, catering to diverse engineering demands across sectors like construction machinery, automotive, oil & gas, and textile equipment. Our precision cold-drawn tubes are available in multiple steel grades—including 20#, 45#, 16Mn, 25Mn, and 27SiMn—with sizes ranging from 60mm to 299mm in diameter and customizable wall thicknesses. These tubes are delivered in various states: annealed, stress-relieved annealed, normalized, bright annealed, and cold-drawn, allowing clients to select the optimal mechanical properties for their application. For instance, our precision honing tubes are widely used in high-pressure hydraulic cylinder barrels where dimensional stability and surface finish are critical. Similarly, our precision rolled tubes serve as core components in motor housings and transmission shafts due to their excellent concentricity and uniformity. In another real-world case, a major Chinese construction equipment manufacturer (XuGong partner) adopted our non-standard hydraulic cylinder bodies (250–960mm in length) made from forged 45# steel, which significantly reduced assembly time and improved machine longevity. With full in-house production—from forging to finishing—we ensure consistent quality while reducing lead times by up to 30%. Whether you need fixed-length flat rods, machined piston rods (45# or 2Cr13), or custom-bored cylinders, Jindinghao delivers tailored solutions with proven performance in demanding environments.

--- Advanced Research and Development ---

• Continuous Product Innovation:

Innovation drives Jindinghao’s growth. With an annual R&D investment of 10 million yuan, we continuously develop new products and refine existing ones to meet evolving industrial needs. One notable achievement is our patented flange design (Patent Name: A Flange That Is Easy to Locate; Date: 2025.08.13), which simplifies assembly in hydraulic systems and reduces installation errors by up to 40%. This innovation was directly applied in a series of export orders to Eastern Europe, where clients reported faster maintenance cycles and fewer leaks. Beyond patents, we conduct regular material science research, optimizing heat treatment processes to enhance hardness (HRC60+) and wear resistance without compromising ductility. Our team also develops customized solutions—for example, a low-friction coating for piston rods used in high-speed glass machinery, improving efficiency by 18% compared to standard models. Furthermore, we collaborate closely with partners like Zhonglian and XuGong to co-develop next-generation components that align with Industry 4.0 standards. Our ability to innovate isn’t limited to products—it extends to production methods. By integrating smart monitoring systems into our cold drawing and honing lines, we achieve real-time quality tracking and predictive maintenance, minimizing downtime and waste. As a result, Jindinghao consistently launches 3–5 new product variants each year, ensuring we stay ahead of market trends and deliver future-ready solutions.
