Among the many ways to make prototype models, one method is vacuum compounding, which is a method of batch copying using silicone quick molds. The life of silicone molds is very short, only about 10-30 pieces! It has good flexibility And copy performance. Since the current mainstream way of making prototypes is CNC machining and 3D printing, the silicone quick mold is still not known by too many people. Here is a detailed introduction to the production of the silicone quick mold.
 
1. Making a prototype: Before making a quick silicone mold, a prototype must be made. This prototype can be made by CNC processing or 3D printing.
 
2. Preparation materials: component A is rubber, component B is catalyst, when the room temperature is 20-25 degrees, A:B=100:1.5. When the room is low (but not below 10 degrees), add 0.1-0.3 parts of B component. If the room temperature is too high, 0.1-0.3 parts of group B will be reduced.
 
3. Making the mold: Put the prototype into the corresponding container, pour the prepared materials into the clean prototype to be imitated, and it can be cured into an elastomer in 2 hours at room temperature and 20 degrees. be usable. At this time, you only need to take out the silicone quick mold, and then cut along the predetermined parting line to take out the prototype. After the silicone quick mold is completed, you can use it to inject, that is, use the silicone mold to replicate For prototypes of other plastic materials (such as abs, pc, acrylic, etc.), the following is the injection process.
 
Step 1: Use CNC, SLA, or 3D printing to process the prototype and make the nozzle
 
Step 2: Enclose the prototype with a board to prepare for the mold
 
Step 3: Pour the liquid silica gel vacuumed with a vacuum machine into the mold to cover the product
 
Step 4: Put the mold into the oven and bake, so that the silicone mold can accelerate the curing and forming
 
Step 5: Take the prototype out of the mold
 
The sixth step: According to the materials required by the product, vacuum and pour the material to copy the finished product
 
The above is the relevant knowledge of silicone quick mold, I hope to help you.
