Vacuum replica molds use polyurethane, transparent polyurethane, ABS and other materials to cast the same replica mold as the product prototype under vacuum to achieve the strength and hardness of ABS and other materials. It can also be copied together according to the color required by the customer.

It is fast and low-cost, solving the cycle and cost problems of new product development. Generally speaking, the quantity of prototypes required by customers is not very large, usually only a few or so. And the precision requirements for the hand plate are not very strict, so the best way is to use a vacuum mold. This is also the reason why many customers choose vacuum molding.

The process flow of silicone replica mold:

1. Prototype

Prototypes can be models or parts made of various materials, such as plastic, resin, metal, etc. After the prototype is made through CNC processing or 3D printing, make sure the surface of the model is clean, dust-free, and free of oil stains.

2. Make silicone mold

Mix the silicone base material and curing agent evenly in proportion, and slowly inject from the top or side of the prototype to ensure that the silicone fills all details and voids around the prototype. After injection, gently shake the mold frame to expel air and ensure the silicone is evenly filled. Then after a period of curing, the silicone mold is ready.

3. Release from the mold

Depending on the curing time and hardening conditions of the silicone, wait until the silicone is completely cured and hardened. The exact time depends on the type and thickness of silicone. This may take anywhere from a few hours to a day. Once the silicone has completely cured, carefully peel the replica away from the original model. For some tightly adhered parts, you can use appropriate tools to tap lightly.

4. Small batch copying

  Once the silicone mold is ready, you can start using it for replication. Pour appropriate materials (such as resin, wax, etc.) into the silicone mold. After the material solidifies, take out the copied parts from the mold and make small batch copies. After these workpieces are demoulded, you can perform surface treatment, such as polishing. , polishing, etc. to obtain a smoother surface effect.

  Silicone mold processing has a wide range of applications:

     Medical equipment smart home digital accessories

     Photographic equipment, beauty equipment, various buttons

     Various handicrafts, scanners, office supplies
