Introduction
PAM-CAST is a process that combines the accuracy of a precision casting process with the size and quality of a low pressure casting process. This method is suitable for producing magnesium alloy, aluminium alloy or titanium alloys wheels with an accuracy of within 1mm for the center hole and 1mm for the spoke and 5mm for the outside of the wheel. This process can produce complex shapes with smooth surfaces and a high accuracy at a low cost.
Pam-Cast Process
The Pam-Cast process begins with the preparation of a master model. The master model is then laser scanned and all the data is transferred to a digital form. This data is then used to design a custom tool for the casting. A low-pressure chamber is then inserted into the die, followed by the pouring of molten metal. After the metal has cooled, it is removed and the manufacturer makes the finishing touches.
Advantages of Pam-Cast
The Pam-Cast process offers several advantages over traditional low-pressure casting, including:
• High accuracy and surface smoothness. As the tool is custom designed for the production, the accuracy and uniformity of the castings are higher than those produced by traditional low-pressure casting processes.
• Lower tooling cost. Compared to traditional low-pressure casting processes, the tooling costs for PAM-CAST are significantly lower. This is because the tool is custom designed to produce castings, eliminating the need for expensive moulding machinery.
• Faster production cycle. As the tool is custom designed for each wheel, the production cycle is much shorter than with traditional low-pressure casting. This allows for faster production of wheels and improved customer satisfaction.
• Reduced waste. As the tool is custom designed, less metal is wasted compared to traditional low-pressure casting processes. This increases the efficiency of the casting process and helps to reduce overall costs.
Disadvantages of Pam-Cast
The PAM-CAST process also has several disadvantages, including:
• Increased complexity. The process is more complex than traditional low-pressure casting processes and requires specialized expertise and skill.
• Limited material options. The process is limited to the use of magnesium alloy, aluminium alloy, and titanium alloys.
• Lower strength. The castings produced by PAM-CAST have a lower strength than those produced by traditional low-pressure casting processes. This means that the castings may need additional post-processing to ensure adequate strength and durability.
Conclusion
Overall, the PAM-CAST process is an effective and efficient process for producing magnesium alloy, aluminium alloy, and titanium alloys wheels with an accuracy of within 1mm for the center hole and 1mm for the spoke and 5mm for the outside of the wheel. This process offers the benefits of higher accuracy and uniformity, lower tooling cost, faster production cycle, and reduced waste, however, it is limited to the use of only three types of alloys and requires specialized expertise and skill.
