Possible causes due to seals:

1. The physical properties of the sealing ring compression permanent deformation are too poor.

2. The initial compression of the sealing ring is too small.

3. The dimensional tolerance of the sealing ring is too large, so that the designed compression cannot be achieved.

Possible causes due to seals:

1. After the sealing ring is squeezed, oil will leak out and pollute the lens.

2. After the sealing ring is steamed at high temperature, the volatile molecules will pollute the lens.

3. Failure of the sealing ring leads to failure of the seal.

Possible causes due to seals:

1. The hardness of the sealing ring is too soft, which leads to agglomeration in the vibrating plate and cannot run smoothly.

2. The surface of the product is too bright, causing the sealing rings to stick to each other.

3. The surface treatment of the vibration plate is not conducive to the running of the sealing ring.

Possible causes due to seals:

1. The material has poor physical properties such as tear resistance

2. The self-lubricating effect of the material is poor

3. There are dark wounds when the seal is stripped

Possible causes due to seals:

1. The material has poor high temperature resistance and cannot withstand 1008 hours of aging at 125 degrees Celsius or higher, as shown in:

       1) After high temperature aging, the pressure change performance becomes poor, resulting in permanent deformation

       2) After high temperature aging, the hardness changes too much, and the rebound becomes poor

2. The interference design of the seal is unreasonable

3. The dimensional accuracy of the seal is not enough

Possible causes due to seals:

1. The pressure change performance of the material is poor in high and low temperature resistance.

2. The physical properties of the material are not stable enough under the conditions of cold and heat shock and different humidity

3. The dimensional accuracy of the seal is not enough, and the interference design is unreasonable

Possible causes due to seals:

1. Suppliers lack professional support in material selection, and generally can only be judged through routine performance testing, relying more on customer test results.

2. The supplier lacks professional technical support on the design side.
