Hot Runner Mold

Hot runner solutions have been utilized in various plastic injection molded products. Such as bumpers, automotive instrument panels and LCD/TV panels. Advantages hot runner molds bring include material and energy cost savings and shorter cycle times, for the runners that are eliminated in the process. However, hot runner systems are comparatively more complex and commonly face the challenge of elaborate temperature control and the risk of thermal degradation of plastic materials. Hot runner systems are feed systems for injection molds which convey molten plastic from the machine nozzle into the cavity.

Molders and mold makers require tooling solutions that are reliable, minimize variability and improve production efficiencies for the most complex applications. Our hot runner solutions meet the needs of today’s production requirements by optimizing the entire melt delivery system, ensuring the best gate quality, cavity-to-cavity balance and fastest color changes.

POWSTAR understands your production requirements at a tooling level. By taking parts first approach we can optimize your hot runner for each application, helping you bring products to market faster and at the lowest part cost.
