Deep Drawn Stamped Parts

XIAYI Deep Drawn Stamped Parts are integrated automotive structural components manufactured through advanced deep drawing forming technology. Designed for shock absorber housing assemblies, chassis support structures and damping isolation systems, these components provide high structural rigidity, stable dimensions and reliable corrosion resistance for long-term vehicle operation.

Unlike traditional multi-piece stamped and welded structures, XIAYI adopts one-piece deep drawing forming to eliminate welding seams and assembly gaps. Combined with high-ductility steel materials, stress relief treatment and protective coating technology, the products achieve excellent deformation resistance and stable performance under vibration, impact and different climate conditions.

One-Piece Deep Drawing Structure

The structural design of shock absorber components directly affects rigidity, alignment accuracy and service durability. XIAYI uses one-piece deep drawing technology to form complex cylindrical and housing structures without secondary welding.

This integrated forming method improves structural continuity, reduces weak points caused by welded joints and provides more stable performance during continuous vibration and impact conditions.

Seamless Forming Process

Traditional welded components may contain welding seams, residual stress and assembly deviations. XIAYI Deep Drawn Stamped Parts are produced through integral forming, creating a continuous metal structure with uniform stress distribution.

The seamless design reduces risks of weld cracking, local deformation and structural fatigue during long-term vehicle operation.

Controlled Wall Thickness

XIAYI applies multi-stage deep drawing processes to control material flow and reduce uneven thinning during forming.

The gradual forming process maintains wall thickness consistency within ±0.02mm, supporting accurate assembly and stable shock absorber performance.

Steel Material Selection

Different vehicle applications require different levels of strength, ductility and environmental resistance. XIAYI provides graded material solutions according to vehicle type and operating conditions.

ST14 High Ductility Steel

ST14 heavy-duty deep drawn steel with elongation ≥40% is suitable for SUVs, light trucks and harsh environments requiring higher deformation resistance.

The high ductility material reduces the risk of drawing cracks and improves structural reliability under heavy impact and vibration loads.

ST12 Cold Rolled Steel

ST12 light-duty cold rolled steel with elongation ≥35% is designed for urban passenger vehicles requiring stable performance and efficient cost control.

XIAYI matches suitable material grades according to customer application requirements, balancing manufacturing efficiency and product durability.

Stress Control After Forming

Deep drawing processes may generate internal stress that affects long-term dimensional stability. XIAYI applies low-temperature stress relief aging after forming to improve structural stability.

Residual Stress Reduction

All components undergo 4-hour constant-temperature aging treatment at 120℃ to release internal forming stress.

The process reduces springback effects and prevents delayed deformation during long-term vibration and temperature changes.

Dimensional Stability

After stress treatment, XIAYI performs secondary concentricity and roundness calibration.

This ensures stable piston rod alignment, consistent damping chamber positioning and reliable shock absorber operation throughout the service cycle.

Corrosion Protection Performance

Automotive suspension components are exposed to humidity, road salt, coastal salt fog and temperature variation. XIAYI provides different zinc coating solutions according to application environments.

Heavy-Duty Coating Protection

ST14 components adopt 12~14μm color zinc coating and pass 500-hour neutral salt spray testing without red rust pitting.

The protective coating improves resistance against salt corrosion and prevents rust particles from entering damping systems.

Light-Duty Surface Protection

ST12 components adopt 10μm zinc coating with 420-hour salt spray resistance for urban vehicle applications.

The coating structure provides reliable corrosion protection while maintaining production efficiency.

Manufacturing Process Control

Six-Step Deep Drawing Process

XIAYI applies a six-step closed-loop manufacturing process including coil leveling, progressive deep drawing, stress relief shaping, deburring, zinc passivation and dimensional inspection.

The controlled process improves production consistency and ensures every batch meets automotive quality requirements.

Intelligent Inspection System

XIAYI uses 3D optical scanning equipment for full dimensional inspection of finished components.

The quality system controls wall thickness, dimensional accuracy and surface defects, achieving batch stability CPK≥1.67 and factory defect rate below 0.1%.

Lightweight Structural Optimization

Modern vehicles, especially new energy vehicles, require structural components that combine strength and weight efficiency.

XIAYI optimizes deep drawing geometry and material utilization to reduce unnecessary weight while maintaining required rigidity and impact resistance.

Efficient Material Utilization

The deep drawing process forms complex structures from sheet materials with high utilization efficiency.

This helps customers achieve lightweight suspension solutions without compromising structural performance.

Application Cases

Coastal New Energy Vehicle Application

New energy vehicles operating in coastal areas face high salt fog corrosion and frequent vibration conditions.

A domestic coastal new energy vehicle OEM adopted XIAYI ST14 grade Deep Drawn Stamped Parts in batches. After 3 years of market operation, the components maintained structural stability with zero damping offset and chassis abnormal noise complaints. Shock absorber structural failure rate was reduced by 69%.

Mountain Road SUV Application

SUVs and light trucks operating on mountain roads experience repeated impact loads and lateral extrusion forces.

A professional off-road vehicle supplier replaced traditional welded components with XIAYI one-piece deep drawn components. After two years of full-load road testing, damping linearity remained stable and maintenance costs were reduced by 34%.

Northern Commercial Vehicle Application

Commercial vehicles in northern regions require resistance against low temperature and deicing salt corrosion.

A commercial vehicle manufacturer selected XIAYI graded deep drawn components. The products maintained structural toughness at -40℃ conditions with zero structural cracking and rust failure during field application.

Application Range

XIAYI Deep Drawn Stamped Parts are widely used in shock absorber housing assemblies, chassis support structures and damping isolation components for passenger vehicles, new energy vehicles, SUVs, commercial vehicles and construction machinery.

XIAYI supports OEM and ODM customization, including steel grade selection, wall thickness adjustment, structural design optimization and coating requirements according to customer applications.
