Manufacturing Capacity Built for Stable Bulk Supply
As your long-term partner, we understand that scale is only the foundation—what matters more to you is consistent and stable delivery over time. Yueding operates a manufacturing base of over 20,000 m², with a layout specifically optimized for the continuous production of exhaust flex pipes, metal bellows, and related clamp fasteners. This setup is designed to support both standardized bulk orders and complex custom requirements in global exhaust flexible connection applications.
For stainless steel flexible pipe products, production is supported by multiple flexible lines and grouped processing equipment working in coordination, covering the full process from tube cutting to bellows forming, braiding, and welding. Compared with a single long production line, this arrangement allows your custom requirements and large-volume orders to be handled in parallel with greater flexibility. Semi-automatic hydraulic forming machines and dedicated CNC stamping equipment help ensure consistent corrugation height and pitch during forming, improving flexibility, fatigue resistance, and structural stability. Currently, monthly output of bellows products reaches around 350,000 pieces, providing solid support for your long-term supply needs.
For various clamps and related fasteners, production is supported by multiple automated and semi-automated equipment groups. Automation is mainly applied to key forming and assembly stages, with a monthly output of approximately 2.01 to 5 million pieces. This ensures that your high-volume orders are delivered with consistent structure and reliable assembly matching. In clamp production, highly integrated automated equipment combines stamping, forming, and welding into a single process unit. While maintaining dimensional consistency and welding stability, this also improves output efficiency per line and reduces reliance on manual operation, helping maintain control over both product quality and production rhythm in long-term supply.
Yueding has a team of over 200 employees, including more than ten experienced engineers who are continuously involved in product structure design, material selection, and process optimization. An in-house testing laboratory conducts fatigue, pressure, sealing, and corrosion resistance tests on exhaust flex pipes and metal bellows, verifying product performance under different working conditions.
Based on ongoing OEM/ODM cooperation, you can move from drawing-based customization to small-batch validation and then into stable mass production. The focus is to provide repeatable manufacturing capability and consistent long-term supply, rather than one-time custom delivery.

Mass Production Capacity: Our front-line team is a solid support for production and delivery, with the resilience to respond quickly to large-scale orders.
Strict Quality Control: All staff receive training for the zero-defect goal of automated production lines, ensuring each product has traceable stability.
Your Success, Our Mission: Behind every order of yours is our commitment to excellence and win-win cooperation.
Consistency You Can Trace, Quality You Can Trust
Full-Process Production Control You Can Rely On
In your bulk sourcing, stability starts from the production process itself. From raw material intake to final packing, each step follows defined process controls and checkpoints.
Key stages such as tube forming, bellows corrugation, braid assembly, welding, and clamp forming are managed under consistent production standards. Raw materials like stainless steel strips and tubes are verified and tracked by batch, helping you maintain stable input quality across orders.
This structure helps you reduce variation risks and ensures that what you approve in samples can be repeated in mass production.
Standards and Documentation for Consistent Output
Your orders are produced under recognized industry standards, including ISO9001, ISO14001, and IATF16949 frameworks. For metal bellows and expansion components, production aligns with GB/T12777 and EJMA requirements.
More importantly, these standards are translated into internal process documents and operating procedures. This means your products are not dependent on individual workers, but follow unified instructions across different batches and production cycles.
For you, this ensures consistency when scaling from initial orders to long-term supply.
Structured Inspection Across Key Stages
To support your quality requirements, inspection is built into multiple stages of production. Each order goes through self-check, cross-check, and dedicated inspection before delivery.
An independent inspection team monitors critical steps and finished products, ensuring that quality control does not rely on individual experience, but on repeatable inspection methods.
This approach helps you maintain traceability and reduces the risk of unexpected deviations in bulk orders.
Support Beyond Delivery for Long-Term Use
Your requirements often go beyond manufacturing. Based on your application conditions, you can receive supporting documents such as inspection reports and technical data.
You can also get practical support in product selection, pipeline matching, and installation considerations. For products in operation, defined warranty terms and response procedures help you handle issues efficiently.
Even beyond warranty, technical support and spare parts supply remain available, helping you keep systems running reliably over time.
Practical OEM/ODM Support for Your Custom Projects
You can integrate customization directly into your sourcing process. Based on your drawings, samples, or application requirements, Yueding supports structure confirmation, material selection, and production feasibility from the start.
For exhaust flex pipes, bellows, and related clamps, you are not limited to build-to-print. You can also receive practical suggestions on corrugation design, braid type, welding method, and connection form, all aligned with real production conditions.
You can move from sample testing to stable mass production step by step. With controlled processes and in-house inspection, your custom products maintain consistency across batches.
Our focus is simple: helping you turn designs into stable, repeatable production.
Certified Performance Testing & Quality Validation
Testing Laboratory
Measurement Instrumentation
The relevant stainless steel raw materials undergo strict specification review and batch management upon entering the factory to confirm that chemical composition, thickness, and mechanical properties meet requirements. We mainly use a spectrometer to analyze chemical composition, and some materials are also checked with a two-dimensional measuring instrument for dimensional accuracy. This ensures that each batch of raw materials meets production standards in mechanical performance and structural consistency.
Regarding quality control in the production process, Yueding mainly sets key control points for forming, stamping, welding, and other processes, combined with regular inspections to ensure that stamping shape, welding strength, and crimping torque are all within the design range. We also pay great attention to the quality inspection process of finished products. For related clamps, we use Atlas torque wrenches to test clamping torque, cupping testing machines to test tear resistance, salt spray testing machines for corrosion resistance, and air tightness testing instruments to check sealing after installation, etc. For bellows, the focus is on testing corrugation stiffness, flexibility, pressure resistance, and fatigue performance, and salt spray tests and chemical composition analysis are carried out if necessary to confirm corrosion resistance and high-temperature performance.
