types of CNC machining
Our CNC machine galvanized machined connectors are precision-engineered components manufactured using advanced CNC turning, milling, and drilling processes. These connectors are designed for demanding industrial applications where reliability, corrosion resistance, and exacting tolerances are essential. The galvanized finish provides superior protection against rust and environmental factors, making them ideal for both indoor and outdoor use. Whether you need standard threaded connectors, custom-designed fittings, or high-volume production runs, our manufacturing capabilities ensure consistent quality and fast turnaround.

Frequently Asked Questions
What materials are used to produce your galvanized connectors?
-
We primarily manufacture CNC machined connectors from carbon steel (Q235, 45# steel), alloy steel (40Cr, 35CrMo), and stainless steel (304, 316). Carbon steel with galvanized finish offers high cost-effectiveness and is suitable for general industrial applications, while stainless steel provides superior corrosion resistance for marine engineering or chemical equipment.
What is the typical thickness of the galvanized coating?
-
It depends on the galvanizing process you choose. Conventional electro-galvanizing (blue/white or yellow zinc) typically provides a coating thickness of 5 to 12 microns. In contrast, hot-dip galvanizing can achieve a thickness of over 50 microns, making it ideal for long-term outdoor exposure. We can also adjust the coating thickness based on your specific salt spray test requirements.
What thread standards can you machine?
-
We can machine a wide variety of international thread standards, including NPT (American Standard Taper Pipe Thread), BSP (British Standard Pipe Thread, including BSPP and BSPT), Metric threads (M series), and UNF/UNC (Unified National Fine/Coarse). If you require non-standard threads, we can also produce custom parts upon providing drawings or samples.
What are the maximum temperature and pressure these connectors can withstand?
-
Temperature and pressure resistance primarily depend on the base material. For example, carbon steel galvanized connectors perform stably within a range of -20°C to +200°C. Regarding pressure resistance, our precision machining ensures uniform wall thickness. Standard products can typically withstand working pressures up to 3000 PSI, with higher pressure ratings available for custom designs. Specific parameters need to be calculated based on dimensions and wall thickness.
What is your Minimum Order Quantity (MOQ)?
-
For standard CNC galvanized connectors, our MOQ is typically 500-1,000 pieces. However, for custom non-standard parts requiring drawings or for first-time cooperation, we support small trial orders or even sample orders to facilitate your market testing and installation validation.
