Ductile Cast Iron Parts

Ductile Cast Iron Parts, also known as ductile iron, ductile iron, ductile iron, ductile iron and SG iron, is a type of cast iron invented by Keith Millis in 1943. Although most Valve cast iron Parts are brittle, they are more resistant to impact and fatigue due to their ductile inclusions. Most of the Valve Ductile Iron Casting Parts produced each year are in the form of ductile iron pipes for water supply and sewer lines, but there are also many ductile iron casting applications in multiple market segments. It competes with polymer materials such as PVC, HDPE, LDPE and polypropylene, all of which are much lighter than steel or ductile iron; Being more flexible, they require protection from physical damage..

Maple’s Service for Valve

Maple machinery serves the Valve industry's steel casting demand market. The foundry sees an opportunity to expand its market share in medium and highly complex Valve Ductile Iron Casting Parts, offering differentiated solutions that make its knowledge of cutting-edge processes and tools available to customers to make new casting projects viable. The internal sales team is mainly responsible for making sales plans according to customer needs and monitoring the progress of orders

Supporting Service for Valve

◉ As mentioned above, in order to work in adverse conditions, the performance of the Valve 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.
