The core performance and user experience of a coffee machine largely depend on the stability and durability of the steam tube nozzle assembly. As one of the key components of a coffee machine, the steam tube needs to withstand high temperatures, high pressure and frequent use. Any material defect or insufficient craftsmanship may lead to steam leakage, reduced efficiency or even safety hazards. Therefore, choosing a high-quality steam tube nozzle assembly is crucial for ensuring the long-term stable operation of the coffee machine.



1. Material Upgrade, Superior Performance

We use SUS304 and SUS316 food-grade stainless steel materials, which have excellent high-temperature resistance (up to 300℃) and corrosion resistance (passing salt spray tests for over 48 hours), effectively preventing rust and contamination, ensuring safety and hygiene during long-term use. Additionally, we employ precise CNC turning technology to keep the nozzle hole diameter error within 0.02mm, making the steam output more uniform and stable, significantly enhancing milk frothing efficiency, and providing users with a superior coffee-making experience.

2. Fully automated production, consistent quality

From raw material cutting to final product inspection, the entire production process strictly adheres to ISO 9001 standards. We employ a fully automated production line, including CNC precision machining, servo automatic pipe bending, laser welding, polishing and grinding, etc., to ensure the accuracy and consistency of each step. Every product undergoes three pressure tests (10Bar, 15Bar, and 20Bar burst tests) to ensure a service life of over five years and a defect rate of less than 0.3%. This strict quality control system guarantees the high reliability of our products.

3. Brand New Customization, Quick Response

We support in-depth OEM/ODM cooperation and can provide a variety of personalized customization services based on customer needs, including size, thread specification, and surface treatment (mirror finish / brushed finish). With advanced production equipment and a technical team, we can complete sample production within 7 days and achieve bulk delivery within 15-30 days, meeting the urgent order requirements of customers. Whether it's commercial or household coffee machine brands, we can tailor the most suitable steam pipe nozzle assembly solutions for them.


How does our production process ensure product quality?

Precision Manufacturing Process (Process Visualization)

1. Raw Material Selection: All stainless steel steam tubes and components are made from food-grade stainless steel tube and undergo 100% spectral analysis to ensure material purity. Special molds and mandrels are used for stainless steel tube to guarantee smooth inner walls and high-quality outer surfaces.

2. CNC Machining: High-precision CNC machines, tube bending, and fully automatic laser welding equipment are utilized, with an accuracy of ±0.01mm, to ensure a perfect fit for stainless steel steam pipes, steam nozzles, and joints. We have a variety of pipe bending molds ranging from 4mm to 20mm in diameter to meet the needs of different customers.

3. Seamless Welding: Argon arc welding and laser welding techniques are employed, resulting in weld strength higher than that of the base material, with smooth surfaces free of burrs. This not only ensures aesthetic appeal but also durability.

4. Surface Treatment: Through automatic polishing machines, ultrasonic high-temperature cleaning, and electrolytic polishing processes, the inner wall Ra value is reduced to ≤0.4μm, providing a fine and smooth surface that minimizes water scale residue and facilitates cleaning and maintenance.


A strict quality inspection system covers every part. Each batch of products must pass 12 quality control tests, including but not limited to:

- All thread parts are fully inspected with go/no-go gauges;

- Outer dimensions are fully inspected with 3D molds;

- Residue detection to ensure high cleanliness of each product;

- Air tightness test (0.5MPa pressure maintained for 30 minutes without leakage);

- Salt spray test (no rust spots after 48 hours);

- Flow consistency test (error ≤ 3%);

- Provide SGS/ROHS certification reports, meeting international safety standards of Europe, America, Japan, Korea, etc.


Why is it more efficient to cooperate with us for OEM/ODM?

One-stop service, reducing costs

We offer a full production chain service from design drawings to finished product packaging, eliminating the need for customers to conduct secondary processing. Additionally, we provide free 3D drawing adaptation and mold development support to help customers reduce R&D investment and shorten the time to market for their products.
