DF GOLD SERIES

INCOE® Direct-Flo Gold hot runner systems are designed for use in technical molding applications using engineered resins. Based upon the previous generation of proven and reliable hot runner technology (the DF Series), the DF Gold series is an innovative refinement of the technology providing increased hot runner performance and robustness while maximizing molder up-time. DF Gold Series features include: Twin Heater – The Twin Heater incorporates two separate heating circuits in each nozzle heater. This redundancy provides for uninterrupted production if a single heater circuit failure should occur and allows for easy replacement during a planned maintenance period. A second heater thermocouple can also be added to provide another level of redundancy to the system. Heater dimensions remain consistent compared to the previous generation heater, allowing for simple upgrades for previous generation hot runner systems. Gating Configurations – Several tip designs in thermal tip, sprue and valve gate offer increased flexibility for any application. All tips utilize a proprietary coating that yields increased wear resistance. Color Seal – A final solution for troublesome color change issues. Often color change can simply be performed by increasing melt temperature while purging the system. However with some materials the color to be removed often can stay within the gate well area and continue to “bleed” through to the new color, creating defective molded parts. The introduction of the new Color Seal traps the material and can easily be removed between color changes.

BACK-TO-BACK VALVE GATE

Compact yet functional designs are a necessity for stack mold applications. Common valve gate designs require the cylinders that operate the valve gate to be off-set in order to reduce stack height dimensions. Still this design generally results in larger molds and perhaps injection molding machine size. INCOE®’s back-to-back design eliminates the offset requirement while making no compromise in stack height and presents the potential for cost savings in mold construction.

DMT5 MICRO MULTI-TIP

Miniature size molded parts require extremely close nozzle placement within the mold. INCOE®’s DMT5 Micro Multi-Tip can have 2 points as close as 13mm, and up to 6 points on a 26mm circle.

M-SERIES TEMPERATURE CONTROL

The M-Series hot runner temperature controller offers technology second to none, such as the continuous self-tuning feature. The M-Series control utilizes the well known Windows architecture, making operation of the control easy to learn and use. Operator input can be achieved by touch screen PC or Lap Top; and is also equipped with a keypad in the event of computer failure the operator maintains the ability for input. The control is modular in construction offering 16 to 128 zones as standard. INCOE® works with SISE as our exclusive supplier of computer based hot runner controls.

MULTI-PIN VALVE GATE

Typical valve gate designs require large pitch dimensions in order to accommodate the cylinder device that operates the open/close action of the valve gate. INCOE®'s Multi-Pin Valve Gate provides for up to four pins contained within a single cylinder mechanism easily accommodating small dimensioned molded parts. As molds can then be manufactured in a more compact size cost savings are realized.

TWIN HEATER

INCOE® strongly believes a major factor in the performance and reliability of hot runner systems relies upon heater quality, and therefore has always supplied a proprietary in-house manufactured heater. Molders are under enormous pressure to deliver just in time parts to their customers, while at the same time keeping spare parts inventory at a low level. Thus any interruption of production quickly can lead to a disastrous result. In our effort of continuous improvement, INCOE® is introducing the Twin Heater. Unlike other systems available where two independent heater coils are wound on the nozzle body, the Twin Heater eliminates the possibility for proper heat profiling by combining two heating elements in one nozzle heater coil. The outside dimensions of the Twin Heater are absolutely identical with the former INCOE® nozzle heater and therefore interchangeable. The second heating wire provides for the continuation of production if a failure should occur and as such eliminates downtime for heater replacement during production. Failure of one heating circuit is clearly shown on the temperature controller by the output value of the respective control zone. Production is uninterrupted, even if the malfunction of the heater is not recognized by the operator. Thus the highest level of production is guaranteed.

PRODUCT RELEASE

One of the essential factors for the injection process is uniform temperature profile in an injection mold. This has a direct and basic influence on the cycle-time and the quality of the molding. Using a hot runner system results in an elevated temperature in the gate area of the mold. Heat at processing temperature is transmitted over the contact areas from the hot runner into the mold. In general, temperature difference between hot runner and mold is approximately 200°C. If the gate area is not sufficiently cooled, defects and surface quality problems will result. Altering the cycle to attempt remedy yields negative economical conditions or increased rejects. Elevated temperature may also cause valve gate pins to stick to the molded part. The pin is only in contact with the mold during cooling time and ejection of the molding. During this period of time, it does transfer temperature to the mold allowing cool down. During the injection phase the pin is inside the flow channel surrounded by hot plastic material. In these cases, intensive cooling of the gate is located as close as possible to parting line. Up to now, such cooling could only be realized with complex gate inserts, which are complicated to install into the mold. The patented cooling insert, developed by INCOE®, combines optimal cooling of the gate with minimum effort for the mold maker. The cooling medium passes through the very front areas of the gate insert and effects turbulent flow thus effecting optimal cooling. The boring details accommodate simple mold installation.
