Main lubrication problems of door stopper:

※, continuous noise reduction is poor, the door stopper makes noise after working for a period of time;

※, strict long-life lubrication requirements, the grease of the door stopper evaporates too quickly, becomes dry after a period of time, and the lubrication is insufficient, causing jamming, large resistance, and unclear gears;

※, incompatible with plastics, resulting in rubber blocks or plastic expansion and contraction;

※, strict environmental protection requirements, many greases have not passed the relevant environmental certification;

Solution:

※, noise problem, you can choose a grease with appropriate consistency and slightly higher viscosity to improve the noise reduction performance;

※, for the lubricating grease that will dry after a period of time, you need to choose a lubricating grease made of advanced precision base oil and precise process;

※, 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 test:

Basic introduction:

★The bench simulates the working state of the car door limiter, and can perform durability tests on the slider and ball-type door limiters.

★The durability test can be performed on the door limiters of four doors at the same time, and the suitable grease can be found through the durability test to extend the life of the door limiter.
