Marine Grey Iron Casting Parts

Gray cast iron is characterized by uneven graphite sheet orientation, large material brittleness and poor ductility. It is widely used in Marine Grey Iron Casting Parts of engine block, brake disc, brake drum and housing. Grey cast iron has excellent workability, excellent wear resistance and damping properties.

Maple’s Service for Mining Industry

Maple machinery has been designing and producing grey cast iron parts for short, medium and long production runs. Since its inception, Maple machinery has pursued a vertically integrated policy, focusing on mastering the underlying technologies that make up its core business. Based on this principle of industrial autonomy, the foundry is ultra-modern and accommodates large industrial facilities that are constantly evolving to guarantee its continuous development. The foundry specialises in sheet Grey cast Iron and currently has a production capacity of 19,000 tonnes with its expertise and trade expertise in material and/or machined Parts for Marine Grey Iron Casting Parts..

Supporting Service for Mining Components

◉ As mentioned above, in order to work in adverse conditions, the performance of the Civil Marine Grey 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.
