Latest company case about Shenzhen Hanast New Material co.,LTD Certifications

Mold silicone includes condensation-type silicone (100:2) and addition-type silicone (1:1). It is widely used in mold making for cement products, plaster products, resin products, Chinese/European style building materials, decorative materials, carbon fiber products, automotive parts, plastic parts, candles, handmade soaps, and more. It features simple operation and high-quality mold reproduction.

Shenzhen Hongtu Silicone has recently received many inquiries from new customers about why mold silicone has a low number of mold-making cycles. What are the reasons? Here is an analysis of the reasons; (for details, please contact a Hongtu Silicone specialist directly)

1. Silicone material selection; Due to the large market coverage of silicone materials, some vendors inevitably add fillers to the materials to gain a price advantage, but this often results in a poor user experience. For example, mold silicone mixed with powder may only be used 8-100 times to mold cement products before the silicone mold cracks or becomes brittle due to aging. Hongtu Silicone focuses on meeting the needs of its users, improving material performance and lifespan. Cement products can typically be molded 300-500 times or more, while plaster products can reach 1000 times – this is the difference.

2. After choosing the right material, the mold-making method is also crucial. For example, when making brush molds, it is recommended to apply at least four layers of silicone. Applying too thin a layer will affect the wear and tear of the silicone mold. Whether making casting molds or brush molds, the surface of the master mold must be treated with a release agent. This will result in a more refined and beautiful silicone mold surface, which is beneficial for subsequent mold-making production.

3. Pay attention to the amount of curing agent and ensure thorough mixing. Avoid forceful demolding during the molding process, as this can easily damage the product and the mold, increasing unnecessary costs for the company.

4. Used silicone molds should be stored properly, avoiding exposure to wind and sun. Less frequently used silicone molds can be washed with soapy water and stored in a dry, cool place.

The above are some reasons summarized by HANAST for the low number of times silicone molds can be made. We hope this information is helpful. Other reasons may exist, requiring specific analysis of each case. For more details, please follow HANAST Silicone.
