Our core advantages lie in our accumulated experience of 20 years focusing on hydraulic systems, hydraulic pipelines, and engine parts, and our familiarity with the adaptation needs and compliance standards of markets in Europe, America, and Southeast Asia; Independent Quality Control: Our own workshop enables full-process control from raw material processing to finished product assembly, avoiding the quality fluctuations of OEM models; Market Validation: Our products have been stably supplied to over 30 regions domestically and internationally, serving over 5000 repair shops and equipment suppliers, with a repurchase rate of 85%.
We are an integrated industrial and trading company specializing in hydraulic components. We have a core team focused on the R&D, production, and global trade of hydraulic system components for excavators, bulldozers, loaders, etc. Please feel free to contact us with any questions.
Providing any of the following information will complete an accurate compatibility check: ① Excavator brand + model + serial number ② Original part number (e.g., the number engraved on the nameplate)
We support compliant payment methods for independent websites, ensuring transaction security: Offline customized payment: For wire transfer (T/T) or Western Union, please contact our dedicated customer service representative to obtain your account information. We will provide payment vouchers simultaneously.
All hydraulic components come with a 6-month full machine warranty, covering performance failures caused by non-human factors (such as seal failure, accuracy deviations, etc.).
Quality control is implemented throughout the entire production chain, achieving "zero non-conforming products leaving the warehouse": A triple inspection mechanism: raw material incoming inspection (such as hardness testing of hydraulic valve materials), and random sampling during production (10% of each batch undergoing pressure testing).
We are happy to provide small-batch trial production services to verify product compatibility. We have flexible production lines capable of efficiently handling multi-variety orders. Once the trial order is successful, we will incorporate your product technical data into our production management system to ensure the quality stability and delivery reliability of subsequent large-scale supplies.
Yes. We have hydraulic system integration capabilities. From schematic design, component selection, valve block design and manufacturing to tank and piping manufacturing and system assembly testing, we can provide one-stop hydraulic power unit or system solutions to help you simplify your supply chain and optimize system performance.
As a source manufacturer, we possess end-to-end control capabilities, from design and R&D, raw material procurement, precision machining to assembly and testing. This allows us to offer more competitive costs and prices, achieve rapid and flexible customized production, and ensure full-process traceability and quality assurance for our products. You are not just buying a product, but acquiring a complete solution based on deep technological understanding.
We implement end-to-end quality control from raw material warehousing to finished product delivery. Key processes include: raw material spectral analysis, coordinate measuring machine (CMM) measurement of core components after CNC machining, cleanliness control during assembly, and final functional and durability testing. Each process has rigorous inspection records.
We would be very happy to welcome such offers. We maintain long-term partnerships with many large domestic and international repair companies and equipment remanufacturing plants. We can offer tiered bulk discounts and provide OEM/ODM manufacturing services tailored to your brand requirements.
