Low friction/ "ductile" material?

In summary, the speaker is developing a small product and needs a material, possibly plastic, for a metal part to slide through. The material should have a hole that is tight enough for the metal part to go through smoothly, but not too tight that it cannot fit during production. The speaker is looking for a material that can shrink to adapt when the metal part goes through. The material should also have good lubrication properties, such as PTFE or Teflon, if the metal part needs to be round or polished.

I'm developing a small product, And I need a material ( maybe a plastic ) for a metal part slide through. The material will have a hole and the metal part will go through but will have to be very tight hole and I'm afraid when making production obviously the measurements maybe be different and when assembling the parts the metal part will not be able to go through because it is too big gap or too tight so I need a material that when metal part goes through the material will shrink to adapt. And the metal will go through smoothly.


Is it possible to get a material like this.

Yes, but you must be more specific.

Can the metal part be round?
Can the metal part be polished?

Why must it be a tight fit? If for alignment then plastic will not be good. If for a gas or water seal, then use an O-ring seal.

There are plastics that have good lubrication properties. Consider PTFE = Teflon.
 

1. What is low friction material?

Low friction material refers to a material with a low coefficient of friction, which means it has a low resistance to sliding or moving against another surface. This property is desirable in applications where reduced friction and wear are important, such as in bearings, gears, and other mechanical components.

2. How is low friction material measured?

The coefficient of friction is measured by dividing the force required to move an object over a surface by the weight of the object. The lower the coefficient of friction, the less force is required to move the object, indicating a lower resistance to sliding.

3. What are some examples of low friction materials?

Some commonly used low friction materials include PTFE (Teflon), graphite, nylon, and certain types of plastics. These materials have a low coefficient of friction and are often used in applications where reduced friction is important.

4. What are the advantages of using low friction materials?

The main advantage of using low friction materials is the reduction of wear and tear on mechanical components, which can lead to longer lifespan and reduced maintenance costs. Low friction materials also help to improve efficiency and reduce energy consumption in moving parts.

5. What is a ductile material?

A ductile material is one that can be easily stretched or deformed without breaking. These materials have high tensile strength and can withstand large amounts of strain before rupturing. Examples of ductile materials include metals such as copper, aluminum, and steel.
