Condensed mold liquid silicone is a commonly used material for mold making. Its main characteristics are good fluidity, high elasticity, high temperature resistance, wear resistance, and other excellent properties. It is suitable for complex shape and high-precision mold making. However, due to its long curing time, it can affect the production cycle, so how to shorten the curing time has become an important issue of concern for production personnel.

1. Increase the dosage of hardener
Hardening agent is one of the key factors in the curing of silicone gel. Increasing the amount of hardener can effectively shorten the curing time. However, excessive amount of hardener can affect the quality and performance of silicone gel. Therefore, when increasing the amount of hardener, it is necessary to make appropriate adjustments and controls to avoid affecting the quality of the product.

2. Increase the curing temperature
The curing temperature is also one of the important factors affecting the curing time of silicone gel. Raising the curing temperature within a certain range can accelerate the curing of silicone gel, but excessive curing temperature can cause defects such as bubbles and discoloration, thereby affecting the quality of the product.

3. Increase pressure
During the curing process of silicone, increasing appropriate pressure can accelerate the curing time. This is because pressure can promote cross-linking between silicone molecules, thereby accelerating the curing process. However, excessive pressure can cause defects such as indentation and deformation in the silicone gel, so it is necessary to make appropriate adjustments and controls.

4. Use accelerator
Accelerator is a special chemical substance that can accelerate the curing rate of silicone gel. There are various types of accelerators, and different types of accelerators are suitable for different silicone materials and curing conditions. Therefore, when selecting accelerators, it is necessary to choose and use them according to specific circumstances.

In summary, the reduction of liquid silicone curing time for condensation type molds requires comprehensive consideration of multiple factors. In actual production, it is necessary to choose appropriate methods for adjustment and control based on specific situations to ensure the quality and performance of the products.
