Multi-Cavity Stamped Parts

XIAYI Multi-Cavity Stamped Parts are integrated automotive structural components designed for shock absorber systems, damping support structures and vibration control applications. Through one-time multi-cavity synchronous forming technology, multiple functional areas including damping flow cavities, positioning structures and reinforcement sections are formed into a single component, achieving high structural consistency and reliable assembly performance.

Compared with traditional multi-piece assembled structures, XIAYI eliminates secondary welding and assembly processes through integrated forming technology. The optimized cavity layout improves stress distribution, dimensional accuracy and vibration resistance, making the products suitable for passenger vehicles, new energy vehicles, SUVs, commercial vehicles and outdoor machinery applications.

Integrated Cavity Design

Automotive shock absorber structural components often combine multiple functions, including damping channel guidance, positioning support and reinforcement. Traditional split structures require separate manufacturing and secondary assembly, which may create assembly gaps and dimensional accumulation.

XIAYI adopts integrated multi-cavity forming technology to combine different functional areas into one component. This design improves structural coordination and reduces variation caused by multiple assembly processes.

Multiple Functions in One Component

The cavity layout is designed according to shock absorber system requirements, integrating damping flow areas, positioning structures and reinforcement sections.

The integrated design allows different functional areas to work together with consistent stress distribution during vehicle operation.

Reduced Assembly Deviation

Traditional assembled parts may generate cumulative errors from multiple components and welding processes.

XIAYI Multi-Cavity Stamped Parts use one-time synchronous forming to control cavity positions, hole locations and structural dimensions within the same manufacturing process.

High Ductility Steel Material

The material selection directly affects forming quality, impact resistance and long-term durability of multi-functional structural components.

XIAYI selects high-ductility steel materials according to different application conditions to achieve stable forming performance and mechanical reliability.

ST14 Deep Drawing Steel

The products use ST14 high-ductility cold rolled steel with elongation ≥40% and controlled internal inclusion grade within Grade 2.

The uniform metallographic structure provides excellent tensile toughness and impact resistance, supporting complex multi-cavity forming without cracks or local deformation.

Application-Based Material Matching

XIAYI provides different material solutions according to vehicle type and working environment.

Thicker plate versions are suitable for coastal, mountain and heavy-load applications, while lightweight versions are designed for urban passenger vehicle applications.

Precision Forming Process

The accuracy of each cavity directly influences shock absorber assembly and damping performance. XIAYI uses self-developed multi-station synchronous forming processes to maintain stable cavity dimensions during mass production.

One-Time Synchronous Forming

Multiple cavities, positioning holes and reinforcement structures are formed simultaneously without secondary welding or assembly.

The process controls cavity position, opening size and wall thickness consistency, with wall thickness tolerance maintained within ±0.02mm.

Stress Relief Treatment

After forming, components undergo 4-hour constant-temperature aging treatment at 120℃ to release residual stamping stress.

Secondary three-dimensional calibration ensures stable cavity geometry and reduces deformation during long-term vibration operation.

Vibration and Durability Performance

Shock absorber structural parts operate under continuous vibration, impact loads and changing road conditions. Stable structural coordination is essential for maintaining suspension performance.

Uniform Stress Distribution

The integrated cavity structure avoids uneven stress caused by separate component connections.

This helps improve resistance against fatigue, impact deformation and long-term vibration loads.

NVH Performance Support

Small assembly gaps in traditional structures may contribute to abnormal chassis noise.

The seamless integrated structure reduces connection gaps and supports improved vehicle quietness and driving comfort.

Surface Protection Capability

Vehicle structural parts may face humidity, salt fog and road corrosion during operation. XIAYI provides different zinc coating solutions according to environmental requirements.

Heavy-Duty Corrosion Protection

Heavy-duty versions adopt 12~14μm blue-white zinc passivation coating and pass 500-hour neutral salt spray testing without rust pitting.

The coating protects cavity surfaces and structural areas from coastal salt fog and deicing salt corrosion.

Standard Environmental Protection

Standard versions use 10μm zinc coating with 420-hour salt spray resistance.

The surface treatment provides reliable corrosion resistance for general vehicle operating environments.

Quality Inspection System

XIAYI applies full-process quality control from raw material selection to finished product inspection.

PFMEA Process Management

The PFMEA system covers material inspection, cavity forming, stress aging, deburring cleaning and surface treatment.

Potential risks including cavity deformation, wall thickness variation and dimensional deviation are controlled before mass production.

3D Dimensional Inspection

Equipped with 6-channel 3D optical scanning equipment, XIAYI performs 100% dimensional inspection for finished products.

The production process achieves batch stability CPK≥1.67 and factory defect rate lower than 0.1%.

Application Cases

New Energy Vehicle NVH Optimization Case

New energy vehicles have strict requirements for chassis quietness and damping consistency.

A domestic new energy vehicle OEM adopted XIAYI Multi-Cavity Stamped Parts in batches. The integrated structure eliminated assembly gaps and stress deviation. After 3 years of market verification, chassis abnormal noise failure rate was reduced by 92%, improving suspension consistency and driving quietness.

Mountain Off-Road SUV Application

Off-road SUVs experience frequent impact loads and multi-directional vibration during mountain driving.

A professional off-road vehicle supplier replaced traditional split structural parts with XIAYI thick-plate multi-cavity formed components. After two years of full-load mountain road testing, no structural offset or damping attenuation failure occurred, reducing maintenance costs by 88%.

Coastal Engineering Machinery Application

Outdoor machinery operating in coastal areas faces high humidity and salt fog corrosion.

A coastal engineering machinery manufacturer adopted XIAYI integrated multi-cavity structural parts with heavy-duty anti-corrosion coating. Field application verified stable corrosion resistance with no rust failure or structural loosening.

Application Range

XIAYI Multi-Cavity Stamped Parts are suitable for integrated shock absorber structures, damping support systems and vibration control components used in passenger vehicles, new energy vehicles, SUVs, commercial vehicles and construction machinery.

XIAYI supports OEM and ODM customization, including cavity layout, wall thickness design and coating standards according to customer vehicle models, operating conditions and climate environments.
