Good Wear Resistance Shock Absorber Piston With Flared Design For Automobiles

XIAYI produces and supplies shock absorber components of any complexity, which are used in trucks, cars, motorcycles and quadbikes.

Over the years we have proven ourselves as a reliable supplier operating on markets of many different countries.

The technical capabilities of our company allow us to produce shock absorber parts in exact accordance with client’s requirements.

We are currently producing the following shock absorber parts:

various kinds of sinter parts such as rod guide, base valve, piston...
valve shims with different function such as rebuilt valve, leaf spring, throttle plate...
oil seals with different designs;
piston rods with solid or hollow design;
stamping parts such as spring seat, bracket...
bushing with long and short design;
PTFE bands and other PTFE products;

We also design and manufacture automatic banding machine which can produce shock absorber banded pistons. It is the best choice for powder metallurgy factory and shock absorber factory.

The Piston Process
Step 1: 100% automatic inspection of the OD ensures the correct amount of material is applied, thus yielding the finished dimension desired.

Step 2: Computer-controlled application of the permanently banding material.

Step 3: 100% automatic inspection of the OD ensures the desired finished dimension is obtained after process banding material.

Step 4: Apply Permanently banding 100% pass-thru gauging of each finished piston to assure the piston meets functional requirements prior to packaging.

Step 5: Product ready for assembly.

Description:

High quality shock absorber piston, used in various cars and trucks

Properties of banding ring can be tested in our company, we have the following test equipment:

Tensile strength testing machine, friction & abrasion testing machine, density balance, coefficient of linear

expansion testing machine and so on.

We also design and manufacture non-standard testing machine which can do blow-off test after banding.

Adhesion test: ring must be tested in shock absorber according to characteristics below:

Piston must have a minimum diameter of groove.

---pressure tube must have maximum internal diameter

---traction force from 4700 to 5390 N and speed=1.5m/s according to condition below

---course =50mm

---frequency =574RPM

---moment must be applied at the end of piston rod = 3Nm

---temperature = 130/160℃

Ring withstand 10min without deformation on adhesion test.

Properties of the banding ring:

Density = 2.03-2.110g/cm3

Hardness = 57-61 shore “D”

Tensile strength = 16Mpa minimum

Elongation = 300% minimum

(1)Advantage of powder metallurgy:

Unique chemical composition and mechanical physical properties

(2)Advantage of PTFE:

Chemical and aging resistance, temperature endurance and no-sticky performance

(3)Advantage of piston:

High carrying capacity, good wear resistance, low friction coefficient, good seal and so on

To date, XIAYI's facilities allow to producing up to 1.5 million additional shock absorber parts per month; and if necessary, this number can be increased by acquiring new equipment. One of our advantages as a manufacturer of shock absorber components is price/quality ratio – we offer competitive prices and provide high quality in full accordance with customer’s drawings.

The quality of products supplied by XIAYI is ensured at every stage of production – from planning to packaging and delivery. Control is carried out at three levels: at factory in accordance with internal standards; by head office expert; by independent expert organizations, such as SGS, with appropriate certificate, by prior arrangement with client. This ensures stable product quality and customer’s confidence while cooperation with us.
