Plug Machining: J&R Plastics takes plug assists to the next level. Cast plugs simply are not good enough. We go the extra mile to achieve plug perfection. All our plugs are cad/cam designed and CNC manufactured to ensure repeatability and true mold geometry. 

We feel that precise manufacturing of each and every component of your thermoforming tool makes for faster setups, quicker run times, increases your profitability, and delivers the highest quality product possible.
