what problems often occur when prototype model silica gel is used?

Shenzhen prototype factory has been engaged in prototype model production for more than 11 years, especially when using prototype model silica gel to make product models, many problems are often encountered, the following is a summary of the problems of the common prototype model silica gel in Shenzhen:

1. What about silicone adhesive mold?

Shenzhen prototype factory believes that there are two reasons for this situation:

one is because of the previous model (Product model) There is no reasonable treatment, so the mold should be treated before the mold is opened. For example, the surface of the mold is thick and dry or the mold is very complicated. It must be carefully polished and cleaned. Then brush the mold release agent evenly. Common mold release agents include Vaseline, detergent, liquid paraffin, etc. In actual operation, different mold release agents can be painted according to the material of the mold.

The second is to pour the curing agent into the mold if it is not evenly stirred. When it is removed, it is dry and dry.

2. Silicone Mold after curing uneven curing?

Shenzhen prototype factory believes that this phenomenon is caused by:

1. The ratio of silica gel to curing agent is inaccurate and is not weighed as required;

2. After mixing the silicone with the curing agent, it is not carefully stirred evenly. This situation will cause the die to be scrapped and should be avoided as much as possible.
