Valve Gate systems, designed with robust and compact cylinders, offer superior performance and gate quality with both hydraulic and pneumatic actuation available on INCOE DF Gold hot runner systems.

Direct Mount Units
Actuation cylinders mount directly onto the manifold making it unnecessary to remove the valve pins before removing the entire system from the mold. Valve pin adjustment is simply accomplished without hot runner system dis-assembly.

Integrated Compact Design
The direct mount feature also allows INCOE DFQ hydraulic Valve Gate systems to be supplied as a completely self-contained unit, both pre-plumbed and pre-wired.

Clean Room Ready
Pneumatic DF Valve Gate systems are ideal for clean room molding applications such as medical disposables.  Zero gate vestige and pneumatic actuation allows consistent and rapid closing of the valve pin, complimenting part weight and dimension requirements.

Sequential Molding
Sequentially controlled valve gated systems are often necessary to achieve ideal part quality in large part applications. Precise control operation of the valve pin ensures exact, repeatable filling; part after part. INCOE offers 2 controller designs including:

GSC2 -Gate Sequence Control. For more information,

SoftGate Valve Pin Velocity Control for Sequential Molding 
The SoftGate system is an enhanced feature that precisely controls the opening phase of the hydraulic actuated valve pin. This allows for the “gentle” flow of plastic into the cavity eliminating blemishes that can occur with uncontrolled plastic flow. Components consist of a flow control module for adjustment of pin opening, valve pin position monitor, and a timer to display pin open time which are added to our INCOE hydraulic valve gated hot runner system. SoftGate can also be retrofitted to your existing INCOE hydraulic system easily. For more information on SoftGate

Nozzle Design
DF Gold Systems can utilize either our threaded DFQ series of nozzles, or our compression fit DFX nozzles.

Shot Weights
6 nozzle sizes process from <65g up to 5900g shot weights. Nozzles are identified by runner/channel sized in mm as follows:

Nozzles Shot Ranges
DF5     (5mm channel)
<65g
DF8     (8mm channel)
30-375g
DF12   (12mm channel)
140-1050g
DF18   (18mm channel)
420-2600g
DF25   (25mm channel)
900-5900g

 

Valve Gate Performance Features:
•    Zero gate vestige
•    Cycle time reduction by fast filling and only partial use of hold pressure
•    Elimination of freezing, stringing or drooling of gates at start up or interruptions
•    Lower melt stress and low part distortion
•    Elimination of weld lines when used with Gate Sequence Control GSC2. DF Gold systems only.
•    Elimination of wrinkles in substrate in back-molding applications with GSC2. DF Gold systems only.
•    Balanced filling of different size parts in family molds
