Modeling and casting are one of the most commonly used methods in the manufacture of metal parts, especially cast iron parts. Cast iron is widely used in various industries such as automotive, industrial machinery and plumbing due to its proper mechanical properties, low production costs and high casting capability. This article deals with the processing and casting process of cast iron parts.

Modeling is the first and most important step in the casting process to help form a molten metal formation. Models can be made of various materials such as wood, metal, plastic and resin.
Types of models
• One Model: for simple components that do not have a complex shape.
• Multiple Model: for complex components that require easy separation from the template Have.
• Model with muscle: for components with internal cavities or hollow shapes.
• Permanent Model: Made of metal, used for mass production.
Model Making Methods
• Wood or metal machine to build precision models
• 3D printing for complex and high -precision models
• Silicone molding for the production of prototypes
The cast iron casting process
casting is a process in which the molten cast iron is poured into the mold and after the cooling, the final piece is obtained. This method is for the production of complicated, economical and efficient forms.
Steps to cast iron
1. Model: Model is made according to the design of the piece.
2. Used for molding.
3. Moltening cast iron: melted at temperatures of about 1 to 2 degrees Celsius and poured into mold.
4 Cooling and freezing: The cast iron is cooled and the shape is desired.
5. And the piece comes out. Then the levels of the payment are paid and the deficiencies are eliminated.
A variety of cast iron casting methods
• Sand forming: cheap and most common method
• Accurate casting (missing wax): For delicate and accurate pieces
• Pressure casting: To produce precise parts with precision parts Thin walls
• Central casting: Suitable for cylindrical parts and pipes
The advantages of cast iron casting
✔️ Low Production Cost
✔️ Complicated shapes Production Ability
✔️ High Corrosion Resistance

Conclusion
cast iron casting is one of the most important methods of manufacturing industrial parts that can be produced with quality and economical parts by using precise modeling and process control. Choosing the right casting method and using appropriate raw materials has a significant impact on reducing defects and enhancing the quality of components.
