Because of our commitment to upholding the highest medical standards, our clients rely on our superior industrial sewing services to fabricate this urethane surgical positioning device for the medical industry. Measuring 46" long and 42" wide, each device weights 7 lbs. and features 2" wide straps. We hold tolerances down to +/- .06", +/- 5°, and a maximum .125" edge distance for welds. This device is manufactured with TPU Urethane & Polystyrene beads.
To fabricate the surgical positioning device, APPF uses a combination of RF welding, industrial sewing, and assembly. We orient and weld 90° valves into position, and weld in a urethane reinforcement patch. We also weld the top and bottom layers together and weld the grommets in place.
We then use industrial sewing to stitch the straps, using black or white thread, making sure the stitching adheres to a 4-point 3-7 SPI pattern. We then sew a buckle to the strap, and sew the strap around the lower inside bar of the buckle.
Assembly requires crimping a suction valve into the open end of the 90° valve. We glue clear tubing into the valve using tetrahydrofuran. We then fill the device with polystyrene beads. Additionally, we screen print artwork onto the devices in accordance with customer specifications.
Throughout manufacturing, we visually inspect each device for holes and tears in the material, and twist all valves 180° to check for tears around the base of the valve. We then ensure the straps are fully stitched to the positioner; we evacuate the positioner, let it sit for 15 minutes, and check for loss of vacuum. Throughout manufacturing, we rely on a combination of machinery for RF welding and industrial sewing, including, but not limited to:
30 kW Thermatron double-shuttle 4-post machine
4 kW valve welding machines
10 kW computer-driven RF machine with an automatic rotary table
Juki programmable sewing machine
AFFP's top-notch machinery allows us to provide RF heat sealing and industrial sewing services that always surpass expectations: our surgical positioning devices are just one example of how our plastic welding continues to meet even the most stringent medical standards.
