Aging resist and no - sticky PTFE banded piston without steam treatment HRB60 used in car

PTFE piston bands is a new technology.It changes the traditional method,can band outside of sinter

piston.Main material is PTFE,can add different filler such as carbon fiber,glass fiber,graphite,bronze and

so on.Piston rings with different filler are used to different using area,they have different advantages.

Normally,PTFE+proportional graphite+proportional copper,this is a piston ring,used in shock absorbers.

Description:

Aging resistance and no-sticky powder metallurgy PTFE banding piston D32 auto Shock Absorber Piston

We mainly produces shock absorber pistons with many different dimensions.

We have a strong technical team to develop automatic skirting machines which can assure the

consistency of the pistons and also can improve the work efficiency. Compared with other suppliers, we

are sure we can offer you the more competitive price and quality.

Piston is based on powder metallurgy, filled modified PTFE material, using a special way to combine them

together, which has dual advantage of powder metallurgy and PTFE.

(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

Competitive Advantage:

We are professional company which produces different size and design for shock absorber pistons.

We have a complete set of testing equipment which can control the quality for the material.

Picture show:

Our company was set up in a beautiful city Ningbo, which is closed to Ningbo seaport and airport. Weiwo is a specialized company that is engaged in producing auto spare parts, designing and manufacturing electromechanical & machinery spare parts, hydraulic motor and hydraulic valves with different series, agricultural pruning shears and related agricultural products.

We have a strong R&D team with full of creative spirit and develop many new products every year and have obtained many invention and utility model patents.

The products include mechanical shaft and spares, diesel engine parts, sealing element, agricuture tools and equipment, hydraulic motors and valves, powder metallurgy parts, du bushing and bearing, shock absorber parts, stamping parts, plastic and rubber parts, in addition we design and manufacture automatic machine such as shock piston banding machine and groove cutting machine.

As a professional enterprise of manufacturing and trade, we insists on pursuing better quality on and on. We control the quality strictly from raw material to finished parts. We have carried out an integrated production system which is based on quality focus. We refer to the rigorous four aspects ( material importing control→ production line control→ QC department control→ logistic department control ) and quality control system to make sure all the products are intact and perfect before delivery.

As a seller, our products are exported to the whole world and sold nationally for many years. More than one half parts are exported to USA, Germany, France, Canada, Brazil, India, Malaysia etc., have set up good relationships with the customers from home and abroad. We have an intelligent marketing team who are exploring new markets, developing potential customers, solving problems and serving customers with orders well. We firmly believe that we are a competitive and friendly cooperator and our goal is for mutual benefit and long-term cooperation. All the staff in our company will always welcome customers from all over the world to visit and negotiate.
