Water and Moisture Absorption Water absorption and moisture absorption is a very common and common property in plastics, the natural environment is full of water vapor, after the plastic absorbs its moisture, it will cause many property changes, the most obvious of which is the increase in weight and size, this characteristic is called Water […]

Thermal Expansion and Shrinkage of the Bushing Basic introduction When a material is heated, its molecular motion intensifies, causing the material to expand; As the material cools, the molecular motion weakens and the material shrinks. This size variation can affect the accuracy and functionality of the product. The thermal expansion and contraction of plastic is […]

What is the expansion coefficient? Most objects and materials have a characteristic, the temperature rises, the size increases; The temperature drops, the size becomes smaller, the so-called thermal expansion and contraction, the object expands and contracts when it is heated, and contracts when it is cold. A few materials are non-thermal expansion and contraction, as […]

What is bushing Bushing, Bushes The shaft is one of the core parts of a machine and has the function of transmitting force by rotation. The meaning of matching is to use an object between the hole and the shaft to act as a buffer and reduce friction and wear. To sum up, the shaft […]

What Is Pull-off Force Noun Explanation Pull, refers to the force of pulling out and extracting from bottom to top. To loosen, withdraw, or remove two objects that have been combined. All of the above will be interference fit (tight fit), because if there is no interference, there will be no Pull-off Force, and they […]
