Suzhou Krosino Mechatronic Technology Co., Ltd. delivers high-precision CNC machining solutions for the global coffee culture industry. From professional-grade portafilter handles to complex internal boiler fittings and nozzle components, we utilize our 1,800㎡ manufacturing facility to provide food-grade stainless steel parts that meet the aesthetic and functional requirements of coffee equipment manufacturers in Europe, America, and South America.
In the coffee industry, component reliability and material safety are paramount. Our machining processes for stainless steel are optimized to ensure durability, precision, and adherence to food safety standards, supporting the seamless operation of both commercial and domestic espresso machines.
We specialize in machining high-grade corrosion-resistant stainless steel (e.g., 304, 316). We ensure that all raw materials are sourced from reputable suppliers to meet strict food-contact safety standards, guaranteeing that components like brew group interfaces and steam wands remain hygienic and durable.
Our team of 30-50 skilled engineers and CNC technicians manages complex geometries—such as high-pressure seals and precision flow channels—with advanced CNC turning and milling. We combine technical skill with our robust supply chain to support the quality demands of the international coffee equipment market.
| Processing Requirement | Machining Specification |
|---|---|
| Dimensional Tolerance | CNC turning and milling ensure critical dimensions (e.g., valve fittings, threaded couplings) are held within ±0.01mm to ±0.05mm for leak-free performance. |
| Surface Integrity | We employ specialized polishing and electropolishing techniques to achieve low surface roughness, preventing coffee oil buildup and ensuring ease of cleaning. |
| Corrosion Management | Machined stainless steel components are passivated to enhance natural corrosion resistance, extending the life of parts exposed to hot, acidic brewing environments. |
Q1: How do you ensure the pressure sealing integrity of your stainless steel fittings?
We utilize CNC turning with rigorous thread-form control and internal surface finish optimization. These steps ensure that fittings and seals mate perfectly, preventing pressure leaks even under the high-temperature and high-pressure conditions of professional espresso extraction.
Q2: What is Krosino's approach to achieving the high-end finish required for visible coffee machine parts?
For exposed components like steam knobs or portafilter handles, we apply multi-stage mechanical polishing followed by electropolishing. This process removes micro-burrs and ensures a uniform, mirror-like finish that meets the aesthetic premium standards of coffee equipment brands.
Q3: Can Krosino handle unique or custom designs for new coffee machine models?
Yes, our CNC manufacturing cells are highly flexible. We work closely with client engineering teams to review CAD models, providing prototyping support to refine design features such as ergonomics or flow geometry before ramping up to larger series production.
