Silicone replica molds can usually be used about 15-25 times.
Silicone replica molding is a commonly used prototype model making process. It makes a prototype (such as CNC processing, SLA laser rapid prototyping or 3D printing) and then uses this prototype to make a silicone mold. After the silicone mold is made, the prototype model can be copied through vacuum infusion. This replica molding technology is suitable for small batch copy production in the fields of automobiles, consumer electronics, medical and other fields. The specific process is as follows:
Prototyping: First you need to make a prototype, which can be done through 3D printing, CNC machining, etc.
Silicone replica mold
Silicone mold making: After the prototype is ready, use liquid silicone material to cover the prototype to create a silicone mold. Silicone molds take a certain amount of time to cure, usually about 8 hours.
Injection copying: After the silicone mold is cured, the liquid resin material is injected into the mold. After the curing process, the copied product can be obtained.
It should be noted that the life of the silicone mold will be affected by many factors, including the quality of the silicone, the standardization of operations during the production process, the use and maintenance of the mold, etc. Therefore, actual service life may vary. In addition, in actual operations, in order to ensure the quality of replica mold products, the mold is usually inspected and maintained after each use to extend its service life.
