Types of Sand Moulding Machines
1. Vertical Moulding Machines
Vertical sand moulding machines, like the DISAMATIC® from DISA Group, are designed for high-speed production. They offer a rigid construction that ensures quality and efficiency. Ideal for customers transitioning from manual processes, these machines can produce large castings while maintaining high yields and minimal downtime. The vertical design allows for enhanced automation, making it a popular choice in modern foundries.
2. Flaskless Moulding Machines
Flaskless moulding machines, such as those offered by Sinto America, eliminate the need for traditional flasks, streamlining the moulding process. These machines are versatile, suitable for various applications including small and medium-sized castings. Compact models are available, allowing for adaptability to specific production needs without compromising quality. With high moulding rates, they facilitate a faster production cycle.
3. Horizontal Moulding Machines
Horizontal moulding machines are ideal for producing intricate castings like valves and auto parts. The ATHI Automatic Flaskless Green Sand Moulding Machine exemplifies this type, providing complete automation in a horizontal configuration. This design is particularly suitable for small to medium-sized castings, ensuring precision and efficiency. The ability to handle diverse materials, including ductile iron and non-ferrous metals, enhances its appeal.
4. Automatic Moulding Machines
Automatic sand moulding machines, such as those from Juneng Machinery, integrate multiple functionalities including moulding, closing, and unboxing. These machines are perfect for manufacturers aiming to boost productivity while maintaining quality. With a range of models available, they can accommodate various casting requirements, ensuring flexibility in production.
5. Jolt Squeeze Moulding Machines
Jolt squeeze moulding machines are more traditional, often used for general-purpose casting. They allow for manual or semi-automated processes, which may reduce initial investment costs but can lead to lower output compared to fully automated systems. While they may lack the speed of modern machines, they remain relevant for specific applications within smaller foundries.
