There are many ways to produce plastic products, and vacuum injection molding is one of them. Today we are going to present its characteristics.
Vacuum injection molding is a technology for making replicas, also called vacuum molding. Generally, 3D printing, CNC processing and other methods are first used to create a prototype, and then the prototype is used to make a silicone mold or a rubber mold (currently mainly). silicone), then inject the liquid material into the vacuum mold and harden it.
The general process of vacuum injection molding is as follows:
1. 3D printing or CNC processing to produce a prototype;
2. Fix the prototype on the wooden board, then use other wooden boards to make a 5-sided sealed wooden box mold;
3. Prepare silica gel and pour it into the wooden box mold;
4. The wooden box mold is left under vacuum for a period of time, then placed in an oven to accelerate solidification;
5. After curing, make an incision on the silicone mold and remove the prototype;
6. Seal the silicone mold and put it into the vacuum injection molding machine;
7. Prepare the resin material and put it into the vacuum injection molding machine;
8. Stir the resin under vacuum and inject it into the silicone mold.
9. Take out the silicone mold and put it in the oven to accelerate curing;
10. After curing, open the mold and take out the product;
Advantages of vacuum injection molding:
1. The production cycle of silicone molds is much shorter than that of metal molds (used for injection molding).
2. The production cost of silicone molds is also much cheaper than that of metal molds.
3. Very suitable for small batch production of 1-20 products.
Disadvantages of vacuum injection molding:
1. Silicone molds generally can only be used about 20 times.
2. The precision is slightly lower than that of CNC machining and injection molding.
3. The materials that can be used are relatively limited.
