Easier to work with in confined spaces.

A new clamping system for hot-runner nozzle heaters is said to allow easy installation in tight spaces. Attachment of nozzle heaters is usually by means of a screw and a wedge mechanism. Clamping with this approach reportedly can be quite difficult in small, compact hot-runner blocks with narrow tubular channels, or when the heaters are mounted one behind the other on the nozzle.

A solution introduced by Turk + Hillinger (U.S. office in Brecksville, Ohio), at last month’s Fakuma 2014 show in Germany involves a new sliding and wedge mechanism that allows the heater to be simply pushed onto the nozzle core and secured axially by moving the wedge.

    U.S. injection molders are still pretty green when it comes to processing the new crop of renewably sourced biopolymers. These biologically derived polymers made from PLA, PHA and starch-based resins are attracting growing market interest as materials with no ties to petrochemical-based thermoplastics.

    If you’re interested in lightweight composites, IML, LSR, multi-shot, inmold assembly, barrier coinjection, micromolding, variotherm molding, foams, energy-saving presses, robots, hot runners, and tooling—they’re all here in force.

  • The New Dimension in Mold Simulation

    Keep an eye on the increasing prominence of so-called “3D” mold analysis. Two vendors of simulation software from Europe and Asia think it’s the best solution for a big proportion of injection molded parts. Established U.S. suppliers aren’t so sure. In any case, the capabilities of both 3D and standard 2.5D simulation are expanding rapidly.
