Investment Casting
Uses a wax pattern coated with a refractory material. Then, the wax is melted out and the mold is filled with molten metal.
Techniques:
Sand Casting
Uses sand as the main mold material.
Die casting / Permanent Mold / Semi-Permanent Mold
Uses metal molds and high pressure to force the molten metal into a mold.
When selecting metal for a casting project, EQI will work with you to consider characteristics such as strength, hardness, machinability, corrosion resistance, and cost. With these factors in mind, EQI offers a broad range of iron, steel, and aluminum castings across nearly every casting manufacturing process.
Grey Iron
Known for its color, which comes from the graphite flake structure that develops during the solidification process. Grey iron is a popular choice because it’s cost effective.
Ductile Iron (Nodular Iron)
A cast iron with spherical graphite structures in the metal that increase ductility and broaden the range of suitable applications. Stronger than grey iron, ductile iron can be alloyed to boost specific properties such as thermal resistance, strength, and elongation. Due to its high carbon content, ductile iron is a good candidate for various heat treatments to modify the microstructure and material properties further.
Carbon and Alloy Steel
Steels can be tailored for many applications by selecting the appropriate carbon and alloy content. Heat treatment can provide a wide range of strength, ductility, and hardenability. Carbon steel is versatile and economical, making it ideal for general machine and structural applications. It can also be easily welded up to specific levels of carbon equivalence.
Stainless Steel
A ferrous alloy that is highly resistant to oxidation and corrosion due to added chromium that forms a protective oxide layer. There are over sixty different grades of stainless steel, and unique compositions are regularly added to the spectrum.
Nickel-Based Alloys
These alloys are often deployed in extreme working environments. The nickel matrix and alloying additions perform exceptionally in high-temperature and corrosive applications, often in the thermal processing, chemical, and petroleum industries.
Aluminum Alloys
Aluminum alloys have a desirable strength-to-weight ratio, making them ideal for applications where weight is an issue.
