Single nozzle | 4519-S Single Version Single nozzle smartFILL - ring gate 4519-S Single version Ring gate DRT3W3 / DRT3W3K / RT3W3 Characteristics • Single nozzle with melt transfer from the injection nozzle directly to the single nozzle support • Nozzle for direct gating or gating through cold runner • Ring gate nozzle with torpedo • Changeable heater with integrated thermocouple • Easy to service Heating Single nozzle support Single nozzle support Nozzle body Melt channel Application For all common thermoplastics with or without fillers. Shot weight / nozzle [g]: • Up to max. 30g, easy flowing thermoplastics Technical data • Externally heated 230 VAC (provide grounding) • Nozzle shaft heating 120-150W + single nozzle support 460W • Connecting cables are temperature resistant up to 200°C. Thermocouple type J, Fe-CuNi, DIN EN 43722 • Cable length nozzle shaft heating 2000 mm • Cable length single nozzle support 1500 mm • Maximum injection pressure: 1800 bar • Contact force of the machine nozzle min. 16 kN 1 Nozzle with single nozzle support The nozzle is ‘inserted’ into the cavity plate and fixed by the clamping plate and/or the locating ring. The injection nozzle ‘moves’ directly on the single nozzle support: • Quick & easy installation of the single nozzle • Cost-effective solution 2 Streamlined melt channel Streamlined, circular cross-sections of the melt channel and a high-quality surface allow the gentle processing of all thermoplastics and offer the following advantages: • No dead spots, optimal melt exchange • Low shear stress of the melt • Good colour changing qualities • Processing of critical materials possible Heating Nozzle shaft The innovative heating technology offers you the following advantages: • Very long service life • Optimal heat transfer • The differentiated power distribution results in a homogeneous temperature profile over the complete nozzle length • The heating can be changed easily and quickly using the intelligent clip lock 4 Different gate types The gate types are available in different versions, resulting in the following advantages: • Simple and flexible adjustment of the nozzles to the most diverse applications and materials • Universal use of the

Single nozzle | 4519-S Single Version Gate types DRT3W3 • Suitable for all thermoplastics with a narrow to medium processing window, including filler material and reinforcing fillers • Highly wear-resistant, interchangeable torpedo and nozzle head • For direct gating or gating through cold runner DRT3W3K • Scope of application like DRT3W3 with calotte at the nozzle head • Highly wear-resistant, interchangeable torpedo and nozzle head • For direct gating • Sprue scrap remains recessed in the calotte • EK-dimension = nozzle code -0.5 RT3W3 • Suitable for all thermoplastics with a narrow to...

Single nozzle | 4519-S Single Version Heating Nozzle code [mm] Control points Single nozzle adapter heater Description HB402601 Important notes • The mould must be grounded. If the nozzle is operated outside the mould, then the nozzle must be grounded. • The connecting cables of the nozzles are temperature resistant up to max. 200°C. • General tolerance according to DIN ISO 2768-mK • Surfaces: ( ) • Provide temperature regulation: - around the nozzle tip - opposite the gating point • Nozzle front surface must touch the plastic. • E dimension = mould dimension. • EK dimension = mould...
