Small parts

Many plastics suffer thermal damage if they spend too long in the molten state. Therefore, this stage should be kept as short as possible. For small shot weights, we adapt the flow channel diameter accordingly to reduce the volume of melt in the manifold. We offer the following hot runner systems for small parts:
  • Slim nozzles with small melt channel diameters of 3.5 mm
  • Compact hot runner systems with close nozzle spacing >22 mm
  • Needle valve systems with a plate drive for close cavity spacing
Using simulation software, our plastics technicians are able to find the best balance between dwell time, pressure loss and shear forces for your application.
