TZM Nozzle Tip

The TZM Nozzle Tip is a nozzle tip made of titanium-zirconium-molybdenum (TZM) alloy. It is commonly used in injection molding equipment.TZM alloy is a high-performance refractory metal alloy. It has excellent high-temperature strength, creep resistance, and corrosion resistance. This nozzle tip is often used in hot runner systems. It helps inject molten plastic material precisely into the mold.

The TZM nozzle tip is changeable according to the desired shape. Meanwhile, the other end of the nozzle is fitted with a screw and can be fitted with a tube with other materials.TZM is a kind of material of molybdenum, with rare titanium and zirconium, which can increase its properties of machineability and life-time if used in a hot runner system.

Titanium zirconium molybdenum hot runner is a new structure that frequently heats the runner and channel of the traditional mold, so that the runner does not need to be removed during each forming process. TZM hot runners are mainly classified into open and needle valve types. The classification of its nozzle tip is mainly divided into: needle valve nozzle tip and special nozzle tip.

High temperature resistance
• The melting point of the substrate is 2620 °C, and the recrystallization temperature is ≈300 °C higher than that of pure molybdenum. It can be used for a long time at more than 1000 °C.
• The strength retention rate under hot runner conditions (≈450 °C) is > 60%, which is much better than ordinary hot working steel.
High strength
• Room temperature tensile strength is 785–1130 MPa, yield strength is 635–1000 MPa; at 1000 °C, it still has a strength of more than 400 MPa.
• Suitable for high wear systems such as glass fiber reinforced plastics to reduce the risk of plastic deformation and cracking of the nozzle tip.
Corrosion and oxidation resistance
• It has good chemical stability to molten aluminum, zinc, glass materials, etc.; after SHN surface hardening, a 30–50 µm diffusion-strengthened layer is generated, and the corrosion and wear resistance are further improved by 3–5 times, and the coating adhesion is better than traditional PVD/CVD.
Strong structural adaptability
• Open type/needle valve type/threaded screw-in type/quick-change type can be manufactured, and the full range of thread interfaces, such as M6-M16 and British UNF, is available.
• Precision machining can ensure the coaxiality of the nozzle tip ≤ 0.01 mm, meeting the requirements of high-gloss plastic parts.
Easy to maintain and repair
• High hardness but controllable brittleness, can be disassembled and assembled with a standard socket wrench; after wear, it can be refurbished by grinding or laser cladding TZM coating, reducing the overall cost by 40-50%.

Injection Molding:
The TZM Nozzle Tip is widely used in injection molding, especially for high-precision plastic products. It ensures smooth plastic flow, reduces melt decomposition and burning risks, and improves product quality.

Aerospace Industry:
In aerospace, the TZM Nozzle Tip helps produce high-performance plastic parts like engine components and wing structures. Its heat resistance and corrosion resistance meet the strict material requirements of this industry.

Automotive Manufacturing:
In car production, the TZM Nozzle Tip is used for interior parts, engine components, and body structures. It boosts efficiency, cuts costs, and ensures part quality and performance.

Electronics Industry:
In electronics, the TZM Nozzle Tip makes device casings and circuit board supports. Its good heat conduction and strength help keep electronic devices running stably.

Pre-installation inspection
– Make sure the nozzle tip is free of bumps and the thread is intact.
– Use a dust-free cloth dipped in alcohol to clean the thread and flow channel to prevent iron filings from entering the system.
Installation torque
– 8–15 N·m (M8–M12 thread) is recommended. Too large a torque may cause TZM to crack.
Operation parameters
– Plastic melt temperature ≤ 450 °C;
– When the glass fiber content is > 30%, it is recommended to use SHN hardened or PVD coated nozzles to extend the life by 2–3 times.
Daily maintenance
– Check the wear of the nozzle tip every 500k productions or 30 days of shutdown;
– Replace it in time when the wear is > 0.1 mm or drawing occurs;
– Use a special socket wrench when disassembling to avoid breakage caused by lateral force.

Repair and renovation
– Minor wear: regrind the flow channel and end face.
– Severe wear: laser clad TZM coating and then fine-process, the cost is 40–50% lower than that of new parts.
