QTi® Copper Titanium Nozzle Tip
for Hot Runner Systems
Copper Titanium Nozzle Tips for Hot Runner Systems provide high wear resistance to abrasive molten plastic polymers coupled with good thermal conductivity which precisely allows controlling molten plastic temperature and fluidity.
Copper Titanium Hot Runner Nozzle Tips
With the advancement in plastic technology, new polymers are synthesized for demanding Industrial and engineering applications. To achieve high quality and desired properties these plastics require an extremely precise processing temperature.
If the temperature of molten plastic entering the mould is at a slightly lower or higher temperature, the produced part may turn out to be defective. If the temperature is lower, the plastic does not flow evenly into the mould or fill all the cavities. A higher temperature polymer flow results in uneven solidification and longer hold-time. Heat transfer in the hot runner nozzle is therefore essential, to precisely maintain the desired temperature.
To keep the plastic at the right temperature, the nozzle is externally heated using heating coils. Only at the very end - at the nozzle tip no further heating aid is used and the heated nozzle itself must transfer the heat to the plastic.
Consequently, the thermal conductivity of the material is crucial.
Why Copper Titanium Hot Runner Nozzle Tip?
Copper Titanium material exhibits good thermal & electrical conductivity, which make it an ideal material for welding & thermal deposition application.
High Temperature Performance
Copper Titanium has highest annealing /softening among all copper alloy used in welding application. It can sustain temperature up to 425 °C without losing its Mechanical properties.
Copper Titanium material offer superior corrosion resistance.
Copper Titanium Nozzle Tips have manufactured have a hardness ranging from 260 to 320 BHN
Copper Titanium material is made from high-quality Copper & Titanium and is 100% free from Beryllium
Copper Titanium is safe and environmental friendly metal.
Comparison of Copper Titanium with other Material
The two materials commonly used to make dies are - Steel Alloys and Copper Beryllium. While steel alloys meet most of the requirements, it has very poor thermal conductivity and therefore presents serious limitations where good thermal conductivity is necessary to produce a good part or optimize productivity. Copper Beryllium has higher thermal conductivity than steel alloys, but is an extremely hazardous alloy, making it unsafe for users and environment. QTi® is therefore an excellent replacement to CuBe and is completely safe. A die made by intelligently using Steel alloys and QTi® can deliver high quality parts, while increasing productivity and lowering costs.
