What's the Rubber anti vibration mounts?

 

AV Products cylindrical mounts are made with the finest quality rubber and metal to meet the most demanding requirements for effective vibration isolation and noise damping over a wide range of frequencies while managing motion. Cylindrical mounts, also called cylindrical bobbins or bobbin mounts are commonly used for both active and passive vibration suppression as well as shock and structure-borne noise control. Cylindrical vibration isolators can be installed in both compression and shear designs.

Each cylindrical mount is available with natural rubber as well as specialized compounds as seen below.

Additional compounds available: Chloroprene (Baypren, Neoprene), Ethylene Propylene Terpolymer, Ntrile Butadine (Perbunan), Styrene Butadiene, Butyl, Polyurethane, Silicone Rubber and Fluorocarbon (Viton). Stainless steel threads are available for substantial volume orders.

Why Choose us

Our Advantage

The reasons that we could cooperate with our customers in a long term: suitable material, innovation strength, strictly quality management and more experience. We have more 20000 molds and large raw material recipe database, could solving each sealing problems.

My company and the customers a solid partnership depends on the achievement of the following aspects: the basic experience material applicability, innovation strength, strict quality management and function integration. Our company has more than 20000 sets of molds with huge database of raw material, processing the sealing problem of seals in various media and various conditions with enough experience.

The procurement division, according to the importance and function of sealing parts, sometimes referred to as C class supplies purchase, in fact the sealing member should belong to a class material. Hydraulic and pneumatic valve seal is the core component technology.

Material Advantage

Cooperation with Dupont, JSR, Dow corning and large raw material recipe database, make our material properties are relatively stable, ensure quality. Rubber formula design ability which make us  meet customers demand better.

Product Inspection&Quality Control

Material Inspection:
 Take testing for all storage material, and issue the corresponding raw material property report, meanwhile compare with raw material own property report, two reports property value is consistent, then put into storage.

Mold Inspection:
Die Mold development finished or after cleaning, we will check the full size of the mold, ensure quality for each cavity's product.

Product Inspection:
 During production, inspectors will check semi-finished products, ensure product process and make the defective rate control in a reasonable range

Quality Control:
 Quality Department will check product appearance for each batch.

Quality Department will check product appearance for each batch:
 Optional Sorting Machine ensure products appearance, 100% qualified.


Failure forms and Solutions
★Extrusion
Description
Sealing parts with rough edge is usually in the low pressure side.
Reason
Clearance/pressure is too large; hardness/elasticity is too low; groove gap is too small; irregular clearance size; improper size of sealing parts.
Solutions
Reducing clearance size, choosing higher hardness or better elasticity material, reasonable groove design.
★Twist
Description
Sealing parts become twisting.
Reason
Improper installation, movement speed is too low, material too hard or elasticity too small, improper groove size, rough groove surface.
Solutions
Correct installation, choosing high elasticity material, suitabel groove designation and surface finish, trying to use support ring.
★Permanent Compression Deformation
Description
Contacting surface of Sealing parts display permanent deformation.
Reason
Pressure is too large, higher temperature; un-finished sulfuration treatment; material is overexpansion in the chemical medium.
Solutions
Choosing material which is low deformation rate; suitable groove design;confirming materials and medium are compatibility.
★Installation Damages
Description
The whole or part of sealing parts appear wound.
Reason
The edge of groove is sharp, size is not suitable. Hardness or elasticity is lower; Surface is dirty.
Solutions
Clear sharp edge; design more reasonable groove designation; choose suitable size; choose more elasticity and higher hardness sealing parts.
★Excessive Compression
Description
Sealing parts contacting surface is plane deformation, maybe have crack.
Reason
Unreasonable designation; material deformation, which is caused by heat and chemical medium; or lager pressure
Solutions
Groove designation shoule consider material deformation, which is caused by heat and chemical medium; or lager pressure.
★Heat Corrosion
Description
High temperature contacting surface shown radial crack; maybe material change softer, or material become shiny due to high temperature .
Reason
Material could not bear high temperature, or temperature beyond estimated , or temperature change frequently.
Solutions
Choose high temperature resistance material, if possible, try to reduce temperature of sealing surface.
★Electro-corrosion
Description
Seal fade also have powder residue on the surface.
Reason
Chemical reactions bring electrolysis, unreasonable groove designation, material and medium is incompatible
Solutions
Choos suitable material with medium, checking groove designation.
★Wear
Description
The whole or parts of is wear, material wear particle could be found.
Reason
Surface cleaness is worse, more higher temperature, seal surface treatment is notThorough.
Solutions
Using groove cleaness which is suggested, clean wear pats.
★Pressure Blasting
Description
The seal surface appear bubbles, pits, scars; pressure material absorption gas in medium, when the pressure is suddenly reduced, the gas absorbed by the material fast escape. Cause sealing epidermal blasting.
Reason
Pressure changed frequently, hardness and elasticity of material too low.
Solutions
Choose higher hardness and elasticity material, reduce decompression speed.
★Chemical Corrosion
Description
Chemical corrosion could cause each kinds defects, such as crack, small hole or color fading, sometimes, chemical corrosion could be tested by instruments.
Reason
Materials and medium does not match, or higher temperature.
Solutions
Choose more chemical resistant material.
★Gas evolution
Description
It is difficult to test this flaw, normal form--section size become smaller.
Reason
Improper sulfidizing, hardness too low, or used plasticizer material.
Solutions
Avoid using plasticizer material, assure the sealing parts through correct fluidization process, in order to reduce leakage.
★Pollution
Description
Section of sealing parts have dirty matters.
Reason
The producing environment is damaged, material is corrosion, material is non semiconductor industry grade material.
Solutions
Pay attention to cleaness when producing and packing, controlling environment of deliverying and application.
