Title: OEM Marine-Grade Hinge (316 SS) - For Cabins & Seating

Description:
Our OEM investment casting hinge is manufactured to the highest standards for demanding marine applications. Crafted from 316 Stainless Steel, the premier material for saltwater corrosion resistance, it is designed to withstand constant exposure to moisture, salt spray, and UV radiation.

The investment casting process guarantees exceptional dimensional accuracy, smooth surface finish, and complex geometric integrity, allowing for seamless integration into your cabin door, hatch, or heavy-duty seating designs. This hinge provides robust, reliable performance where failure is not an option.

Key Features & Benefits:

• Superior Corrosion Resistance: Made from 316 Stainless Steel (with Molybdenum), offering maximum protection against pitting and crevice corrosion in chloride-rich marine environments.

• Precision Engineering: Utilizing the investment casting process for excellent detail reproduction, tight tolerances, and minimal post-casting machining, ensuring a perfect fit for OEM applications.

• Exceptional Strength & Durability: The casting process creates a high-integrity component with excellent mechanical properties, capable of supporting heavy loads and resisting impact.

• Low Maintenance & Long Service Life: Designed to perform reliably for years, reducing maintenance needs and total cost of ownership.

• OEM Customization: Available in custom sizes, pin designs, and configurations to meet specific engineering requirements and aesthetic designs for cabinetry and seating.

• Smooth Finish: The casting process allows for a clean surface ready for installation or a final polished finish to match marine interior standards.

Typical Applications

• Marine Cabin Doors & Hatches

• Heavy-Duty Helm Seats & Passenger Seating

• Storage Locker Doors

• Furniture and Galley Components

• Access Panels and Inspection Plates

Material: 316 / 316L Stainless Steel

Process: Investment Casting (Lost-Wax Casting)

FAQ

Q1: Why is 316 Stainless Steel the preferred material for these marine hinges?
A: 316 Stainless Steel contains Molybdenum, which significantly enhances its resistance to pitting and crevice corrosion compared to 304 SS. This makes it the international standard for "marine-grade" stainless steel, essential for withstanding harsh saltwater, spray, and humid environments.

Q2: What are the key advantages of the investment casting process for these hinges?
A: Investment casting (or lost-wax casting) offers three major advantages for OEM components:

• Design Freedom: It can produce complex, near-net-shape geometries that are difficult or expensive to achieve with other methods.

• Superior Surface Finish: It delivers a smooth surface right out of the mold, reducing the need for extensive post-processing.

• Dimensional Accuracy: It ensures high precision and consistency for every part in a production run, which is critical for OEMs requiring perfect fit and interchangeability.

Q3: As an OEM, can I customize the hinge to my specific requirements?
A: Absolutely. These hinges are designed for OEM customization. We can work with your technical drawings to modify:

• Dimensions (leaf length, width, thickness)

• Hole patterns (size, position, countersinking)

• Knuckle design and pin type

• Surface finish (e.g., as-cast, polished, bead-blasted)

• Load-bearing specifications

Q4: What kind of quality certifications and testing do you provide?
A: We provide Material Test Certificates (MTC) compliant with EN 10204 3.1. Standard quality checks include 100% dimensional and visual inspection. Upon request, we can perform more advanced Non-Destructive Testing (NDT) such as Dye Penetrant Testing (DPT) to check for surface defects or X-Ray inspection for internal integrity.

Q5: How does the corrosion resistance of an investment cast part compare to a CNC machined part?
A: The inherent corrosion resistance of 316 SS is the same. However, the investment casting process can produce parts with more uniform material structure and smoother surfaces with fewer crevices where corrosion can start. For critical applications, a post-casting passivation process is highly recommended to maximize the corrosion resistance by removing free iron from the surface.

Q6: What is the typical lead time for a custom OEM order?
A: Lead time depends on the order quantity and complexity. For standard designs, it is typically X-X weeks. For new, custom designs requiring tooling and sample approval, the initial lead time will be longer to account for prototyping and validation. We provide detailed project timelines upon receipt of your specifications.

Q7: What is the minimum order quantity (MOQ) for custom hinges?
A: MOQ is influenced by the custom tooling cost required for your specific design. We work with our OEM clients to find economical solutions, whether for low-volume prototype runs or high-volume production. Please contact us with your project details for a precise MOQ.

Q8: What finishing options are available?
A: Common finishes include:

• As-Cast: The standard finish straight from the mold.

• Bead Blasted: A uniform matte, non-glare surface.

• Mechanically Polished: A smooth, bright, aesthetic finish.

• Electropolished: A superior finish that further enhances corrosion resistance and deburrs the component.

• Passivation: A chemical treatment that removes contaminants and strengthens the natural oxide layer.
