Applications of Construction Machinery Stamped Parts
-
Brackets & Beam Connectors
Provide heavy-duty load-bearing support in steel and wood-framed buildings.
-
Wall Studs & Joist Hangers
High-precision, standardized metal studs and hangers offer uniform load paths and safety across commercial and residential structures.
-
Chassis & Frame Components
Stamped structural supports are used in the undercarriages and bodies of large vehicles to maximize the strength-to-weight ratio.
-
Panel Fastening Systems
Specialized metal clips, hinges, and industrial clamps allow for quick, secure assembly of facade components and temporary structures.
Common Surface Treatment Processes for Construction Machinery Stamped Parts
Cleaning
Stamped parts often require cleaning to remove grease and oils. For some applications high precision cleaning is required to remove particles and contaminants. This technical cleaning can be done with various methods and solutions including bubbling water baths or vibrating baskets in cleaning solution.
Heat Treating
Heat treatment is often applied to transporting parts through an oven or industrial furnace. The high heat alters the metal’s grain structure to enhance hardness, smoothness, and other characteristics.
Plating
Adding a protective outer layer of metal can be done before or after the stamping process and improves corrosion resistance, conductivity, or other properties. Common plating materials include nickel, copper, tin, zinc, and precious metals. Learn more about plating here.
Deburring, Sanding And Grinding
These methods use abrasives such as sandpaper or a grinding wheel tool to remove burrs or imperfections, smooth rough edges, and prepare the metal for further treatment.
Different Materials for Construction Machinery Stamped Parts
Carbon Alloys
Carbon alloys are beneficial to use when creating machinery stamped parts due to its corrosion resistance and extreme temperature stability. The carbon content in our alloys is below 5% by weight, meaning the steel can achieve a greater weldability and formability but still maintain the strength of steel.
Aluminum
On the other hand, aluminum can be used for parts that don’t require much strength. Due to the lack of density in aluminum, the energy output for machining is fairly low compared to machining other materials. If your machine has weight restrictions, using aluminum parts may prove to be beneficial due to its low density and light weight.
Brass
Along with having great strength and being resistant to corrosion, brass is often used for heavy machinery that is visible to others due to its favorable appearance and color. Brass is also very resistant to rust, making it a favorable material for machines that will be operating near water or in high humidity atmospheres.
Stainless Steel
One of the most widely used metals for machining purposes today is stainless steel. Although it’s very popular, it may be hard to machine due to its intense strength and hardness. However, because of its hardness, it is a great material for heavy machinery that will be used outdoors, as it has a low corrosive property as well.
