In the production of silicone products mold, the first problem to be considered is the choice of mold materials. According to the quality, quantity, structure and so on to determine the selection of silicone mold.
The preparation also need to take into account the room temperature, the mold strength and hardness, the specific method is to determine the total amount of silicone mold volume, then the A and B components according to the proportion of accurate weighing, placed in containers and evenly stirred. Silicone molding is one of the most simple method of rapid mold, good elasticity and replication performance, with silicone rubber products will not affect the dimensional accuracy of the replication model, the segmentation of good, not on the mode, can be directly used for casting. It is possible to cut out the master mold along a predetermined parting line.
We live in a lot of plastic, rubber products, products can be poured into the mold with silicone. Various types of silicone rubber mold production methods will be different, how to make silicone mold, then in the production of silicone mold preparation work,
What should be noticed in the mold?
According to the production of silicone rubber mold the different mode of operation, there are three kinds of mold: mold, mold package brush (sheet die, die, die, three-dimensional plane) perfusion model.
Silica gel mold: the deployment of good materials, into the imitation of the clean material can be. In order to save materials, make molds thinner, can also be divided to increase the tension of the mold coating; can paste gauze like, in the conditions of 20 degrees at room temperature for 2 hours can be made into elastic body, you can use a day later.
If the customer needs to do large products, such as piece mold, will use liquid silicone mold with high hardness to die; instead, a complex pattern of mold and tiny, such as packet mode, must use soft liquid silicone mold to mold.
