HCR cold deck with FLOWSET

The company

The Promed Molded Products company offers a wide range of products for medical and pharmaceutical applications. Nexus has reduced the cycle time by half with a state-of-the-art cold deck customized to the customer's material.

Initial situation & challenges

With an injection molding machine from Arburg and an HCR cold deck with outdated technology, Promed Molded Products previously processed 65 durometers of HCR raw material. Over time, too small flow paths, the lack of a balancing system and pressure drop in the cold runner led to a restricted process window. This brought severe cycle time and speed limitations as well as frequent cleaning cycles. The challenge in the project was to build a cold deck suitable for the existing mold.

Optimal operation thanks to optimal conditions
Professionalism to the last detail

Optimal operation thanks to optimal conditions

In close cooperation with the customer, a Nexus HTV cold runner with Flowset Electric balancing system was added, which reduced the injection pressure enormously. The controllability of the flow can now be regulated and optimized in each cavity. Cleaning time and the amount of deposited material in the cold runner have also been cut in half thanks to the new Nexus solution. Short communication paths and in-depth experience with different types of material make Nexus a highly qualified partner.

Despite difficult conditions, we found an optimal solution for Promed Molded Products - with improvements on all levels!
