• Sleek designs hinge on strong rotary joints
  the rest of the pack. One such alternative technology is metal injection molding (MIM). It is increasingly adopted to fill the niche where other metalworking processes are not viable. Typical examples are in miniature components such as rotary hinges found in cell phones, PDAs, laptops, tablet PCs...
• Micromolding Sizing Up the Challenges
  , these high-performance miniature parts often require engineering materials like polyamide-imide, liquid-crystal polymer, polyetherimide, PEEK, PPS, and new cyclo-olefin (COC) resins, in addition to more standard ABS, nylon, acetal, and TP polyester. Many jobs also involve fillers like PTFE, Kevlar, carbon...
• Simulation Shows How Silicon Solidifies
  Belle Vernon, Pa., used FEA software for a combined transient heat-transfer and CFD analysis that let the company reshape the hot zone of its "minicaster" -- a miniature version of a directional solidification furnace that casts silicon ingots used in solar cells. "The furnace's small size lets us...
• PLASTICS REFERENCE GUIDE
  miniature hand extruder contains a plasticizing unit, hot-air blower, rod feed, and electronics in one package. The compact tool from the Swiss firm Leister Process Technologies and distributed in the U.S. by Uneco Systems Inc., Romeoville, Ill., requires no additional booster and weighs only 2.8 kg...
• Polymers protect printed paths
  is removed or diminishes, the PPTC cools, switches to the low resistance state, and the circuit resets, ready for another protection cycle when needed. It should be no surprise that circuit-protection devices for miniature and handheld products such as cell phones, laptop and palmtop computers...
• Cable Carriers
  . Cable carriers come in a wide range of sizes and carrying capacities. Among the smallest is the igus E04 "pico," a polymer carrier with an inner height of 0.26 in. and an inner width of 0.28 in. Typical applications are those involving miniature power supplies as used in sensitive measuring equipment...
• Auto Parts Maker Meets Tight Production Deadlines and Improves Quality Assurance Practices with ShapeGrabber
  with ShapeGrabber. Resource Centre. Customer Stories. Auto Parts Maker Meets Tight Production Deadlines and Improves Quality Assurance Practices with ShapeGrabber. Customer. MPC Inc. Walworth, Wisconsin, United States. Background. Miniature Precision Components (MPC) Inc. supplies major automotive...
• Spring Manufacturing using Ultem
  ". The engineering team at Dynacept has developed a process where Lee Spring can provide the specs of their desired spring design and the team at Dynacept can then design and mold the parts in a streamline fashion. This was then applied to a miniature spring design that required a modification...
• Metrigraphics Article in Today's Medical Developments
  adds. Induction coils eliminate batteries. Micro-induction coils can be used in a variety of medical applications including miniature loop antennas for both active and passive implanted devices, sensors, and neurostimulators. Induction coils from Metrigraphics are equipped with radio-frequency signal...
• Epoxy
  . Printed-circuit boards, consisting of a glass-fabric-reinforced flame-retardant epoxy resin are another major use. Filled and unfilled liquid systems are used for potting and encapsulating electrical/electronic components ranging from semiconductor devices and miniature coils and switches to large...
