An OEM (Original Equipment Manufacturer) cast iron mooring sinker is a specialized counterweight, often used in the marine industry, that is manufactured by a supplier to meet the specifications of another company (the OEM). These sinkers, made of cast iron, are used to anchor or secure vessels or other marine structures. 

Here's a more detailed breakdown:

Counterweight:The primary function of a mooring sinker is to provide a stable and secure anchor point for vessels or structures, effectively counteracting buoyancy and wave action. 

Cast Iron Material:Cast iron is chosen for its density and durability, making it ideal for providing a concentrated weight in a relatively compact size, according to Sinostar MACH. 

OEM Manufacturing:OEM means the sinker is manufactured by one company according to the specific requirements (design, dimensions, weight) of another company (the OEM). This allows the OEM to tailor the sinker to its specific mooring needs. 

These sinkers are commonly used in Marine:

Mooring Buoys: To secure buoys used for navigation or marking. 

Offshore Platforms: To anchor offshore platforms. 

Ship Moorings: As a weight to help moor ships. 

Boatyards: To secure vessels in boatyards. 

Advantages of Cast Iron:

Consistent Weight: Cast iron maintains its weight underwater, unlike concrete, which can erode over time. 

Durable and Wear-Resistant: Cast iron is resistant to wear and corrosion, providing a long lifespan. 

Compact Size: Cast iron's high density allows for achieving the required weight with a smaller footprint compared to materials like concrete. 

At Sinostar MACH, the cast iron counterweight is our primary product. We are able to produce OEM cast-metal counterweight for different purposes such as crane, forklift, kettlebell, marine buoy, elevator, etc.

All of our casting weight products are manufactured meeting international standards, applying modern technologies, and maintaining competitive prices.
