2.Product Parameter

Product Name Aluminum Alloy Rail Transit Shock Absorber Components

Product Material 6061, 6063, etc.

Product Specifications Support non-standard customization

Product Processing Method CNC Processing

Surface Treatment Anodizing, sandblasting, powder coating, etc.

3.Product Feature And Application

1. High-strength and lightweight design

Adopting high-strength aluminum alloys such as 6061-T6 and 7075-T651, the weight is reduced by 40%-50% compared with traditional steel components, while maintaining excellent fatigue resistance and impact resistance. Applicable to weight-sensitive parts such as high-speed trains and subway bogies, reducing energy consumption and improving operating efficiency.

2. Precision CNC processing to ensure high precision

Four-axis and five-axis CNC processing accuracy ±0.01mm, which can meet the needs of complex curved surfaces, special-shaped structures and high-precision assembly. Applicable to key components such as shock-absorbing bearings, suspension systems, connectors, etc., to ensure long-term stable operation.

3. Corrosion-resistant anodizing treatment

Hard anodizing (HV≥400), film thickness 15-25μm, salt spray resistance test ≥1000 hours, adaptable to harsh environments such as humidity, acid and alkali. Optional special treatments such as conductive oxidation and black oxidation can meet the needs of different working conditions.

4. Excellent shock absorption performance Combined with elastic structure design (such as honeycomb structure, hollow weight reduction), it effectively absorbs vibration, reduces noise, and improves passenger comfort. Ensure long-term use without deformation and breakage.

4. Application scenarios of aluminum alloy rail transit shock absorber components

1. High-speed rail & EMU

Bogie shock absorber components: reduce vibration during high-speed operation and improve riding comfort.

Car body connectors: lightweight design, reduce energy consumption, and extend service life.

2. Subway & light rail

Suspension system components: adapt to frequent starts and stops, reduce track wear.

Track fixtures: corrosion resistance, fatigue resistance, and reduce maintenance costs.

3. Tram & Maglev Train

Shock absorber bearings: adapt to complex urban road conditions and reduce noise pollution.

Car body structural parts: high-strength aluminum alloy to ensure safety and lightweight.

4. Railway infrastructure

Bridge shock absorber pads: buffer the impact force when the train passes and extend the life of the bridge.

Platform anti-vibration components: improve the stability of platform equipment and reduce the impact of vibration.

8.FAQ

Q1: Does it support small batch customization?

A: Yes! The minimum order quantity is 50 pieces, and samples are delivered in 7-15 days, which is suitable for R&D trial production and short-term project needs.

Q2: Will surface treatment affect shock absorption performance?

A: No! Anodizing only increases the film thickness at the micron level, does not affect the structural strength, but improves wear resistance and corrosion resistance.

Q3: Does it support non-standard size customization?

A: Yes!
