A machine shop first. We CNC mill and turn custom parts in engineered plastics, plus aluminum, brass and bronze. We also supply plastic sheet, rod and tube, cut to size, when you need material rather than a finished part.
Upload drawings, CAD files or photos with your quote request, or email them to sales@cdsplastics.com. If you only have the part itself, our reverse engineering page explains how to get it to us.
We hold ±0.002" to ±0.005" on critical dimensions, depending on the plastic. We review your drawing and confirm the critical dimensions with your quote.
Yes. Part specifications and CAD files are kept on file, so a reorder only needs your part number and anything that’s changed. Use the reorder form or call the shop.
