(1) The influence of casting structure: a. Casting wall thickness, large shrinkage rate, thin casting wall, small shrinkage rate. b. The free shrinkage rate is large, and the hindered shrinkage rate is small.

Stamping parts design plays a crucial role in the manufacturing industry, particularly in the production of metal components used in various applications, from automotive to electronics. This process involves creating parts through the use of die and punch tools, shaping material into desired forms with precision and efficiency. In this article, we will explore the fundamental aspects of stamping parts design, emphasizing its significance, design considerations, and innovations in the field.

The sand casting process begins with the creation of a pattern, which is a replica of the object to be cast. The pattern is typically made from metal, wood, or plastic and is slightly larger than the finished product to account for shrinkage during the cooling process. Once the pattern is ready, a two-part mold is formed by packing sand mixed with a bonding agent around the pattern. The sand needs to be tightly packed to ensure it can withstand the molten metal's weight and temperature.

Aluminum alloys are highly sought after in various industries due to their lightweight, corrosion-resistant, and strong characteristics. The aluminum billet casting process is a fundamental method employed to produce aluminum billets, which serve as the raw material for various subsequent manufacturing processes, including extrusion, forging, and machining. This article will delve into the steps, methods, and advantages of the aluminum billet casting process.
