Production of plastic parts with vacuum castingPrototech
The use of vacuum casting technology instead of CNC machining is justified for production quantities of more than 5 or 10 identical parts and this technique is very competitive for the production of these small series of plastic parts, in particular, compared to 3D printing or CNC machining.
The production of prototype parts by the vacuum casting method (also called vacuum duplication) is done in various phases.
Step 1: Creation of the master model. This model can be manufactured by various methods such as CNC machining, 3D printing or stereolithography.
Step 2: Creation of the silicone mold(s) with the master model. One mold can be used to produce approximately 5 to 20 parts (depending on the shape of the part and the material used).
Step 3: Finishes. Once the prototype parts have left the silicone mold(s), they must be processed individually to make them conform to the specifications (adding paint, polishing, mirror polishing, etc.).
Vacuum casting is, therefore, the reference method for producing small series ranging from 10 to 150 parts, because it is competitive with other prototyping technologies, offering a wide range of materials and a very good quality of finish.
These materials are found in the catalogs of our suppliers Axson and Heisen Yoko. This allows us to offer our customers all the most commonly used materials, such as PU similar to ABS, PP, PC, MPMA, POM or PA6.
We also have materials possessing specific properties, such as UL94, or transparent, flexible or food-grade-certified materials.
