Turning Machining
Turning machining is cutting metal into shapes. Lathes are used for turning. A lathe spins the metal fast. The tool cuts the metal. Speed can be 1200 RPM. Depth of cut is 0.1 mm. Cutting tools are HSS or carbide. Lathe beds hold everything steady. CNC lathes use computers to guide. G-code tells the CNC lathe what […]
Surface Finish Options for the Aluminum Gravity Die Casting
Finish Type Process Description Advantages Shot Blasted Finish Propelling high-speed steel shots at the surface to remove imperfections and improve surface quality. – High rate of material removal – Uniform surface finish – Prepares surface for further finishing or painting Powder Coated Finish Applying dry powder electrostatically to the surface, then curing it under heat […]
What Are Alloys Made Of?
Alloys are merged materials composed of a primary base element combined with various secondary elements. The base element provides the fundamental structure and typically the solubility medium that disperses the other components uniformly, while the secondary elements are added in specific proportions to adjust and bequeath desirable properties of the final material. The resulting alloy […]

Aluminum Gravity Die Casting vs. Aluminum Sand Casting
Feature Aluminum Gravity Die Casting Aluminum Sand Casting Mold Material Permanent mold made of metal (typically steel or cast iron) Temporary mold made of sand and binder Initial Tooling Cost High (due to the durable metal mold) Low to moderate (sand molds are less expensive to produce) Lead Time Longer (due to the time needed […]
What Is the History of Alloys?
Alloys have been used since as early as 3000 BCE. The first known alloys were brass (Copper and Zinc) and bronze (Copper and Tin). Both of these likely originated from early metallurgical learning, where two ores of different compositions were smelted together. We will never know if the first alloys were the result of brilliance […]
Benefits of Gravity Casting Aluminum
High Precision and Consistency:It is used to make the parts have complex geometry. Besides this, it gives high-dimensional accuracy to gravity-cast aluminum parts. It shows consistency throughout the large production runs. Improved Mechanical Properties: Gravity casting aluminum helps give denser and stronger metal structures. Besides this, it improves the mechanical properties, like tensile strength and hardness […]
What Is an Alloy?
An alloy is a material composed of a metallic base, usually the large majority component, and additional metal or non-metal components that are added as property modifiers. Alloys are manufactured and carefully tuned by experiment to deliver desirable properties that are not present in the primary material. Many alloys are made purely of metals, but […]
What Are the Limitations of Copper?
Copper has a number of limitations, some of which are listed below: Is relatively expensive compared to potential alternative materials such as: aluminum (electrical cabling) or plastics (water piping). Is relatively heavy compared to materials such as aluminum, so for overhead wires, it may not be practical. Oxidizes, particularly at high temperatures, and so has […]
Laser Cutting/Engraving
Laser engraving is another popular casting machining method in metal casting foundries. It uses a high-powered laser beam to cut/engrave materials and engrave marks or etch the surface. Both processes are precise, and computer software allows you to control them. In casting machining, a laser machine cuts through metal. The laser melts, burns, or vaporizes […]
