Demag / Van Dorn Solution

01 / 03

JVH Engineering has designed a controls platform utilizing Rockwell Software® and an Allen-Bradley CompactLogix® system. This platform has been used to create a predesigned solution for Demag/Van Dorn injection molding machines. These tested solutions use the most up to date Allen-Bradley® technology along with customer specified Rockwell Software® to allow for ease of use. All our solutions are designed with the intent of delivering a turnkey control design that allows for full customer manipulation.

Due to age and advances in technology, control systems on Demag/Van Dorn’s are obsolete and out of date. These old systems make operating and maintaining such a nightmare for customers that they are usually left contemplating between fixing or replacing these machines. That is where the JVH Engineering controls solution come in. Purchasing this solution will fix the original flaws of your machine, while receiving full service and support from JVH Engineering on all controls needs.

Our solution is comprised of a full control upgrade as well as an optional servo valve replacement. The new cost-effective proportional valves will deliver fast, smooth, and quiet machine operation. Upgrading from the old control system to a new CompactLogix system will also improve barrel and mold temperature response, creating a more repeatable production process.


  • Ethernet Communication

    Faster machine communication and full machine connectivity to data collection systems.

  • Allen-Bradley VersaView®

    Touch screen HMI equipped with a solid-state hard drive.

  • Digital Sensors

    Digital position sensors for more accurate, noise free, repeatable position control with instantaneous velocity feedback.

  • Process Logging

    This feature will allow for reduced setup time by saving every process while also allowing for process comparison.

  • Part Consistency

    High response injection control for exceptional part consistency by adding a new 10 segment injection fill velocity profile, 5 segment ramped hold profile, and 3 segment recovery profile with closed loop backpressure.
