Hand Molding Process

The hand molding process is a traditional method in green sand casting that relies on skilled craftsmanship to produce high-quality castings. This process involves several steps:

• Preparation: The molding sand, composed of silica sand, clay, and water, is mixed to achieve the optimal consistency, with the clay acting as a binder for strength and flexibility.
• Pattern Creation: A pattern, typically made from metal or wood, is used to create the mold cavity. Skilled artisans carefully pack the sand around the pattern, ensuring detailed reproduction of the desired shape.
• Mold Assembly: The sand is compacted by hand or with tools, ensuring it holds the shape and captures intricate details. After packing, the pattern is removed, leaving a cavity ready for pouring.
• Pouring and Finishing: Molten metal is poured into the mold cavity, solidifying to form the casting. Additional finishing processes may be applied to meet specific requirements.

The hand molding process is particularly effective for low-volume production runs or unique components, offering flexibility and high-quality results.

Cold Core Machines

Our facility includes two cold core machines, which are essential for producing high-quality cores in the casting process. The cold core method involves the following:

• Core Production: Cold core machines use a mixture of sand and resin to create cores that are strong and precise. This method allows for intricate designs that are vital for complex castings.
• Core Weight Capacity: Our cold core machines can produce cores weighing up to 25 kg, making them suitable for a variety of casting applications.
• Efficiency: The machines automate core production, enhancing speed and consistency while reducing manual labor.
• Precision: Cold cores offer excellent dimensional accuracy and surface finish, which is crucial for ensuring the quality of the final cast products.

By utilizing cold core machines, we can provide durable and accurate cores that enhance the overall quality of our castings.

Hot Core Machines

We also operate two hot core machines, which utilize heat to cure sand and resin mixtures, producing high-quality cores through the following process:

• Curing Process: In hot core machines, the sand and resin mixture is heated, causing the resin to cure and harden quickly. This results in cores that are robust and ready for use in the casting process.
• Core Weight Capacity: Our hot core machines can handle core weights up to 50 kg, making them ideal for larger and more complex castings.
• Enhanced Strength: Hot cores provide greater strength and thermal resistance, making them suitable for high-temperature applications and complex geometries.
• Automation: Similar to cold core machines, hot core machines streamline core production, improving efficiency and consistency while reducing labor costs.

The combination of cold and hot core machines in our facility allows us to meet diverse casting needs with precision and reliability.
