Product Description
Multi Groove Powder Metallurgy PTFE Banded Piston with Stable Oil Flow Control
Product Overview

A Banded Piston is a critical internal component used in automotive hydraulic shock absorbers. It consists of:

  • Precision powder metallurgy piston body
  • Low-friction piston band
  • Hydraulic flow control structure

Unlike conventional metal-to-cylinder contact designs, the piston band provides a controlled sliding interface between the piston and cylinder wall.

Main Functions
  • Maintaining piston alignment
  • Reducing friction
  • Preventing cylinder wear
  • Improving hydraulic sealing stability
  • Supporting consistent damping performance
XIAYI Manufacturing Advantage

XIAYI specializes in automotive suspension precision components, especially powder metallurgy and hydraulic damper internal parts. Our banded piston solutions focus on secure piston band retention through optimized design and manufacturing processes.

Secure Retention Features
  • Precision groove design
  • Controlled assembly process
  • Strict dimensional inspection
  • Pull-out force verification
Risk Reduction Benefits
  • Piston band separation prevention
  • Abnormal cylinder wear reduction
  • Suspension noise elimination
  • Damping performance stability
Material Technology
Powder Metallurgy Piston Body

Manufactured using high-performance iron-based powder metallurgy materials with excellent dimensional stability and mechanical strength.

Material Characteristic Performance Benefit
High density Improved impact resistance
Stable metallurgical structure Better fatigue durability
Controlled composition Consistent mechanical properties
Excellent formability Complex design capability
Piston Band Material

Produced using advanced low-friction materials including modified PTFE compounds, engineering polymers, and wear-resistant composite materials.

  • Low friction coefficient
  • Excellent wear resistance
  • Hydraulic oil compatibility
  • Temperature resistance
  • Long-term dimensional stability
Performance Advantages
Reduced Metal-to-Metal Contact

The piston band creates a protective sliding layer that reduces direct metal contact, surface damage, friction heat, and operating noise.

Benefits for vehicle manufacturers:

  • Improved suspension refinement
  • Reduced warranty risk
  • Longer damper service life
Stable Damping Performance

Maintains proper piston alignment to prevent uneven clearance, tilting movement, and abnormal wear.

Ensures consistent performance:

  • Stable hydraulic response
  • Consistent damping output
  • Smooth suspension operation
Long-Term Durability

Designed to withstand millions of movement cycles, continuous hydraulic pressure changes, temperature variation, and road vibration impact.

  • Strong band retention
  • Wear resistance
  • Long operating life
  • Stable performance throughout vehicle usage
Band Groove Precision Control

Piston band retention depends heavily on groove accuracy. Critical control parameters include:

Control Item Purpose
Groove width Ensures proper band positioning
Groove depth Controls retention strength
Groove profile Prevents band movement
Surface quality Improves assembly reliability

Poor groove control may lead to loose piston bands, reduced retention force, and premature failure.
