The Main Lubrication Problems of the Door Stopper:

    ※、Continuous noise reduction is poor, and noise occurs after the door limiter works for a period of time;

    ※、Strict long-life lubrication requirements, the grease of the door stopper volatilizes too quickly, and dries out after a period of time, and the lubrication is not enough, resulting in sticking, large resistance, and unclear gear position;

    ※、Incompatible with plastics, resulting in expansion and contraction of rubber blocks or plastics;

    ※、Strict environmental protection requirements, many greases have not passed relevant environmental protection certification;...

Solution:

    ※、For noise problems, you can choose a grease with a suitable consistency and a slightly larger viscosity, which can improve the noise reduction performance.

    ※、Since the lubricating grease will dry out after a period of time, it is necessary to choose a lubricating grease that is blended with high-grade precision base oil and sophisticated technology;

    ※、Use grease with good plastic compatibility;

    ※、In response to the requirements of the current market, all automotive products must meet environmental protection requirements. ...

Simulation bench experiment:

Basic introduction:

★The bench simulates the working state of the car door stopper, and can carry out durability tests on the slider type and ball type door stopper.

★The durability test can be carried out on the door stopper of the four doors at the same time, and the suitable grease can be found to prolong the life of the door stopper through the durability test.
