Inquiry (采购产品): Rigid Tubing I need a source for a plastic ring to hold an Oxygen Tank onto a vacuum formed part which we make. The ring dimensions are: 4.75" ID x 5.062" OD cut into 2.00" +.03-.06 rings. We currently vacuum form these, then cnc cut them and drill four holes. Due to the zero draft, it is a bad job for vacuum forming, with high scrap and long cycle tiem. Volume is 500 - 1,000/year, but we may buy multiple years worth. The preferred color is light gray, but we will most likely paint these. Please offer your proposal. Feel free to call me, Cam Streidl c/o Thermoforms, Inc.
