Lack of glue means that after the silicone product is formed, the product is incomplete or incomplete. In addition to the reasons for the mold, there are many reasons that will affect it. Hongtu Silicone summarizes the following points for you:

1. The weight of the silica gel raw material is not enough.

2. The unreasonable design of the size and specification of the raw material makes it difficult for the raw material to flow and fill the mold cavity when it flows under pressure, resulting in lack of glue. Usually, the cutting length of the raw material is too short, or the thickness is too thick.

3. The raw material discharge position is not accurate, and the rubber material cannot flow to the designated position.

4. The storage time of raw materials is too long, and the storage time of cut materials is too long, resulting in poor fluidity, and the cavity cannot be filled when it is under pressure.

5. The mold temperature is too high, and when the raw material flows under pressure, it has been vulcanized before it reaches the designated position.

6. The molding pressure is insufficient, and the rubber material cannot flow to the designated position.

7. Too much vulcanizing agent is added, and the raw material has been vulcanized before reaching the designated position.

8. Product structure or mold problem, the product structure is too complicated.

The above are some of the reasons for the lack of glue in the silicone products that Sitong has summarized for you. Which ones have you encountered?
