The hydroforming component features lightweight design, exceptional product quality, flexible product design, and a simplified process. Characterized by near-net forming and green manufacturing, it has been widely adopted within the automotive lightweight sector. Through effective section design and wall thickness optimization, numerous auto parts can be shaped into a single, complex integral component via the hydroforming of standard tubes.

This approach is significantly superior to traditional stamping and welding methods, offering enhanced product quality and production efficiency. Most hydroforming processes require only a punch (or hydroforming punch) matching the shape of the part, while the rubber diaphragm on the hydroforming machine serves the function of the traditional die. Consequently, die costs are reduced by approximately 50% compared to traditional dies. Unlike traditional stamping, which involves multiple stages, hydroforming forms the same part in just a single step.

Compared with stamping welding parts, the distinct advantages of pipe hydroforming include:

• Material Savings & Weight Reduction: General structural parts can be reduced by 20% to 30%, and shaft parts can be reduced by 30% to 50%. For instance, a typical stamping car subframe weighs 12kg, whereas an internal high-pressure formed subframe weighs only 7 to 9kg, achieving a 34% weight reduction. Similarly, a radiator support is reduced from 16.5kg (stamping) to 11.5kg (hydroforming), representing a 24% weight reduction.
• Reduced Processing: Significantly decreases subsequent machining operations and welding workloads.
• Enhanced Structural Strength: Boosts the strength and stiffness of components, and increases fatigue strength due to the reduction of solder joints.
• High Material Utilization: Achieves a material utilization rate of 95% to 98% compared to traditional welded components.
• Cost Efficiency: Decreases total production and mold costs by approximately 30%.

Hydroforming equipment is suitable for manufacturing complex-shaped, section hollow components across a variety of industries, including aerospace, nuclear power, petrochemical, drinking water systems, piping systems, automotive, and bicycle manufacturing.

Within the automotive field, the primary components produced include automobile body support frames, auxiliary frames (subframes), chassis parts, engine supports, intake and exhaust system pipe fittings, camshafts, and other structural parts.
