The Evolution of China’s Precision Casting Industry

2. Dimensional Accuracy Resin-bonded molds provide excellent dimensional stability, which is vital in industries like aerospace and automotive. The method allows for tighter tolerances, ensuring that the final products meet strict specifications, often eliminating the need for extensive machining post-casting.

A die casting core is a movable part of the die that creates internal features or cavities within a cast part. It serves as a mold section that defines the interior shape of the part being produced. Typically made from steel or other heat-resistant alloys, cores are designed to withstand the extreme temperatures and pressures associated with the die casting process. They are often utilized to create hollow sections, complex geometries, or features that cannot be achieved through standard molding techniques.

The wall thickness affects the manufacturing process’s efficiency. Thinner walls generally allow for faster cooling and solidification times, leading to shorter cycle times in aluminum die casting. A reduced cycle time translates to increased output and improved productivity.

3. Strength and Durability Parts produced through die casting exhibit excellent mechanical properties. The process produces a dense, refined microstructure in metals, resulting in components that are not only strong but also lightweight. This characteristic is particularly important as manufacturers aim to reduce vehicle weight to improve fuel efficiency, especially in the era of electric vehicles.
