Actually our factory did prototypes for more than 10 years, and our parts export to European and USA market for long years. We do injection molds and plastic parts also, all the details you can find from our website: We do prototypes by 3 ways normally: 1:CNC normally many kinds of material we can do: ABS, PC, PA, PP, PMMA, POM...after the parts milling, we can do painting or silkprinting. 2: Si-mold We will do a silicone mold first, and the duplicate the parts. 3: SLA or SLS For some complicate construction parts, we will use this way normally.
