Automatic water flow control

              There are many advantages that come from plumbing a tooling’s cooling lines in parallel. However, many molders often find this impractical because to do it properly one needs a flow regulator installed to balance the flow. This adds cost, complexity to the setup, and maintenance to the process, but can bear great fruit in terms of cycle time improvements and process consistency. The future is an automated system, integrated into the molding machine, running in the background of your mold set up. The flows and temperatures are set when the mold is qualified, and now those settings follow the mold wherever its program goes. That future is here now with the Flowcon Plus automatic flow regulator. The key advantage of this type of flow regulator over a manually adjustable one is that it permits continuous electronic monitoring of the preset flow and temperature values. All data are logged and can be automatically adjusted proportionally via control valves. The proven WITTMANN 301 Series fine regulating valve performs the flow regulation function. Generously dimensioned channels in the casing blocks guarantee the lowest possible pressure loss and high flow rates. The net benefit is being able to easily manage parallel plumbing of your cooling channe-ls, balanced temperatures and flows throughout the mold, or zoned temperatures if you need them. This leads to a much higher level of process repeatability. Working with a multi-cavity tool? No problem - automatic flow regulation ensures uniform cavity filling due to a consistent heat profile throughout the mold and it’s cavities. Lastly, if there is degradation in flow due to a blockage, the system will identify this, its location, and indicate to the operator that there is a problem. This allows a technician to proactively clean a cooling channel before a failure occurs.
