Petaluma, Calif., and its customer Palo Alto, Calif., won MIM grand prize honors for a high-compression jaw used in a device for laparoscopic vessel fusion. Top and bottom jaws, an anchor, and an I-beam are made of 17-4PH metal powders sintered to densities of over 7.6 gm/cm3. The parts sport thin walls and highly complex geometries that would be difficult to produce economically by other methods. The I-beam is the cutting mechanism. High compression is maintained as the blade advances from the proximal to distal end of the jaw. The system also incorporates smart electro-technology to rapidly fuse vessels without thermal effects. The Ferrous grand prize went to Commerce, Calif., for a four-part gear assembly. The armature, rotor blank, bearing, and pinion gear operate in a motor drive for automatic minivan sliding doors. The parts have a density of 7.0 gm/cm3, an ultimate tensile strength of 45 kpsi, and a yield strength of 32 kpsi. They are made from a P/M phosphorous iron alloy and they are net shape, except for the rotor that needs a turning operation on the hub. Glendale Heights, Ill., took Stainless Steel grand-prize honors for a complex pump latch made for New Richmond, Wis. The 316 stainless-steel latch attaches to a door handle on a medical infusion pump. It has a density of 6.7 gm/cm3, an 11.5% elongation, and ultimate tensile and yield strengths of 65 and 42 kpsi, respectively. Secondary operations are limited to deburring, tempering, glass-bead finishing, and tapping one hole. The P/M latch replaces a machined die-cast handle that attached to a stainless-steel latch with dowel pins and screws. from Italy took Overseas grand prize accolades for a transmission used in a portable hedge cutter. The six P/M parts (main gear with 51 teeth, two connecting rods, an inner part, spacer, and valve)
Products & Services
Hooks are load-transmitting components that are most often used in conjunction with chains and other equipment. Products are designated as eye hooks, clevis hooks, or grab hooks and are used to connect lifting and rigging attachments.
Turnbuckles are used in rigging to join wire-rope or cable to an anchor point or other length of wire. They have a screw thread to allow for precise length and tension adjustment.
Thread tapes are used to seal, lubricate and prevent seizure on threaded bolts, studs, and fittings.
Rebar is a structural member that is cast into concrete and masonry to provide strength and reinforcement.
Metal sheet is metal or alloy stock supplied or available in the form of sheet or foil. It has a thickness between 0.006" and 0.250", and a width of 24" (609.6 mm) or more.
