  • Can accommodate larger parts

Disadvantages of hot runner

  • More expensive molds to produce
  • Color cannot by easily changes
  • Higher maintenance costs and potential downtime
  • May not be suited to certain thermally sensitive materials

Advantages of cold runner

  • Comparatively cheaper to produce and maintain
  • Comparatively cheaper to produce and maintain
  • Color changes can be made quickly
  • Fast cycle times if the systems include robotic assist in removing runners

Disadvantages of cold runner

  • Cycle times are slower than hot runner systems
  • Plastic waste from runners (particularly if they cannot be reground and recycled
