High Quality melt flow means better cash flow.

The StaMixCo SMN Injection Moulding Mixing Nozzle contains eight (8) very efficient static mixing elements that homogenize the polymer melt during injection.

This homogenization is achieved by the continuous division of the molten polymer and its recombination when processed through the geometric structure of the mixing bars.

Feature and Benefits:

  • Reduced spots, streaks and clouds of colour
  • Reduced colorant usage (up to 40% less) with comparable part colour density
  • Narrower part tolerance
  • Reduced reject rates
  • Less part distortion
  • Less part weight variation
  • Improved part quality when using regrind material and increased use of regrind.
  • Shorter cycle times
  • Improved surface and mechanical properties
  • Blended thermal degradation products (i.e., PET)
  • Improved melt flow, uniform filling of multi-cavity moulds
  • Expanded operating range of older machines

Construction:

The SMN mixing elements are extremely resistant due to their monolithic cast construction where the mixing bars are joined to each other and to the external ring wall via a single molten metal pour.

They are made of heat treated high strength 17-4 PH stainless steel and are virtually indestructible.

Pressure drop through the static mixing elements is low.

Mixing Quality:

The optimum polymer melt quality for injection moulding is reached when at each location inside the polymer melt volume, a uniform distribution of colorant, additives and melt temperature exists. Using the StaMixCo SMN mixing elements, 80% of mixing (CoV = 0.2) is reached after eight elements and 97% (CoV = 0.03) after 16 elements.

Construction:

The SMN mixing elements are made of high strength 17-4 PH heat treated stainless steel. The outside diameter and faces of the mixing elements are machined. The SMN mixing elements are extremely strong due to their monolithic cast construction where the entire mixing element is made via a single molten metal
pour.

This means that the neighbouring mixing bars of the mixing grid are connected to each other and their ends are connected to the ring wall.
