1. Introduction.

VCM type vacuum injection mold process, it is using the original model, the silicone mold was produced under the vacuum state, and casting in vacuum using PU materials, thereby to clone the same copy with the original sample, is one of the most commonly used rapid tooling technology, through this technology, can produce various features of similar engineering plastic products, At the same time can be small batch production.

2. The process flow

Take the small batch trial production of car lights as an example:

3. Advantages of VCM vacuum injection compound mold process

※ One set of rapid die can produce 20~30 sets of products.

※ The surface of the product is fine, which can meet the purpose of appearance design verification and structure test.

※ Compared with the traditional small batch production after mold opening, the cost is reduced by more than 70%.

4. Application area Due to the low precision and resolution of the products formed by the VCM vacuum injection compound molding process, it is suitable for forming small plastic parts, which is suitable for the needs of simple testing and conceptual design.
