Silicone Compression Mould Gasket Medical

Product Details

The choice of mold making form and the selection of mold line are very important. First, it is convenient for mold taking. Second, the part line should be selected without affecting the overall effect of the product. Third, it does not affect the product quality. For example, the part line position of the water series product is too high, when the part line is required, there are many materials, and the product cracking is easy to occur; the fourth is to reduce the process operation steps, such as opening half of the mold.

In order to prevent the flow of the silica gel, the mold is fixed in a regular range by wood.When the mold is opened, the first part of the mold is separated by the wood and the sludge, and there is no gap between the sludge and the mold, and the surface of the sludge is smooth and flat. After the above work is completed, the plaster or mold is coated with Vaseline or sprayed with a release agent. The smooth product is coated with a clean cotton cloth and coated with Vaseline evenly on the mold for 30 minutes. The species is fully absorbed with Vaseline, and the surface of the mold is wiped clean with a clean cotton cloth, and the surface is required to be bright; while the product with texture is uniformly coated with Vaseline, the silica gel can be adjusted according to the formula. When the silica gel is formulated, it should be stirred in an irregular direction, so that the curing agent and the silica gel are thoroughly mixed to minimize the mixing of air into the rubber. The smooth product is preferably vacuumed when the first layer of glue is applied, and the vacuum degree is required to be maintained at -0.1 Mpa. 7-8 seconds.
