How to color silicone makeup bags during production?

The coloring process during the production of silicone makeup bags mainly includes several steps: selecting suitable silicone raw materials, color matching and mixing, mold selection and filling, vulcanization, and demolding.

1. Choose the appropriate color of silicone raw materials: When making silicone products, the appropriate color of silicone raw materials should be selected according to the design requirements. Most silicone raw materials are transparent and can be colored by adding a certain proportion of color paste.

2. Color matching and mixing: According to actual needs, different colored pastes are added to silicone raw materials in a certain proportion and thoroughly mixed to ensure uniform color distribution. When matching colors, attention should be paid to the combination of different colors and the amount of color paste used to avoid waste.

3. Mold selection and filling: Choosing the appropriate mold is crucial for coloring silicone products. The corresponding mold should be selected according to the shape and size of the product. Fill the prepared silicone raw material into the mold, ensuring that it is fully filled and free of bubbles.

4. Sulfurization and demolding: Place the filled mold into a vulcanizing machine for heating and vulcanization. Adjust the temperature and time according to actual needs. After the silicone product is fully vulcanized, remove it from the mold and complete the coloring of the silicone product.

This process not only involves the selection and blending of colors, but also the selection and use of molds, as well as fixing colors on silicone products through vulcanization. Through this method, silicone makeup bags of various colors and patterns can be made to meet different aesthetic and practical needs.
