MIM
This component is a stainless steel fluid nozzle rod/dual‑port connector assembly manufactured via MIM (Metal Injection Molding). It features an integral one‑piece design that integrates a long‑rod flow channel, a mounting flange, and dual‑end interfaces into a single unit. With high precision, exceptional strength, and superior wear and corrosion resistance, it is primarily used in compact fluid systems and household appliances as a medium‑transport nozzle, a分流 (diverting) connector, or a mounting/fixing element, enabling fluid conveyance, spraying, and secure installation and positioning.

I. Basic Product Information
- Product Name : MIM stainless steel fluid spray bar / double‑port fitting assembly
- Manufacturing process Metal Injection Molding (MIM)
- Material : Stainless steel (customizable alloy steel and other alloy materials)
- Core Use : Used as media‑carrying spray bars, distribution fittings, or mounting fasteners within equipment in fluid systems, these components are employed in home appliance control systems and small industrial fluid‑handling devices to enable fluid conveyance, spraying, and secure installation and positioning.
II. Structure and Process Details
- Appearance and Structural Features
- The device features an integrally molded rod‑shaped structure, with a long central flow channel and fluid ports of different specifications at both ends, enabling bidirectional fluid passage or one‑end injection with the other end connected. The inner wall of the flow channel is smooth and free of burrs, minimizing flow resistance.
- The central section is equipped with a mounting flange, which features multiple mounting holes on its surface. It can be directly fastened to the equipment body using screws, providing axial positioning and secure fixation. Additionally, the flange is marked with an identification number to facilitate assembly and traceability.
- The stem and flange transition is smooth, with no sharp corners or stress concentration points, enabling it to withstand fluid pressure and vibration during equipment operation and resisting deformation and fracture over long-term use.
- MIM Process Advantages Are Evident
- One‑step forming of complex structures: Multi‑feature components such as long runner channels, mounting flanges, and mounting holes require no secondary machining; they are directly molded, achieving dimensional accuracy within ±0.05 mm, with high part‑to‑part fit and eliminating the need for additional trimming or fitting.
- Outstanding material performance: The stainless steel, after sintering, exhibits high density with no porosity or shrinkage defects. Following heat treatment, it achieves a uniform hardness distribution, combining the pressure resistance of the stem with the impact resistance of the flange, thereby meeting the operating pressure requirements of fluid systems.
- Strong surface‑condition adaptability: The matte‑finish surface minimizes fluid adhesion while enhancing corrosion resistance, and can be further treated—such as polishing or nickel plating—to suit humid or food‑contact environments.
- Cost and Efficiency Advantages: Near-net-shape manufacturing significantly reduces subsequent machining, achieves high material utilization, and is well-suited for mass production, thereby effectively lowering the per-unit cost.
- Performance Features
- Stable fluid transmission: The integrally molded structure features seamless construction, ensuring excellent flow‑path sealing and the ability to withstand moderate media pressure, thereby minimizing leakage and deformation over long-term use.
- Precise installation and positioning: The flange mounting holes feature high positional accuracy, ensuring uniform clearance when mating with the equipment body. After assembly, there is no wobbling or misalignment, thereby guaranteeing stable fluid flow.
- Excellent corrosion resistance: The stainless steel construction is compatible with a wide range of fluid media—including water, compressed air, and mildly corrosive substances—and remains resistant to rust and oxidation over long-term use, resulting in low maintenance costs.
- Wide customization and adaptability: Parameters such as flow channel diameter, interface specifications, flange dimensions, and mounting hole locations can be tailored to meet customer requirements, ensuring compatibility with the fluid‑handling and installation needs of various equipment.
III. Application Scenarios
It is widely used in applications such as fluid spray rods for home appliance control systems,分流 (diversion) fittings for small industrial fluid‑handling equipment, and media‑transfer components for precision instruments, making it particularly well suited to fluid‑control fields that demand high precision in part flow channels, pressure resistance, corrosion resistance, and batch‑to‑batch consistency.
