Frequently Asked Questions
The most commonly used metals for casting include aluminum, steel, cast iron, bronze, and brass. Aluminum is lightweight, corrosion-resistant, and ideal for automotive and aerospace components. Steel is strong and durable, making it suitable for structural and industrial applications. Cast iron is known for its wear resistance and ability to withstand high temperatures. Bronze offers excellent corrosion resistance and is often used in bearings and valves, while brass is both functional and decorative, making it popular for fittings and hardware.
There are four main types of metal casting widely used in manufacturing. Sand casting uses sand molds and is suitable for large and heavy parts. Investment casting, also called lost-wax casting, provides high precision and fine surface finishes, making it ideal for complex components. Die casting involves forcing molten metal into permanent molds under high pressure, which is great for producing consistent, high-volume parts. Centrifugal casting uses spinning molds to distribute molten metal evenly, making it ideal for cylindrical shapes like pipes, tubes, and rings.
Common casting defects include porosity, which are small air pockets trapped inside the metal, and shrinkage cavities caused by uneven cooling and contraction. Cold shuts occur when two streams of molten metal fail to fuse properly, while misruns happen when the mold does not fill completely before the metal solidifies. Hot tears are cracks caused by stress during uneven cooling. Proper mold design, temperature control, and material handling are essential to minimize these defects.
Aluminum is considered the easiest metal to cast. It has a low melting point, flows easily into molds, and solidifies quickly. These properties make it ideal for both small and large components, and it can be used in sand casting, die casting, and investment casting. Its ease of casting, combined with light weight and corrosion resistance, makes it one of the most popular metals in the industry.
PDC (Polycrystalline Diamond Compact) is made by bonding diamond grains to a carbide substrate and is commonly used for drilling and cutting hard materials. PCD (Polycrystalline Diamond) is composed entirely of diamond grains without a substrate and is used for ultra-precision cutting and tooling applications. The main difference is that PDC has a supporting substrate for strength, while PCD is pure diamond, offering superior hardness and precision.
