When it comes to selecting a manufacturer - the more processes the better ! And you will find plenty of rubber manufacturing processes to choose from at Kennwu.
There is a large selection of common elastomers as well as custom formulations available at Kennwu. Note the processes and materials listed here are just a sampling of our offerings. Contact us for a more comprehensive list of materials, custom compounds, and processes to meet your specifications.
The material selection process involves asking the right questions concerning
the application and environment the part will be exposed to. Rubber compounds are all unique in
their own way,
and asking the right questions during the selection process enables us to match the right compound
to the part.
By understanding some of these considerations, you are better able to control the cost
of your product while achieving the proper performance levels.
Some common questions we might ask are:
What is the application or function of the part?
Knowing how a material will be used in its end-use application is imperative during the material selection process.
Will the part:
Is there a cost target for a material that we should consider?
Will the part be located inside or outside?
What, if any, are the temperature requirements?
Is there exposure to specific chemicals?
Will the part be exposed to an abrasive environment?
Are there any physical property requirements?
Does the part need to absorb vibration?
Is the part being used as a sound dampener or deadener?
Does the part need to meet any regulatory requirements?
Not all of the properties requirements above may apply to your products applications. By engaging us in the proper dialogue, and based upon the answers to the above questions, we can recommend a material to suit the application and environment of the part.
Elastomer Hardness Selection
Rubber materials are available in durometers ranging from 20 Shore A to 90 Shore A, Commonly, materials hardness range in most general applications from 50 Shore A to 80 Shore A, with the majority of sealing products being made from materials with 70 Shore A hardness. Depending on your specific application, Kennwu will be able to recommend a proper hardness for your rubber material.
In dealing with very hard or very soft materials, some manufacturing limitations will apply. Parts that have a complex geometrical design or deep undercuts are more difficult to manufacture from very soft (less than 30 Shore A) or very hard (greater than 80 Shore A) materials.
Extruded rubber products differ from molded rubber products based on how they’re made.
Extruded parts are forced through a die of the required cross section under pressure of an extruder.
These parts are often made with soft, unvulcanized rubber compounds that are fed into the extruder.
The resulting extrusion leaves the rubber in a soft, pliable state.
In this case, the finished extruded products will typically need to be vulcanized, or hardened,
before they are rendered usable.
We provides rubber driven by innovation.
