Carbide nozzle hot runner injection head

Cemented carbide (tungsten steel) hot runner injection nozzles are extensively employed in the high-temperature injection molding sector. Their superior wear resistance and exceptional high-temperature performance make them indispensable components within hot runner systems. Thanks to the inherent high hardness and resistance to thermal fracture of cemented carbide materials, these nozzles maintain unwavering stability under prolonged high-temperature and high-pressure conditions.

Below are the precision machining standards our company achieves, highlighting the outstanding performance of cemented carbide nozzles:

• Hole Diameter Precision: Achieving tolerances of ±0.003mm to ensure the stable flow of molten material.
• Concentricity: Attaining precision up to 0.002mm to guarantee accurate alignment with other components, thereby minimizing wear and leakage.
• Cylindricality: Maintaining precision up to 0.003mm to ensure the nozzle’s shape accuracy, enhancing sealing efficacy.
• Parallelism: Realizing precision up to 0.002mm to ensure flawless interfacing with other parts.
• Hole Depth Accuracy: Achieving tolerances of ±0.005mm to meet precise control requirements for varying depths.
• Minimum Groove Width: Precise machining down to 0.2mm, suitable for intricate microstructures.
• Surface Roughness: Attaining a Ra of 0.02, providing an ultra-smooth surface to reduce material adhesion and improve flow efficiency.
• Internal Thread Processing: Capable of machining threads as fine as M1.6 to accommodate micro-thread connections.

These high-precision manufacturing capabilities enable cemented carbide hot runner injection nozzles to excel in demanding injection molding processes. They not only elevate product quality and extend the lifespan of equipment but also significantly reduce maintenance costs, making them the ideal choice in the high-temperature injection molding industry.
