  • Give cylinder-rod contaminants the boot
    . Injection-molded bellows offer complete sealing but present several disadvantages. For instance, mold costs are usually too high for retrofit applications. And even if stock-molded bellows are available, the material is unsupported and can tear easily. Also, the rounded convolution shapes usually provide low
  • Viscosity Matters
    temperature and ethylene glycol (a common antifreeze compound) on kinematic viscosity. Figure 1. Figure 2. Consider this example. For a ½" dia. flow passage in a mold with water at 60°F, it takes about .5 GPM to get turbulent flow. But what if you are using a coolant of 30% ethylene glycol in water
  • Advancing the art of moldmaking
    are more accurate due to less thermal expansion and contraction, and it far outlasts aluminum. Laminate molds also let designers place cooling lines where they are most useful. Heat conducts from the molten plastic to the mold and is then removed by coolant flowing through a network of internal
  • Case Study: Components - How to Make 'Quick-Turn' Your Shop's Mantra - 12/06
    Machining Trends for Drilling Coolant Channels in Mold Bases How to reduce the costs and leadtimes associated with mold base manufacture by using multi-functional machines. the MMT Showroom for AIMMco There's no mistaking it, turnaround time and speed-to-market is increasingly imperative
  • Medical Device Link . Innovative Injection Molding Techniques for the Medical Industry Four molding techniques open up a variety of new approaches to the design of medical components.
    . In the conventional molding process, coolant such as water or oil is circulated through the mold continuously while mold temperature is regulated by a controller such as a thermolator or chiller. This type of temperature control maintains a reasonably consistent water-inlet temperature to the mold
  • Thermal Imaging to Gauge Cooling Efficiency in Injection Molding
    , the cooling cycle would be reduced. to 48 seconds, almost a 30% reduction. If the wall remained 3.5 mm and the coolant/mold temperature. was reduced to 20°C the cooling cycle would then be 46 seconds. The information outlined in the table below is required to establish a baseline cooling cycle: Part
  • Polyimide composites challenge metals
    to have a wider scatter of tensile and bending strengths. To combat lower surface tensile and bending strengths a layup technique can mold a single ply of fabric onto the clamp surface. The additional fabric reduces expansion in the Z-direction and also helps damp vibrations. Composite clamps can
