Pre-engineered, standardized hot-runner systems and components include temperature controllers, torpedoes, sprue bushings, probes, thermocouples, modular and integral manifold system, and patented hot sprue bushings and gating bushings that use standard cartridge heaters but equalize the temperature profile to make it suitable for processing engineering resins.
Full spectrum of runnerless molding systems: hot tips to valve gates, multiple gate nozzles to hot sprue bushings, prewired manifolds to complete hot-half systems.
Runnerless molding systems consist of hot-runner manifolds, heated sprue bushings, multitip nozzles and temperature-control systems.
Fixed renewable (ANSI F) - Used with bushing liners on part runs longer than typical bushing life and held in place with a lock screw.
Slip fixed renewable (ANSI SF) - Used with a bushing liner (headed or headless) permanently pressed into the fixture, locked in place with a lock screw or as a slip lock to permit more than one operation to be performed at the same hole, such as drilling and reaming, without disturbing the workpiece.
thick magnesia lining between the channel and the bushing suggests that the saturation network would be limited to a depth of about 1.66 in.
How close to the bushing will the saturation network get before freezing is a function of the heat extraction capabilities of the bushing.
