Paragon Plastics manufactured this featured manhole inflow dish out of a combination of HMWPE material. Using a customer supplied print, we loaded a sheet of 31" x 31" x 0.180" black HMWPE into our mold and used a female draw to form the sheet to the full detail of the mold. We removed the formed part and allowed it to cool for 3 cycles. Once cool, we used a #10 drill bit to drill a hole for the nylon strap and then routed the perimeter of the dish. We riveted the strap to the dish using a #64 large flange rivet and a 1/16" x 1" fender washer.  Once manufacturing was complete and the part had been inspected for defects, we finished assembly by installing a rubber gasket around the perimeter. The final dish measured 25.25" in outside diameter and 5.47" in height. To prepare the order for delivery, we then stacked them in groups of 25, with 100 dishes per each 48" by 48" pallet. Each pallet was then packed in a 48" by 48" cardboard sleeve and tightly shrink-wrapped. A tracer tag was attached to each completed pallet, and we shipped the order to our client.

Our careful attention to customer specifications combined with our forming expertise resulted in a superior product that surpassed our client's high standards. To learn more about this project or other Paragon Plastic services, please contact us.
