hotcast Sprue Nozzle

Product catalog summary

Overview: The document provides technical specifications and advantages of the hotcast Sprue Nozzle models ZD 50/80 and ZD 125, designed for zinc die-casting applications. These nozzles are part of hotset's offerings in industrial heat technology, focusing on improving production efficiency and product quality.

Key Advantages:

Improves cycle time and part quality.
Reduces porosity and eliminates costly sprue cones.
Decreases tool costs and allows for improved mold design options.
Reduces scrap after electro-plating processes.
Provides continuous heating from the goose neck to the mold.
Integrates with 50 t, 80 t, and 125 t die-casting machines.

Performance Improvements:

Up to 40% reduced cycle time.
Up to 30% less shot weight.
Up to 7% more part weight due to higher microstructure density.

Technical Features:

Standard connection voltage: 230 V.
Temperature sensor: Type K (NiCr-Ni), internal.
Max temperature insulation ring: 800 °C short term, 500 °C long term.
Pressure resistance of insulation ring: 330 N/mm².
Heater: Hotspring classic, brass.
Insulation resistance: ≥ 5 MOhm at 500 V DC.
High voltage test: min. 800 V AC.
Leakage current: ≤ 0.5 mA at 253 V AC.
Connection lead: PTFE insulated, CU nickel with stainless steel sleeving.
Max lead temperature: 260 °C.

Options and Compatibility:

Compatible with hotcast Sealed Heater (GMH) and hotrod die-casting cartridge heaters (HHP/G).
Temperature control unit: hotcontrol C448.
Available as a set with control unit and other components.

Installation Instructions:

Observe minimum inner bending radius of 4 mm.
Avoid bending unheated areas back and forth.
Do not bend the heater within 5 mm from the connection head.
Ensure permanent contact with the hotcast die-casting nozzle heater during the cycle.

Dimensions and Tolerances: Detailed dimensions for ZD 50/80 and ZD 125 are provided, with general tolerances according to ISO 2768-m.
