Industry Challenges

The use of hot runner systems are commonly seen in plastic injection molds and they can be found in various industries from automotive, electronics to medical sectors and more. Hot runner system requires better temperature control to maintain melt temperature. In general, choosing external heating method can improve the distribution of heat. However, there are many potential issues which would cause quality problems – no matter for the product or the hot runner system. A hot runner system is relatively more complex and commonly faced with the challenges of temperature control and the risk of thermal degradation of plastic materials. The heat dissipation from hot runner system to mold base causes high mold temperature during the injection process and increases the cycle time is a common issue. Another issue is Runner flow balance. Achieving a balanced flow pattern is not always an easy task for many mold designers. The different design arrangement for the runner’s diameter and layout will increase difficulties for achieving a flow balance.

Moldex3D Solutions and Benefits

Moldex3D enables designers to simulate the real hot runner systems, including hot nozzle, heating coils, bushing, valve pin, and manifold components. In the hot runner of applied superiority, Moldex3D is able to investigate melt temperature, pressure drop, shear heating effect, and mold-base temperature distribution dynamically in the hot runner systems. These simulating results are very useful in understanding complex hot runner system and finding potential issues in their hot runner designs. As a result, Moldex3D optimizes hot runner system designs and improves product qualities with the less real mold trials, cost, and development time.

Moldex3D Solves Tough Problems

Hot Runner System

  • Challenges
  • Solutions
    • The mechanism is very extensive and mysterious inside various hot runner system. Flow imbalance, dead spot, and non-uniform heating are the significant issues in hot runner system development. More severely, material degradation occurs due to overheating and ultimately affects product quality. As a result, how to maintain melt temperature is the key and it is closely related to geometric design for the entire system and heating control methods.
