Stainless steel mechanical parts

Product Overview: Stainless Steel Mechanical Parts

Our stainless steel mechanical parts are precision-cast components tailored for industrial machinery, including but not limited to gears, shafts, valves, flanges, brackets, and connectors. Crafted from high-quality stainless steel materials, these parts feature precise dimensional accuracy, excellent mechanical properties, and strong adaptability to harsh working environments (such as high temperature, humidity, and corrosive media). They are widely applied in automotive, aerospace, marine, chemical, and food processing industries, effectively ensuring the stable and efficient operation of machinery. Meanwhile, we also provide cast iron mechanical parts (gray cast iron, ductile iron) to meet diverse material requirements of different industrial scenarios.

Production Processes & Workflow

We adopt a standardized and visualized production process to guarantee the quality of each stainless steel mechanical part. The core production process includes:

1. Technical Communication & Design Optimization: Our professional engineers conduct in-depth communication with customers to clarify requirements (dimensions, tolerance, working conditions, performance indicators). Using CAD/CAM/CAE software, we perform 3D modeling and process simulation to optimize product structure, improve casting feasibility, and reduce production costs.

2. Raw Material Selection & Inspection: Strictly select high-quality stainless steel materials (304, 316, 316L, 2205 duplex stainless steel) from authorized suppliers. Conduct comprehensive raw material testing, including chemical composition analysis (using光谱仪) and mechanical property detection (tensile test, hardness test), to ensure material compliance with international standards.

3. Mold Making: For precision stainless steel mechanical parts, we mainly adopt investment casting (lost wax casting) to achieve high dimensional accuracy and fine surface finish. For large-size parts, resin sand mold casting is used. Mold production is completed by CNC machining centers to ensure mold precision and repeatability.

4. Precision Casting: Implement vacuum investment casting for stainless steel to avoid oxidation and porosity defects. The casting process is monitored by intelligent temperature control systems to ensure stable molten metal flow and uniform solidification. For cast iron parts, we adopt advanced sand casting technology with strict sand treatment to ensure casting compactness.

5. Post-Casting Processing: After casting, parts undergo shell removal, sand cleaning, and gate cutting. Then, precision machining is performed using CNC lathes, milling machines, and grinding machines to meet final dimensional tolerance requirements. Heat treatment (quenching, tempering, annealing) is optional to adjust mechanical properties according to customer needs.

6. Surface Treatment: Provide diversified surface treatment options, including polishing (Ra≤0.8μm), passivation, shot blasting (SA2.5 standard), electroplating, and anti-corrosion painting. These treatments enhance corrosion resistance, wear resistance, and appearance quality of the parts.

7. Full-Process Quality Inspection: Implement strict quality control at every stage. Key inspections include dimensional inspection (using Coordinate Measuring Machine, CMM), surface defect detection (ultrasonic testing, X-ray testing), and mechanical property testing. Only products passing all inspections are delivered.

In addition to the above core processes, we also master die casting and centrifugal casting technologies, which can be flexibly applied to different material and structural requirements of mechanical parts.

Customer Case: Custom Stainless Steel Mechanical Parts for a German Automotive Parts Manufacturer

A leading German automotive parts manufacturer approached us to customize stainless steel gear shafts and brackets for their new energy vehicle transmission system. Their core requirements included: 316L stainless steel material, machining precision of ±0.03mm for key dimensions, high wear resistance, and a delivery cycle of 20 working days. Our technical team first optimized the product structure based on their drawings to reduce weight by 3% while ensuring strength. During production, we provided weekly progress updates and raw material test reports. We adopted vacuum investment casting and precision CNC machining to meet their strict precision requirements, and performed passivation treatment to enhance corrosion resistance. Finally, we delivered 800 sets of products 1 day in advance, which all passed their strict incoming inspection (including dimensional testing and fatigue test). Up to now, we have maintained a long-term cooperative relationship, with an annual order volume of 2,500+ sets, and have successively customized 4 types of stainless steel mechanical parts for their new energy vehicle product line.
