What is metal stamping?
We have already talked about two widely-used metals,stainless steel and aluminum.This time,we are going to introduce you a manufacturing process well known to people.From the car you drive to the smartphone in your pocket, countless everyday items rely on this manufacturing process,which is called metal stamping.From the name,metal stamping seems like a mean to press metal.Actually,it is about this and more than this!Metal stamping is prized for its speed, precision, and ability to produce complex geometries with minimal waste.But what is metal stamping exactly, and why is it so vital to modern manufacturing?Let’s delve into history to explore how it is born and why it continues to dominate as a leading choice of people.
Stamping and pressing
A metal press work
According to Wang&Budiansky(1978) and Wikipedia,metal stamping is a forming process in which external forces are applied to different raw materials(like sheet metal and extrude).Given the different materials,metal stamping can be classified as sheet metal press,stripe press,pipe press and profile press,each of which is tapped in different industries.With metal stamping,materials can be formed plastically so that we can obtain metal stamping kit with the required shape and size.
What’s more, stamping is a production technology that uses the power of metal press machines to realize the convert of raw materials.It is classified according to temperature into hot stamping and cold stamping. The former is suitable for processing sheet metal with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a common stamping method for thin sheets. Unlike hot pressing, cold pressing enhances material strength through work-hardening.So this method is widely used in industry where the strength of prodcuts is emphasized.
A quick and precision work
Metal stamping is renowned for its high speed.With the help of computer program,one part can be produced in less than 1 second,which spares the possible time loss caused by human energy drainage.This completely-programmed procedure also favors large-scale production,for machines can produce products themselves as long as sufficient raw materials are provided.
Besides,thanks to the automation,each component is produced in a standardized way.By this mean,any mistakes caused by human craftwork can be stripped,accordingly manifesting the high precision of metal stamping.
Applications across industries
Because of various advantages metal stamping possesses,so this manufacturing process is widely used by automotive industry,which focuses on large-batch production.For example,auto parts,like chasis and brake are produced in this way,so that we can enjoy relatively low-price cars with better quality.What’s more electronics also tap this process,for shielding and connectors require high-precision together with relatively low thickness.Only metal stamping can meet for the demand.
Stamping process in manufacturing
Tooling Designs:
Before using metal stamping machines to produce products,the first key process is to design the tooling work.Usually,industry uses software,such as CAD or CAM to design parts going to be manufactured.This process is essential,for all subsequent processes rely on the foundation of it.
Blanking:
It’s the process to procure the raw material before pressing.The process includes cuttings a “blank” from a sheet metal or other materials The size of blank cut depends on size of products you are to produce.Usually,the tolerances are as tight as ±0.001 inches.
Punching:
It’s the process to rework on the raw material to accommodate for some openwork products.The process includes using a punch-and-die to create holes or cutouts.
Bending:
It’s the process to process the raw material according to requirements of products.The process includes forming angles by using V-dies or press brakes.For some simple configuration items,this process is the end of production process.
Coining:
It’s the process to rework on bending parts.The process includes apply high-pressure force on components to create intricate features.This process is key in producing complex products,it builds the strength and configuration of products.
Embossing:
It’s the process to add characters to products.The process includes engraving logos or information about manufacturers on items.
Conclusion
Metal stamping is a cornerstone of modern manufacturing.It balances efficiency, precision and scalability,keeping acting as a good manufacturing way to people. As industries demand lighter, stronger, and more complex parts, advancements in automation and tooling continue to push the application of metal stamping. Whether for automotive innovation or consumer electronics, metal stamping remains indispensable in shaping the world around us.
