Transparent Plastic Prototype
On the product development, normally we would like to make plastic prototype to prove our design work or not, also this process can prevent additionalmodification cost thanks to that we know if the product design is correct or not before mold making.
As the technique progress, there are a few solution to make the transparent plastic prototype before mold making, today we will suggest two solution here.
CNC machining transparent
One is CNC machining process, it is to use the CNC maching process to manufacture transparent prototype, normally the PMMA resin will be the best workpiece, please kindly reivew our post” PMMA maching prototype”. There also is possible to manufacture PC and ABS resin, but on the process, both PC and ABS polishing performace are worse than PMMA resin.
Plastic casting process to make transparent plastic prototype
The other is process as a tool to make the silicone rubber mold for plastic casting process. For this process, you can review our plastic casting post to understand more. We also should be noted that the surface finishing of the plastic casting depend on the silicone rubber mold, normally it is also diffcult to get very good gloss surface for transparent on the plastic casting prototype making process. Also we can use the simple aluminum mold instead of silicone rubber mold on the plastic casting, but this can be used on when we need prototype more than 100 pcs etc.process, it is to use chemical liquid resin(silimar as PMMA, PC or ABS etc) to solid in silicone rubber mold. To use the plastic casting process to make the transparent plastic prototype is cheaper than CNC machining processs, but before plastic casting, we have make out of the first of prototype by using CNC machining, SLA or SLS
Transparent plastic prototype polishing.
As a summary for above, regarding the transparent plastic prototype making, if we need very gloss surface finishing transparent plastic prototype, we have to go with CNC machining and fine polishing, if need cheaper plastic prototye and more than 5pcs as well as we have not high quality on the transparent surface, then we can go with plastic casting.
