Why does the mold silica gel appear to dry on the surface and not dry on the inside?
Mold silica gel is a condensation type silica gel. It is cured by absorbing moisture in the air. In the process of making silica gel, the water is evaporated to dryness without adding proper amount of water. This phenomenon will occur. silicone molding manufacturer .Solution: This phenomenon is not a product quality problem, but because there is no water control, and the storage period of the silica gel is increased, and the shelf life is long, some phenomena will appear. As long as the silica gel is used, an appropriate amount of 0.05% water is added and mixed evenly. Some situations can be resolved.

Why does the mold silicone have poor tension?
In order to reduce the viscosity of the silicone and make the silicone easy to handle, the customer added a large amount of silicone oil to the silicone in the process of making the mold. This will make the silicone very soft, resulting in tensile strength and reduced tear strength. The phenomenon of deterioration of the tensile force, resulting in the mold is not durable, the service life is short, and the number of mold turning times is small.

Why does the mold appear to be oily?
The mold silicone itself does not emit oil. The oil emission occurs because of the addition of compound silicone oil (a compound of silicone oil and white mineral oil) during the operation, because white mineral oil is a petrochemical product, not a silicone oil.
