· Product Overview
This Precision Machined Black Metal Flange is engineered for reliable connection, fixing, and sealing in industrial machinery, automation equipment, and mechanical assemblies. Manufactured from high-quality alloy steel via advanced CNC machining and surface treatment processes, it delivers exceptional dimensional accuracy, wear resistance, and corrosion protection—ensuring stable performance in critical applications.
· Core Specifications
- Material:
- Alloy Structural Steel (e.g., 45# Steel) / Carbon Steel: Offers high structural strength and machinability, ideal for heavy-duty mechanical scenarios.
- Surface Treatment: Black Oxide (Blackening) Finish – Enhances corrosion resistance, wear resistance, and provides a uniform black aesthetic suitable for industrial environments.
- Process Standards:
- CNC Turning & Milling: Dimensional tolerance controlled within ±0.02mm, ensuring precise thread accuracy, hole alignment, and seamless compatibility with mating components.
- Thread Precision: Engineered to industry thread standards (metric/imperial) for reliable screw connections.
· Application Scenarios
- Industrial Machinery: Used as connection flanges, bearing seats, or fixed adapters in gearboxes, pumps, and machining centers.
- Automation & Robotics: Serves as structural elements in robotic arms, linear motion systems, and assembly equipment for accurate positioning and load-bearing.
- Hydraulic & Pneumatic Systems: Components in valves, cylinders, and fluid control units, designed to withstand pressure and ensure leak-proof performance.
- Mold & Tooling: Accessories for injection molds, stamping dies, and precision fixtures, utilized for component positioning or sealing.
· Production Process Introduction
- Material Preparation: Source certified alloy steel or carbon steel bars, and conduct tests for chemical composition, hardness, and dimensional consistency.
- CNC Machining: Use CNC turning and milling machines to shape the flange, machining the outer diameter, inner thread, mounting holes, and other features with micron-level precision.
- Surface Treatment: Undergo black oxide (blackening) process to form a protective layer, enhancing corrosion resistance and achieving the black finish.
- Quality Inspection: Verify dimensions with calipers and thread gauges, check surface finish uniformity, and ensure thread integrity to meet industry standards.
· Packaging and Shipping Methods
- Packaging: Each flange is individually wrapped in anti-rust film and placed in a sturdy box. Bulk orders are packed in moisture-proof containers with partition layers to prevent scratching and corrosion during transit.
- Shipping: Supports International Express (DHL, FedEx, UPS) for small orders, Air Freight for urgent deliveries, and Sea Freight for large-volume shipments. Tracking information is provided for all orders.
