Stopper Bolts - Shock Absorption Type, Hex Socket Head
Frequently asked questions about this product (FAQ)
Did it fall off without a few collisions? Is it a quality issue?
The stopper is sintered on the bolt and can absorb the impact force from the front, but when the force point is too inclined towards the side, it is relatively easier to fall off.
Will there be any small burrs on the surface after arrival that will affect the use?
It does not affect use. This product is formed by one-time injection molding, and there may be small burrs after molding, but it does not affect use. If there are special requirements for appearance, you can request special production from Mismi customer service.
What is the service life of polyurethane gaskets compared to rubber materials?
Generally speaking, polyurethane is more excellent in terms of wear resistance and mechanical strength, with a longer service life. However, polyurethane is more sensitive to changes in the usage environment, especially its hydrolysis characteristics, which can shorten its service life.
How can polyurethane and resin heads be used differently? What is low rebound polyurethane?
Polyurethane belongs to the category of elastomers and has better cushioning performance than resin. The material of resin is hard and has much higher mechanical strength compared to polyurethane, which can withstand greater impact forces.
The material of low rebound rubber is very special, which can reduce the thermal energy generated by the workpiece after impact
Can polyurethane be wiped with alcohol?
Yes, only a small amount of alcohol can be applied for wiping. Polyurethane is a material that is not resistant to chemical agents and is prone to corrosion. However, after applying a small amount of alcohol, it is possible to dry it as soon as possible or naturally. Other highly corrosive chemicals, even in small amounts, cannot be applied.
Polyurethane has a wide range of hardness choices. Are there any tolerances for various types of hardness, and if so, what are the tolerance values?
All types of hardness have tolerances, generally around Shore ± 5 °, which is the normal value.
