Overview

This technical document provides comprehensive specifications and configuration guidelines for the Series 12 E01 manifold nozzles with screw fit, designed for hot runner injection molding systems. The nozzles feature a 12 mm flow bore diameter and offer multiple interchangeable tip shapes and gating types to suit various plastic materials and processing conditions.

1. Product Classification and Nomenclature

• Series: 12 E01
• Nozzle Size: Flow bore diameter of 12 mm
• Nozzle Style: Manifold nozzle with screw fit
• Version: Basic version with interchangeable screw-in nozzle tips
• Tip Shapes and Gating Types: Includes multiple tip shapes (Y, U, P, K, L) and gating types such as open, open with torpedo, and valve gate.

2. Key Dimensions and Parameters

• Nozzle Length (L): Variable depending on tip shape and length code, ranging approximately from 96 mm to over 600 mm.
• Cut Out Dimensions: Mold plate cut-outs specified for nozzle and connections, including grooves for locking pins to prevent rotation.
• Flow Bore Diameter: Standardized at 12 mm.
• Tip Diameter and Hot Runner Gate Diameter: Varies according to nozzle tip type.

3. Heating and Electrical Specifications

• Externally heated nozzles operating at 230 V AC.
• Heating zones range from 1 to 3, with power ratings between 315 W and 1115 W depending on nozzle length and type.
• Temperature sensing via Fe/CuNi thermocouples compliant with DIN 43710.

4. Applications and Material Compatibility

• Suitable for all common thermoplastics.
• Maximum shot weight per nozzle varies by gating type and material viscosity: up to 1500 g for open gates with low viscosity materials, approximately 500 g for valve gate with low viscosity materials.

5. Nozzle Tip Types and Features

• Open (N): Standard open gate for general applications.
• Open with Torpedo (T): Enhanced flow control with torpedo-shaped tip, suitable for medium to wide process windows.
• Valve Gate (V): Provides precise gating control, recommended for narrow to medium process windows.

6. Design and Installation Considerations

• Locking pin grooves and bores secure the nozzle against rotation.
• Cooling is required around the nozzle tip and on the opposite side to maintain optimal processing temperatures.
• The nozzle tip front must always be positioned against the plastic to ensure proper gating.
• General tolerances and surface finishes comply with DIN ISO 2768-mK standards.

7. Configuration and Selection

• Nozzle length codes correspond to specific length ranges or exact lengths depending on the series.
• Heating zone power ratings vary with nozzle length and configuration.
• Users configure nozzles by selecting series, type, length code, and tip shape based on application requirements.

8. Additional Notes and Recommendations

• Illustrations are schematic and not to scale.
• For detailed design and application guidance, refer to the Synventive Hot Runner Guide.
• Consult Synventive for specific application requirements and confirmation of nozzle configuration.
• Ensure compliance with DIN ISO 2768-mK tolerances for mold plate cut-outs and nozzle installation.
• Verify nozzle tip shape and gating type according to the material’s process window.

9. Technical Specifications and Tolerances

• Groove and bore dimensions for locking pins and mold plate cut-outs are specified (details referenced but not included).
• General tolerances for length, shape, and position follow DIN ISO 2768-mK standards.
• Critical dimensional parameters include total length (L), sub-lengths (L1, L2), height (H), and angles (G, F) with specified radius and tolerance limits.

10. Heater Zones and Power Ratings

• Heater power ratings per zone range from 315 W to 1115 W, increasing with nozzle length.
• Tables correlate length codes with heater power requirements for precise thermal management.

11. Nozzle Types and Versions

• Multiple nozzle types (C, P, T, A, S, V, W) with specific tip shapes and gating mechanisms.
• Valve gate types (V) include tip shapes L, S, W; open with torpedo types (T) include S, W.
• Versions 01 and 02 indicate suitability for different process windows and installation constraints.

12. Installation and Application Notes

• Nozzle tip front must contact plastic material for proper gating.
• Cooling is mandatory around the nozzle tip and opposite side.
• Manifold nozzles use screw fit and gating types vary by application.
• Nomenclature differences exist between older and newer nozzle series due to revisions.

13. Summary of Key Tables

• Tables provide length ranges with corresponding heater power per zone.
• Angular parameters and dimensional tolerances are tabulated for precise specification.
• Cooling and heating power requirements increase with nozzle length.
