Liquid silicone for mold making

Introduction to Mold Silicone:
Imitation jade table and chair molds generally use condensed mold silicone, while some customers prefer to use additive mold silicone, both of which are two component silicone and liquid silicone rubber; Component A is a flowable liquid silicone, while Component B is a curing agent (vulcanizing agent) that can be quickly formed by mixing the two. Among them, condensed silicone is non food grade, that is, industrial grade silicone, and added silicone is food grade silicone. The following recommended silicone for condensation type molds.

Mold silicone features:
1. Good liquidity;
2. Resistance to burning and high temperature;
3. No bulging or deformation;
4. Good tensile strength and strong tear resistance;
5. Multiple replicates;
6. Corrosion resistance and easy demolding;

Mold silicone application:
Mainly used in the production of imitation jade tables and chairs, imitation jade wash basins, imitation jade mirror frames, imitation jade furniture, imitation jade relief background walls, imitation jade handicrafts, imitation jade stairs, imitation jade Roman columns and other mold silicone.

Mold silicone operation method:
1. The mold opening methods for silicone molds are divided into injection mold (wrapping mold), brush mold, and reverse mold.
2. Taking injection molding as an example, the operation method is as follows:
Prepare the mold type → Make the mold frame → Fix the mold type → Weigh the silicone → Stir and vacuum the silicone → Pour the silicone → Cure the mold → Open the mold → Complete

Precautions for using mold silicone:
1. During the production process of silicone molds, incomplete solidification of the mold often occurs, mainly due to incorrect silicone ratio and differences in the curing and insulation time after casting. Of course, it can also be affected by the environment, such as smoking, which can also affect the inability of silicone to solidify.
In order to achieve the best usage effect of the silicone mold, please store the mold for at least 24 hours before use.
3. Ensure the cleanliness of the silicone production container, and do not mix the added silicone with the condensed silicone operating container.
4. Water, impurities, organic tin catalysts, acids, bases, and other organic compounds containing sulfur, phosphorus, and nitrogen can also affect the solidification of silicone. These substances should not be mixed or come into contact during operation.
