I think at first we need the latest scanning technology, because successful application of five-axis inspection also requires the use of appropriate inspection software/program that supports the use of the new probe for the verification of both geometric and free-form shapes on all major makes of CMM. […]
This year an innovative solution offering the advantage of predictable and consistent gate opening found in typical valve gate applications, […]
The first to enter the market and still the most common are thermally operated. […]
Problems with some hot runner technologies are that heat loss through the nozzle can be 40 percent. The heater overheats plastic at the middle of the nozzle. […]
How do you go about evaluating hot runner nozzles? First, evaluate the entire molding system—including part design, plastics material, part weight, cycle time, mold, runner, gates (valve or thermal), nozzles, temperature control and molding machine characteristics. […]
Moldflow Plastic Insight (MPI) is a computer simulation of injection molding that “helps us begin to understand what is going on inside the mold,” […]
Hot runner systems have traditionally used either pneumatic or hydraulic actuation to open and close valve gates. […]
In food packaging, the trend has been toward increasingly thinner walls and higher outputs. To accommodate this trend, […]
When dealing specifically with closure and consumer applications, part and production quality—along with color change performance—are major considerations. Maintaining optimum melt homogeneity is key to achieving this. […]
The manifold is an important component in delivering a consistent and homogeneous melt to the cavity. Today’s industry standard includes naturally balanced melt channels (both with and without level changes), […]
