High-Performance Needle Shutoff Nozzle

Product catalog summary

Technical Description: The HP-Nozzle is a pneumatically or hydraulically controlled needle shut-off nozzle designed for processing thermoplastics, excluding PVC. It features a needle shut-off mechanism with an integrated 2-way actuator, suitable for low viscosity materials such as PA, PPS, PE, POM, and PP.

Advantages: This nozzle reduces cycle time, prevents filamentation, air pockets, and material leakage, and supports applications like physical foaming and hot-runner injection molding. It enhances productivity through controlled melt stream shut-off, shorter cycle times, and increased process reliability.

Integrated Actuator: The actuator is compact with temperature-resistant seals, eliminating installation errors. It operates at pneumatic pressures of 5-10 bar and hydraulic pressures of 40-70 bar, with water cooling to maintain cylinder temperature.

Assembly Alignment: Proper alignment and connection of the actuator with the nozzle are crucial. The actuator requires space on the machine plate, and flexible cylinder supply connections are recommended.

Tip Types: The nozzle offers one-piece and two-piece tips with various lengths and heating options. Longer tips can prevent collisions during mold diving.

Optional Extras: Additional modules include filters, mixers, and Gas Injection Technology (GIT) for improved part quality. Needle monitoring and alternative heating systems are available for process control and space-saving.

Data Sheet: Detailed specifications for different HP nozzle models (HP0, HP1, HP2) are provided, including injection rates, screw diameters, flow channels, and maximum pressures and temperatures.

Customer Information: Customers needing specifications beyond the standard range should contact customer services. Information such as machine type and abrasion protection levels are necessary for customization.

Specifications: Specifications for different machine types (HP0, HP1, HP2) include details on dimensions and components like connecting threads, inlet diameters, and temperature sensors.

Safety Instructions: Emphasizes following safety protocols to prevent injury or damage, including wearing protective gear, avoiding overheating, and ensuring proper use of the nozzle for injection molding only.

Installation Instructions: Provides detailed steps for installing the nozzle, including necessary tools and torque specifications. Highlights the importance of aligning components correctly and ensuring proper temperature equalization.

Operational Notes: Specifies maximum injection rates and temperatures, noise emission levels, and precautions against explosion risks due to gas emissions from plastics.

Initial Operation: Instructions for bringing the nozzle to operating temperature, tightening screws, and ensuring complete polymer melting before use.

Service Instructions: Offers guidance on disassembly and cleaning, recommending specific tools and methods for effective maintenance.

Assembly: Lists parts and tools required for assembly, with torque specifications for different components.

Spare Parts Ordering: Provides instructions for ordering spare parts, including contact information and necessary details for processing requests.
