Vacuum casting
This technology is generally preferred for obtaining small or medium-sized parts with significant areas of detail. In addition to the low cost and short lead time for this type of tooling, this technology also has the advantage of being less restrictive in terms of geometry: variations in thickness and undercuts allowed. The wide range of PU resins available makes it possible to get as close as possible to the final thermoplastic in terms of rendering (mask-tinted opaque, transparent crystal or mass-tinted), mechanical behavior (rigid, semi-rigid, flexible), thermal resistance or fire classification (UL 94 V0). This technology therefore makes it possible to obtain small series of parts offering excellent representativeness of the final product. Silicone tools for vacuum injection have a lifespan ranging from 15 to 30 duplications, depending on the resin used and the geometric complexity of the part. Combining the possibility of identically reproducing a particular surface aspect (texture, mirror polish) with that of using a mass-dyed polyurethane resin, this technology can represent, depending on the quantity to be produced, a competitive mass production alternative.
