The channel is set up in such a way that an extremely large heat transfer from the air to the rubber profile takes place in the first channel zone, so that the surface can be heated up and vulcanized as quickly as possible.
Optimally they are gas heated and the temperature of the process air can be set up to 400[degrees]F (248[degrees]C).
Standard and special runnerless molding systems and components include hot manifolds, complete bolt-on systems prewired and tested, integrally heated probes, hot-sprue bushings/nozzles, two-stage externally heated nozzle filters, thermocouples, and hot-runner temperature controls.
Modular manifolds integrally heated with replaceable thermocouples and made of tool steel.
Also minimum-pressure-loss filter nozzles, directly heated machine nozzles, and water-cooled gate inserts for use with company's nozzles to maximize gate-area cooling and shorten cycles.
Extensive range of single-feed hot-runner nozzles and multifeed bushings includes internally heated bushings based on thermocouple-controlled 24-v cartridge heaters; externally heated sensitive materials; multitip bushings with up to eight independently controlled tips within one bushing body; patented valve-gate bushings; and hybrid nozzles, which have been supplied up to 1300 mm, combining the gate-vestige control of the 24-v thermocouple cartridge bushing front section with low-pressure drop of the extended length rear section open-flow bushing.
Temperature controllers suited to run firm's 24-v internally heated bushings and most 240/480-v systems.
The drops on these systems are heated and boast flow paths free of restrictions, resulting in faster start up, cooler operation and energy savings.
Runnerless molding systems consist of hot-runner manifolds, heated sprue bushings, multitip nozzles and temperature-control systems.
Heated sprue bushings of six different tip styles in 1 1/2-, 1- or 3/4-in.
