Small-pitch nozzles go into tight corners

The MIM Dura Atto cartridge heater nozzle turns the melt channel into an integral heater with an optimised axial profile.

At last year's K2001 international trade fair for rubber and plastics, Mold-Masters introduced a new line of small-pitch nozzles that are ideal for moulding in space-constrained applications and for small parts. The MIM Dura Atto cartridge heater nozzle turns the melt channel into an integral heater with an optimised axial profile. As the nozzle-body diameter is under 9mm and has minimal gate vestige, the nozzles suit small, aesthetically sensitive, or specialised products with core diameters greater than 16mm, such as lipstick caps, medical products and container caps.

HansHagelsteid, Technical Director for Mold-Masters Europe, said: 'Precision design and manufacturing, plus years of hot runner experience combine to make a small, highly accurate, and durable unit that is perfect for 'tight spots'.

It really goes where no nozzle has gone before.' The MIM Dura Atto nozzles come in two distinct flange designs.

The 10mm centre-to-centre pitch nozzle is suited for tight gating locations.

The 15mm nozzle is well suited for internal gating of small components and for applications that require high-rate cooling channels, complex inserts or mechanical components.

Because the heater, tip and melt channel are integral, the new nozzle provides better thermal control and needs less maintenance than conventional, multi-piece heater/channel assemblies with screwed-on lips.

The MIM Dura Atto family is the smallest in the Mold-Masters nozzle range and provides ideal heat control at the gate for shot sizes ranging from under 1g to 30g (0.04oz to 1.1oz).
