Carbon Fiber As Filler Ptfe Banded Piston With Density 2.18 , Car Shock Absorber Parts
Our company has both automatic and manual machine.
For mass production order, we will choose automatic machine, can reach about 4000 ~ 5000 pcs per shift
per one machine.
For samples and orders with small quantity, we will still use manual machine because we need to change
the toolings very often and will waste time.
But banded pistons from both automatic and manual machine, all have good appearance, consistent size
and properties.
Specifications:
| Physical performance for shock piston | tensile strength | More than 15MPa |
| elongation @ break | More than 200% | |
| shore hardness | 57 - 61 | |
| density | 2.06 – 2.19 g/cm3 | |
| wear | Less than 50mg | |
| friction coefficient | Less than 0.3 | |
| highest working temperature | 260℃ |
Description:
We produce different size of shock absorber pistons. These pistons can be used in different car or
motorcycle shock absorbers.
Sinter pistons based, band PTFE rings on outside, can assure the good seal and wear resistance.
Processing for sinter pistons
Mixing powder——Forming——Sintering——Sizing——After treatment——Steam treatment——Oil
impregnant——Packing——Shipping
There are plenty of testing machines in our company.
Tensile testing machine which can test tensile strength & elongation @ break according to GB/T
1040.2/1B-2012
abrasion testing machine which can test friction coefficient & abrasion loss according to GB/T3960-
1983(1989)
Density balance can test material density to assure the material quality and homogeneous distribution
Shore Hardness (D) tester
Rockwell hardness tester
Projecting machine
We also develop the testing machines by our team workers. For example: blow-off testing machine,
fatigue testing machine and friction testing machine.
Size: 30# PISTON
PTFE piston ring banded on sinter piston
PTFE coated bushing reduces wear
Four round holes & six square holes design
Shock Absorber Type: Hydraulic
Wear resistant piston ring reduces friction and possibility of leakage
Certification: ISO/TS16949
Applications:
Used in car or motorbike shock absorbers
Competitive Advantage:
We can produce bands rings by itself to low down the cost and control the quality at home, at the same
time we can design and produce automatic banding machine and non-standard testing machine, can
test drawing force testing and oil immersion testing.
