Product Categories – Quick Change Nozzles
The nozzle tips are available in various lengths, tip radii and thread sizes, and come in the following configurations:
- General Purpose
- Nylon Reverse Taper
- ABS Full Taper
Material & Quality Specifications
- Nozzle tip material: Tool steel 1.2344 hardened to 48–50 HRC.
- Nozzle body material: 1.2312 up to 30% glass fibre (GF).
For higher GF content, the bodies are also made from hardened 1.2344 steel.
| Component | Steel | Hardness / Notes |
| Nozzle tips | 1.2344 (H13) | 48–50 HRC, high resistance to erosion and heat |
| Nozzle bodies ≤ 30% GF | 1.2312 | Tempered |
| Nozzle bodies > 30% GF | 1.2344 | Hardened, increased durability |
Quality control: 100% dimensional inspection and ultrasonic structure check for each batch. 3.1 material certificates (EN 10204) available on request.

FAQ – Frequently Asked Questions
| Question | Short Answer | Details |
| 1. What is the purpose of the nozzle? | Connects barrel and mould. | Maintains melt temperature, minimises pressure drop and dead spots. |
| 2. Difference: open vs. shut-off nozzle? | Open: simple, low cost. Shut-off: needle stops flow. | Ideal for fluid plastics (PA, PBT, PET), prevents stringing. |
| 3. When to use a filter nozzle? | When processing regrind or contaminated material. | Filter insert captures particles, protects hot runners and mould. |
| 4. How to choose orifice diameter? | Usually 1.5–3.5 mm. | Larger parts or high viscosity → larger orifice. |
| 5. How to avoid “cold slug”? | Maintain proper temperature, avoid long machine stops. | Use heater bands, retract screw if needed. |
| 6. Are tips interchangeable between bodies? | Yes, if thread and tip radius match EUROMAP/DIN. | Typical threads: M14×1.5, M18×1.5, M24×1.5. |
| 7. How often to clean and maintain the nozzle? | On every material or colour change. | Purge with ULTRA PLAST cleaning granulate and check seals. |
| 8. When is an extended nozzle required? | When the mould bushing is deeply recessed. | Heat or insulate the extended nozzle. |
| 9. Do you help select the right nozzle? | Yes – free consultation with a process engineer. | Send us your mould drawing and resin details, we’ll recommend the best option! |
Technical Tips
| Tip | Why it matters | Typical values |
| Nozzle contact force | Too low = leakage; too high = bushing deformation. | Small/medium machines: 20–40 kN; large: 50–70 kN |
| Tip radius ↔ bushing radius | Less contact = less heat loss. | EUROMAP standard: R15, R20, R25 mm |
| Tip tightening torque | Prevents leaks and thread damage. | M18: 30–40 N·m; M24: 55–90 N·m |
| Filter pressure monitoring | Detect clogging, avoid damage. | Replace insert at ΔP ≥ 10 MPa |
| Heating extended nozzles | Keeps melt temperature stable near the mould. | Heater band 250–350 °C, sensor near the tip |
| Bushing radius match | Avoid eccentric forces and leaks. | Bushing radius ≈ 1 mm smaller than tip radius |
