Essential for extrusion resin (plastic) molding: Edge controller for automatic take-up machine (extruder rotation speed) control device.

Introducing the hit product in the resin extrusion industry, the "Edge Controller." 【Features】 - Labor-saving through reliable cost reduction via automation - Stable quality - Capable of consistently extruding unstable resins that could only be drawn manually until now The sensor captures changes in the shape of the extruded resin and automatically controls the take-up machine speed (or extruder rotation speed). The sensor is set in the air gap between the extruder and sizing. It is compatible with any take-up machine or extruder. Since control can be achieved simply by observing the edges of the molded products, it can handle not only simple shapes like flat plates and L-shapes but also large products and those with complex cross-sections. *About the terminology While major electronics manufacturers describe the "Edge Controller" as a device for collecting data, ETEX Corporation's "Edge Controller" is a device that controls the edge to a target value. It is used in the same sense as devices like "temperature controllers," "flow controllers," and "pressure controllers," which control physical quantities to target values. It is not a device for collecting data.

Applications/Examples of results

General Extruded Resin (Plastic) Molding Products In the case of extruded resin profiles, it is possible to control the position of the edges where the mold is released, ensuring that the overall width, external dimensions, and shape of the profile remain consistent. - If the edge position bulges outward, increase the speed of the take-off machine or decrease the rotation speed of the extruder. - If the edge position sinks inward, decrease the speed of the take-off machine or increase the rotation speed of the extruder. We have various achievements in products such as surface boards, batten boards, wood powder-filled molded products, lighting covers, air conditioning ducts, skirting boards, wiring ducts, protective tubes, and recycled flooring boards. Depending on the molded product and situation, various sensors (resin pressure sensors, reflective lasers, transparent body lasers, etc.) can be utilized for control. - For general foaming and rigid products, the take-off machine is controlled. The take-off speed is automatically fine-tuned (approximately 0.001 m/min increments). - For soft and wood powder-filled foaming, the extruder is controlled. The rotation speed of the extruder is automatically fine-tuned (approximately 0.01 rpm increments). Please consult us for more details on which control method for the take-off machine or extruder is preferable.

Detailed information

The sensor set can be easily installed by fixing the L-shaped bracket to the edge of the tank with a C-type clamp (shacko-man) as shown in the left figure, and simply placing the detection unit on it.
