Ductile iron has a minimum tensile strength of 60,000 psi and a minimum yield strength of 40,000 psi. The commonly determined properties of ductile iron are tensile strength, yield strength, and elongation. The Marine industry uses Marine Ductile Iron Casting Parts at a relatively high frequency due to the nominal and consistent influence of spherical graphite, the tensile properties of ductile iron and Brinell hardness have a good correlation..

Maple’s Service for Marine Industry
A large proportion of today's production is produced by the offshore Marine industry. Metal casting is one of the oldest and most common casting processes. The most important Marine Ductile Iron Casting Parts. Maple machinery is a global supply chain management company with cast iron and metal casting partners producing gray ductile iron, gray iron, and lightweight metal parts for aluminum, brass, and alloys. We provide customized solutions based on customer requirements..
Supporting Service for Marine Components
◉ As mentioned above, in order to work in adverse conditions, the performance of the Civil Marine Ductile Iron Casting Parts must be excellent. Therefore, it’s not enough to only produce raw castings or forgings, but also need heat treatment, machining, surface treatment, NDT testing, etc.
◉ Heat treatment: heat treatment is the critical step to improve the mechanical properties of the workpiece. We can formulate the process according to the strength requirements of the parts, and improve the mechanical properties of the parts such as hardness, yield strength, tensile strength and elongation by heat treatment
◉ Machining: we have our own machine shop, and can complete almost all machining requirements with advanced equipment.
◉ Surface treatment: the purpose of surface treatment is to make parts work in adverse environment. Zinc plating can prevent parts from rusting; Nickel plating can enhance the wear resistance and corrosion resistance of parts; Phosphating can prevent parts from corrosion…
◉ Non-destructive testing (NDT): NDT is the last and most important step. Maple will NDT the parts to ensure that there are no surface defects (such as cracks, sand holes, blow holes) and no internal defects (shrinkage and slag) on the delivered parts.

Why Sand Casting
Sand casting is an ancient casting process where the metal parts are molded by pouring metal into a hollow cavity. The mold-based manufacturing process is used to make castings with materials of iron, steel, and Aluminum. Casting-based manufacturing includes several steps and can create a wide range of shapes and sizes for metal products. The process begins with the making of a mold pattern and a gate system with the exact size and shape of the required part. The temperature required depends on the metal as some metals take a long time to heat and melt.
Maple Machinery has continuously upgraded its Sand-casting equipment and refined the casting process. The aim behind this is to use only the advanced casting technology for its Sand-casting operations. Each step follows the customer’s drawings and instructions to deliver precise solutions.
