Marine Accessories
Custom Aluminum Casting & Machining Service — From Your Drawing to Finished Parts
This Marine Accessory is a high-durability component designed for marine mounting brackets. It is manufactured by our in-house Gravity Casting (Permanent Mold Casting) + CNC precision machining process. The use of A356 aluminum alloy with T6 heat treatment provides an excellent balance of high strength, superior corrosion resistance in saltwater environments, and lightweight performance. The gravity casting process ensures excellent internal soundness, dense grain structure, and consistent mechanical properties — all critical for marine components that must withstand prolonged exposure to salt spray, resist galvanic corrosion, and maintain structural integrity under dynamic wave loads and constant vibration.
Our one-stop approach — covering mold design, gravity casting, heat treatment, CNC machining, surface treatment (with marine-grade anti-corrosion coating), and engineered packing — delivers a ready-to-install marine component that meets stringent corrosion resistance standards and performs reliably in harsh saltwater environments.

Our Advantages
Technical Advantages
1
Pattern workshop, gravity casting (permanent mold) workshop, CNC machining workshop, heat treatment, surface treatment, and inspection laboratory — all processes are centralized within the same facility. No outsourcing involved. This allows us to maintain full control over both lead time and product quality.
2
Before you commit to tooling production, we provide a detailed DFM report highlighting solidification analysis, riser placement, mold filling behavior, and machining optimization recommendations. We identify potential shrinkage risks and wall thickness issues early, helping you optimize part design for the gravity casting process.
3
We specialize in complex internal cores, thin-to-thick wall transitions, and components requiring high airtightness and pressure tightness. In-house X-ray inspection and leak testing capabilities ensure product integrity and reliability. Our gravity die casting process delivers denser grain structure and superior mechanical properties compared to sand casting — ideal for structurally loaded and fluid-handling components.
