Product Description

 

Black Shock Absorber PTFE Piston Rings Seal For Cars , Trucks

 

 

Description

 

ERM offer a new type of PTFE bonded piston .

ERM offer this new design shock absorber piston which bonded filled teflon , improve the Piston using life , and improve shock absorber quality .

So PTFE material and bonded Process is very important .

ERM ptfe bonded have a special producing process

PTFE material “

PTFE +15% Graphite

PTFE+Graphite + Glass fibre

PTFE+MOS2 + Glass Fibre

PTFE+ 15% Carbon Fibre

PTFE + 30% COPPER

 

 

Competitive Advantage:

 

This is a new design PTFE coated Piston .this is PTFE lip is used like a oil seal to protect the piston and cylinder suface .

  1. Oil seal is designed with PU oil seal usage in mind. Padding is inserted with cold pressure which creates PTFE that act as oil seal This effectively reduces grinding, leaking, groove roughness, heat exhaustion, noise, and other oil seal related issue due to high pressure  It also increase shock absorber’s life span
  2. PTEF packing for car modification is slow to produce and has limited production quota per year. However, it is very resistance to grinding and hard to break down We do not recommend factory that provides piston repair service to use this because if they install this they will have nothing to repair later on
  3. Due to difference in usage environment and design concept. We can adapt to any PTFE packing material and any piston shape We can create diameter range from 25 mm to 152 mm

Shock Absorber PistonThe Latest cladded machine

Piston Body:

Piston Body is made with international standard, and strengthened using precision machine pressurization. It did not rely on heat treatment and secondary processing to improve surface hardness.

Implantable port:

1.5mm Width and 1mm Depth in spec.In addition, to prevent the “hitting the pole wall” under pressure when installing shock absorber diagonally,implantable port can come with 1mm width specification

Groove Depth:

Groove has a 0.65mm depth. When inserting PTFE into groove vertically, it strengthens piston ring so it does not cause rotation and shedding under 60

Piston Groove:

Groove has a 0.5mm width design to reduce metal contact surface area his helps reduce friction coefficient, edge hardening due to long use, and cladding PTFE packing loosening due to rotation.

Piston Face:

Original 0.2mm piston surface will tear, break, or brittle after long use The newest generation cladding machine forming process with specially made 1mm PTFE packing ensures PTFE to gain chaining hardness and elasticity on 0.4mm piston surface

Groove Width:

The Groove has 1.0mm width and 0.65mm height in design Our design enable special PTFE packing to create super tie elastic bond when inserted into the metal wall. This prevents PTFE packing grinding problem.

PTFE Packing:

  1. A better pipe production method is double sided pressurized forming instead of plate punching The raw materials are repeatedly heated and cool down for five days before any processing..
  2. he worst processing method for the PTFE of Piston is the lather process because its’ PTFE surface will break under 500-1000 spin speed Because of this, a good shock absorber grinding ring will form oil dirt deposit and makes the absorber harden over time.
  3. Factory form PTFE packing is made with high temperature cl
