Hot Runner System

hot runner system
The hot runner system is one kind of new injection molding system, it controls and maintains the melt plastic to arrive at the die space directly from the injection molding machine main feed inlet under the appropriate condition.
Yichuan series preform injection mold adopts specially designed hot runner system to achieve ideal and prompt heating effect for preform production. Lager flowing channels of such hot runner system ensures the mold to produce preform with lower injection pressure, which reduces mold’s each part’s wear & tear and maintenance cost, and also saves electric energy.
Hot Runner System Description
Fast cycling due to specially designed cooling circuits.
Standard interchangeable mold components; replacement parts available within 72 hours.
Rugged design for long life.
Auxiliary tapers that reduce mold wear by pre-aligning the mold halves prior to the engagement of the neck ring tapers.
Roller cams that actuate both the opening and closing actions on the thread splits.
Lowest cavity-to-cavity weight and dimensional variation as a result of best-in-class manufacturing machinery and processes.
Water hoses that are manifolded at the bottom of the mold, eliminating potential for water marks on preforms.
Hot Runner System Features
Shorten the processing cycle, raises the efficiency
Replaces the cold runner, thus does not produce the crude material, does not need to crush again.
Enhances the product uniformity, improves the product quality.
Improves the gate outward appearance.
Reduces the product aberration quantity, reduces the product distortion.
Uses the valve gate, injection molding step-by-step,produce different specification size the components series.
Enhances the more processing process control, in order to make the precise adjustment to the injection molding.
The hot runner system is composed generally by three parts: main feed inlet, hot divergence board, hot spray nozzle. Sometimes the system includes the cut-off valve, uses in closing the runner, improves the product surface quality, permits using the large gate.
